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 ...

On the move: Time sequence showing a robot swimmer following a curved trajectory to the upper left. The motion occurs over 520 s and the period of the external field is changed at the locations ...

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 ...

Fermilab scientists are developing one of the most cold-tolerant robots ever made so they can monitor the interiors of particle detectors. The Argonauts of Greek mythology braved sharp rocks, rough ...

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 ...
