I suspect he just means a robot with separate controls for the left and right wheels. For RobotWars use people generally use a radio control with a "V-tail" mixer to convert forwards/backwards/steer into separate left-right mixing. I suspect that the aim here is to do something on-board. Incidentally, one of the UK robotwars robots used a different system, a differential with a motor in it (powered through slip-rings) that overlaid a steering input onto the main forwards-backwards. They seemed unimpressed when I pointed out that that was a daft way of doing it (driving one half-shaft and reversing the other with a static motor driving the prop-shaft for steering would have been simpler) -- atp ------------------------------------------------------------------------------ Let Crystal Reports handle the reporting - Free Crystal Reports 2008 30-Day trial.
