Active matter, curved spaces: Mini robots learn to ‘swim’ on stretchy surfaces

Researchers used small wheeled robots to study indirect mechanical interactions on deformable surfaces, finding that active matter can interact through non-contact forces. They created a model to control collective behavior by modifying robot design, mirroring celestial bodies' paths in Einstein's General Relativity.
