HONDA ASIMO WALKING ASSISTANCE
Honda is well known for its cars and motorcycles. What is less known is its research in robotics technology, as seen in the Honda ASIMO robot. Since the company is capable of making ASIMO walk “reliably” on its own, why not extend the technology to help humans in walking?
And thus, Honda’s new Walking Assist Device is born. Available in three sizes, the device is worn around the hips and thighs to assist walking for the elderly and other people with weakened leg muscles. Unfortunately, it is designed to assist only people who can already walk on their own.
It uses brushless DC motors powered by lithium ion batteries, allowing up to two hours of walking assistance per battery charge.

Honda to Showcase Experimental Walking Assist Device at BARRIER FREE 2008
TOKYO, Japan, April 22, 2008– Honda Motor Co., Ltd. will showcase an experimental model of a walking assist device which could support walking for the elderly and other people with weakened leg muscles(*), at the International Trade Fair on Barrier Free Equipments & Rehabilitation for the Elderly & the Disabled (BARRIER FREE 2008) which will be held at Intex Osaka, Friday, April 25 through Sunday, April 27, 2008 (Organizers: Osaka Prefecture Council of Social Welfare and Television Osaka Inc.)
Honda began research of a walking assist device in 1999 with a goal to provide more people with the joy of mobility. Currently, the device has entered into the feasibility stage.
The cooperative control technology utilized for this device is a unique Honda innovation achieved through the cumulative study of human walking just as the research and development of technologies was conducted for Honda’s advanced humanoid robot, ASIMO. Applying cooperative 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 fit to different body shapes.
The research of this device is being conducted by the Fundamental Technology Research Center of Honda R&D Co., Ltd. in Wako, Saitama.
Honda is planning to offer interested attendees an opportunity to wear and experience this walking assist device at the Honda booth at BARRIER FREE 2008.
(*) This device is designed for people who are still capable of walking on their own.
