A bi-directional autonomous truck. The truck includes a drive-train
including one or more drive wheels, the drive-train having drive
characteristics that are substantially the same whether the drive wheels
rotate clockwise or counterclockwise. The drive characteristics may
consist of the ability to reach a maximum rotational speed of the drive
wheels, but may include other characteristics, such as the ability to
steer corresponding pairs of drive wheels that are situated at opposite
ends of the truck. Preferably, the truck includes a dump bed that is
adapted for dumping in either of two opposite directions.
