TOKYO--(BUSINESS WIRE)--Honda Motor Co., Ltd. today unveiled its second experimental walking assist device that helps support bodyweight to reduce the load on an individual’s legs while walking, going up and down stairs, and in a semi-crouching position. The device is designed for people who are capable of walking and maneuvering on their own, but who can benefit from additional leg and body support while performing tasks. Honda will now begin testing the device in real-world conditions to evaluate its effectiveness.
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 individual can put it on by simply wearing 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 on a walking assist device in 1999 with the goal to provide more people with the joy of mobility. The first walking assist device, announced in April 2008, has a stride management system and was designed for people with weakened leg muscles, due to reasons such as aging. The research and development of Honda’s advanced humanoid robot, ASIMO, including the study of human walking, provided Honda with the knowledge necessary to develop the walking assist device. 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.
