Recently we were asked to build a miniature Mars Rover for a new space museum in the Czech Republic. Although the Mini Mars Rover is only about 8″ long, it is a functional robot, including an Arduino Nano microcontroller, a high-resolution wifi camera, an xbee radio for remote control, a Sabertooth motor controller, six motors, a rocker-bogie suspension system, and other components. We designed and machined most of the robot’s parts using our CNC Mill.
