A total of 100 g of extremely tiny robots pulls 1.8 tons of cars Amazing movies are being released

Minimal robot that can move even if it is much heavier than I am "MicroTug"Has organized a team with six bodies, a phenomenal image has been released that is pulling a heavy car by about 18,000 times more than ourselves.

The way you actually move the car can be seen from the following movie.

Let's all Pull Together: Team of μTug Microrobots Pulls a Car - YouTube


Ali is a strong man who can lift up to 100 times its own weight.


It is possible to move huge insects by matching power.


Such ants are also popular research subjects among researchers, and Stanford University was born as a result of studying that "Ali can carry many times larger things of himself" is a micro-size robot "MicroTug"


Although MicroTug can not pull the object vigorously, it has a special foot inspired from gecko 's legs and it can pull slowly even huge objects by sticking firmly to the ground.


MicroTugFrom here it seems that lightly moving your weight of 2000 timesBut you can see.


There are also types of power that robots can demonstrate, and there are also types of robots that demonstrate great power in a moment.


Even if such a robot combines the power of 20 bodies, it can only demonstrate the power of two bodies.


On the other hand, a robot type robot that is not speedful but one step by step is suitable for team work like MicroTug. You can carry huge objects with strength like ants.


After repeating some experiments ......


The research team discovered a method that uses multiple robots to demonstrate a stable and powerful power.


The six small robots are lined up side by side ... ...


What a car. The robot is about 3.5 ounces (about 100 g) even if 6 bodies are combined, but the weight of the car is 3900 pounds (about 1.8 tons).


Looking from above it looks like this. The robots are slowly moving the car while repeating or stopping.


When checking the position of the tire, the tire is on top of the line at first ... ...


You can see that the tire is progressing gradually.
