A DESIGN METHOD VIA MODULARIZATION FOR CONTROLLERS OF MOBILE ROBOTS HAN Da-peng WEI Qing (Dept. of Mechtronic Engineering and Automation, National University of Defense Technology, ChangSha 410073, China) Abstract:In this paper, based on CAN bus, a new kind of controller for ground-moving robots is present, whose structure is obtained via modularization. This design, which is reliable and expansible, has been proved to be practicable through applications. Key words: modularization; robot controller; CAN bus
