HONDA has unveiled a new walking assist machine designed to make it easier for the elderly to climb stairs and help factory workers.

The computerised leg device is the latest addition to walking technology developed by the Japanese automaker, which announced the world's first two-legged walking robot, ASIMO, in 2000.

The 6.5kg device - consisting of a saddle, leg-like frames and shoes - can reduce the load on users' legs while walking or climbing and descending stairs by supporting bodyweight, Honda said.

Honda said the motor-powered machine is still at an experimental stage, but elderly people and people undergoing rehabilitation who need support for their leg muscles and joints are the main target.
