CONTROL OF THE OMNI-DIRECTIONAL POWER-ASSISTED CART

Abstract

We developed an easy-to-operate, heavy duty cart comprising a power assist technology available for both longitudinal and rotational motions of the cart. The omni-directional, motor-assisted traveling mechanism uses universal wheels that provide a smooth operation of the cart. This paper describes the system configuration and power assist technology that we have applied, and some of the challenges that we addressed during the development of this new power-assisted cart.
