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. |
