Hi, This robot is a six wheeled explorer robot. It has 4 solar panels two of them are 6 V 500 mA and the others 6V 250 mA. In addition to autonomous operation, it can also be controlled by RF remote control. It has 3 obstacle detecting sensors and a RF camera. The camera is placed on a mini servo motor so it can moved. Each wheel has its own dc motor. I have used strings for the parts that connect the motors to the robot's platform for its shock absorber system.
