Researchers from Northwestern University have successfully created the world’s smallest remote-controlled robot capable of walking. At just half a millimeter wide, this super robot can fit inside the edge of a coin.
This super robot is modeled after a small crab, which can walk, crawl, bend, squirm and even jump.
Yonggang Huang, the leader of the research team, said that this tiny super robot can walk at an average speed of half the length of its body per second. The researchers used a special alloy material that can change shape when heated to create this robot instead of relying on tiny electronics. They use precision lasers to quickly heat specific parts of the robot, thereby causing it to change shape.
The robot will return to its original shape thanks to a thin layer of glass that helps cool the robot. Due to the very small structure, the cooling speed of the robot is very fast.
These super robots can be applied in medical surgeries to help patients not have to operate like before. For example, the robot can open clogged arteries, stop internal bleeding or remove cancerous tumors… In addition, this tiny robot can also help repair or assemble small structures or machines in hospitals. industry.
Currently, this mini super robot is still in the testing phase. Researchers will continue to improve it to make it even more advanced.
