Design of AGV Training Scheme
This article through the design AGV practical cases, introduces the hardware design and the choose and buy mode; The main function of three kinds of control system are introduced, respectively is the ground (upper) control system, vehicle (single) control system and navigation/guidance system. This project is the coordination of the ministry of education co-operative education programs; Goal is to design a set of practical cases. Introduction AGV is automatic guided vehicles, is equipped with electromagnetic or optical automatic guiding device, such as can walk in accordance with the provisions of the direct route, which has the function of safety protection device and a device to run transport cars; Also called as a wheeled mobile robot.[1,2] AGV research and development about the computer, automatic control, information communication, mechanical design and electronic technology, and other disciplines, is a set of optical, mechanical and electrical and computer in the integration of new and high technology. Based on the development project of the AGV, make a able to independently identify the path of intelligent Vehicle, its design content covers the control, pattern recognition, sensing technology, automotive electronics, electrical, computer, machinery, energy, and other disciplines of knowledge, to student's knowledge and the ability to practice and the cultivation of good. This project based on the example as the goal, the AGV car to subdivide instance project for mechanical system design, circuit design, the driver software system development, the realization of the intelligent dispatching and obstacle avoidance algorithm, such as the car system overall debugging more child tasks, studying the role of students in each subtask, subtasks difficult problem, how to give students the right guidance method, etc., to help students in the process of project research and development, to solve the relevant problems in the design of step by step. By complete training project, so that the students can have a comprehensive understanding of the process of mechanical and electrical system of research and development, to involve the machinery, electronics, circuit, control, detection, each link of knowledge to autonomous learning, active learning, change the past passive learning approach to learning, to cultivate applied talents of high quality, cultivate and improve the students analysis solves the question ability, practical ability, team cooperation ability and innovative thinking ability cultivation of comprehensive ability. The System Structure First the overall design is modular, whether it is a vehicle carrying platform, using standardized interfaces, and all kinds of sensor module regardless of electromagnetic guided, optical guide, or visual (recognition) guidance, etc can be used.[3] Vehicle body slide platform is extensible, loading different tray, can carry different objects; Driving wheel travel mechanism adopts two rounds of differential, buy electric drive and integration power actuators, such as the iTAS servo actuator is made up of servo motor, low screw back lash planet reducer of a coupling of mechatronics device drivers. The system overall framework is shown in figure 1.
