Robot suit to aid the aged and disabled

Tokyo: Japanese companies are preparing for the commercial launch of a “robot suit” that helps aged or physically disabled people walk, get up the stairs or seat themselves to relax without a chair.

Trading house Mitsui and Co. and some 30 other Tokyo firms plan to set up a joint venture in April or May next year to market the powered suit developed by Yoshiyuki Sankai, professor and engineer at Tsukuba University officials said Thursday.

“This is neither a robot in machine factories nor a one for amusement like a pet robot. This is a brand-new proposal projecting a future image of relations between people and robots,” Sankai said.

The powered suit, code- named HAL-3 (Hybrid Assistive Leg), consists of a computer and batteries in the backpack as well as four actuators attached around the knees and hip joints. The motor-powered devices guide movement of the legs as the computer calculates the user’s next motion by detecting faint electric signals from the muscle, the professor said.

With the equipment, the user can walk at a speed of four kilometers (2.5 miles) per hour with little physical exertion and avoid the jerky stop-go moves of ordinary robots.

As a first step, the new venture plans to lease or sell 10 prototypes next year, targeting hospitals and nursing-care facilities at home and abroad, Sankai said.
