Abstract

A suspension system (10) for a lightweight robotic crawler is disclosed. The Suspension system provides for mounting of a flexible endless track (18) thereon. The suspension system includes a forward guide (14) and a rearward guide (16) around which the endless track can be looped. A deflector (20) positioned between the forward guide and the rearward guide downwardly deflects a ground-engaging portion of the endless track to form a peaked area. The peaked area (24) can support the lightweight robotic vehicle allowing alteration of a distribution of load over the ground- engaging portion of the endless track with respect to a supporting surface.
