ESP in the Mojave Desert

Jon and Marlin just returned from a successful field test in the Mojave desert where they were evaluating path planning techniques for complex terrain. They were working with the NASA Jet Propulsion Laboratory (JPL) Robotic Surface Mobility group on the Axel/DuAxel rover platform. You can see photos of everyone's great work here.
