How many robots do you need to drag a whale?
Scientists have created a miniature robot that can carry a mass that exceeds its own by a factor of 2000.
Another highlight of robotics from scientists from Stanford. This time, developers from the Biomimetics and Dextrous Manipulation Lab managed to create a 12 gram MicroTug (Microbuxyer) robot that can drag an item 2,000 times the weight of its body. It is like harnessing a man to pull a blue whale on the ground.

To put it more precisely, the robot is able to give 40 Newton when shears an object on a flat surface. Many of you would have thought that the developers were able to see the principle of action from the ant. But no! When creating a robot, scientists took as a basis the structure of the gecko's paw, which is famous for its sticky fingers.
To move objects, MicroTug uses a controlled adhesive material that makes it stick to the surface for the duration of the pull. Then the bot pushes the load towards itself with small jerks to reduce energy consumption. With such forward movements, the small tug pulls out more on itself than any insect. For comparison: an ant can lift a thing 100 times its own weight (10N) and drag something 30 times heavier than itself.
To break insect records, the developers also created a MicroTug modification capable of lifting objects on a sheer surface. Namely, the 9-gram model of the “crane operator” pulling a weight 100 times the size of its own. It is approximately as if Tom Cruise from Mission Impossible 4 was pulling the elephant along the sheer surface of the skyscraper.
While tugs are too small to use them in industry or transport, however, he will bring a cup of morning coffee without any problems.
