This is a wonderful effort to crowd source new ideas. Led by the Toyota Mobility Foundation.
This particular effort applies only to lower-limb paralysis but fear not. There are always knock-on effects and mny of the grants already made actually address needs of the more seriously impaired.
"Already, the challenge is leading to some unique ideas. On April 11, Toyota Mobility Foundation announced the winners of the Discovery Awards — $50,000 given to 10 teams to help enter the challenge. Among those receiving the awards were semi-autonomous gaze-based drive system for power wheelchairs, a self-balancing manual wheelchair designed to eliminate constant ground contact with the front casters, next-gen e-powered rear wheels for a manual wheelchair, a variety of new exoskeletons and even a hover board that can accommodate a manual wheelchair."
