An ongoing study out of Rice University is using free online games to crowd source information to help them refine control algorithms for robotic swarms. And anyone can play! Each time a player successfully navigates a group of robots through a maze or obstacle, the website gathers data about how the task was completed. Researchers are looking how such swarms could have medical applications such as swarming a tumor with a payload of anti-cancer drugs using MRi signals. One post-doctoral researcher at Rice demonstrated how a swarm of randomly scattered robots could be directed to form a complex shape…in this case the letter R.
