Two identical RnR Products APV-3 aircraft validated cooperative flight control software in the Networked UAV Teaming Experiment at NASA Dryden in early 2005.

Members of NASA's CADRE (Cooperative Autonomous Distributed Robotic Exploration) technology demonstration team pose with two full-scale development model rovers in the Mars Yard at the agency's Jet Propulsion Laboratory in Southern California in January 2024. The project is designed to show that a group of robotic spacecraft can work together as a team to accomplish tasks and record data autonomously – without explicit commands from mission controllers on Earth. Three small rovers will ride aboard a lunar lander that will carry the project's base station and camera assembly. The rovers shown here are similar in size and appearance to the flight models that will travel to the Moon. Equipped with flight software and autonomy capabilities, these development models were used in a series of Mars Yard tests that helped confirm CADRE hardware and software can work together to accomplish key goals for the project. https://photojournal.jpl.nasa.gov/catalog/PIA26170

A development rover that is part of NASA's CADRE (Cooperative Autonomous Distributed Robotic Exploration) technology demonstration drives over a rock during its first autonomous drive around the Mars Yard at the agency's Jet Propulsion Laboratory in Southern California in June 2023. Under a canopy behind the rover are, from left, graduate student intern Natalie Deo and CADRE verification and validation lead Sawyer Brooks of JPL. The CADRE team successfully tested a new wheel design, surface navigation software, and mobility capabilities, among other aspects of the project. The rover being tested is similar in size and appearance to the flight models of the CADRE rovers, which are still being built. Slated to arrive at the Moon in spring 2024 as part of NASA's CLPS (Commercial Lunar Payload Services) initiative, CADRE is designed to demonstrate that multiple robots can cooperate and explore together autonomously – without direct input from human mission controllers. A trio of the miniature solar-powered rovers, each about the size of a carry-on suitcase, will explore the Moon as a team, communicating via radio with each other and a base station aboard a lunar lander. By taking simultaneous measurements from multiple locations, CADRE will also demonstrate how multirobot missions can record data impossible for a single robot to achieve – a tantalizing prospect for future missions.

A development model rover that is part of NASA's CADRE (Cooperative Autonomous Distributed Robotic Exploration) technology demonstration took its first autonomous drive around the Mars Yard at the agency's Jet Propulsion Laboratory in Southern California in June 2023. The CADRE team tested a new wheel design, surface navigation software, and mobility capabilities, among other aspects of the project. Engineer Kristopher Sherrill is shown recording video of the test. The rover being tested is similar in size and appearance to the flight models of the CADRE rovers, which are still being built.

Two full-scale development model rovers that are part of NASA's CADRE (Cooperative Autonomous Distributed Robotic Exploration) technology demonstration drive in the Mars Yard at the agency's Jet Propulsion Laboratory in Southern California in August 2023. The project is designed to show that a group of robotic spacecraft can work together as a team to accomplish tasks and record data autonomously – without explicit commands from mission controllers on Earth. The rovers being tested here are similar in size and appearance to the flight models – still being built at the time of this image – that will travel to the Moon. Equipped with flight software and autonomy capabilities, these development models were used for drive tests outside the clean room. In this image, one rover is fitted with a stand-in for solar panels, while the other rover is not. A series of Mars Yard tests with the development models confirmed CADRE hardware and software can work together to accomplish key goals for the project. The rovers drove together in formation. Faced with unexpected obstacles in the way, they adjusted their plans as a group by sharing updated maps and replanning coordinated paths. And when one rover was low on battery charge, the whole team paused so they could later continue together. Several drives were performed at night under large flood lamps so the rovers could experience extreme shadows and lighting that approximate what they'll encounter during the lunar daytime. https://photojournal.jpl.nasa.gov/catalog/PIA26168
