“MIT reveals a swarm of autonomous floating robots that can digest an oil spill. The 16-foot robots drag a nanowire mesh that acts like a conveyor belt to soak up surface oil ‘like paper towels soak up water,’ absorbing 20 times its weight and then harmlessly ‘digesting’ the oil by burning it off. Powered by 21.5 square feet of solar panels, the ‘Seaswarm’ robots run on the power of a lightbulb, and with just 100 watts ‘could potentially clean continuously for weeks’ without human intervention, MIT announced. The swarm uses GPS data and communicates wirelessly to move as a coordinated group to ‘corral, absorb and process’ oil spills, and MIT researchers estimate that a fleet of 5,000 could clean up a gulf-sized spill within one month.”

From optimizing truck delivery routes to inspiring nerve-cell-based cognition models, ant intelligence has arrived. From the Economist: ‘In 1992 Dr. Dorigo and his group began developing Ant Colony Optimisation (ACO), an algorithm that looks for solutions to a problem by simulating a group of ants wandering over an area and laying down pheromones. ACO proved good at solving travelling-salesman-type problems. Since then it has grown into a whole family of algorithms, which have been applied to many practical questions. … Ant-like algorithms have also been applied to the problem of routing information through communication networks. Dr. Dorigo and Gianni Di Caro, another researcher at IDSIA, have developed AntNet, a routing protocol in which packets of information hop from node to node, leaving a trace that signals the “quality” of their trip as they do so. Other packets sniff the trails thus created and choose accordingly. In computer simulations and tests on small-scale networks, AntNet has been shown to outperform existing routing protocols.

“The STS-133 crew will deliver robot Robonaut 2 (R2) to the International Space Station. Cocooned inside an aluminum frame and foam blocks cut out to its shape, R2 is heading to the station inside the Permanent Multipurpose Module in space shuttle Discovery’s payload bay. R2, with its humanlike hands and arms and stereo vision, is expected to perform some of the repetitive or more mundane functions inside the orbiting laboratory to free astronauts for more complicated tasks and experiments.”

“Engineers have used a variety of techniques to create robots that can scale walls — the Climber uses a rolling seal, while the insect-like robots from SRI have caterpillar tracks with electro-adhesive properties. While such robots generally focus on speed, adhering to the wall and deciding how and when to move, the creators of a small robot named ROCR say it is the first wall-climbing robot to focus on climbing efficiently. And it does so by using the momentum of a tail that swings like a grandfather clock’s pendulum.”

“The world’s first human testing of a mind-controlled artificial limb is ready to begin. A joint project between the Pentagon and Johns Hopkins Applied Physics Laboratory, the Modular Prosthetic Limb will be fully controlled by sensors implanted in the brain, and will even restore the sense of touch by sending electrical impulses from the limb back to the sensory cortex. Last week APL announced it had been awarded a $34.5M contract with DARPA, which will allow researchers to test the neural prosthetic in five individuals over the next two years.”
