Through the embodiment, the first robot and the second robot are detected to compete to pass through the first area, wherein the passing width of the first area only allows one robot to pass through; controlling the first robot to pass through the first area under the condition that the priority of the first robot passing through the first area is higher than that of the second robot passing through the first area; in the process of controlling the first robot to pass through the first area, the second robot is controlled to be located at a position outside the first area, the problem that in the process of simultaneously driving a plurality of robots in the same building in the related art, when the robots pass through a gate, a narrow passage or an elevator, the running efficiency of the robots is low due to possible occurrence of collision, blocking and the like is solved, the running efficiency of the robots is improved, and the service quality is improved.
In step S202, it is detected that the first robot and the second robot compete to pass through a first area, wherein a passage width of the first area allows only one robot to pass through.
The first robot and the second robot may be distribution robots that distribute articles within the same building. Within the same building, the delivery robot can move according to a moving path configured by a server (e.g., a cloud server). The cloud can configure the movement paths of all connected robots. For the distribution robot, a passable area, a competitive area, and a non-competitive area within the building may be set, wherein,
(1) the path is a path of a possible depending position of a robot connected to the cloud end edited by the cloud end. The robot will follow the path and if the path is occupied, the robot will bypass itself.
(2) The passable area is an area allowing the robot to travel. The passable area can be determined by setting the middle passing width on the left and right sides of the point on the path.
(3) The competition area is an area along the path that allows only one robot to pass through (e.g., the competition area may be an area along the path that has a passable width of less than 2 m). When the 1 st robot occupies the competition area and the 2 nd or more robots want to occupy the competition area, the scheduling behavior is executed. The contention region may include a first region.
(4) A non-competitive region is a region along the path that allows more than 1 robot to pass through (e.g., a non-competitive region may be a region along the path that has a passable width greater than 2 m). The non-contention region may include a second region.
Optionally, one or more scheduling points may be preset in each non-contention region, and the scheduling point may be any position in the middle of the non-contention region. At each scheduling point, when a plurality of robots compete to pass through the competition area, the robots competing to the first area can be parked at one parking point, so that the subsequent scheduling can be conveniently carried out under the condition that the running of other robots is not influenced.
At the cloud, the building can be represented as a Graph data structure, and each edge adds attributes including whether there is a competitive region, and the coordinates of a scheduling point (which can be in a non-competitive region), where the scheduling point is not the vertex of a non-competitive edge; a non-competitive edge can continue to be split into multiple non-competitive edges by adding control points (to avoid scheduling points too far).
For example, for a route and a passable area within a building on the map shown in fig. 3, the cloud may construct it as a graph as shown in fig. 4, on which a competitive area, a non-competitive area, and a dispatch point are displayed.
Optionally, in this embodiment, the detecting that the first robot and the second robot compete to pass through the first area includes: acquiring a first position where a first robot is located and a second position where a second robot is located; and determining that the first robot and the second robot compete to pass through the first area according to the first position and the second position.
Navigation behaviors (e.g., a starting point, a target point, and a route from the starting point to the target point of a navigation task) of all robots (robots connected to the cloud) are issued by the cloud. The robot can send its positional information to the high in the clouds in real time, and the high in the clouds can be through receiving the real-time position that first robot and second robot sent, obtain the first position that first robot is located and the second position that the second robot is located.
The robot comprises a first robot and a second robot, wherein the first robot and the second robot are provided with positioning modules for positioning, the positioning modules can be GPS (Global positioning System) modules or WIFI modules, the robot and a cloud end can be in wireless connection (for example, 4G, 5G and the like) through establishment, communication is carried out by using the established connection, for example, the cloud end sends a distribution instruction, a navigation task (which can comprise a mobile route) and the like to the robot through the established wireless connection, and the robot can send positioning information to the cloud end through the established wireless connection.
For example, the first robot and the second robot may periodically (e.g., 1s, 3s, 5s, etc.) acquire real-time positions and send acquired position information (first position information indicating a first position and second position information indicating a second position) to the cloud server.
After obtaining the first location and the second location, the server may determine that the first robot and the second robot compete to pass through the first area according to the first location and the second location.
Through the embodiment, the robot is determined to compete to pass through the competition area according to the position information of the robot, the accuracy of the determination result can be ensured, and the control capability of the robot is improved.
In a scene that a plurality of distribution robots operate in the same building and only accommodate 1 robot to operate in narrow passages, elevator cabs and the like, the robot can not pass smoothly and is blocked when more than 1 robot passes through the narrow passages or is navigated by taking advantage of elevator cross-floor navigation.
In order to ensure that the delivery robot can safely use the elevator, a server for controlling the robot can communicate with an elevator center (or, the two can be integrated into the same device), a special command is sent to the elevator center, the robot is controlled to press an elevator taking button at a first floor (a floor where the robot is to enter the elevator), after the elevator reaches the first floor, the elevator center sends indication information for indicating that the elevator reaches the first floor to the server, and the server sends an elevator command to the robot to control the robot to enter the elevator. The target floor (the destination floor on which the robot takes the elevator) is pressed for the robot after the robot enters the elevator. When the elevator arrives at the destination floor, the elevator center can send instruction information for instructing the arrival of the destination floor with the server, and the server sends an elevator command to the robot to control the robot to move out of the elevator.
It should be noted that the robot may also interact directly with the elevator center through network connection, and the elevator center controls the robot to press the elevator riding button, control the robot to enter the elevator, press the target floor for the robot, and control the robot to move out of the elevator.
For different scenarios, it may be determined in a number of ways that the first robot and the second robot compete to pass through the first area. The behavior of occupying the contention region (contention through the first region) may be: the robot position enters the range of a competition area (a first area); or the elevator center sends the destination floor to arrive (after the robot arrives at the destination floor, the robot moves out of the elevator and can enter the competition area).
For example, for a scene in which two robots move in a specific direction (the moving directions of the two robots may be the same or different) and enter a first area, it may be determined that the first robot and the second robot are both located in the first area according to the first position and the second position, and then it is determined that the first robot and the second robot compete to pass through the first area.
For another example, for a scene that one robot moves in a specific manner and enters a first area and another robot arrives at the first area by taking an elevator, it may be determined that the first elevator where the first robot is located arrives at a target floor corresponding to the first area according to the first position and the second position, and the second robot is located in the first area, where the target floor is a target floor where the first robot takes the first elevator, and the first area includes an exit area of the target floor; or, it may be determined that the second elevator where the second robot is located reaches the target floor corresponding to the first area according to the first position and the second position, and the first robot is located in the first area, where the target floor is a target floor where the second robot takes the second elevator, and the first area includes an exit area of the target floor.
For another example, in a scenario where two robots both take elevators (may take the same elevator or different elevators) to reach a first area, it may be determined, according to the first position and the second position, that a first elevator where the first robot is located and a second elevator where the second robot is located reach a target floor corresponding to the first area at the same time, where the target floor is a target floor where the first robot takes the first elevator and a target floor where the second robot takes the second elevator, and the first area includes an exit area of the target floor.
Through the embodiment, the robot is determined to compete to pass through the competition area in different modes aiming at different scenes, so that the accuracy of the determination result can be ensured, and the control capability of the robot is improved.
In addition to determining that the robot competes for passing through the competition area based on the position information, the server may determine that the robot competes for passing through the competition area in other manners. For example, the first area may be photographed by a camera (or other image capturing device) disposed in the first area or at a position where the first area can be photographed, and it is determined that the robot competes for passing through the competition area according to robot information (whether the robot is included, which robots are included) included in the photographed image.
In determining the robot information included in the photographed image, the robot included in the photographed image may be determined according to the characteristics of the robot, and a number (e.g., an actual number, a graphic code representing the actual number) of the robot may be recognized at a specific position of the included robot, so that the server manages the robot.
Optionally, in this embodiment, the detecting that the first robot and the second robot compete to pass through the first area includes one of:
(1) detecting that a second robot enters a first area in a case where the first robot is located within the first area;
(2) detecting that the first robot enters the first area in a case where the second robot is located within the first area;
(3) detecting that the first robot and the second robot enter a first area simultaneously;
(4) under the condition that the second robot is located in the first area, detecting that a first elevator where the first robot is located reaches a target floor corresponding to the first area, wherein the target floor is a target floor of the first robot taking the first elevator, and the first area comprises an exit area of the target floor;
(5) under the condition that the first robot is located in the first area, detecting that a second elevator where the second robot is located reaches a target floor corresponding to the first area, wherein the target floor is a target floor of the second robot taking the second elevator, and the first area comprises an exit area of the target floor;
(6) and detecting that a first elevator where the first robot is located and a second elevator where the second robot is located reach a target floor corresponding to the first area at the same time, wherein the target floor is a target floor where the first robot takes the first elevator and a target floor where the second robot takes the second elevator, and the first area comprises an exit area of the target floor.
The detection process may be performed using the position information of the first robot and the position information of the second robot, or may be performed using image information captured by the camera.
Through this embodiment, adopt different modes to confirm that the robot competes through the competition area to different scenes, can guarantee the accuracy of result of confirming, improve the control ability of robot, provide the basis for the dispatch of robot simultaneously, improve the accuracy of dispatch.
The first robot and the second robot may travel in the same direction or in opposite directions in the first area (the two robots travel in the first area in opposite directions). In order to improve the task execution efficiency of the robot, the operation efficiency of the robot is ensured, and the robot with the opposite traveling direction can be controlled.
In step S204, the first robot is controlled to pass through the first zone if the priority of the first robot passing through the first zone is higher than the priority of the second robot passing through the first zone.
After it is detected that the first robot and the second robot compete to pass through the first area, the priority of the robot passing through the first area can be judged, and the robot is controlled according to the priority.
