Chinese Scientists Unveil Game-Changing Microrobot
A team of scientists from China has introduced a groundbreaking wireless microrobot, which they claim is the smallest and lightest in the world. This device can transform its shape for effective movement both on land and in the air, as reported by South China Morning Post.
The microrobot, 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 conditions, such as during rescue operations in disaster-stricken areas.
The core component of the microrobot is a "morphing actuator" — a device that converts energy into mechanical force. The team notes that their new actuator could also be applied in other fields, such as the creation of medical devices and components for virtual or augmented reality.
"Compared to other known wireless robots, our robot has the smallest size, lowest weight, and fastest land mobility in the world… This advantage significantly enhances the robot's endurance while maintaining the same energy consumption and provides better adaptability to the environment," said Zhang Yihui, a professor of mechanical engineering at Tsinghua University.
During testing, the microrobot was able to fly over objects and land, after which it switched to ground mode and continued to move. This system of switching between different configurations allows it to traverse slopes and other complex surfaces at varying heights.
Zhang also mentioned that the microrobot could be made suitable for various applications, including environmental monitoring and access to high-risk environments. Additionally, if necessary, the robot will be able to switch to a water movement mode.
