Development of the Tri-ATHLETE Lunar Vehicle Prototype

摘要

The Tri-ATHLETE (All Terrain Hex Limed Extra Terrestrial Explorer) vehicle is the generation of a wheel-on-limb vehicle being developed to support the return of humans to the lunar surface. This paper describes the design, assembly, and test of the Tri-ATHLETE robotic system with a specific emphasis on the limb joint actuators. The design and implementation of the structural components is discussed, and a novel and low cost approach to approximating flight-like cabling is also presented. The paper concludes with a discussion of the second system effect and other lessons learned as well as results from a three week long field trial of the vehicle in the Arizona desert.
