Previous space exploration missions used a single robot to collect data from extraplanetary surfaces. However, the implementation of multi-robot systems is advantageous because smaller rovers can cover more ground, are more agile, and can access unexplored regions of space. In a partnership with NASA Jet Propulsion Lab, the Stanford Navigation and Autonomous Vehicles (NAV) Lab is developing navigation algorithms for multi-robot systems that will be used in future extraplanetary exploration missions. An example of one of these multi-robot systems is CADRE (Cooperative Autonomous Distributed Robotic Explorers). CADRE uses shoe-box-sized rovers that will autonomously expand the frontier of the explorable lunar surface. This research quantifies error and reliability of Ultra-Widebands ranging radios for use with multi-robot navigation and evaluates methods for error correction. The “Sensor Characterization of Ranging Radio for Extraplanetary Exploration” project is a series of tests that follow the development of navigation algorithms for lunar rovers. In previous space exploration rover missions, one robot was sent to explore. However, sending multiple robots that contact each other is more efficient because we can collect data from dangerous unexplored areas as long as the robots share information. With that being said, NASA is currently working on sending small rovers that collaborate autonomously to explore extraterrestrial surfaces.
