For people confined to wheelchairs, the proliferation of ramps has greatly enhanced their mobility. Unfortunately, opening doors remains an omnipresent, and frustrating, challenge. Oddly enough, opening doors also presents a serious impediment for anthropomorphic robots. Now, robotics engineer Erin Rapacki has solved both problems with a single stroke.

Having one of those days where even a hearty bowl of Fruit Loops and Jack Daniels can't get you out of bed? A telepresence  robot can come into the office for you, elevating telecommuting to a decidedly new level. The somewhat humanoid 'bots, produced by Mountain View, California-based Anybots, are controlled via video-game-like controls from your laptop, allowing you to be "present" without actually being in the office.

The National Science Foundation has awarded almost $1 million to develop a swarm of underwater robotic explorers.

Simulating the brain with traditional chips would require impractical megawatts of power. One scientist has an alternative.

According to Kwabena Boahen, a computer scientist at Stanford University, a robot with a processor as smart as the human brain would require at least 10 megawatts to operate. That's the amount of energy produced by a small hydroelectric plant. But a small group of computer scientists may have hit on a new neural supercomputer that could someday emulate the human brain's low energy requirements of just 20 watts -- barely enough to run a dim light bulb.

Not since RoboCop has being a cyborg seemed so very cool. University of Chicago geoscientists are developing an artificial intelligence system that future Mars explorers could incorporate into their spacesuits to help them recognize signs of life on Mars' barren surface.
