Abstract: A robot has an electronic surveillance system embedded within a chassis disposed between two wheels. The wheels include a main body and a plurality of treads. The treads are generally disposed radially around the main body and extend distally from outer portion of the main body. The main body generally defines a plurality of compression cells and may present a substantially frustoconical outer surface.

Abstract: A two wheeled throwable robot with a pair of motorized wheels mounted on each end of an elongate body and a rearwardly extending tail. The body comprising a chassis with an accessory mounting interface on top side and rearward side. A backpack accessory providing active sensing or environmental effects has an inverted L-shape when viewed from an end and attaches to the rearward side of the elongate body and extends over the topside of the body. The stabilizing tail for the two wheeled robot attaches to a rearward surface of the backpack accessory. The robot and backpack accessory have impact protection means when the robot is thrown. The backpack accessory may be within a zone of protection defined by the maximum deflection of the wheels or may have elastomeric bumpers when the accessory backpack projects out of the zone of protection.

Abstract: A two wheeled robot with a pair of motorized wheels mounted on each end of a body and a rearwardly extending tail. The body comprising a chassis with sides and exterior side surfaces and providing an accessory mounting interface. The interface having a matrixical arrangement of threaded holes and one or more landings, the landings having an outwardly facing planar landing surface with hole openings at the landing surface. An accessory with a robot mounting interface cooperates with the chassis at the accessory mounting interface such that prior to fastening the accessory has a single degree of freedom of movement. Screws extend through portions of the accessory into select ones of the threaded holes of the matrixical arrangement.

Abstract: 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.
