Scientists have developed a wireless micro robot, which can fly by supplying power with a laser

for all UL machines to be unveiled again at this event, the power source is a very critical basic problem, but it is even more so for micro robots. Using batteries is too heavy, and relying on wires to connect power makes the application full of restrictions; Now scientists have finally found a breakthrough. They have developed a wireless micro robot robofly that flies with power supplied by a laser

The fixture obtained according to such three standards

according to the report of new atlas, robofly is made by the technical team of the University of Washington, and its weight is about the same as a toothpick; Although the time is very short, it is still the first successful wireless micro robot in the world

robofly uses lasers to supply power; The laser will irradiate the solar panel on robofly's head, providing 7 volt power for the robot; The micro transformer carried inside will convert it into 250 volts required for flight. At the same time, researchers have also built a microcontroller to control the wings, so that the robot does not have to rely on lines to connect with the outside world

the demonstration in the video may seem to make you feel "very empty", or "Er, that's it?" This is because the laser used in the current experiment has no technology to track the robot. Once the robot rises out of the laser range, it will fall due to lack of power

"IEEE spectrum" mentioned that this technology, which enables laser to track solar panels, has been developed by other scholars and has achieved certain results. Although it is a little weak at present, it may not be a big problem; The research team has been able to continuously develop the power battery recycling at a distance of 1.23 meters indoors to remotely power the robot. If you replace the laser with a stronger success rate, it is not a problem to expand the control range to tens of meters

in addition, researchers are also testing the feasibility of using radio wave signals to charge, so that the robot can adjust the power supply mode according to the task type

when it comes to the application of this kind of micro robot, you may think of eavesdropping, reconnaissance, etc., which are used as movie plots, but in the vision of researchers, they have a more environmentally friendly imagination of micro robots: in the future, you can take suitcases with countless roboflys and release them in the destination, so that they can surround buildings and look for pipeline cracks, Reduce the leakage of greenhouse gases such as alkane in houses with an area of 100 square meters, and do our part for the earth
