Japanese robot walks like a monkey

It may walk like a Japanese robot, but it's thinking like a monkey in the United States.

Japanese and US researchers said Wednesday they have created a humanoid robot that acts according to the brain activity of a monkey all the way across the Pacific.

The experiment was part of efforts to develop prosthetic limbs which can be mentally controlled by people with disabilities.

A laboratory in the western Japanese city of Kyoto unveiled a 155-centimetre (62-inch) tall humanoid, with a friendly-looking face including bulging black eyes, who walked via signals coming into its legs through wires.

Researchers said the robot was responding to the cortical brain activity of a monkey that was walking attached to wires on a treadmill at Duke University in North Carolina. The signal was sent via the Internet.

"We were able to detect the monkey's brain activity while walking on the treadmill and relay the data from the United States to Japan," the state-backed Japan Science and Technology Agency was quoted by AFP as saying in a statement.
