This application provides an obstacle avoidance method and apparatus, an electronic device, and a storage medium. The obstacle avoidance method is applicable to a robot. The robot is configured to move along a track in a rack area, and the method includes: detecting whether a suspected obstacle exists in a traveling direction, where the suspected obstacle protrudes beyond an edge of a rack; determining a relative position relationship between the suspected obstacle and a target position that the robot is required to reach along a current traveling direction when the suspected obstacle exists in the traveling direction; determining that the suspected obstacle is an obstacle when the suspected obstacle is located between a current position of the robot and the target position; and replanning a traveling route to avoid the obstacle.

A vehicle for an automated storage and retrieval system is configured to follow a route relative to tracks of the automated storage and retrieval system. The route includes one or more track crossings. The vehicle includes a first set of wheels capable of moving the vehicle in a first direction; a second set of wheels capable of moving the vehicle in a second direction perpendicular to the first direction; and one or more sensors attached to the vehicle and configured to detect the one or more track crossings while the vehicle is moving in the first direction or the second direction.

Provided is a doffing scheduling method and apparatus for yarn spindle product, and storage medium, applied in an automatic doffing system, relating to the field of computer technology, and particularly to the field of automation control. The automatic doffing system is connected to an automated guided vehicle, (AGV) and an overhead rail doffing vehicle, the AGV and the overhead rail doffing vehicle being deployed in different vertical spaces within a target workshop. The method includes: determining a target doffing vehicle corresponding to a first winding machine in the target workshop from the AGV and the overhead rail doffing vehicle based on time-related information of doffing the yarn spindle product in all or part of winding machines in the target workshop; scheduling the target doffing vehicle to complete a doffing task of the yarn spindle product in the first winding machine.

A method, control system and computer program for routing and rerouting of container handling vehicles handling storage containers in an automated storage and retrieval system comprising a framework structure forming a three-dimensional storage grid structure for storing the storage containers in storage columns, the framework structure including a grid-based rail system arranged above the storage columns with the rail system providing available routes for the container handling vehicles handling and transferring the storage containers to and from the storage columns, and wherein each container handling vehicle comprises a first set of wheels configured to move the vehicle along a first lateral direction (X) of the grid-based rail system and a second set of wheels configured to move the vehicle along a second lateral direction (Y) of the grid-based rail system, the second direction (Y) being perpendicular to the first direction (X), the movements of the container handling vehicles being controlled by a control system, that determines which tasks are to be done by specified container handling vehicles, destination locations for performing the tasks and which routes the container handling vehicles are to travel on the rail system. The method comprises the following steps performed by the control system when executing the computer program: running a multi-agent pathfinding algorithm, MAPF, in the control system for establishing and assigning routes on the rail system for the container handling vehicles from their current locations to assigned tasks at destination locations; determining how far the container handling vehicles can travel on a first part of the assigned routes within a set time interval, the first part being shorter than the assigned routes to the destinations; locking the first parts of the assigned routes that the container handling vehicles can travel within the set time interval; instructing the container handling vehicles to move from their current locations to an end location on the assigned locked routes; repeating steps above.

A physical space includes obstacles with different characteristics. Different sensors may detect some obstacles well, while other obstacles are poorly detected. An autonomous mobile device (AMD) uses data from various sensors to determine information about the physical space that is expressed in layers. Each layer represents specified areas within at least a portion of the physical space, with each area having a value representative of whether an obstacle is present. Some layers may represent specific volumes, or height ranges. For example, different layers may represent a low height, a medium height, and a high height. Aggregated data may be determined using the values from multiple layers. The aggregated data may be calculated using an aggregation profile to specify a relative weighting for the values in a particular layer. The aggregated data may then be processed to determine maps, such as a navigation map for autonomous movement, floorplan, and so forth.

A remotely operated vehicle includes an arrangement to provide a pre-alert and tracking of a vehicle following a travelling route relative to tracks laid out on rails. The vehicles have first and second sets of wheels connected to drives. The arrangement includes at least one sensor module provided with at least four sensors. A first sensor is directed vertically downwards to detect the rails in the x-direction, a second sensor is directed vertically downwards to detect the rails in the y-direction, a third sensor is positioned on the sensor module to detect a corner of an intersection between the rails in the x-direction and y-direction, and a fourth sensor is configured to detect a remaining distance to the arrival of the vehicle at a set position.
