This is the Multi-Modal Mobility Morphobot M4 robot: a bio-inspired robot that transforms to crawl, roll, and fly. Inspired by nature, this robot has limb-like rotors and wheels to move in a variety of ways and save energy. It can handle slopes up to 45 degrees. It can also overcome rough terrains in balancing mode.
The M4 has onboard computers and sensors and can autonomously choose a mode to adapt to an unstructured environment. The above video shows it in action.
