Brute Frorce Digger 4

After the second Regolith Challenge, rule changes (primarily the change from 150 watts to unlimited on-board battery supplied power) reduced the competitive value of  BFD 3 which was designed around the 150 watt requirement. Brute Force was designed around a 900 watt rotary cutter with heritage back to our original BFD 1 design. The cutter was extraordinarily innovative in that it could cut efficiently in either direction. In addition, the mass conveyor went through the center of the cutter.

 

The onmi-directional drive wheels are sealed and powered from inside. The “ski lift” conveyor system allowed both horizontal and vertical mass transfer with near zero transition length.

This is how it came out ... love that CAD!
