Taking a cue from biological cells, researchers from MIT, Columbia University, and elsewhere have developed computationally simple robots that connect in large groups to move around, transport objects ...

Particle robots are made of identical particles that interact weakly via magnets. These particles do not have individual locomotion abilities but can only expand and contract. Collectively, the robot ...

In physics, particles are small localized objects with physical characteristics like mass or volume. From those humble ingredients, our virtually limitless universe is built. The concept, presented in ...
