In the latest episode of the Robots podcast Nikolaus Correll, post doc at the MIT CSAIL's Distributed Robotics Lab, shares his insights on multi-robot systems. He describes his previous work on inspecting a model jet engine for damage using sugar-cube sized robots, and discusses typical trade-offs between reactive robot control and planning, as well as the impact of robot collaboration on performance. His latest work includes a robotic garden and a fascinating project to herd cows using virtual fences. In the second part of this episode we talk to Roderich Gross, currently a postdoc at the EPFL. He introduces the swarm-bots and his work on robot cooperation, self-assembly and division of labour. Tune in!
