Scarab is a 2010 robotic lunar rover prototype designed to assist astronauts take rock and mineral samples.[1] [2] Scarab is capable of autonomously traversing in dark polar craters using laser mapping to navigate and carries a science payload. The science payload is capable of taking a core sample from 1 m depth and analyzing it for water and gasses, and also has an 80 cm bucket wheel for collecting lunar samples. The rover has a mass of 312 kg. [3] Scarab will also be used to test varying mobility techniques and lunar wheels. It is being developed by the Robotics Institute of Carnegie Mellon University, with support by NASA.
