Researchers from China have unveiled a new microbot that is considered the smallest and lightest in the world. According to South China Morning Post, it features a unique ability to change its shape for movement both on land and in the air.

This microbot, inspired by LEGO designs, was developed by a team from Tsinghua University and Beihang University. It measures just 9 centimeters in length and weighs 25 grams. It's designed to operate in extreme conditions, such as during rescue missions in disaster zones.

The core of the microbot is a "morphing actuator", a component that converts energy into mechanical force. The researchers note that this new actuator could be applied in various fields, including medical devices and components for virtual or augmented reality.

"Our robot stands out as the smallest, lightest, and fastest among known wireless robots. This significantly enhances its endurance while maintaining the same energy consumption, allowing for better adaptability to various environments," says Zhang Yihui, a professor of engineering mechanics at Tsinghua University.

During tests, the microbot successfully flew over obstacles and then switched to land mode to continue moving. The switching system between configurations allows it to traverse slopes and other challenging surfaces.

Zhang also mentions that the microbot can be tailored for various applications, including environmental monitoring and operation in high-risk environments. Additionally, it can switch to a water movement mode if necessary.
