A challenge for assisting young developmentally-delayed children in learning to walk is to (1) stabilize medio-lateral body sway while promoting opportunities for exploratory behavior, and (2) develop gait that exploits exchange of potential and kinetic energy. To meet the challenge, we have built a modular multi-robot CPS: a scaffold that applies forces at the pelvis via cables to modulate and stabilize center of mass behavior, and a wearable robot that applies assistive torques at the hip.

This project is a modular, computationally‐distributed multi‐robot cyberphysical system (CPS) for assisting young developmentally‐delayed children in learning to walk. Three challenges are stabilizing medio‐lateral body sway, developing gait that exploits energy exchange, and coordination of multiple degrees of freedom. Adults assisting children learning to walk provide a “scaffold” of postural supports that enables the child to safely explore the forces acting on its body.
