Honda demonstrates walking assist device29 April 2008 Honda Motor Co demonstrated an experimental model of a walking assist device that could support walking for the elderly and other people with weakened leg muscles at the trade fair Barrier Free Equipments & Rehabilitation for the Elderly & the Disabled in Osaka, Japan, last weekend.
The co-operative control technology used in the device was developed by Honda through the cumulative study of human walking, which was also used in the development of Honda's advanced humanoid robot, ASIMO. Applying co-operative control based on the information obtained from hip angle sensors, the motors provide optimal assistance based on a command from the control CPU. With this assist, the user's stride will be lengthened compared to the user's normal stride without the device and therefore the ease of walking is achieved. The compact design of the device was achieved with flat brushless motors and a control system developed by Honda. In addition, a simple design to be worn with a belt around the hip and thigh was employed to help achieve overall weight as light as approximately 2.8kg. As a result, the device reduces the user's load and can be fitted to different body shapes. The device is made in three sizes and is powered by Lithium ion batteries that give 2 hours of assisted walking. Honda's unique walking robot ASIMO (which stands for advanced step in innovative mobility), is designed to help people and is undergoing continued development. It is hoped that it will eventually assist the elderly and disabled in their homes.
