便攜移動機(jī)器人操作機(jī)械臂與控制研究
[Abstract]:With the development of robot technology, as a branch of robot, the research of manipulator control technology has become a hot research topic of robot technology. In order to accomplish the operation and control task of the remote manipulator, the structure design and simulation of the mobile manipulator body are completed, and the mobile manipulator control system based on QNX is designed. The operator can accomplish the assigned task through the teleoperation control of the manipulator. In this paper, the control system of manipulator is designed and implemented on the platform of QNX real time operating system and C language. The control system not only meets the control requirements of the manipulator, but also has a wide range of versatility. After changing the control object, the new control requirements can be satisfied with only a small amount of modification. In this paper, the design configuration, modeling, hardware and software design of mobile manipulator are studied. Firstly, the design of mechanical configuration of manipulator and the derivation of kinematics equation are completed, and the inverse kinematics simulation of manipulator is completed. The shortest path is taken as the research goal in trajectory planning and the simulation results show that the algorithm is fast. High accuracy, meet the real-time requirements. Secondly, the hardware design of the control system is studied, the function and realization of each hardware part of the system are analyzed in detail, the communication network structure of the system is designed, and the working mode of each network is determined according to the communication requirement. Finally, the software design scheme of the control system is studied. On the basis of introducing the characteristics of the QNX system, the overall design scheme of the control system software is expounded, and then the multithread processing characteristics of the QNX system are analyzed. The multi-thread structure of the control system is designed, and the priority and scheduling strategy of each thread is set according to the task characteristics of each thread. The experimental results show that the design has successfully completed the purpose of the experiment and achieved the expected control goal.
