Drone can transform into a tiny car to slide under small gaps

New Scientist 

A shape-shifting drone can transform into a car once it touches down. The drone, called FSTAR, can move through a variety of surfaces and environments, making it a potentially helpful tool in search and rescue missions. FSTAR has a wheel and a propeller on each of its four legs. The prototype is about 35 centimeters long and 25 centimeters wide. During operation, a human pilot uses a controller to drive FSTAR and change its configurations.
