RodBot: A rolling microrobot for micromanipulation [PDF]

2015 IEEE International Conference on Robotics and Automation (ICRA), 2015
We introduce the modelling and control of a rolling microrobot. The microrobot is capable of manipulating micro-objects through the use of a magnetic visual control system. This system consists of a rod-shaped microrobot, a magnetic actuation system and a visual control system.
