Tiny robot insects might seem little more than fun, geeky gadgets to some, but the potential for these cyber-critters in areas like search and rescue, agriculture and hazard detection is massive – and so are the hurdles. Power-supplies, onboard-sensors, control and stability are all problematic at the micro-scale. It’s this last issue – stability – that researchers at the University of Southern California (USC) have been working on with their Bee+, drawing inspiration – yet again – from the insect world. read more
