Primary challenges in the building of untethered sub-millimeter sized robots include power supply, propulsion methods, and control. Presented in this video is a microrobot called Magmite that uses a new class of wireless magnetic actuator to master all three design challenges. The device harvests magnetic energy from the environment and effectively transforms it into mechanical propulsion while being fully controllable. This microrobotic agent with dimensions less than 300 mum times 300 mum times 70 mum is capable of maneuvering with 3 degrees of freedom.
