Robotic exoskeletons have come a long way, and are even breaking the mold. When one utters the term, it tends to conjure up images of a heavy suit with a metal frame that bestows the wearer super-human strength – as exemplified by Daewoo’s robot worker suits. And whereas those are certainly making an impact, there is a burgeoning market for flexible exoskeletons that would assist with everyday living.
Researchers at Harvard’s Wyss Institute for Biologically Inspired Engineering have developed just such a device, a flexible fabric exoskeleton that earned them a $2.9 million grant by DARPA to continue developing the technology. Unlike the traditional exoskeleton concept, Harvard’s so-called “Soft Exosuit” is not designed to give the wearer vastly increase lifting capacity.
Instead, the Soft Exosuit works with the musculature to reduce injuries, improve stamina, and enhance balance even for those with weakened muscles. In some ways, this approach to wearable robotics is the opposite of past exoskeletons. Rather than the human working within the abilities and constraints of the exoskeleton, the exoskeleton works with the natural movements of the human wearer.
The big challenge of this concept is designing a wearable machine that doesn’t get in the way. In order to address this, the Wyss Institute researchers went beyond the usual network of fabric straps that hold the suit in place around the user’s limbs. In addition, they carefully studied the way people walk and determined which muscles would benefit from the added forces offered by the Exosuit.
With a better understanding of the biomechanics involved, the team decided to go with a network of cables to transmit forces to the joints. Batteries and motors are mounted at the waist to avoid having any rigid components interfering with natural joint movement. This allows the wearer the freedom to move without having to manually control how the forces are applied.
Basically, the wearer does not have to push on a joystick, pull against restraints, or stick to a certain pace when walking with the Exosuit. The machine is supposed to work with the wearer, not the other way around. The designers integrated a network of strain sensors throughout the straps that transmit data back to the on-board microcomputer to interpret and apply supportive force with the cables.
DARPA is funding this project as part of the Warrior Web program, which seeks to reduce musculoskeletal injuries for military personnel. However, Harvard expects this technology to be useful in civilian applications as well. Anyone who needs to walk for long periods of time at work could benefit from the Soft Exosuit, which is less expensive and more comfortable that conventional exosuits; and with a little rescaling, could even be worn under clothing.
But the greatest impact of the Soft Exosuit is likely to be for those who suffer from a physical impairment and/or injuries. Someone that has trouble standing or walking could possibly attain normal mobility with the aid of this wearable robot. And people working their way through physiotherapy would find it very useful in assisting them with restoring their muscles and joints to their usual strength.
The team plans to collaborate with clinical partners to create a version of the exosuit for just this purpose. What the Wyss Institute has demonstrated so far has just been the general proof-of-concept for the Soft Exosuit. In time, and with further refinements, we could see all sorts of versions becoming available – from the militarized to the medical, from mobility assistance for seniors, to even astronauts looking to prevent atrophy.
And as always, technology that is initially designed to assist and address mobility issues is likely to give way to enhancement and augmentation. It’s therefore not hard to imagine a future where soft robotic exosuits are produced for every possible use, including recreation and transhumanism. Hell, it may even be foreseeable that an endoskeleton will be possible in the not-too-distant future, something implantable that can do the same job but be permanent…
Cool and scary! And be sure to check out this video from the Wyss Institute being tested:
This summer, the World Cup 2014 will be taking place in Sao Paulo, Brazil; an event that is sure to be a media circus. And to kick off this circus (no pun!), FIFA has decided to do something rather special. This will consist of a paralyzed teenager making the ceremonial first kick, courtesy of an exoskeleton provided by The Walk Again Project. In addition to opening the games, this even will be the first time that a mind-controlled prosthetic will ever be used in a sporting event.
Though the teenager in question remains to be chosen, the event is scheduled and the exoskeleton tested and ready. Using metal braces that were tested on monkeys, the exoskeleton relies on a series of wireless electrodes attached to the head that collect brainwaves, which then signal the suit to move. The braces are also stabilized by gyroscopes and powered by a battery carried by the kicker in a backpack.
The Walk Again Project, a nonprofit collaboration dedicated to producing full-body mind-controlled prosthetics, represents a collaboration between such academic institutions as Duke University, the Technical University of Munich, the Swiss Federal Institute of Technology in Lausanne, the Edmond and Lily Safra International Institute of Neuroscience of Natal in Brazil, the University of California at Davis, the University of Kentucky, the Duke Immersive Virtual Environment facility.
Miguel Nicolelis, the Brazilian neuroscientist at Duke University who is leading the Walk Again Project’s efforts to create the robotic suit, had this to say about the planned event:
We want to galvanize people’s imaginations. With enough political will and investment, we could make wheelchairs obsolete.
Nicolelis is a pioneer in the field of mind-controlled prosthetics. In the 1990s, he helped build the first mind-controlled arm, which rats learned to manipulate so they could get a drink of water, simply by thinking about doing so. In that project, an electronic chip was embedded in the part of each rodent’s brain that controls voluntary muscle movements. Rows of wires that stuck out from the chip picked up electrical impulses generated by brain cells and relayed those signals to a computer.
Researchers studied the signals as the rats pushed a lever to guide the arm that gave them water, and they saw groups of neurons firing at different rates as the rats moved the lever in different directions. An algorithm was developed to decipher the patterns, discern the animal’s intention at any given moment and send commands from the brain directly to the arm instead of to the lever. Eventually, the rats could move the arm without pushing the lever at all.
Using similar brain-machine interfaces, Nicolelis and his colleagues learned to translate the neural signals in primate brains. In 2000, they reported that an owl monkey connected to the Internet had controlled an arm located 600 miles away. Eight years later, the team described a rhesus monkey that was able to dictate the pace of a robot jogging on a treadmill half a world away in Japan.
Small groups of neurons, it seems, are surprisingly capable of communicating with digital devices. Individual cells learn to communicate with computer algorithms more effectively over time by changing their firing patterns, as revealed in a study of a mouse’s brain published last year in Nature. This capacity for extensive plasticity and the ability to learn comes in quite handy when designing a prosthetic.
German-made sensors will relay a feeling of pressure when each foot touches the ground. And months of training on a virtual-reality simulator will have prepared the teenager — selected from a pool of 10 candidates — to do all this using a device that translates thoughts into actions. In an interview with New Scientist, the lead robotic engineer Gordon Cheng of the Technical University of Munich gave some indication of how the suit works
The vibrations can replicate the sensation of touching the ground, rolling off the toe and kicking off again. There’s so much detail in this, it’s phenomenal.
Capitalizing on that adaptability, several human quadriplegics have received implanted brain chips in FDA-approved clinical trials. One of the first was Matt Nagle, who lost the use of his extremities after being stabbed in the spine. With the aid of electrodes placed in his brain at Brown University in 2004, he learned to raise, lower and drop a piece of hard candy using a primitive jointed arm not connected to his body.
In a widely publicized demonstration of that system, now owned by a company called BrainGate, a 58-year-old woman paralyzed by a stroke sipped a cup of coffee last year using a five-fingered robotic arm not attached to her body. Despite the slickness of the presentation, however, the woman actually had little control over the arm. Despite it being aesthetically pleasing, the design was a little rudimentary.
However, things have come a long way since then thanks to ongoing research, development and testing. In Nicolelis’s lab, monkeys showed the ability to feel virtual objects displayed on a computer screen when areas of the brain associated with the sense of touch were stimulated. The blueprints for next summer’s soccer exoskeleton include similar sensors that will provide an artificial skin for its human wearer, thus ensuring that they can both move the device and receive sensory feedback.
With the world watching, Nicolelis hopes not only that his “bionic teenager” will be able to feel the ball but also that disabled people everywhere will feel a sense of hope. And why wouldn’t they? In this single, incredibly high-profile event, millions of people around the world who struggle with disabilities will witness something truly inspirational. A paralyzed teenager will rise from a wheelchair, kicks the World Cup ball, and bring countless millions to their feet.
And you’re waiting until June of 2014 to see this momentous event for yourselves, be sure to check out this promotional video from The Walk Again Project, featuring interviews with the people who made it happen and showcasing the exoskeleton itself:
3-D printing is leading to a revolution in manufacturing, and the list of applications grows with each passing day. But more important is the way it is coming together with other fields of research to make breakthroughs more affordable and accessible. Nowhere is this more true than in the fields of robotics and medicine, where printing techniques are producing a new generation of bionic and mind-controlled prosthetics.
For example, 3D Systems (a an additive manufacturing company) and EksoBionics (a company specializing in bionic prosthetic devices) recently partnered to produce the new “bespoke” exoskeleton that will restore ambulatory ability to paraplegics. The prototype was custom made for a woman named Amanda Boxtel, who was paralyzed in 1992 from a tragic skiing accident.
Designers from 3D Systems began by scanning her body, digitizing the contours of her spine, thighs, and shins; a process that helped them mold the robotic suit to her needs and specifications. They then combined the suit with a set of mechanical actuators and controls made by EksoBionics. The result, said 3D Systems, is the first-ever “bespoke” exoskeleton.
Intrinsic to the partnership between 3D Systems and EksoBionics was the common goal of finding a way to fit the exoskeleton comfortably to Boxtel’s body. One of the greatest challenges with exosuits and prosthetic devices is finding ways to avoid the hard parts bumping into “bony prominences,” such as the knobs on the wrists and ankles. These areas as not only sensitive, but prolonged exposure to hard surfaces can lead to a slew of health problems, given time.
As Scott Summit, the senior director for functional design at 3D Systems, explained it,:
[Such body parts] don’t want a hard surface touching them. We had to be very specific with the design so we never had 3D-printed parts bumping into bony prominences, which can lead to abrasions [and bruising].
One problem that the designers faced in this case was that a paralyzed person like Boxtel often can’t know that bruising is happening because they can’t feel it. This is dangerous because undetected bruises or abrasions can become infected.In addition, because 3D-printing allows the creation of very fine details, Boxtel’s suit was designed to allow her skin to breathe, meaning she can walk around without sweating too much.
The process of creating the 3D-printed robotic suit lasted about three months, starting when Summit and 3D Systems CEO Avi Reichenthal met Boxtel during a visit to EksoBionics. Boxtel is one of ten EksoBionics “test pilots”, and the exoskeleton was already designed to attach to the body very loosely with Velcro straps, with an adjustable fit. But it wasn’t yet tailored to fit her alone.
That’s where 3D Systems came into play, by using a special 3D scanning system to create the custom underlying geometry that would be used to make the parts that attach to the exoskeleton. As Boxtel put it:
When the robot becomes the enabling device to take every step for the rest of your life. the connection between the body and the robot is everything. So our goal is to enhance the quality of that connection so the robot becomes more symbiotic.
And human beings aren’t the only ones who are able to take advantage of this marriage between 3-D printing and biomedicine. Not surprisingly, animals are reaping the benefits of all the latest technological breakthroughs in these fields as well, as evidenced by the little duck named Dudley from the K911 animal rescue service in Sicamous, Canada.
Not too long ago, Dudley lost a leg when a chicken in the same pen mauled him. But thanks to a 3-D printed leg design, especially made for him, he can now walk again. It was created by Terence Loring of 3 Pillar Designs, a company that specializes in 3D-printing architectural prototypes. After hearing of Dudley’s plight through a friend, he decided to see what he could do to help.
Unlike a previous printed limb, the printed foot that was fashioned for Buttercup the Duck, Loring sought to create an entire limb that could move. The first limb he designed had a jointed construction, and was fully 3D-printed in plastic. Unfortunately, the leg broke the moment Dudley pit it on, forcing Loring to go back to the drawing board for a one-piece printed from softer plastic.
The subsequent leg he created had no joints and could bend on its own. And when Dudley put it on, he started walking straight away and without hesitation. Issues remain to be solved, like how to prevent friction sores – a problem that Mike Garey (who designed Buttercup’s new foot) solved with a silicone sock and prosthetic gel liner.
Nevertheless, Dudley is nothing if not as happy as a duck in a pond, and it seems very likely that any remaining issues will be ironed out in time. In fact, one can expect that veterinary medicine will fully benefit from the wide range of 3D printed prosthetic devices and even bionic limbs as advancement and research continues to produce new and exciting possibilities.
And in the meantime, enjoy the following videos which show both Amanda Boxtel and Dudley the duck enjoying their new devices and the ways in which they help bring mobility back to their worlds:
Last weekend, while the wife, our friend and I were all watching the new Star Trek movie, a number of trailers came on that made us antsy for other “coming attractions”! One of them was one I instantly recognized and began saying the title of long before they flashed it across the screen. Months back, when this movie was first announced, I posted the trailer here because it looked to have all the things I love in sci-fi story. And they have since come out with a longer, more detailed trailer which I share now…
Elysium tells the story of a dystopian future, set in 2154, where the wealthy and privileged live in an orbital colony that is peaceful, serene, idyllic, and sees to all their needs (and looks a lot like the station from Space Odyssey). Meanwhile, the remaining 99% of humanity live planetside, where pollution, environmental collapse and economic ruin have made Earth into a veritable hellhole.
Enter into this Max De Costa (played by a cueballed Matt Damon), a man who is near death who comes to learn of a secret that could topple the whole system and achieve a degree of social justice. In order to do this, he has to break into Elysium, a facility that is heavily guarded and run by Secretary Rhodes (Jodie Foster), and undergoes a radical surgery to get an exoskeleton and some powerful weaponry permanently attached.
Directed by Neil Blomkamp – the South-African director who brought us District 9 and provided visual effects for such shows as Star Gate: SG-1, Smallville and Dark Angel – this movie clearly boasts the same kind of gritty, realistic texture he has come to be known for. And after the 2008 Financial Crisis and the subsequent Occupy Movement, it’s message is pretty timely and likely to be well-received.
As for me? You can keep your social commentary and comparisons to other movie franchises, I wanna see me some exoskeleton battles! Enjoy the trailer:
Robotics has come a long way in recent years. Why, just take a look at NASA’s X1 Robotic exoskeleton, the Robonaut, robotaxis and podcars, the mind-controlled EMT robot suit, Stompy the giant robot, Kenshiro and Roboy, and the 3D printed android. I suppose it was only a matter of time before the world of fashion looked at this burgeoning marketplace and said “me too!”
And here are just some of the first attempts to merge the two worlds: First up there’s the robot mannequin, a means of making window shopping more fun for consumers. Known as the MarionetteBot, this automaton has already made several appearances in shops in Japan and can expected to be making debut appearances across Asia, in North America and the EU soon enough!
Check out the video below to see the robot in action. Designed by the Japanese robotics company United Arrows, the mannequin uses a Kinect to capture and help analyze the movements of a person while a motor moves a total of 16 wires to match the person’s pose. Though it is not yet fast or limber enough to perfectly mimic the moves of a person, the technology shows promise, and has provided many a window-shopper with plenty of entertainment!
And next up, there’s the equally impressive FitBot, a shape-shifting mannequin that is capable of emulating thousands of body types. Designed by the British virtual shopping company Fits.Me, the FitBot is designed to help take some of the guesswork out of online shopping, where a good 25% of purchases are regularly returned because they were apparently the wrong size.
But with the FitBots, along with a virtual fitting room, customers will be able to see right away what the clothes will look like on them. The only downside is you will have to know your exact measurements, because that’s what the software will use to adjust the bot’s body. Click here to visit the company’s website and see how the virtual fitting room works, and be sure to check out there video below:
What does the future hold for the fashion industry and high-tech? Well, already customers are able to see what they look like using Augmented Reality technology displays, and can get pictures thanks to tablet and mobile phone apps that can present them with the image before making a purchase. Not only does it take a lot of the legwork out of the process, its much more sanitary as far as trying on clothes is concerned. And in a world where clothing can be printed on site, it would be downright necessary.
But in the case of online shopping, its likely to take the form of a Kinect device in your computer, which scans your body and lets you know what size to get. How cool/lazy would that be? Oh, and as for those AR displays that put you in the clothes you want? They should come with a disclaimer: Objects in mirror are less attractive than they appear!
Back in October, some rather interesting news came out of Japan. It appears that a research company known as Cyberdyne produced a robot suit named HAL. No joke, the company is seriously named after the company from Terminator franchise that developed Skynet and the robot suit – who’s name stands for Hybrid Assisted Limb – is named after the HAL 9000 from 2001: A Space Odyssey.
Still, the company is the legit and the new robotic suit is quite impressive. Like many before it, it is a powered suit that gives the wearer enhanced strength and protection. But unlike previous models, this one comes equipped with a network of sensors that monitor the electric signals coming from the wearer’s brain, allowing them to seamlessly control the suit’s movements.
This is expected to remedy a problem which has plagued exoskeletons since their inception, which is the problem of speed. While all exos allow for greater strength and load-bearing capacity, the motors that power the limbs tend to respond slowly to the users commands. By anticipating the wearer’s movements by reading them directly from the brain, this new suit will be able to move in synchronicity with the wearer’s limbs.
The suit is also expected to be helpful with Japan’s ongoing cleanup efforts with the crippled Fukushima nuclear power plant. In addition to the new mind-control interface, the suit’s load-bearing capacities are expected to come in handy for workers who are forced to wear a 60 kg (132 lbs) tungsten vest while working in radiation zones. Even for a husky man, that’s quite the load to bear on top of all the additional weight they’ll need to be carrying.
Naturally, there are anticipated hazards as well, like what will happen if the power supply were to suddenly run out. Essentially, the wearer would be trapped inside. However, these and other bugs are expected to be addressed before any units are pressed into service. And with luck, suits like these could available for HazMat workers, construction crews, and people who work in dangerous conditions in just a few years time.
It may not be Iron Man, but it’s certainly a step in that direction. It’s known as the X1 Robotic Skeleton, a spinoff of their earlier Robonaut 2 project. Designed specifically to assists astronauts with either exercising in space, performing difficult tasks, or restoring movement to astronauts who have suffered from paralysis, the X1 is a big leap forward in terms of ergonomics and man-machine interface.
The exoskeleton is powered by four motorized joints and six passive joints, all of which give the 57 pound suit a good range of motion. When set to exercise mode, it provides resistance to the astronauts movement, ensuring that their muscles get the exercise they need while in zero-g environments. The rest of the time, the motors provide enough force to allow an astronaut to get a full range of motion and maintain full ambulatory capabilities.
A joint effort between NASA, The Florida Institute for Human and Machine Cognition, and the awesomely named Oceaneering Space Systems, the X1 is still deep in the research and development phase. Still, the suit could some day be used both in space and on Earth. In that respect, it is not unlike ReWalk and other robotic systems that are currently employed by the military which are used to help restore motion to the paralyzed and assist people in power lifting. Soon, the word “disability” will be entirely without meaning and “power lifters” will have to be redefined!
Check out this video of the X1 in action and/or click on the link below for more on this story.
As Smith said that ambiguous sequel known as Matrix: Reloaded, “More!” And what better way to start this latest list off than with an example from that franchise…
Starting off today’s list is the Armored Personnel Unit (or APU) from the Matrix trilogy. Making it’s first appearance in Matrix: Reloaded, it’s real c0ntribution came in Revolutions when every single unit in existence was used in the defense of Zion.
Hydraulically operated, the APU was run by a single operator who sat in a central cage and operated everything through a series of hand controls and leg straps, much like the Cargo Loader from Aliens.
It’s weaponry consisted of two 30mm cannons which are mounted on the arms. Loading these weapons required the assistance of an ammo carrier who would feed the ammo boxes into the back with the assistance of the APU’s crane. Due to its flexible reach, a single APU could defend itself from multiple Sentries without much difficulty.
During the battle for Zion, some 350 APU’s took part in the defense. Unfortunately, they faced overwhelming odds and all were lost. Though some were still functional even after their pilots died, their systems were rendered inoperative after the Hammer arrived on scene and detonated its EMP device.
This next example comes once again from the manga and anime world of Full Metal Panic. Officially, the name “Arm Slave” is short for Armored Mobile Master-Slave System, referring to their coordinated unidirectional control system. Basically, this means that a single pilot would be controlling multiple suits, either from inside a command mecha or from a remote location.
Built by the US in the fictional FMP universe, these powered suits went on to become the mainstay in every western army, giving new meaning to the term “mechanized infantry”. However, these mecha were featured chiefly as the weapons of Amalgam and Mithril, organizations to whom the main characters were members.
In the course of the story, every state produced its own variations of the Arm Slave and the design went through several generations. Beginning as smaller variants powered by internal combustion engines, the later models would feature cold fusion reactors and electroactive polymer muscles, making them faster, more mobile, and capable of much better performance. In terms of weapons, the Arm Slave is limited only to what it can carry, making many different configurations possible.
These include, but are not limited to, two 12.7 mm chain guns, two XM18 wire guns, a single 40, 57, or 70 mm smooth-bore cannon, a single missile launcher, or hand to hand weapons such as the M1108 anti-tank dagger or the GRAW-2 Monomolecular cutter. And given its raw power and strength, it can also attack with its bare hands and just bash things to death. Good to have options!
AT-ST: The other famous walker from the original Star Wars universe! Designated as the All Terrain Scout Transport, the AT-ST was a bipedal walker that was created by the Republic for use in the Clone Wars, but saw more extensive service with the Empire during the Galactic Civil War.
Appearing in both Empire and Jedi, the scout walker was basically the reconnaissance version of the AT-AT, often serving in a support capacity during major assaults. However, in situations where the terrain was more dense and difficulty to navigate, as was the case with Endor, the AT-ST was considered more favorable. Hence why the Imperial garrison chose to deploy several in the field while keeping their AT-AT closer to the shield generator station itself.
In terms of armaments, the AT-ST carried a twin-blaster cannon on the front of its module, along with a light twin blaster and a concussion grenade launcher mounted one either side. While relatively fast and able to negotiate Endor’s heavily wooded terrain, its bipedal configuration and relatively thin armor made it vulnerable to the Ewok’s log traps.
Two were destroyed in this way, while another was commandeered by Chewi and two Ewoks and used to destroy a fourth. Without any walker remaining to provide cover, the garrison was quickly routed and all their speeders destroyed. Not a very good record of service, being beaten by furry wooded creatures and their flying logs!
Back to the good ol’ universe of Warhammer 40k with another installment! And this time around, boy did we bring out the heavy hitters! Here we have the Dreadnought, a heavy cybernetic mecha that is similar in concept to the Dragoon and Immortal from Starcraft.
Basically, whenever a Space Marine is mortally wounded in combat, they can have their remains transferred into one of these behemoths so they can keep on fighting. Entombed within the unit ceramite skin, the pilot controls the Dreadnought through a series of neural links from a command “sarcophagus”.
As a heavy mech, the Dreadnought’s primary function is that of infantry support. Its weaponry can take many different configurations, but often involves laser or gatling cannons mounted in the arms, missile launchers embedded in the shoulders, and additional launchers or cannons mounted over the head. Smaller weapons are generally mounted under the upper body for point-defense against lighter infantry as well.
Enhanced Powered Armor: This next example comes from the F.E.A.R. gaming universe. Known as EPA’s, these bad boys are the latest generation of powered armor to come from this universe and are by far the biggest and baddest of the bunch!
Much like its predecessor, the Elite Powered Armor, the Enhanced was designed for combat against both infantry and vehicles. For these purposes, it is armed with two GAU-19/A heavy rotary machine guns, one on each arm. In addition, it has three sets of rocket launchers, mounted in the shoulders and above the right arm, that launch homing missiles.
For strictly defense and maintenance purposes, the EPA also has an automatic repair system which activates when the unit is heavily damaged and a new shielding system. Although it does not have the ability to engage in melee attacks with its hands, it is still capable of generating powerful stomp attacks with its feet that send powerful shockwaves in all directions. Because of their power and obvious expense, these units are rarely encountered in the game, and only ever at the end of a level.
Gun X Sword: Back to the world of anime, this time for a robot that puts the swash in swashbuckling! Officially known as “Dann of Thursday”, this mecha comes from the anime of the same name and was the personal powered armor of Van, the show’s main protagonist.
Built to resemble its user, who is also tall and lanky, this mecha is unique amongst its peers in that it has no ranged weapons. All its capabilities revolve around its central blade, which while in compact form, causes the mech to resemble a giant sword. When in humanoid form, this blade can be wielded as a single sword, or broken down for use as two.
In additi0n, Dann has also has an electromagnetic shield which protects it from ranged attacks. This allows van to close ranks with enemy mechs and eviscerate them with his blades. But by far, the Dann’s greatest feature is its ability to heal its pilot once they enter the cockpit. Pretty handy when you need to recover from some wounds, or just shrug off a hangover!
Iron Giant: There’s something to be said about a gentle giant, even if he is 40 feet tall and made out of solid metal. Taken from the 1999 Disney movie of the same name, the Iron Giant is distinguished amongst its peers here in that it is not only an alien machine, but a sentient one. As such, it is as much at home on a list of AI’s as it is giant robots.
Apparently, this robot was meant for first contact purposes, possessing the ability to learn and boasting some rather impressive defensive protocols. When activated, these weapons are capable of evaporating tanks, aircraft and entire platoons of infantry. However, as was demonstrated, these only become active when the robot is threatened, or he becomes angry.
And few things make an Iron Giant more angry than threatening his best friend in the world, which in this case was the little boy Hogarth Hughes. In addition to seeing past his massive metal frame, Hogarth taught him how to understand English and acted as his guide to the confusing world of humans.
Above all, the Iron Giant demonstrated a tremendous capacity for emotion. Aside from anger, he also demonstrated love, attachment and empathy. This last aspect was demonstrated when he chose to sacrifice himself rather than bring destruction down on the town of Rockwell (obvious allusion to Roswell). Having learnt that a nuclear missile was heading for him, he chose to fly away to intercept it rather than let it destroy everything and everyone around him. So sad when gentle giants are misunderstood!
Nova (Black Hawk):
Back to Battltech, once again for an Omnimech that is the workhorse of the Clans that employ it. Known as the Nova by its inventors, it also bears the name of Black Hawk by the Inner Sphere who captured one and began producing their own variants of it.
Designed initially for infantry support, the Nova was unique in that it was built with hardpoints which allowed infantry soldiers to easily mount and dismount. As such, the Nova could function as a mech and a sort of battle taxi, ferrying infantry into battle alongside it.
In terms of armaments, the Nova was again unique in that it could be armed exclusively with energy weapons, 12 of them to be exact. However, in other configurations, it could be outfitted with machine guns, autocannons, gauss rifles, or even a sword. These would be mounted almost entirely on its arms, but also in two large clusters around the head.
Unfortunately, production of this model soon ceased after a unit was captured by Inner Sphere forces and duplicates fashioned. Believing that their mech design had been compromised, the Clans began to focus on other models to serve as their omnimechs of choice.
Sentinels: This example is kind of obvious, surprised I didn’t think of it sooner. While I was never much of a fan of the comics, I did see a few episodes of the animated show, and these things certainly made an appearance! As a potential shout out, they were also featured in the movie X-Men: The Last Stand, appearing in the Danger Room as a simulation.
In the comic books and animated series, however, these massive robots made several appearances and were quite important to the overall story. Designed for hunting mutants, the Sentinels went through several different models. However, the most common were three stories tall, capable of flight, employed energy weapons, and had advanced sensors which could detect mutants.
In addition, their programming ran from the semi-intelligent, involving advanced tactical thinking and decision-making skills, to the fully self-aware. But of course, these were few in number, usually designed for the sole purpose of commanding other Sentinels (such as the Master Mold). Many Sentinels were designed to be capable of learning from their engagements, adjusting strategies to deal with mutants of varying ability.
Often serving as the antagonists in the X-Men universe, these robots were nothing if not a prime example of terrifying gigantism! Can’t believe I didn’t think of them sooner!
VF-0 Pheonix: And last, but certainly not least, we return to the Macross universe for another example of an over-sized mecha! In this case, we have what’s known as a variable fighter, which is basically a mecha that is capable of transforming from an aircraft to a humanoid form.
As part of Earth’s plan to counter a Zentraedi invasion, the Pheonix was a merger of fighter designs with Overtechnology. Composed of titanium/carbon composite, space metal alloy and SWAG energy converting armor, this mecha is capable of operating in space, upper atmospheres, lower atmospheres and even underwater. It’s clipped wing air design also ensures a great deal of maneuverability when in flight mode.
In terms of armaments, the Pheonix prefers energy weapons to autocannons due to a lack of internal storage space. As a result, it comes equipped with either one VF-0A/D or two VF-0S fixed Mauler laser cannons, and multiple micro-missile launchers mounted in the shoulders and chest. In flight mode, it is also capable of carrying a GPU-9 35 mm gatling gun pod and up to twelve air to air or air to ground missiles or guided munitions.
The Pheonix also comes with the added feature of being able to carry reactive armor for added protection. In fighter mode, it has two seats, one for the pilot and one for a radar engineer, similar to the F-14 Tomcat. And like most variable fighters, it can also deploy in GERWALK mode (or Ground Effective Reinforcement of Winged Armament with Locomotive Knee-joint ), a sort of half-fighter, half humanoid configuration which allows for ground assaults and quick take off.
