ISTANBUL (AA) – A Chinese research team has developed the world’s smallest and lightest wireless amphibious robot, capable of transforming into any desired shape, The Global Times reported Sunday.

The robot, developed by researchers at Tsinghua University, measures 9 centimeters (3.5 inches) in length and weighs just 25 grams (0.88 ounces). It can reach speeds of up to 1.6 meters (5.2 feet) per second on land.

The team recently designed a miniature actuator that allows microrobots to continuously shift shape and “lock” into specific configurations, significantly improving their adaptability in different environments.

Using this actuator in a modular building block-style design, the researchers created the amphibious robot, which can transform its structure to run and fly, demonstrating advanced agility and maneuverability.

The robot is made up of several components, including rotors, a motor, a controller, and a power supply, all powered by actuators, according to Zhang Yihui, the professor who led the research team.
