Animal-inspired robot transforms to roll, crawl, walk and fly across terrain

A robot inspired by animals can transform its wheels into propellers and hands, which allows it to crawl, roll, and even fly. It could be used to help deliver packages in remote locations and potentially revolutionise space exploration. The Multi-Modal Mobility Morphobot, or M4 for short, has four appendages that can turn into wheels, thrusters, legs and hands.
