A team of researchers from MIT and universities in Hong Kong has developed a lightweight jumping robot that uses a unique combination of springs and wings. This innovative robot weighs just one gram and stands a little over five centimeters tall. Instead of flying or moving along the ground, it jumps, allowing it to overcome obstacles with minimal energy consumption.

The robot features a spring-loaded body made from carbon fiber, which acts like a jumping leg. It is equipped with four movable wings inspired by insects, which are powered by artificial muscles activated by electricity. Currently, the robot relies on an external power source and is guided by a motion tracking system. When it lands, the spring compresses, storing mechanical energy that is released to propel the robot up to 20 centimeters high and at a speed of about 30 centimeters per second.

This jumping mechanism is more energy-efficient than traditional flying methods, consuming up to 64% less energy than a typical drone for the same distance. The researchers plan to enhance the robot with an internal battery and independent tracking system for future missions, including potential applications in rescue and exploration in hazardous environments.
