1. A robotic vehicle comprising:

  • a chassis having front and rear ends and supported on right and left driven tracks, each track trained about a corresponding front wheel rotatable about a front wheel axis;

    right and left elongated flippers disposed on corresponding sides of the chassis and operable to pivot about the front wheel axis of the chassis, each flipper having a driven track about its perimeter and a flipper end distal from the front wheel axis of the chassis;

    a payload deck assembly configured to support a removable payload; and

    a linkage connecting the payload deck to the chassis, the linkage having 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,wherein the robotic vehicle is configured to pivot the flippers so that, in a first position, the flippers and the chassis are aligned and, in a second position, the flipper ends are rearward of the front end of the chassis so that the flippers and the chassis define an acute angle between a plane extending from the front end of the chassis to the rear end of the chassis and the flippers.
