Those who have difficulties in walking may not be bound to a Segway for life, thanks to Honda. The Japanese automaker is developing a new technology called the experimental walking assist device. These accessory legs have been designed as a means to offer a helping, um... leg to those who have problems supporting themselves in day-to-day life, but are capable of walking without assistance.

 

According to Honda, these experimental robotic legs can help support body weight, mainly for people carrying heavy loads or who are stuck in a crouching position. This way, they act more like a mobile chair than some sort of exoskeleton. 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 certain tasks.

 

Reducing the load on leg muscles and joints (in the hips, knees and ankles), by supporting a portion of the person's body weight, the device's structure consists of seat, frame and shoes, with the individual being able to 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.

 

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 embedded in the shoes of the device.

 

Weighing 6.5 kilograms (including shoes and batteries), the experimental walking assist device with body weight support system features 2 motors and a Lithium-Ion battery, which provides 2 hours of operation per charge.
