Problems solved by technology

[0003] The control method of the manipulator is the key link in the robot control. The existing control methods of the manipulator mostly use the combination of images to model the manipulator or separately through the control panel. Control each joint, the implementation of these two control methods has many limitations, and there are certain technical defects
First, the control method of collecting the 3D image information of the scene through the camera, modeling the robotic arm, and allowing the robot to make autonomous decisions has relatively high requirements for the control algorithm, camera precision, and robotic arm, and this method is suitable for complex environments. Not applicable
Second, the control method of controlling the joints of the corresponding manipulator by rotating the knob on the control panel is simple and easy, but this method cannot realize the multi-axis linkage of the manipulator, and it is difficult to complete more complicated operations

Embodiment 1

[0058] like figure 1 As shown, this robot control system based on the master-slave teleoperation manipulator includes master manipulator and information acquisition board (1), monitoring center PC (2), robot main control board (3), slave manipulator and FPGA motion control board (4), on-site environmental information collection board (5). The monitoring center PC (2) is connected to the main mechanical arm and the information acquisition board (1), and the monitoring center PC (2) is connected to the robot main control board (3) through wireless network communication, and the robot main control board (3) is connected through the CAN bus From the mechanical arm and FPGA motion control board (4), on-site environmental information collection board (5).

[0059] The main mechanical arm and the information acquisition board (1) refer to the main arm manually operated by the operator in the system, and the acquisition board of the angle information of each joint of the main ...

Embodiment 2

[0062] like image 3 As shown, it is the operating field hardware platform, including the robot main control board, FPGA motion control board and sensor information acquisition board. As the main control module, the main control board is an ARM development board equipped with embedded Linux. The development board is equipped with a USB camera, a USB wireless network card, and a CAN bus controller MCP2510. The USB camera completes the job site video collection, and the USB wireless network card completes Through WIFI, it communicates with the monitoring center PC or on-site wireless router. The MCP2510 controller accesses the CAN bus through the CAN bus transceiver, and communicates with the two external modules. In the embedded Linux operating system, in addition to transplanting the camera driver and wireless network card driver, the open source video codec library xvidcore and the real-time transmission library jrtplib are also transplanted, which are responsible for vid...

Embodiment 3

[0085] like Image 6 , Figure 7 Shown is the experimental part of Experimental Example 2, that is, the functional verification part.

[0086] like Image 6 Shown is a screenshot of the control panel of the monitoring center written based on MFC. As shown in the figure, the control panel generally includes video display, control panel operation, sub-module operation, robot position display, on-site robot IP address input, sensor switch, on-site environmental information and vehicle body status display. After the communication is established, the operator can manually operate the master manipulator to complete the control of the slave manipulator, and the operation screen of the job site can be transmitted to the control panel through video. It can be displayed in the control panel in real time. The operator can also shut down parts such as the main control board, the sensor information acquisition board, and each sensor module as required.

Abstract

The invention discloses a robot control system and method based on a principal and subordinate teleoperation mechanical arm. The robot control system comprises a principal mechanical arm and information collection plate, a monitoring center PC, a robot principal control panel, a subordinate mechanical arm and FPGA movement control panel and a site environmental information collection plate. The robot control method includes the steps of principal mechanical arm manufacturing and data collection, the control of a subordinate mechanical arm, a trolley and a cradle head, video collection and communication of the robot principal control panel, data collection and communication of the site environmental information collection plate and data display and communication of the monitoring center PC. Under the condition that the complexity of a system is not added, the mechanical arm can be controlled to achieve relatively complex movement. A modularized mode is designed to be used, and modules are in communication through CAN buses. An FPGA is used as a movement control panel, establishing and updating of the system are convenient, and the stability of the system is improved. A robot transmits the video information of a working site and the environmental information of the working site to a monitoring center so that the robot can be controlled to complete more complex operations.

Description

technical field [0001] The invention belongs to the field of robot control, and in particular relates to a robot control system and method based on a master-slave teleoperation robot arm. Background technique [0002] In the past ten years, with the development of science and technology, robots have penetrated into various fields of production and life, and robot control methods have become a research hotspot in universities, enterprises and institutions. Robots can not only replace people in some more complex or repetitive tasks, but also reach places that people cannot reach or are more dangerous. With the continuous enhancement of the functions of robots, in some fields people can use robots to do work that they could not do before, and robots have even completely replaced the operations of workers. So far, with the assistance of surgical robots, many cases of transnational surgery have been completed around the world, bringing more hope to patients; in the Fukushima n...
