  • Scientists have borrowed a new way to navigate ants


    Researchers from the Massachusetts Institute of technology have created an unusual robot. During its development, experts were inspired by the ability of ants to determine the location in the sky. This method was one of the most accurate in comparison with other methods of navigation without the use of GPS.

    Usually, ants to determine the location are guided by traces of aromas or pheromones, but in the desert, it is not possible to do this — chemicals evaporate under the scorching sun. Therefore, insects have learned to navigate the sky, using polarized sunlight to determine the course and counting the steps taken to calculate the distance.

    The presented robot is equipped with two light sensors with a resolution of only 14 pixels each, supplemented by rotating polarized filters. Tests have shown that this method of positioning does not become less accurate with increasing distance, as other types of navigation without the use of GPS.

    "The average error recorded during the overall trajectory was only 0.67% in lighting conditions, which is similar to the one faced by ants," the researchers said in a report.

    This method in addition to ease of use is quite available. Scientists believe that the system can be used in self-driving cars as a backup in case of failure of traditional GPS navigation.
