Development and Algorithm Design of Transportation Countermeasure Robot System

In response to the design requirements and competition rules of the “8th Zhejiang College Student Robot Competition”, we independently developed a set of robot systems. The system takes the STM32F103RCT6 microcontroller as the core, controls the motor and the robotic arm, and realizes the functions of moving, grabbing and placing. Equipped with seven-way and single-channel grayscale sensors to ensure straight line inspection, intersection detection and accurate positioning. The software part covers the robot's motion control, robotic arm control, robot flexible start and stop, path planning and design algorithms, the PID algorithm is used to achieve the precise control of the robot, and the A * algorithm is used for the simplest path planning. Based on the research of game theory, five sets of schemes were designed, and the matrix keyboard was designed to realize the choice of different strategies in the game. The test experiment results show that the ranking competition is about 50 seconds, and the stability of the robot is found to be higher than 95%, the robot system has been applied to the eighth college student robot competition in Zhejiang Province, through a round of ranking competition, three rounds of group stage and two rounds of knockout competition, and finally won the second prize of Zhejiang Province, which also shows that the five sets of strategies are effective and feasible. The transportation robot has a series of advantages such as low cost and strong scalability, which can provide reference for various robot competitions and related practical projects for college students. At the same time, we also put forward effective solutions to a series of problems encountered in the process of practice.
