Claim:
1. A motorized truck with tiller comprising: (a) a chassis having a plurality of ground-engaging wheels, at least one of which is steerable to steer the truck; (b) a drive motor for driving at least one of the wheels to move the truck across the ground; (c) a tiller rotatably connected to the chassis which may be swung from side to side to steer the truck; (d) a steering motor for varying the angle of the steerable wheel; (e) a steering motor controller which, in a normal mode of operation, receives as an input an indication of the tiller angle and which outputs in response thereto a control signal to the steering motor to vary the angle of the steerable wheel such that the angle between the tiller and steerable wheel maintains a predetermined angular offset; wherein the angular offset between the tiller and steerable wheel may be adjusted and the adjusted angular offset is subsequently used as the predetermined angular offset; and wherein said adjustment of the angular offset is carried out by said steering motor controller in a realignment mode of operation, in which the steering motor controller outputs a control signal to the steering motor to steer the wheel to a different angular offset.
