Particle Robot Moves towards the Light.
The particle motion can be phase-modulated by an environmental stimulus, such as a light source. Here, we show a particle robot in which each component measures its light intensity, broadcasts its value to the group, and receives the intensity values of its neighbors to determine its phase delay. This produces undulating motion, with net movement towards the light source.
