Flexible foot pad lets the Hopcopter hopping drone land on ice, sand and rocks

University of Toronto researchers designed a wider, spiked foot pad with rubber-band return springs for the Hopcopter, a one-legged hopping quadcopter from City University of Hong Kong and HKUST. Tests on ice, sand and rocks showed 84% less performance variation across terrains. The team is commercializing the design as Hop-1, aimed at search and rescue and remote inspection.
