The next time you hear an insect crawl on your skin, do not be afraid — it may be a small robot crab. (Okay, you might have some fears.) Engineers at Northwestern University have identified the crab as the smallest robot ever controlled. According to a new team paper published Wednesday in the journal Science Robotics, the machine is half an millimeter wide and can sit on the edge of a cent with space to leave. Sadly, researchers are also able to build countless other devices inspired by creatures, including robotic beetles, crickets, and inchworms. After all, they were so busy with their lives that they did not stop thinking about building reptiles. While the spine is shaking, the team believes that their equipment is a major step forward in creating functional robots that can perform remote controlled tasks in small areas. “You may think of robots as agents or mechanics in the industry or as surgeons to remove blocked arteries, stop internal bleeding, or eliminate cancerous growths — all with less invasive procedures,” says John A. Rogers. professor of building science and engineering at Northwestern University and lead author of the study, in a press release. The robot is not controlled by electricity. It is made of a mixture of standing memory that allows it to evolve into a state of burnout before returning to a cooler state. Using a laser beam, the team was able to heat some parts of the robot that caused it to “move.” For example, moving the laser from left to right . "Because these buildings are so small, the cooling rate is very fast," Rogers said. "In fact, reducing the size of these robots allows them to run faster." Crabs can crawl, crawl, and jump using this technique. Of course, it is not yet fully operational considering that it needs a laser pointed at it in order to move. But it opens the door to the future, and the little robots are very advanced… which they hope will not take over the world in large quantities. Smaller than fleas, a few robotic crabs stand together.
