This has to be one of the most inspiring short films of the year. Erik Wernquist = a digital artist and animator from Stockholm, Sweden – released this movie this past fall, and its made quite the impact already! Addressing the idea of future space exploration, Wernquist uses stunning visuals to show how human beings may one day fly to Jupiter, float walk on the surface of Mars, skate on the frozen surfaces of Europa, and fly through the skies of Titan.

One thing I myself loved was the attention to detail and little accuracies. Within each impressive visual, there are hints that give away the locations. For example, the blue sunset is from Mars, as pictured by NASA’s many rover missions over the past few years. The frozen lake where people are skating on shows Jupiter looming in the sky, indicating that it is Europa. And an overhead shot of Titan shows the “Mini Nile River” observed there by the Cassini space probe. And while the asteroid is unnamed, I would bet dollars to donuts that Vesta!

Including in these visuals are a number of speculative science fiction ideas pioneered by writers like Arthur C. Clarke and Kim Stanley Robinson, not the least of which have to do with space elevators and habitats built into hollowed-out asteroids. But above all is the contribution of Carl Sagan, who’s narration from his own book “Pale Blue Dot: A Vision of the Human Future in Space” (1994) provides the voiceover for the film.

Archer Season 6 Trailer

archer-fxIf, like me, you’re a fan of the show Archer, you’ve been wondering when the hell Season 6 is going to premiere. Luckily, FX released the first season 6 trailer a few weeks ago, and indicated that new episodes will be on the air starting in January. That’s good news, for those of us who’ve been waiting since April to find out what’s coming next and when.

Who do you think you are, you Archer producers, Game of Thrones?

To be fair, a couple of hints have been leaked over the past few months as to what will be happening in the new season. For starters, it’s been made clear that after events in the last season, the spy agency will be back at work. Only this time around, they’ve dropped the name ISIS thanks to a certain group of terrorists scumbags who’ve been roving around Iraq and Syria of late.

Second, Lana is busy raising her and Archer’s daughter, Pam is off the wagon as far as binge-eating goes (at least she kicked her massive cocaine habit), and everybody else is pretty much the same. Cheryl is a pyromaniac, Cyril is a boring accountant, Ray is a champion skier, Krieger is still trying to master YYZ, and Malory is still a horrible shrew.

Just a few more months, people!

Star Wars: Episode VII – The Force Awakens Trailer!

star-wars-episode-vii-force-awakensIt finally happened, Lucasarts and J.J. Abrams have released the very first trailer for the upcoming Star Wars sequel. For months, tidbits of news has been trickling out of the studio – casting info, tentative info on the plot, official posters; and of course, the name. But otherwise, everyone involved in the movie’s production has been pretty tight-lipped about it.

Word is, the studio even ordered a “drone shield” to protect their sets from anyone trying to obtain aerial footage of the production. Pretty neat huh? In any case, the trailer is pretty good at giving us drops that will only make us thirsty for more!

Star-WarsVIIThese include the familiar locale of Tatooine, actor John Boyega in the role of a Stormtrooper, a Sith with a newfangled lightsaber (above), actress Daisy Ridley riding a bulky speeder on Tatooine, actor Oscar Isaac flying a squad of X-wings across open water, Stormtroopers preparing for an assault, and the good ol’ Millennium Falcon dog fighting with TIE fighters above Tatooine’s surface.

All the while, we hear a baritone voice asking us if we can feel it, and by “it”, he means the Force! I tell you, this puts me in mind of the days when trailers for Star Wars Episode I were first coming out. I remember how us Wars geeks were all atwitter and couldn’t wait to see it. Perhaps it’s because I’m older now, or that the prequels have left me a bit jaded and cynical, but I do wish I could recapture that feeling.

star-wars-episode-vii-force-awakens(1)Basically, I think that like many childhood fans, I’m hoping that these sequels will be what the prequels should have been – an exciting and awesome return to the Star Wars universe we all knew and loved. Before the dark times… before Jar-Jar and midechlorians!

For f*** sakes, MIDECHLORIANS!

The Future is Here: The Soft Robotic Exosuit

aliens_powerloaderRobotic 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.

Exosuit-640x353Instead, 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.

softexosuitWith 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.

Warrior_Web_Boston_Dynamics_sentDARPA 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.

exosuit_cyberdyneHALThe 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:

Judgement Day Update: Cheetah Robot Unleashed!

MIT-Cheetah-05-640x366There have been lots of high-speed bio-inspired robots in recent years, as exemplified by Boston Dynamics WildCat. But MIT’s Cheetah robot, which made its big debut earlier this month, is in a class by itself. In addition to being able to run at impressive speeds, bound, and jump over obstacles, this particular biomimetic robot is also being battery-and-motor driven rather than by a gasoline engine and hydraulics, and can function untethered (i.e. not connected to a power source).

While gasoline-powered robots are still very much bio-inspired, they are dependent on sheer power to try and match the force and speed of their flesh-and-blood counterparts. They’re also pretty noisy, as the demonstration of the WildCat certainly showed (video below). MIT’s Cheetah takes the alternate route of applying less power but doing so more efficiently, more closely mimicking the musculoskeletal system of a living creature.

mit-cheetahThis is not only a reversal on contemporary robotics, but a break from history. Historically, to make a robot run faster, engineers made the legs move faster. The alternative is to keep the same kind of frequency, but to push down harder at the ground with each step. As MIT’s Sangbae Kim explained:

Our robot can be silent and as efficient as animals. The only things you hear are the feet hitting the ground… Many sprinters, like Usain Bolt, don’t cycle their legs really fast. They actually increase their stride length by pushing downward harder and increasing their ground force, so they can fly more while keeping the same frequency.

MIT’s Cheetah uses much the same approach as a sprinter, combining custom-designed high-torque-density electric motors made at MIT with amplifiers that control the motors (also a custom MIT job). These two technologies, combined with a bio-inspired leg, allow the Cheetah to apply exactly the right amount of force to successfully bound across the ground and navigate obstacles without falling over.

MIT-cheetah_jumpWhen it wants to jump over an obstacle, it simply pushes down harder; and as you can see from the video below, the results speak for themselves. For now, the Cheetah can run untethered at around 16 km/h (10 mph) across grass, and hurdle over obstacles up to 33 centimeters high. The Cheetah currently bounds – a fairly simple gait where the front and rear legs move almost in unison – but galloping, where all four legs move asymmetrically, is the ultimate goal.

With a new gait, and a little byte surgery to the control algorithms, MIT hopes that the current Cheetah can hit speeds of up to 48 km/h (30 mph), which would make it the fastest untethered quadruped robot in the world. While this is still a good deal slower than the real thing  – real cheetah’s can run up to 60 km/h (37 mph) – it will certainly constitute another big step for biomimetics and robotics.

Be sure to check out the video of the Cheetah’s test, and see how it differs from the Boston Dynamics/DARPA’s WildCat’s tests from October of last year:

The Future is Here: Google X’s Delivery Drones

google-x-project-wing-prototypesThere are drones for aerial reconnaissance, drones for domestic surveillance, and drones for raining hell, death and destruction down on enemy combatants. But drones for making personal deliveries? That’s a relatively new one. But it is a not-too-surprising part of an age where unmanned aerial vehicles are becoming more frequent and used for just about every commercial applications imaginable.

After working on secret for quite some time, Google’s secretive projects lab (Google X) recently unveiled its drone-based delivery system called Project Wing. On the surface, the project doesn’t look much different from Amazon’s Prime Air aut0nomous quadcopter delivery service. However, on closer inspection, Project Wing appears to be much more ambitious, and with more far-reaching goals.

Amazon-Google-780x400The original concept behind Project Wing — which has been in development for more than two years — was to deliver defibrillators to heart attack sufferers within two minutes. But after running into issues trying to integrate its tech with the US’s existing 911 and emergency services systems, the focus shifted to the much more general problem of same-day deliveries, disaster relief, and delivering to places that same- and next-day couriers might not reach.

For their first test flights, the Google team traveled to Australia to conduct deliveries of dog food to a farmer in Queensland. All 31 of Project Wing’s full-scale test flights have been conducted in Australia, which has a more permissive “remotely piloted aircraft” (i.e. domestic drones) policy than the US. There’s no word on when Project Wing might be commercialized, but it is estimated that it will be at least a couple of years.

google-drones-290814While most work in small-scale autonomous drones and remotely piloted aircraft generally revolves around quadcopters, Google X instead opted for a tail-sitter design. Basically, the Project Wing aircraft takes off and lands on its tail, but cruises horizontally like a normal plane. This method of vertical-takeoff-and-landing (VTOL) was trialed in some early aircraft designs, but thrust vectoring was ultimately deemed more practical for manned flight.

The Project Wing aircraft has four electric motors, a wingspan of around 1.5m (five feet), and weighs just under 8.6 kg (19 pounds). Fully loaded, the drones apparently weigh about 10 kg (22 pounds) and are outfitted with the usual set of radios and sensors to allow for autonomous flight. But there’s also a camera, which can be used by a remote pilot to ensure that the aircraft drops its package in a sensible location.

google-project-wing-delivery-drone-640x353As you can see from the video below, the packages are dropped from altitude, using a winch and fishing line. Early in the project, Google found that people wanted to collect packages directly from the drone, which was impractical when the engines were running. The air-drop solution is much more graceful, and also allows the drone to stay away from a large variety of low-altitude obstacles (humans, dogs, cars, telephone lines, trees…)

This is another major different with Amazon Prime Air’s drones, which carry their package on the drone’s undercarriage and land in order to make the delivery. And while their octocopters do have slightly better range – 1.6 km (1 mile), compared to Project Wing’s 800 meters (half a mile) – Google is confident its delivery system is safer. And they may be right, since its not quite clear how small children and animals will react to a landing object with spinning rotors!

Google-Wing-3For the moment, Google has no specific goal in mind, but the intent appears to be on the development for a full-scale same-day delivery service that can transport anything that meets the weight requirements. As Astro Teller, director of Google X labs, said in an interview with The Atlantic:

Throughout history there have been a series of innovations that have each taken a huge chunk out of the friction of moving things around. FedEx overnight delivery has absolutely changed the world again. We’re starting to see same-day service actually change the world. Why would we think that the next 10x — being able to get something in just a minute or two — wouldn’t change the world?

Nevertheless, both projects are still years away from realization, as both have to content with FAA regulations and all the red tape that come with it. Still, it would not be farfetched to assume that by the 2020’s, we could be living in a world where drones are a regular feature, performing everything from traffic monitoring and aerial reconnaissance to package delivery.

News from Space: Orion Spacecraft Completed

orion_arrays1NASA’s return to manned spaceflight took a few steps forward this month with the completion of the Orion crew capsule. As the module that will hopefully bring astronauts back to the Moon and to Mars, the capsule rolled out of its assembly facility at the Kennedy Space Center (KSC) on Thursday, Sept. 11. This was the first step on its nearly two month journey to the launch pad and planned blastoff this coming December.

Orion’s assembly was just completed this past weekend by technicians and engineers from prime contractor Lockheed Martin inside the agency’s Neil Armstrong Operations and Checkout (O & C) Facility. And with the installation of the world’s largest heat shield and the inert service module, all that remains is fueling and the attachment of its launch abort system before it will installed atop a Delta IV Heavy rocket.

Orion-at-KSC_Ken-KremerThe unmanned test flight – Exploration Flight Test-1 (EFT-1) – is slated to blast off on December 2014, and will send the capsule into space for the first time. This will be NASA’s first chance to observe how well the Orion capsule works in space before it’s sent on its first mission on the Space Launch System (SLS), which is currently under development by NASA and is scheduled to fly no later than 2018.

The Orion is NASA’s first manned spacecraft project to reach test-flight status since the Space Shuttle first flew in the 1980s. It is designed to carry up to six astronauts on deep space missions to Mars and asteroids, either on its own or using a habitat module for missions longer than 21 days. The development process has been a long time in the making, and had more than its share of bumps along the way.

Orion-at-KSC_Ken-Kremer1As Mark Geyer, Orion Program manager, explained:

Nothing about building the first of a brand new space transportation system is easy. But the crew module is undoubtedly the most complex component that will fly in December. The pressure vessel, the heat shield, parachute system, avionics — piecing all of that together into a working spacecraft is an accomplishment. Seeing it fly in three months is going to be amazing.

In addition to going to the Moon and Mars, the Orion spacecraft will carry astronauts on voyages venturing father into deep space than ever before. This will include going to the Asteroid Belt, to Europa (to see if there’s any signs of life there), and even beyond – most likely to Enceladus, Titan, the larger moons of Uranus, and all the other wondrous places in the Solar System.

oriontestflightThe two-orbit, four and a half hour EFT-1 flight will lift the Orion spacecraft and its attached second stage to an orbital altitude of 5,800 km (3,600 miles), about 15 times higher than the International Space Station (ISS) – and farther than any human spacecraft has journeyed in 40 years. It will be an historic occasion, and constitute an important step in what is sure to be known as the Second Space Age.

And be sure to watch this time-lapse video of the Orion Capsule as it is released from the Kennedy Space Center to the Payload Hazardous Servicing Facility in preparation for its first flight:
