World’s smallest morphing robot takes on land, air for future rescue missions

Researchers from Chinese universities have developed a 9 cm-long, 25-gram shape-shifting robot capable of flying and ground movement. Using heat-reactive polymer actuators, the device can change shape to adapt to different environments. In tests, it flew over obstacles, landed, and transformed to drive on the ground. This technology could revolutionize search and rescue, medical devices, and virtual reality systems, making it ideal for disaster relief and environmental monitoring.
