Talking about the difference between robot teaching programming and offline programming

With the rapid advancement of science and technology, industrial robots have become an important part of today's industrial production, and it can perform a variety of tasks and operations with great precision. They have a wider application space than human limitations. Robot technology has been proposed for about 50 to 60 years. After the 1970s, with the development of computers, robots were widely used in industrial production. With the wide application of robots, robot technology has been extended and applied to various fields from a single industrial production, and a number of robots have been applied to the fields of construction, medical treatment and flight.

After the 1990s, due to the rapid development of artificial intelligence, mechatronics and computer technology and sensor technology, robot technology has taken a new step. Therefore, robot technology will develop along the trend of intelligence and complexity.

Simply put, a robot is a mechanical device that can automatically execute a program and complete a work. It can work through a preset program, or communicate with a human being through a communication device to complete a predetermined task.

Since the intelligent development of robots is a big trend, then we have to talk about how robots are programmed for how it does its intended work.

First of all, the robot programming is an action sequence program that is manually written for the robot to automatically perform an operation task. Depending on the type of robot controller and the complexity of the chip, it can usually be programmed in a number of ways. There are two common ways to program robots:

The first is manual teaching programming, that is, the operator manually controls the joint motion of the robot through the teach pendant to move the robot to a predetermined position, and simultaneously records the position and transmits it to the robot controller, after which the robot The task can be automatically repeated according to the command, and the operator can also select different coordinate systems to teach the robot. The following is a teaching programming picture found from the Internet. I saw a little sweat and a sweat. It seems that in order to teach programming, I have to lose weight immediately, and then practice squats, splits, or simply practice. Yoga is good~

Then talk about the teaching device, the teaching devices of each robot can be described as varied, the operation is not the same, or the smart phone is now good, Apple and Android are unified. Below is a picture of some of the teaching devices that Xiaomeng found from the Internet to share with everyone who wants to learn robot programming.

This is just a part of the teachings of Xiaomeng. When I saw them, I couldn’t help but sigh. Even if Xiaomeng is young and young, I have to learn them all. Xiao Meng to complete?

The above is a summary of the teaching programming, presumably everyone has a certain understanding of teaching programming, the following summarizes the drawbacks of teaching programming:

1. Teaching online programming process is cumbersome and inefficient.

2, the accuracy is completely determined by the visual inspection of the teacher, and it is difficult to achieve satisfactory results for the complicated path teaching online programming.

3. There are too many types of teaching devices, and the amount of learning is too large.

4, the teaching process is prone to accidents, but the equipment is damaged, but the person is injured.

5. Robots should be occupied when teaching actual robots.

Manual teaching programming is mentioned here first. The following is the second robot programming method that is offline programming.

Offline programming is a popular programming method. First, let's talk about offline programming. In Xiaomeng's view, the so-called teaching programming, because the teach pendant and the robot are connected by cable, and must be programmed at the job site. So it can be called online programming or live programming. Offline programming, as the name implies, is that there is no need for a noisy scene in the environment. This is a big gospel for Xiaomei’s little girl who loves beauty. It feels like a moment of going up, as if from Master Zhuo’s Modern Times. Into the American blockbuster "Avatar." Closer to home, offline programming is a three-dimensional virtual environment that rebuilds the entire working scene in the computer through software. Then the software can automatically generate the robot according to the size, shape and material of the part to be added and the operation of the software operator. Motion track, which is the control command. Off-line programming overcomes many of the shortcomings of online teaching programming, making full use of the functions of the computer, reducing the time cost of writing a robot program, and reducing the inconvenience of online teaching programming.

When it comes to offline programming, you have to talk about offline programming software. I mentioned that RobotArt, RobotMaster, RobotWorks, RobotStudio, etc., which everyone can hear here, are among the best in the offline programming industry. Take Beijing Airlines' RobotArt offline programming software as an example. Although this offline programming software is made in China, its company's technical background is the experience of several years of aerospace engineering of Beihang Robotics Research Institute and CAD Center, and the second is dozens of people. The excellent R & D team, so compared with RobotMaster, RobotWorks, RobotStudio, the function is not inferior, and has an aerospace background, is currently the top software in the domestic brand of offline programming software. The biggest feature of the software is that it automatically generates machining trajectories according to the shape of the parts in the virtual scene, and can control most mainstream robots. The support for domestic robots is also great! The software generates the robot motion trajectory according to the topological information of the geometric model, and then the trajectory simulation, the path optimization, and the post code are all in one go. At the same time, the collision detection, the scene rendering and the animation output are integrated, and the realistic simulation animation can be quickly generated. Widely used in grinding, deburring, welding, laser cutting, CNC machining and other fields. The following picture is an interface of this software:

To sum up, the advantages of this software are:

1. Support multi-format 3D CAD models, import extensions such as step, igs, stl, x_t, prt (UG), prt (ProE), CATPart, sldpart, etc.

2. Support offline programming operations of various brands of industrial robots, such as ABB, KUKA, Fanuc, Yaskawa, Staubli, KEBA series, Xinshida, wide number, etc.);

3. Has a large number of high-end aerospace application experience;

4. Automatically identify and search the CAD model for point, line, and surface information generation trajectories;

5. The trajectory is associated with the CAD model features, the model moves or deforms, and the trajectory changes automatically;

6. One-click optimization of collision detection between trajectory and geometric level;

7. Support a variety of process packages, such as cutting, welding, spraying, deburring, CNC machining;

8. Support the publishing of the entire workstation simulation animation to the web page and mobile phone;

However, this software does not support some small brand robots abroad.

The robot offline programming system is developing in an intelligent and specialized direction. The user operation is more and more simple and convenient, and the control program can be quickly generated. Parameterization can be implemented in some specific application areas, which greatly simplifies the user's operation. At the same time, robot offline programming technology has important significance for the promotion and application of robots and the improvement of work efficiency. Off-line programming can greatly save manufacturing time, realize real-time simulation of robots, and provide flexible working environment for robot programming and debugging. Programming is a big direction for robot development.
