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.
