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.
Yaser Sheikh, one of the experts involved in the project, said that these methods will create new ways for people and robots to communicate with each other, as well as give the robots a chance to better understand the world around them.
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.
