The application relates to the technical field of robots, and provides a path finding method and device and a storage medium. The path finding method is applied to computing equipment in a path finding system. The path finding system comprises camera equipment, a mobile service robot and the computing equipment. The method comprises the following steps: acquiring a monitoring video shot by the camera equipment; determining the position of the mobile service robot in the shooting range of the camera equipment according to the monitoring video; planning a service path of the mobile service robotaccording to the position of the mobile service robot; and transmitting a path planning result to the mobile service robot, so that the mobile service robot finds the path in a path planning mode according to the path planning result. Through adoption of the method, the problem that the mobile service robot cannot take service area coverage and algorithm difficulty into account in the prior art can be solved.

The invention provides a gesture recognition method applied to the control of a mobile service robot for helping the elderly and the disabled. The combination of static gesture recognition and dynamic gesture recognition can eliminate the interference caused by complex background, large-area skin color or occlusion during gesture segmentation, and has natural The friendly human-computer interaction method, applied to the mobile service robot interaction system based on gesture recognition, can quickly and accurately recognize gesture commands and safely control wheelchairs, increase the range of activities of users, and effectively improve their quality of life.

The invention provides a control method for an intelligent mobile service robot based on head posture recognition. The method uses a constrained local model algorithm to detect facial feature points, and then uses the geometric relationship of facial feature points to estimate the current head posture, so that patients can Use the head to control the movement of the intelligent mobile service robot. Its specific implementation includes the following steps: training head posture samples to obtain facial feature point shape templates and local templates of feature points; using Kinect to collect head images and find facial positions; detecting facial feature points by constrained local model algorithms; Use the detected feature points to estimate the current head pose; then send different control commands to the mobile service robot according to different head pose parameters. By using the method of the invention, the handicapped persons can also stably control the intelligent mobile service robot by using the head, which facilitates their travel.

The invention aims to provide a wheeled mobile service robot. The wheeled mobile service robot comprises a chassis mechanism, a rack, a big arm mechanism, a small arm mechanism and a wire pulling motor component, wherein the small arm mechanism is connected with the big arm mechanism; the big arm mechanism is connected with the rack; the wire pulling motor component is arranged in the rack; the rack is fixed to the chassis mechanism; the small arm mechanism comprises fingers, a finger box, steel wire ropes, U-shaped frames, a servo turntable, a small arm worm wheel, a small arm worm, a small arm shell, a small arm motor and a wrist shell, wherein the fingers are arranged on the finger box; the U-shaped frames are arranged in the fingers; pins are arranged on the U-shaped frames; one end of each steel wire rope is fixed to each U-shaped frame; and the other end of each steel wire rope is connected with the wire pulling motor component; the finger box is arranged on the servo turntable; the servo turntable rotates automatically under the action of gravity and is connected with the wrist shell; the small arm motor, the small arm worm and the small arm worm wheel are arranged in the small arm shell and are connected in sequence; and the small arm worm wheel is connected with the wrist shell. The wheeled mobile service robot can not only perform single-arm independent work, but also perform double-arm cooperation.

The invention relates to the technical field of robots and provides a cooperative control method and device for multiple mobile service robots and a storage medium. The cooperative control method comprises the steps of: receiving a service request which is sent by a target control terminal and used for requesting the dispatch of a mobile service robot by a server; querying whether a mobile servicerobot in the idle state exists in a sub-area to which the target control terminal belongs or not by the server; if not, storing the service request in a waiting queue corresponding to the sub-area towhich the target control terminal belongs by the server; re-dividing a service area every preset time period to obtain a plurality of updated sub-areas by the server; for each updated sub-area, adding the service request sent by the control terminal located in the sub-area to the waiting queue corresponding to the sub-area by the server; and for each sub-area, allocating a mobile service robot tothe sub-area according to the number of service requests in the waiting queue corresponding to the sub-area by the server.
