Researchers have created a micro-robot whose electroadhesive foot pads, inspired by the pads on a gecko’s feet, allow it to climb on vertical and upside-down conductive surfaces, like the inside walls of a commercial jet engine. Groups of them could one day be used to inspect complicated machinery and detect safety issues sooner, while reducing maintenance costs.
