A vehicle (10), in this embodiment in the form of a mining robot, includes a body (12) and drive rollers (29) at distal ends of telescopic limbs (24, 26) supporting the robot on a support surface at an underside of the body (12). Similar rollers (29) at distal ends of further limbs (20, 22), extend on an opposed side of the body (12) to an opposed surface opposed to the support surface, and engage and brace the robot against the opposed surface. The rollers (29) are power driven to propel the robot along a passage between the surface, such as in a mine tunnel. The robot is braced, and is independent of gravity for stability. The robot can be a platform for tools to perform a task. The limbs (20, 22) can pivot to the same side as the limbs (24, 26) to assist in supporting the robot on a decumbent support surface. |
