Robot built to walk like senior citizens

Tokyo (UPI) Dec 22, 2010

HRP-2 acts more like a human, placing both arms on a table to maintain its balance when trying to sit down in a chair or using one arm for support when taking a big swinging kick at a ball, the researchers say.

Robots have been made to run, jump and even dance, but they might be more useful if they could walk like a senior citizen, Japanese researchers say.

Scientists at Japan's National Institute of Advanced Industrial Science and Technology have developed a robot that leans on objects in its environment to support itself as it moves around and completes tasks, reported Wednesday.

"Roboticists usually just see objects as obstacles to be avoided," the institute's Sebastien Lengagne says. "But they can help us."

Lengagne and his colleagues are developing humanoid robots capable of using their entire bodies and any surrounding objects to move around cluttered environments and complete complex balancing tasks without getting stuck or falling over.

"If I ask you to look below your desktop, you will put your hand on the desktop for support," Lengagne says. "But most methods will try to get the robot to do the task without touching the desktop."

The robot, HRP-2, acts more like a human, placing both arms on a table to maintain its balance when trying to sit down in a chair or using one arm for support when taking a big swinging kick at a ball, the researchers say.

Robot Arm Improves Performance Of Brain-Controlled Device
Chicago IL (SPX) Dec 20, 2010
The performance of a brain-machine interface designed to help paralyzed subjects move objects with their thoughts is improved with the addition of a robotic arm providing sensory feedback, a new study from the University of Chicago finds. Devices that translate brain activity into the movement of a computer cursor or an external robotic arm have already proven successful in humans. But in ... read more
