RoverX - A lunar rover study

Travels on the lunar surface

This is a lunar rover study I am doing for the Google Lunar X Prize. RoverX is a so called wheg robot. I was inspired by the work of the Case Biorobotics Lab. I started with some sketchup drafts before I built the robot, using 2mm and 1.5mm aluminum sheet.

The wheel legs are from VEX. I've added 6mm wheel hubs to connect the wheels with the 4 gearde motors (cytron-12v-12rpm-166oz-in-spur-gearmotor).The motor driver is a Sabertooth 2x25, controlled by simplified serial.

The main board and the robot arm control board:

The PIC12F683 monitors the voltages of the two Li-Po batteries. If the voltages drop under a certain limit, a buzzer starts to sound:

Remote control, using cheap 433 MHz transmitter module:

RoverX with LADAR:

Useful sketch for programming the arm:

I have created a poll: Which Google Lunar X Prize team has the most sophisticated rover in the moment?

You're all roboteers, be honest, visit the team web sites, study the rover prototypes and vote then:)

The algorithm can include that the calculation will be repeated only one or two or three times.

Which controller is now defect? I am thinking on a simple mechanism they are using in manned spaceships. The astronaut can activate manual control over the ship but must plug in a secret code firstly. This asures that only a clear thinking astronaut can overtake the space ship.

Most big electroncis companies offer space qualified components, also micro controller. Sure, as the circuit would be simple, it could be made by discrete components.
