Abstract
Optical trapping of micron to sub-micron sized particles has enabled significant advancements in science and engineering. For spherical particles, the use of dynamic modelbased feedback control has resulted in increasingly fine control over particle position and in turn new scientific discoveries. Extending the success of dynamic control to the case of particles of arbitrary shape is difficult as the complex interactions between the particle and laser light do not lend themselves well to dynamic models suitable for real-time use. In this article a learning-based, model-free control approach for the automated manipulation of non-spherical particles is introduced. This approach is instantiated with the automatic out-of-plane rotation of a sub-micron cylinder in dynamic simulation using visual position and orientation feedback.
