Harvard University researchers have programmed a robot swarm of more than 1,000 bots that can self-assemble into two-dimensional shapes. The “Kilobots” are roughly the size of a penny, and cost $14 in parts. It takes only a few minutes to put a Kilobot together. In order to program them at the same time, the roboticists use an infrared light from an overhead controller, which gives instructions. Infrared signals also help the robots communicate with each other to create formations. Continue reading Harvard University Researchers Create Biggest Kilobot Swarm
