A robotic vehicle (A,BC,A,B,C) includes a chassis () having front and rear ends (A,A,B,B) and supported on right and left driven tracks (). Right and left elongated flippers () are disposed on corresponding sides of the chassis and operable to pivot. A linkage () connects a payload deck assembly (D,D,D), configured to support a removable functional payload, to the chassis. The linkage has a first end (A) rotatably connected to the chassis at a first pivot (), and a second end (B) rotatably connected to the deck at a second pivot (). Both of the first and second pivots include independently controllable pivot drivers () operable to rotatably position their corresponding pivots () to control both fore-aft position and pitch orientation of the payload deck (D,D,D) with respect to the chassis ().

A robotic vehicle includes a chassis supported on right and left driven tracks, right and left elongated flippers disposed on corresponding sides of the chassis, and a battery unit holder disposed on the chassis for removably receiving a battery unit weighing at least 50 lbs. The battery unit holder includes a guide for receiving and guiding the battery unit to a connected position and a connector mount having locating features and communication features. The locating features receive corresponding locating features of the battery unit, as the battery unit is moved to its connected position, to align the communication features of the connector mount with corresponding communication features of the battery unit. The communication features of the connector mount are movable in a plane transverse to the guide to aid alignment of the communication features for establishment of an electrical connection therebetween when the battery unit is in its connected position.

A robotic vehicle is disclosed, which is characterized by high mobility, adaptability, and the capability of being remotely controlled in hazardous environments. The robotic vehicle includes a chassis having front and rear ends and supported on right and left driven tracks. Right and left elongated flippers are disposed on corresponding sides of the chassis and operable to pivot. A linkage connects a payload deck, configured to support a removable functional payload, to the chassis. The linkage has a first end rotatably connected to the chassis at a first pivot, and a second end rotatably connected to the deck at a second pivot. Both of the first and second pivots include independently controllable pivot drivers operable to rotatably position their corresponding pivots to control both fore-aft position and pitch orientation of the payload deck with respect to the chassis.

A mobile robot includes a chassis defining at least one chassis volume and first and second sets of right and left driven flippers associated with the chassis. Each flipper has a drive wheel and defines a flipper volume adjacent to the drive wheel. The first set of flippers is disposed between the second set of flippers and the chassis. Motive power elements are distributed among the chassis volume and the flipper volumes. The motive power elements include a battery assembly, a main drive motor assembly, and a load shifting motor assembly.

A method is disclosed for a robotic vehicle to climb a step. The robotic vehicle uses tracked flippers to engage the top of the step and drives with additional tracks other than the tracked flippers. The robotic vehicle also shifts and tilts a payload in order to move the CG of the payload ahead of the vehicle chassis and past the edge of the step.
