智能搬运机器人(论文16000字)
摘要：本文通过研究智能搬运机器人现状设计出一种基于单目摄像头识别物件并带有多自由度机械臂的智能搬运机器人。主要研究内容如下：首先上位机端简化了物件坐标的定位，采用二维平面坐标定位方式。并对二维码识别的Zbar算法进行优化，加快了二维码识别的速度。结合OpenCV算法库在Visual Studio编程软件中编写图像处理算法和机器人通信上位机界面。其次选取Ardunio控制器作为机器人的控制核心。DC直流减速电机和L298N型直流电机驱动器以及TCRT5000红外循迹模块，在控制程序作用下，实现行走转向。通信方面则采用ESP8266作为和上位机的通信工具。抓取则采用四个SG90舵机构成四自由度的机械臂实现对物体的抓取，并对机械臂的运动学进行分析，以便实现程序上对机械臂的准确控制。最后对整个系统进行搭建并对实物进行连接，经测试该智能搬运机器人系统实现了单目对物件的抓取与识别，简化了物件定位的计算，为单目机器人的抓取提供了新的思路。

Intelligent Handling Robot
Abstract：In this paper, an intelligent handling robot with multi-degree-of-freedom manipulator based on monocular camera is designed by studying the status quo of intelligent handling robot. The main research contents are as follows: Firstly, the upper computer simplifies the object coordinate positioning, and adopts the two-dimensional plane coordinate positioning method. The Zbar algorithm of two-dimensional code recognition is optimized to accelerate the speed of two-dimensional code recognition. Combining OpenCV algorithm library and Visual Studio programming software, image processing algorithm and upper computer interface of robot communication are compiled. Secondly, the Ardunio controller is selected as the control core of the robot. DC DC deceleration motor, L298N DC motor driver and TCRT5000 infrared tracking module can realize walking and steering under the control program. In the aspect of communication, ESP8266 is used as the communication tool with the host computer. Four SG90 rudder mechanisms are used to form a Four-Degree-of-Freedom manipulator to grasp the object, and the kinematics of the manipulator is analyzed in order to realize the accurate control of the manipulator in the program. Finally, the whole system is built and connected with the object. After testing, the intelligent handling robot system achieves monocular object capture and recognition, simplifies the calculation of object location, and provides a new idea for the capture of monocular robot.
