Design of the Control System for the Dining Service Robot on the Overhead Monorail

Service robot research has developed very rapidly in the recent few years, the restaurant service robot has been the most important part of the research. In this paper, a dining service robot working on the overhead monorail is designed to deliver food instead of waiters. The content of this dissertation involves the design and development of the control system of it, including hardware and software. It is composed of the main controller, DC motor driving module, RFID read-write positioning module, and signal gathering module. A control platform was developed to monitor the robot's running state and delivery status in real-time. And then, a two-layer fuzzy control algorithm was proposed to improve the motion control precision of the robot. The experimental results show that the dining service robot using this control system has the advantages of high positioning accuracy, fast response, and strong robustness.
