The Future of Housing: Casa Futebol Concept

casa_futebol_brazilIt’s no secret that Brazil’s decision to host the 2014 World Cup was the source of controversy. With roughly $4 billion spent on renovating and constructing the stadiums needed to host the international event, many wondered why that money could not have been spent addressing other infrastructure concerns – such as providing housing and utilities for its many impoverished citizens.

However, drawing inspiration from the social issues plaguing much of the publicity around the event, a pair of French architects have developed a proposal to re-invent the structures as complexes for low-cost housing. While most of the stadiums constructed for the World Cup will continue to host football matches, Brazil’s local teams stand to draw a fraction of the crowds that attended the event, doing little to assuage concerns of wasted resources.

casa_futebol_brazil-1Other buildings, such as the Arena da Amazonia, face a less certain future. Located in the jungle city of Manaus, the 44,500 seat stadium is perhaps the most contentious of Brazil’s World Cup creations. A local judge proposed converting it into a center for temporary detainees to tackle the city’s overflowing prisons, though this was met with fervent opposition from government officials.

The proposal by Axel de Stampa and Sylvain Macaux is perhaps the most ambitious. Dubbed Casa Futebol, it involves transforming each of the 12 World Cup Stadiums into affordable housing for Brazil’s poor and displaced. As Stampa explained in an interview with Gizmag:

The project covers 12 Brazilian stadiums. There are actually six stadiums where we can colonize the exterior facade. Five of these have an exterior structure composed of concrete and metal columns separated by seven or eight meters (23 to 26 ft). We just have to insert pre-fabricated housing using the existing structures.

casa_futebol_brazil-2The remaining stadiums would see housing modules that are 105 m2 (1,130 ft2) fitted to the interior at the expense of rows of seating, the only difference between these and those receiving exterior additions being the installation process. Conscious of Brazil’s adoration for the world game, the proposal would see the stadiums altered slightly, but continue to host matches with profits going towards ongoing maintenance and construction of the housing.

The project is based on modular pre-fabricated houses. So the only thing that changes is the implantation of the houses… We think that the concept is achievable in all 12 stadiums. You just have to take up some seating and reduce their capacity a little bit.

The team guesses that if converted, the stadiums could each house between 1,500 and 2,000 people per building, and a total of approximately 20,000 across the entire project. This bold proposal for Brazil’s stadiums forms part of a year-long architecture project called 1 week 1 project, where the pair endeavor to produce spontaneous architecture projects every week for one year.

casa_futebol_brazil-4While they don’t have current plans to take the Casa Futebol beyond the concept stage, it is hoped that the project can inspire more socially-conscious approaches to problems of this kind. Combined with 3-D printed housing and other prefab housing projects, this kind of re-purposing of existing infrastructure is a way of addressing the problem of slums, something which goes far beyond the developing world.

World Cup 2014 to Open with Exoskeleton Kick

WorldCup_610x343This 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.

ReWalk1The 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.

miguelnicolelis_secom508x339Nicolelis 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.

neuronsUsing 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.

exoskeleton_FIFA2014German-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.

woman-robotic-arm_650x366In 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.

Walk-Again-Project-Kick-Ball-537x358With 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:
