Engineers at Stanford University, California, have built a super-strong tiny robot that is capable of carrying things that weigh more than 100 times its own weight.
The design of this tiny robot is inspired by geckos and the way it moves is copied from an inchworm. The secret to its ability to lift heavy things comes from the adhesives attached on its feet, this stabilizes and helps it to climb a wall even with heavy loads.
However, of all the tiny robots that can carry things over 100 times their own weight, the most impressive one is the robot nicknamed μTug. It weighs just 12 grams but it can drag a weight 2000 times heavier.

If a tiny bot can do this much of work, imagine a robot even larger with this strength can do.
