Design of RFID-based weight sorting and transportation robot

摘要

Abstract This study investigates automatic sorting and handling robots to enhance intelligence and automation in logistics distribution, improve work efficiency, and reduce logistics costs. The kinematics and dynamics models of the sorting and handling robot are established by the study using single-chip microcomputer control technology. For automated item sorting, radio frequency identification (RFID) card scanning technology is combined and the PID control algorithm is examined. A single-chip microcomputer control technology is used to establish the robot’s kinematics and dynamics models and analyze the PID control algorithm. Employing RFID card reading technology facilitates the transportation and automatic sorting of items. The MATLAB software simulates PID parameters and assesses the stability of PID-controlled motors. The primary controller samples and provides feedback from the motor encoder every 10 ms. Setting the left and right motor encoder’s given values to 40 with a corresponding speed of 40, we observe that Option 1’s P parameter is too small, leading to a slow adjustment speed. In contrast, Option 1’s parameters are extensive. Scheme 3’s P parameter is too large, risking system oscillation. After carefully adjusting and selecting Scheme 2, experimental verification demonstrates the sorting and handling robot’s stable operation, achieving the anticipated effect.
