Description

technical field [0001] The invention relates to the technical field of robots, in particular to a wireless communication system for a multifunctional robot. Background technique [0002] The birth and application of robots are closely related to social development and production needs. It has been widely used in many fields such as industrial production, resource development, disaster relief, military technology and social services. Robots can not only protect against toxic, dust, noise and radiation It can partially replace human operations in such harmful environments, and can also complete the tasks assigned by people in extreme conditions that humans cannot reach, such as deep sea and outer space environments, thus expanding the ability of humans to transform nature.

Problems solved by technology

[0003] With the development of large-scale social production, dozens or even hundreds of robots have appeared on the production line. This kind of social production objectively requires us to study multi-robot systems. However, if we simply combine multiple robots If they are merged together, it is very likely that there will be conflicts and confrontations between robots, which will make the overall performance very low or even unable to work. In view of this, it is necessary to carry out research on the theory, architecture, communication between robots and group cooperation of multi-robot systems. Research on key issues such as methods, in order to achieve the goal of robot groups to cooperate with each other

[0004] Recently, the research content in the field of multi-robots mainly includes control structure or architecture, communication and conflict resolution. Among them, control structure and communication problems belong to the advanced control tasks in multi-robot systems, and conflict resolution includes deadlock prevention and conflict resolution. Problems such as collision avoidance and path planning belong to low-level control tasks in multi-robot systems. In practical robot wireless communication networks, the problem of "hidden terminals" is often encountered. In the multi-robot communication system, some robots cannot receive the signals transmitted by other robots, so they cannot communicate

In the wireless communication system using CSMA protocol, the hidden terminal problem will directly affect the result of carrier detection, thus deteriorating the system performance
