Abstract:
The present teachings relate to a small unmanned ground vehicle (100). The present teachings relate more particularly to a small unmanned ground vehicle (100) weighing less than about five pounds, and which is designed to absorb an impact from being dropped or thrown and climb stairs of a conventional size, to perform a variety of behaviors such as stair climbing, self righting, and gap crossing, and to be sealed to prohibit ingress of liquids and debris.

Abstract:
The present invention relates to a tracked mobile robot (100) comprising axles (142, 144), resilient wheels (106, 118, 130, 136), flippers (110) mounted on one of the axles, a front camera (124) and side cameras (114), whereby the flippers comprise apertures configured to substantially align with the side cameras when the flippers are in a position extending between the axles.
Abstract:
Unmanned ground vehicles configured for compact manipulator stowing are disclosed. In some examples, an unmanned ground vehicle includes a main body and a drive system supported by the main body. The drive system includes right and left driven track assemblies mounted on right and left sides of the main body. A manipulator arm is pivotally coupled to the main body and configured to extend from a stowed position to an extended position, and the manipulator arm in the stowed position is contained entirely within a geometric volume of the right and left driven track assemblies.

Abstract:
A robot (100,800,1100,1200,1400,1600,2200,2300,2400,2500,2600,3300) includes a chassis (140,301,310,501,801,1601,3202) supporting a skid steered drive (110,1610,2202,2204,3310) and a set of driven flippers (130,302,502,602,802,1602). Each flipper is pivotable about a first pivot axis (15,315) common with a drive axis (15) near the chassis's leading end (104A,302A). The robot includes a neck (305,805,1605,2210) pivotable about a second pivot axis (317) substantially at the chassis's leading end (140A,301A) and a sensor head (303,803,1603,2206) pivotally coupled to the neck (305,805,1605,2210). The chassis, flippers, neck and head: (i) have a combined center of gravity (combined-CG,364,CG1,CG50) disposed in a forward-rearward sense between distal and pivot ends (130A,130B,302A,302B) of the flippers (130,302,502,602,802,1602) when the flippers are in a stowed position with their distal ends (130A,302A) between leading and trailing ends (140A,140B,301A,301B) of the chassis, and (ii) are each independently movable between a first position and a second position to reposition the combined center of gravity for negotiating an obstacle.
