Robot track timing belt is a loop of flexible rubber material used to mechanically link two or more rotating shafts,
most often parallel. Belts may be used as a source of motion, to transmit power efficiently, or to track relative movement.
Belts are looped over pulleys. In a two pulley system, the belt can either drive the pulleys in the same direction,
or the belt may be crossed, so that the direction of the shafts is opposite.
