Since GPS does not work well inside buildings, the robots have to get to the building within the building. Orientation is usually done using cameras and LiDAR modules to identify objects and special objects. However, sensors are expensive and absorb a lot of energy, cameras are useless in the dark. A new way of orienting robots in space was invented by the University of California at San Diego – it was based on external Wi-Fi access points, of which there are plenty in many buildings.

Using a simple Wi-Fi transceiver, the robot communicates with the points. It receives return signals that detect deviations at any angle and with a solution, which are calculated by measuring the time between sending a signal and returning it. The onboard computer records how these values ​​change as the robot moves, and p. However, the camera can also be useful for overcoming a small obstacle.

The setleyball fnom protest method, the entire body of the wheeled robot was forced to drive around a steep floor until January s In the end, the functions were oriented satisfactorily and the waves coincided with the capabilities of the sensor cameras
