Lightweight Reconnaissance Vehicle (LRV)

ARA engineers have developed the LRV for tele-operated use and it is able to climb and descend stairs, rocks, and rubble up to 11'' in height. This small, agile robot has the ability to operate as a stand-alone robot (man packable), or as a mission module (marsupial).

The LRV uses a polymorphic locomotion system which allows it to operate in a wheeled mode to traverse moderate terrain quickly and a rough terrain mode for efficient maneuvarability over a wide range of environmental conditions such as: steps, rocks, building obstacles, building debris, compound slopes (successfully tested up to 45 degrees), sand, and ice surfaces. The platform has an optional pivoting body capable of moving 30 degrees relative to the other side, allowing great mobility in the wheeled mode.
