In this paper we present a system that could be used to help people with walking disabilities. A system consists of a prototype mobile robot platform equipped with a control board and a remote computer system, running with image processing algorithms, was used to develop a system for physically disabled human to move freely in an environment. We used a camera to get visual information by a huma...
