Insect-level robots, with their compact size, can perform tasks in areas inaccessible to larger robots. However, they are limited by their energy reserves and struggle to overcome large obstacles. Researchers abroad have developed a micro jumping robot that can easily leap over obstacles, traverse rugged terrain, and operates with low energy consumption.
Micro jumping robot.
This micro jumping robot stands 5 centimeters tall and weighs less than 1 gram, lighter than a paperclip. Its body is supported by a “spring leg,” with four flapping wings providing lift and controlling direction. The “spring leg” can jump and converts the kinetic energy of the jump and the potential energy of the descent into usable energy.
The robot can jump approximately 20 centimeters into the air, effortlessly leap over icy surfaces and wet, rugged terrain, and even jump onto hovering drones. Its energy consumption is 60% lower than that of other similar robots, while its payload capacity has increased tenfold. With future technological upgrades, the application prospects of this robot are worth noting.
