Light-guided bots are steered through mazes like spacecraft tugged by gravity



Summary

Researchers have developed tiny robots that navigate using light, mimicking how spacecraft are influenced by gravity. These “light-guided bots” have photosensitive films that move towards the light source. By shining light patterns onto a surface, scientists can create virtual pathways, guiding the bots through complex mazes with precision. This technology offers a new, non-invasive method for controlling micro-scale robots, potentially revolutionizing targeted drug delivery, microsurgery, and other applications requiring fine manipulation in confined spaces. The approach simplifies control compared to traditional methods and holds promise for automation in complex, miniature environments.
