Chinese scientists have unveiled a new wireless microbot, which they claim is the smallest and lightest in the world. One of its main features is the ability to change shape for movement on land or in the air, as reported by the South China Morning Post.

The microbot, inspired by LEGO, was developed by researchers from Tsinghua University and Beihang University. It measures just 9 centimeters in length and weighs 25 grams. This device can be utilized in challenging situations such as rescue operations during natural disasters.

The foundation of the microbot is a "morphing actuator," a component that converts energy into force. The team notes that their new actuator can also be applied in other fields, such as creating medical devices and components for virtual or augmented reality.

"Compared to other known wireless robots, our robot has the smallest size, lightest weight, and fastest land mobility in the world... This advantage significantly enhances the robot's endurance at the same energy consumption, providing better adaptability to the environment," says Zhang Yihui, a professor of engineering mechanics at Tsinghua University.

During testing, the microbot was able to fly over objects and then switch to land mode, continuing its movement. This switching system between different configurations allows it to navigate slopes and other complex surfaces at various heights.

Zhang also states that the microbot can be adapted for various applications, including environmental monitoring and access in high-risk environments. If needed, the robot can switch to a water-moving mode.
