Honda Unveils an Experimental Walking Assist with a Bodyweight Support System

Here’s a new experimental walking assist device from Honda, a system that not only helps you walk, but also supports your bodyweight. To put it simply, if you’re unfortunate enough to be unable to walk freely, it will support you. As seen in the video, once in its shoes it almost walks for you.

I was amazed by the changes over their previous version, and also happy to see Honda doing their very best with their Asimo research to help the disabled.

Press release below!

Japan, November 7, 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.

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.
* This device is designed for people who are still capable of walking on their own.

■ Key Features
1. Convenient sitting-type device

· The user simply needs to wear the shoes and raise the seat into place.

· The user can benefit from the assist without need of a belt to fasten the device to their body.

· The structure to position the device between the user’s legs minimizes the required footprint, therefore making it easier for them to maneuver.

2. Method to assist bodyweight support

· The device will support a portion of the person’s bodyweight by lifting the seat as the frame between the shoe and seat bends and extends, just like knees, with the force from the motor. As a result, the load on leg muscles and joints (in the hip, knees, and ankles) is reduced.

· Honda developed a unique mechanism where the seat and frame follow the movement of the body and legs. The assisting force will be directed toward the user’s center of gravity, just as with human legs, which enables the device to provide assistance in various movements and postures including walking, going up and down stairs, and in a semi-crouching position.

3. Natural control of the assisting force

· Natural walking is achieved by changing the amount of assisting force applied to the right and left legs through the control of two motors based on the information obtained though sensors imbedded in the shoes of the device.

· The effectiveness of the device was increased in those motions and postures which put increased load on knees, such as going up and down stairs and in a semi-crouching position. This was achieved by adjusting the assisting force in accordance with the bending and stretching motion of the knees.

    I bet I could hack it for running up stairs superfast and break the record going trough all torii at the Fushimi Inari Shrine.

    My daughter has a problem of stability in walking, this device could help her to walk normally ?

    This is something vaguely similar to something I am working on. This is a very nice design and all, but it is very limited in depth. It really only helps individuals with poor muscular development / control. It has no corrective ability for anything other than typically shaped and oriented legs. (i.e. it will not help an individual with bowed, minorly malformed, or slightly deformed legs.. nor will it really help with gait issues.)

    Like I said, its a nice design all and all.. but it could have been thought out a little bit more than it was. Of course it could be used as a good starting point for other similar projects.

    how much it cost??
    does it functions for invalid people??
    what are the benefits of these???
