A Versatile Swarm of Individually Controlled Microparticles for Object Manipulation and Transport — •Veit-Lorenz Heuthe1, Emanuele Panizon2, and Clemens Bechinger11Universität Konstanz, Konstanz, Germany — 2International Centre for Theoretical Physics, Trieste, Italy

Some tasks for robotic systems require many robots to cooperate, similar to ants that join their forces to carry large objects. On a macroscopic scale, many examples for such collective tasks exist, like robot swarms that can assemble objects. However, future potential applications like minimally invasive medicine call for miniaturization of such concepts. On the microscopic scale, one major challenge is the strong thermal noise, that demands for much more robust control. We use a reinforcement learning algorithm to individually steer microswimmers in a swarm that can manipulate and transport a large object. Due to decentralized control, our multi robot system is highly flexible, scalable and robust. With this demonstration we take micro-robot swarms one step further on their way to become tools for manipulating microscopic objects.
