Abstract
A driverless vehicle is provided with support wheels on one side and drive wheels on the opposite side. The drive wheels perform the dual function of supporting one side of the body and propelling the vehicle by frictional contact with a drive shaft. The drive wheels are coupled together for oscillation about a vertical axis and are biased to a drive position. The vehicle body is provided with a cam for causing accumulation upon contact with another vehicle.
