While investigating why Cave Rover had a lean on the right tread in photos, turns out poor little robot had a broken metal shaft bushing. My guess has be there since the mishap when squished to half its height under 120lbs Big Rover, during an accident filming the Big Foot video months ago. I leave Rover looking like a bit of a misfit, grown rather attached to it that way, but put in effort to keep it working top notch, as it still functions, out side of entertaining, as the primary system, software and sensor test and development bot. Luckily was able to salvage a replacement from a broken motor. Cave Rover is sitting tall and toned again.
