Homogeneous Swarm Robotics demonstrating 100-1024 robots in a shape formation simulation is a project by Hanlin Wang and Michael Rubenstein of the McCormick School of Engineering in Northwestern University. Their work was also presented in the IEEE Transaction on Robotics. The video starts out with the first demonstration with 100 physical robots forming the letters “N” and “U” in sequence. The first simulation is sped up to 4x in regular speed. 100 simulated robots start randomly dispersed, and the algorithm drives the swarm to the goal shape, the letter “N”. Robots use hop count information to detect when the first letter is complete. They then switch to form the second goal shape, the letter “U”.
The second demonstration has 1024 physical simulated robots form the letters “N” and “U” in sequence. The simulation is sped up to 10x in regular speed. Robots also start randomly dispersed. They also form the letter “N” as the first goal shape then switch to the letter “U”. The robots also use hop count information once the first letter was completed. In both simulations, the robots are circular in shape and can move seamlessly in the four cardinal directions when transitioning to the next goal letters.
