<p>A tracked vehicle of narrow aspect suitable for unmanned operation both in hazardous environments and on routes normally accessible only to pedestrians, comprises two identical vehicle units (1, 2) each having an independently drivable, full width track (3), the units being interconnected in tandem configuration by an articulation mechanism (9) permitting relative rotation about a yaw axis (Y). In one aspect the articulation mechanism is passive, being arranged with an offset yaw axis, thereby permitting steering by application of a velocity differential to the two tracks. In a second aspect the articulation mechanism is active being powered by an actuator (94) to provide articulation steering. The articulated units may also be secured in parallel configuration for conventional skid-steering operation.</p> |
