Ideally, a body surrogate robot could support a quadriplegic when human caregivers are not around. Most robots have a safety device called a run-stop – a big red button that can be pressed if the robot runs amok or starts behaving erratically. But a quadriplegic can’t press the big red button, so how can he safely use a robot when it’s most needed? What is needed is a hands-free run-stop.
Charlie Kemp came up with an approach to this problem called the WOUSE, and Henry Clever implemented the prototype shown here.
