Design of control system of human-computer interactive agv robot using double photoelectric encoder positioning

In order to study the design functional requirements of robot control system, in this study, an automated guided vehicle (AGV) robot is proposed, which can complete the autonomous navigation and handling of objects. Based on the design idea of core board + bottom board, the power circuit, sensor signal acquisition circuit, drive control circuit, human-computer interaction module interface circuit and USB interface circuit are designed. The motion control algorithm based on double encoders is studied. Positioning is the premise of motion control, so the positioning algorithm based on double encoder is also derived. The results show that the motion control algorithm based on double encoders is verified by experiments, and the AGV robot control system designed meets the design functional requirements. In the experiment with the maximum speed of 1 m / s, the robot motion control effect is good, and the final positioning accuracy can reach within 2cm. It can be seen that the control system basically meets the design requirements, improves the dynamic response and greatly improves the positioning accuracy. © 2020, Cefin Publishing House.
