Abstract
A driverless tugger vehicle is adapted to shuttle back and forth and push or pull another driverless vehicle each time it moves in a forward direction. The tugger vehicle is propelled by frictional contact between a drive wheel and a drive shaft with the drive wheel being mounted for pivotable movement through an arc of approximately 90 degrees so that the vehicle may reciprocate in opposite directions without changing the direction of rotation of the drive shaft.
