Embodiment Construction

[0007] The present invention will be described in further detail below.

[0008] The cafeteria service robot obtains the scene of the front section of the road through the camera installed at the front end, recognizes the position of the tracking line and the stop line, and controls the rotation of the steering gear so that the tracking line is located in the middle of the image captured by the camera, that is, the left and right axes of the robot Facing the track line to ensure that the robot can drive along the track line. In order to ensure that the robot can achieve a stable tracking effect at the turn, the rotation angle of the steering gear is controlled by closed-loop control. The single-chip microcomputer calculates the angle error of the steering gear according to the deviation between the position of the identified tracking line and the middle position of the image, uses the PID control algorithm to calculate the control rate, and controls the rotation of the steerin...

Abstract

The invention belongs to the field of a service robot, in particular to the service robot for a cafeteria. The middle position on a front end of the robot is provided with a camera for tracking; a tracking line is overlaid on a cafeteria path or a pass-through path; and a stop line is overlaid vertical to the tracing line in a dining area. When the robot identifies the stop line, the robot stops for 10 seconds, and countdown display is carried out on a liquid crystal display (LCD) display; two rear wheels serve as driving wheels to form speed closed-loop control; a steering engine for controlling front wheels to steer forms position closed-loop control; and two sides of the robot are provided with surface plate trays connected with a direct-current motor shaft to form the position closed-loop control. The service robot has the advantages of simple structure and low cost and is stable to operate, the function of sending and fetching food and tableware can be effectively realized, and the management level of the cafeteria and the operation automation degree can be improved. The service robot for the cafeteria can be applied to service occasions, such as cafeterias and the like.

Description

technical field [0001] The invention belongs to the field of service robots, and relates to a service robot for a cafeteria, in particular to a service robot device with a tracking function. Background technique [0002] The food selection in the cafeteria needs to be selected by the diners, and the used plates need to be collected manually by the service staff. This situation increases the labor intensity of the service staff on the one hand, and on the other hand, the centralized selection of food by the diners increases the dining time of the diners. At the same time, the flow of people causes the restaurant to be crowded and affects the dining environment. Sometimes it will affect the service quality of the restaurant, resulting in a decrease in restaurant service satisfaction. [0003] Therefore, designing a restaurant service robot capable of tracking, delivering food for the diners, and realizing the self-cleaning of the dishes by the diners can effectively reduce th...
