Self-governing cars are becoming increasingly denser in our lives, but scientists from the Harbin Institute of Technology (China) and the University of California (USA) apply developments in the automotive field to create autonomous nanorobots that will be able to "travel" by themselves, relying on analogues of technologies that already exist in the automotive industry.
The new "micromachines" have spherical micromotors measuring 5 micrometers, and when making short movements, they can independently pass a labyrinth of any shape. In fact, such "cars" have a great future in the field of biomedicine, where they can be used as capsules for targeted delivery of medicines, fight against tumor processes, act as diagnostic tools, and so on. According to lead specialist Longhue Lee,
"We connected the AI technology to the microbots. Due to this, the vehicle is able to navigate and maneuver in a complex and dynamically changing environment. Our tiny "robot cars" are able to move independently, avoiding collisions with obstacles and with each other. Previously, closed-loop systems were used to control microscopic vehicles. Our system allows us to conduct a micromachine through an environment that can change at any time and in which other microbots may appear. "
At the moment, the navigation is carried out as follows: the data of the main camera of the microscope comes in a kind of "navigational processor" that calculates the "displacement map". This card enters the scheduler program based on artificial intelligence, and it already compiles a list of possible ways of moving. After this, the choice of the optimal and shortest path is made, and the generator of the magnetic field forms a sequence of commands that cause motion.
"We plan to apply our technologies in the field of creating microbots for medical purposes and for manipulating nanoscale objects. Now we need to develop more sophisticated robot micro machines and a more sophisticated control system that will allow us to implement such functions as emergency braking, cruise control and a number of other important elements.
