In California, engineers from Stanford University built tiny robots, who can climb walls and can attract more than 100 times their weight. Their feet have a special material with many tiny nails, inspired by the foot of the lizard.
For example, the robot named “mTug” and weighs 12 grams, can draw an object 2.000 times heavier. Larger sizes robot like this could be very useful for constructions, but rescue operations. This technology will be presented at the International Conference on Robotics and automation next month in Seattle.
