Perseverance AutoNav Avoids a Boulder

This animation is a playback of data recorded by NASA’s Perseverance Mars rover during an autonomous drive on July 15, 2023, the 854th day, or sol, of the mission. During this drive, the rover identified and navigated around the 14-inch (35-centimeter) rock seen at center-left. The self-driving autonomous navigation system, AutoNav, allows the rover to autonomously re-plan its route around rocks or other obstacles on its way to a pre-established destination. Engineers driving the rover at NASA’s Jet Propulsion Laboratory in Southern California use visualization software to plan how the rover moves around on Mars and to evaluate its performance. The lines seen emanating from the front of the rover are 20 feet (6 meters) long and indicate the paths the rover is evaluating for safety in real time, while driving. Lines that turn blue show where the rover identified a “wheel drop” hazard – where a wheel could drop more than 14 inches (35 centimeters). Magenta lines indicate where the rover saw a belly pan
