The U3-X is a compact mobility prototype on which a person simply sits. Using a proprietary balance system developed by Honda, it provides free movement in all directions just as in human walking – forward, backward, side-to-side, and diagonally. It is possible to control speed, move in all directions, turn and stop by the rider leaning to shift bodyweight.
Honda’s Stride Management Assist device is designed to help those with weakened leg muscles but who are still able to walk. A motor helps lift each leg at the thigh as it moves forward and backward. This lengthens the user’s stride, making it easier to cover longer distances at a greater speed.
Honda’s second experimental walking assist device helps support bodyweight to reduce the load on the user’s legs while walking, going up and down stairs, and in a semi-crouched position. This could lead to reduced fatigue and less physical exertion.
