Dynamical system approach for obstacle avoidance in a Smart Walker device

The need for Smart Walkers to help navigation of elderly is increasing rapidly. This paper proposes an approach based on the Dynamical System Approach for obstacle avoidance of a Smart Walker device. Layers of sonars are distributed on the walker for detecting obstacles and stairs. A simulated model of the ASBGo Walker [1] and several realistic simulations in a hospital environment with typical hospital obstacles illustrate the good performance of the approach.
