Cost: ~$1000.00
Time to Build: 6 Months * 4

The MJ12-SRRV was designed and built to satisfy a Design course for a final year project in college.

The bot is essentially a really fancy RC car with a wireless camera and a 3-axis arm on top. The project was broken into 4 sections:
the Basestation, the Rover/Arm controller, the wireless communication and the motor controller

All circuit boards were built and etched by hand.
