Abstract

The invention discloses a wheeled mobile robot, a control method and system thereof and a storage medium, and the control method comprises the steps: generating a global path according to key point information and a global static cost map; generating a local path by using a control point model according to the global path and a local dynamic cost map; generating the speed distribution of each point on the local path according to the local path and the motion constraint of the vehicle, and planning a reference trajectory; and calculating a control instruction according to the reference trajectory, the control point model and the state of the vehicle, and distributing and executing the control instruction. Through the embodiment of the invention, high-performance motion planning and control can be realized through small calculation amount on the control of the wheeled mobile robot, and the purposes of saving calculation resources, reducing the cost and meeting the actual requirements of customizable scenes are achieved.

Description

technical field [0001] The present invention relates to the field of mobile robots, in particular to a wheeled mobile robot and its control method, control system and storage medium. Background technique [0002] Currently, wheeled mobile robots are widely used for automated movement in warehouses. In the realization of the warehousing automation system, the mobile robot needs to cooperate with the scheduling system to complete the automation and intelligence of the entire warehousing. Due to the customizable characteristics of the warehouse system (the scene can be customized to be "simple", not as "complex" as in the natural environment), R&D personnel have a certain degree of freedom to design the operation map of the entire warehouse, and the scheduling system according to the task situation, Send mission instructions to the mobile robot, and the mobile robot will independently decide how to move to the destination and perform related actions according to the existing m...
