Abstract
Force control system. The system includes a first pair of permanent magnets for providing a normal force on the wheel of a robot adapted for n-pipe inspections. A second pair of magnets is provided with opposite polarity so that a rotor containing magnets may be rotated with a minimum of torque required and therefore with a minimum of energy expended.
