The world’s smallest walking and shape-remembering robot
Illinois: A robot from Northwestern University is only half a millimeter in size. It bends, crawls, crawls and even jumps without any electric or hydraulic system.
This robot is made of shape memory and can be controlled by remote control. That is, as soon as the temperature rises, the robots return to their old form. It is then covered with a layer of thin glass that returns the robot to its original shape as the heat dissipates.
The robot is now heated by a scanning laser. When the laser hits a very small crab robot, it quickly spreads to the entire robot. It even moves up to 10 cycles per second. The direction of the robot is determined by the direction of the scanning laser. If you scan to the right, the robot will move to the right, and to the left, the laser will move to the left. It is also possible that the robot can cover half the distance of its size in one second.
First of all, all the parts of the robot were made smoothly and the substrate was applied to them and they were twisted. Then a light layer of glass is applied on them which reminds them of their shape and when the heat is removed it brings it back to its original shape.
Its main inventor, Professor John A. Rogers, says that due to its very slim size, the robot can enter the human body and perform many medical functions. Secondly, it can also be used in microfibration.
