Chinese researchers have developed what they say is the world’s smallest and lightest wireless robot that can change form to travel on land or in the air.
Inspired by Lego, it could potentially be used in complex environments like disaster rescue operations, according to the team from Tsinghua and Beihang universities.
Fundamental to the microrobot is a “morphable actuator” – a component that converts energy into force. The researchers said their new actuator could also be used to make medical devices and components for virtual and augmented reality.
“We introduce a synergistic design concept of small-scale continuously morphable actuators,” the team said in a paper published in the peer-reviewed journal Nature Machine Intelligence on April 18.
