Commonly, robots send to each other signals through Wi-Fi or Bluetooth, but these technologies are capable of transmitting only a limited number of signals, according to popmech.ru.
Meanwhile, scientists at Carnegie Mellon University's Robotics Institute have created new software, which enables a machine to understand the body poses and movements of people.
The ability to recognize poses, for example, will give people an opportunity more easily to communicate with computers simply by pointing at things.
Robots also learn the "chemical language" of pheromones, poorly understood by humans, but widely used by insects. Some models are already capable of tracing chemicals left on their LCD screens and use them for navigation.
