Abstract:
As humanity returns to the Moon and is developing outposts and related infrastructure, we need to understand how robots and work machines will behave in this harsh environment. It is challenging to find representative testing environments on Earth for Lunar and planetary rovers. To investigate the effects of reduced-gravity on interactions with granular terrains, parabolic flights subject not just the robot but also the soil grains to effectively reduced-g; this technique has enabled us to study the reductions in traction and the increases in sinkage and associated soil mobilization experienced in Lunar-g. Field testing rovers is another essential method for planning future Lunar operations. Our theoretical work in optimal control, and associated experiments in a planetary analogue terrain, have led to skid-steer rover trajectories that can be 10%-20% more energy-efficient than point-turn / straight-line paths.
