A gold/nickel microrobot of 300x300x70 micrometer (10^-6 m) dashing through a maze of photoresist walls.
The robot is controlled by visual servoing, i.e. the user clicks a spot and the computer steers it there.

The robot and required system was built by a team of researches at ETH Zurich (Swiss Federal Institute of Technology) and won the RoboCup in the Nanogram League 2007.
