4 Wheel rover
thingiverse
My 4x4 Rover is still on the drawing board. I haven't started building or printing this project yet. My plan is to use N20 motors that can be purchased on eBay for the propulsion system. Four 9g servos will handle the wheel control. An Arduino or Raspberry Pi will drive both the servos and the motors. The L298 DC motor driver, or a similar model, will power everything. To ensure a symmetrical design, the arm holding the servos must be mirrored on the other side of the rover.
