Embodiment 1
[0077] Embodiment 1 describes a multi-robot collaborative operation system, which includes a hardware part and a software part.
[0078] combine figure 1 As shown, the hardware part includes a server (computer) and multiple robots (executive bodies).
[0079] The server is used for resource management of the entire scheduling system, receiving external tasks, performing logical operations and sending scheduling instructions.
[0080] Robots include but are not limited to planar handling robots, such as forklift robots, AGVs, etc.
[0081] In addition, the multi-robot collaborative operation system also includes two communication links, one of which is a global communication link, and the other is a local communication link between two robots, that is, an ad hoc peer-to-peer communication network.
[0082] The global communication link is used for global scheduling based on the stopping point mechanism under normal conditions, and the peer-to-peer communication network of the...
Embodiment 2
[0109] Embodiment 2 describes a method for dynamic avoidance of multiple robots during collaborative operation, which is implemented based on the multi-robot collaborative operation system in Embodiment 1 above.
[0110] Such as image 3 As shown, a dynamic avoidance method for multi-robots during collaborative operations includes the following steps:
[0111] Step 1: The server side (central scheduling server) abstracts and manages scheduling resources.
[0112] Scheduling system resources include running scenarios, robot walking paths, and current running status information of all robots.
[0113] I. Abstract the topological frame of the operating scene, perform an abstract summary of the overall operating scene according to the on-site operating space and the deployment status of the workstations, and extract the topological frame diagram of the operating scene. Typical topologies supported in this embodiment include checkerboard topology, U-shaped crossover topology, and...

Abstract
The invention discloses a dynamic avoidance method for multiple robots in collaborative operation. The method comprises the steps: carrying out the path pre-planning of all tasks in a task pool according to the priorities, and reducing the conflict intervention between robots from a planning layer; monitoring the current operation states of all the robots, dynamically pre-judging the safety distance, generating different types of stop points, coordinating the operation of the robots, and solving the technical problems of collision, delay, interlocking and the like during the cooperative operation of the robots. Overall scheduling is carried out to optimize resource distribution, traffic control and coordinated avoidance are achieved, local peer-to-peer communication solves the overall operation problem after the robot individual is abnormal, and therefore the robustness of the whole scheduling system is guaranteed. The method is suitable for multi-robot scheduling avoidance scenes suchas factory automation and storage commodity transfer.
Description
technical field [0001] The invention relates to a dynamic avoidance method of multi-robots during cooperative operation. Background technique [0002] In the environment of rapid development of logistics, industrial production and warehousing, more and more companies are accelerating the process of unmanned warehousing. With the increasing demand for warehousing scenarios, a warehousing usually requires several, dozens, or even more multitasking robot. This puts forward higher requirements for avoidance in the same scene. At present, most domestic robot manufacturers are in the early stage of development, and the avoidance and scheduling research of multi-robots started relatively late. Due to the difficulty and complexity of avoidance and algorithm implementation, most manufacturers do not have mature, reliable and efficient solutions. With the development of the market, it is urgent to solve the dynamic avoidance problem of multi-robots. Contents of the invention [0...
