Scientists have built a jumping robot inspired by the grasshopper that can leap 27 times its body length.
Swarms of the locust-like drones could one day be used to explore remote areas of the Earth or other planets, say the researchers.
The device, which looks like the workings of a watch perched on two long feet, weighs just seven grams, but it can jump 1.4 metres - 10 times further for its size and weight than any other robot.
Professor Dario Floreano, who led the team from the Laboratory of Intelligent Systems at the Ecole Polytechnique Federale de Lausanne in Switzerland, said: "This biomimetic form of jumping is unique because it allows micro-robots to travel over many types of rough terrain where no other walking or wheeled robot could go.
"These tiny jumping robots could be fitted with solar cells to recharge between jumps and deployed in swarms for extended exploration of remote areas on Earth or on other planets."
