How do ants get around? Ultra-sensitive machines measure their every step

How do ants manage to move so nimbly whilst coordinating three pairs of legs and a behind that weighs up to 60 percent of their body mass? Scientists have recently developed a device that may reveal the answer and could even help design micro-robots in the future. Researchers used an elastic polycarbonate material to produce a miniature force plate. Springs arranged at right angles to each other enabled forces to be measured across the plate in the micro-Newton range.
