Honda unveils experimental walking assist device with bodyweight support system

07 November 2008

Honda Motor Co., Ltd. unveiled its second experimental walking assist device that helps support bodyweight to reduce the load on the user's legs while walking, going up and down stairs, and in a semi-crouching position. Honda will now begin testing the device in real-world conditions to evaluate its effectiveness. This device is designed for people who are still capable of walking on their own.

The new walking assist device with the bodyweight support system reduces the load on leg muscles and joints (in the hip, knees, and ankles) by supporting a portion of the person's bodyweight. The device has a simple structure consisting of seat, frame, and shoes, and the user can put it on by simply wearing the shoes and lifting the seat into position.

Moreover, a mechanism that directs the assisting force toward the user's center of gravity and the ability to control the assist force in concert with the movement of the legs - both unique Honda innovations - make it possible for the device to provide natural assistance in various postures and motions.

Honda began research of a walking assist device in 1999 with the goal to provide more people with the joy of mobility. Honda developed the knowledge required to develop the walking assist device from its thorough study of human walking represented by the research and development of Honda's advanced humanoid robot, ASIMO.

This research has been conducted by the Fundamental Technology Research Center of Honda R&D Co., Ltd. in Wako, Saitama. To evaluate the effectiveness of the experimental model of the walking assist device with bodyweight support system, Honda will test the walking assist device at its Saitama Factory (in Sayama, Saitama) starting this month.
