Many videos have been posted of weighted robots towing trailers on regolith using skid steer without trouble. The coefficients of friction in the manual may not be entirely correct.

Another problem with many of those suggestions is that the require ground-level motors and linkages, which take up room that could be used for a ball picker-upper. I don't know about you, but I'm of the belief that human-only-loaded robots will be at a disadvantage this year, in contrast to 2006.

Cool ideas, though. I might bookmark this page for ideas in future years.
