RRB-107 is an acronym that stands for Robotic Rover Booster, a wheeled robotic vehicle used to support scientific exploration of extreme terrain. It was developed by SEISU Robotics in the late 1990s for NASA's Jet Propulsion Laboratory (JPL). The rover was designed for extreme terrain exploration by combining wheeled and tracked drive systems, a long wheelbase, high ground clearance, and a wide wheel track. It was equipped with six wheels and two tracks, allowing RRB-107 to climb over rock fields and traverse gullies and ditches with ease. RRB-107 is capable of autonomous navigation, using a host of sensors and instruments to measure the terrain and climate in which it is operating. Additionally, it carries a suite of cameras, which provide the visual data needed to operate the vehicle and map the environment.
