University of Sheffield engineers have developed a way of making hundreds — or even thousands — of tiny robots cluster to carry out tasks. The robots do not require memory or processing power.
Each robot uses just one sensor that indicates the presence of another nearby robot. Based on the sensor's findings, the robots will either rotate on the spot, or move around in a circle until one can be seen.
Until now, robotic swarms have required complex programming, complicating the development of miniaturized, individual robots. With the programming created by the Sheffield team, however, nanoscale machines are possible.
