![]() The second generation ATHLETE prototype was constructed in 2009 and is implemented as a coordinated system of two Tri-ATHLETEs, fully independent three-limbed robots. ![]() Two identical prototypes were constructed in 2005 and one of these is still operational. The first generation ATHLETE prototype is 2.75m wide, has a maximum standing height of just over 2m, a mass of approximately 850 kg, and maximum payload carrying capacity of 300 kg in Earth gravity. ![]() To demonstrate this concept, several prototype vehicles have been developed for testing at JPL. ATHLETE is envisioned as a heavy-lift utility vehicle to support human exploration of the lunar surface, useful for unloading bulky cargo from stationary landers and transporting it long distances. In the latter case, wheels can be locked and used as feet to walk out of excessively soft, obstacle laden, steep, or otherwise extreme terrain. ATHLETE uses its wheels for efficient driving over stable, gently rolling terrain, but each limb can also be used as a general purpose leg. The All-Terrain Hex-Limbed Extra-Terrestrial Explorer (ATHLETE) vehicle concept is based on six 6 DoF (Degrees-of-Freedom) limbs, each with a 1 DoF wheel attached. 1: 2nd generation ATHLETE unloading cargo ![]()
