Washington State University has developed two insect robots, a mini-bug and a water strider. The micro-sized robots were created with the hope that thy could one day carry out human roles in artificial pollination, search and rescue, environmental monitoring, microfabrication, and robotic-assisted surgery in mind. Both the mini-bug and water strider can move 6mm a second. Conor Trygstad, a PhD student at the School of Mechanical and Materials Engineering, who led the research, said: “That is fast compared to other micro-robots at this scale, although it still lags behind their biological relat…
