This microrobot is a novel design of needle motion powered by an electromagnetic actuator. The robot has been built by a rapid prototiping machine and permanent magnets.

By using the magnetic field the robotic bug can wriggle forwards backward into a size tube of 12 mm. The principal is to create a drug delivery system device that can be able to go throw to digestion system and/or even carry small loads of medicine or tiny camera.
