We are building a new and improved version of our Mars Rover. Here are a few pics of our work-in-progress.
Camille is constructing one of the six motor-servo assemblies.
The partially finished motor-servo assembly. There will be six of these, one for each wheel. A powerful HS-7950TH Hitec Servo motor is used to rotate the wheel in place. A 60:1 motor is used to drive the wheel.

This is a simple but effective power rail that we made for the Mars Rover. We made this by cutting up a blank circuit board and then soldering 16 screw terminals onto it. One side will be voltage. The other side will be ground. Its purpose is to distribute power from the battery to all the various electronic components.
Here we are drill a 1/2″ hole for the power switch in the back panel of the robot.
Here is the back panel of the Mars Rover’s main box, including the hole for the power switch as well as a cut out for battery compartment, which we cut with a mini mill.
