Embodiment Construction

[0038] In order to further explain the technical means and effects that the present invention adopts to achieve the intended purpose of the invention, below in conjunction with the accompanying drawings and preferred embodiments, the specific implementation, structure, features and effects of the present invention will be described in detail as follows: rear.

[0039] The research background of the present invention is as figure 1 As shown, in real life, it is often necessary to use robots to complete search tasks, such as the search for fire ignition points, radioactive substances or odor sources, etc. The search environment usually contains obstacles (walls, etc.), and the search target position is also unknown. .

[0040] The overall structure diagram of the reinforcement learning algorithm involved in the robot joint search system based on multi-agent reinforcement learning is as follows figure 2 As shown in Fig. 1, the robot Agent obtains state values ​​from the search...

Abstract

The invention relates to a multi-robot combined target search system, and in particular relates to a multi-Agent based robot combined search system by reinforcement learning. The system provided by the invention performs search on the condition of uncertain target location and uses a reinforcement learning algorithm which can not only accelerate the search speed, but also improve the search efficiency, thus effectively avoiding the problems of robots hitting a wall and collision among the robots and the like. The system is especially applied to search in dangerous regions or regions that human cannot reach, thereby the purposes of saving the search time, expanding the search region and better protecting personal and property safety and the like can be reached.

Description

technical field [0001] The invention relates to a multi-robot joint target search method, in particular to a multi-robot joint target search method based on multi-Agent reinforcement learning. Background technique [0002] Target localization and search in an unknown environment is a very suitable problem for mobile robots to solve. This automated method saves more time and resources than other search methods, and is particularly suitable for searching areas that are dangerous or inaccessible to humans. At present, multi-robot joint search technology is becoming an important direction in the field of robot research. [0003] A multi-robot system usually needs to be composed of several specialized subsystems that have both division of labor and cooperation, coordination and competition. Designing the whole system with traditional centralized control or layered control will encounter some insurmountable difficulties. The emergence of multi-agent technology provides a new id...
