Robot collective Magnetic microrobot swarms act as motors to move millimetre-sized passive objects without physical contact. (Courtesy: MPI-IS) Strong viscous interactions exist in microscale systems, ...

Inspired by how brainless lifeforms such as starfish and slime moulds move around, physicists have constructed 'odd' objects that autonomously roll, crawl and wiggle over unpredictable terrain, ...

Researchers in Switzerland have found a way of using sound waves to manipulate objects in disordered environments such as liquids. Instead of trapping the objects as conventional optical and acoustic ...
