For sending images back to Earth, the robot is equipped with a 353 high-definition camera manufactured by Elphel, one of the companies sponsoring the project. The group is working on developing antennas for sending the images captured with the camera back to Earth. The ESPC group has developed several prototypes of the PicoRover with the goal of developing a fully autonomous robot capable of moving or stopping as required on the lunar surface. The prototype on which the group is currently working is a ball measuring 12cm in diameter that houses a motor, battery, remote control system and a high-definition camera. The entire device weighs less than 250g and, like most school projects, the ball is built from low-cost, common-use materials such as light bulbs, aluminum foil, and steel wire. However, the ball is capable of protecting its inner components from the high lunar temperatures and of climbing up sandy slopes at angles of up to 30° – a feat that can tax wheeled vehicles.
