Path planning method and device applied to service robot and service robot

The invention relates to the field of service robots, in particular to a path planning method and device applied to a service robot, the service robot and a storage medium. The method comprises the following steps: acquiring environment information of a target object and first state information of the target object; based on the environment information and the first state information, utilizing a trained Markov decision process model to obtain a first motion trend prediction result of the target object; and based on the environment information and the first state information, utilizing a social force model to obtain a second motion trend prediction result of the target object, fusing the first motion trend prediction result and the second motion trend prediction result to obtain a third motion trend prediction result; and based on the third motion trend prediction result, determining an optimal planning path, and executing a corresponding guide instruction. The method has the beneficial effects that the servi
