AGRO (Agile Ground RObot) is a robotic car that lands on all four wheels falling from various heights. Usually, robotic cars that fall from heights will lack performance in a few areas, being complexity, mobility, or mass. AGRO is changing the standard by using unique wheels to stabilize itself independently.
AGRO uses four steerable wheels with in-hub motors to control all three axes (yaw, pitch, and roll). This allows the robot to maneuver the body of the car in the opposite direction of the wheels. The robot uses a significant amount of mid-air control to adjust and stick the landing.
"Given enough height, the current generation of AGRO can recover from any initial orientation as long as it's spinning at 66 rpm or less," says Christopher Korpela from The Robotics Research Center at West Point.
Robots like these can help search and rescue teams and even change how robots are dropped from aircraft.
