MAGNETIC LOCK WITH THROWABLE ROBOT

A two wheeled throwable robot comprises an elongate chassis with two ends, a motor at each end, drive wheels connected to the motors, and a tail extending from the elongate chassis. The throwable robot includes an enable/disable arrangement comprising a pair of magnets generating a magnetic field and a magnetic field sensor positioned in proximity to the pair of magnets. The sensor is activated upon the occurrence of a specific modification of the magnetic field. The throwable robot may include a key member formed of a material to modify the magnetic field to enable the robot.
