Researchers in China have unveiled a new wireless micro robot, claimed to be the smallest in the world. Its unique feature is the ability to change shape for efficient movement on land and in the air, according to the South China Morning Post.
This micro robot, developed by teams from Tsinghua University and Beihang University, measures just 9 centimeters in length and weighs 25 grams. It is intended for use in extreme conditions, such as rescue operations in disaster-stricken areas.
The innovation behind the micro robot lies in its "morphing actuator" - a component that converts energy into mechanical force. Researchers point out that this new actuator could be applied in various fields, including 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 speed in the world... This advantage significantly enhances the robot's endurance at the same energy consumption and provides it with better adaptability to the environment," says Professor Zhang Yihui from Tsinghua University.
During testing, the micro robot was able to fly over obstacles, land, and then switch to ground mode to continue moving. This switching system between different configurations allows it to traverse slopes and other complex terrains at varying heights.
Zhang also mentioned that the micro robot could be tailored for various applications, including environmental monitoring and access to high-risk areas. If needed, it could also switch to a water movement mode.
