Abstract
A controllable mobile apparatus travels along a commanded path under the control under a navigation system that provides speed and direction commands to navigate the controllable mobile apparatus. The controllable mobile apparatus has a plurality of wheels which are driven by servo control systems in response to speed commands that are provided by the navigation system. The trajectory of the mobile apparatus is also controlled by the navigation system, and it includes a servo system that is, in the illustrated embodiment, the same as the servo system used for controlling the speed of the mobile apparatus. Additionally, there is implemented a software filter system which filters the speed and direction commands.
