CU-Boulder researchers are working to build a swarm of small robots that can work together to accomplish complex tasks. In the future, teams of intelligent robots could be deployed to tackle a number of challenging problems, from containing an oil spill to self-assembling into a piece of hardware after being launched into space. For now, the CU researchers, led by Assistant Professor Nikolaus Correll, have built a swarm of 20 robots, each about the size of a pingpong ball, in their lab.
