[Answer] Is Industrial Robotics Hard to Learn? Can You Teach Yourself Without Formal Training?

The concept of industrial robotics is quite broad. Some parts are difficult, while others are not, so they need to be discussed separately.

From the perspective of application alone, industrial robots are not especially hard to work with. If you use the products of a specific manufacturer, most of the core functions are already packaged and implemented. What is mainly required is to adapt and tune the system according to the actual project scenario, and to design or fabricate the necessary peripheral components.

To give a concrete example, suppose you want to build a typical industrial robot palletizing project. Whether you use ABB, KUKA, FANUC, Yaskawa, or any other major brand, there will usually be supporting robot design software available. For ABB, for example, I believe the software is called RobotStudio. In general, there are also standard solution templates for common applications.

For a system integrator, the job is to select the right robot model based on factors such as the size and weight of the products to be palletized, as well as the required cycle time. The integrator also needs to design the supporting equipment that the robot manufacturer does not provide, including the power distribution system, fixtures and tooling, rails, fences, brackets, and so on. Finally, the robot must be programmed and debugged. This part can either be done by the manufacturer for you, which is usually very expensive, or completed independently.

Based on the general process above, which is only a very rough illustration, if you want to learn industrial robot applications, project experience and hands-on practice are essential. Of course, there are online tutorials on robot programming and debugging that can help, but this is ultimately a very practical, engineering-oriented skill, so it is best to have real projects to work on.

Generally speaking, I would recommend starting with one of the "big four" robot brands and focusing on just one at the beginning. As the saying goes, once you understand one, the others become much easier. After you have learned one system well, switching to another brand is mostly a matter of becoming familiar with a different product line and software environment.

As for the crucial opportunity to gain practical experience, one option is to take a short-term vocational training course. Once you have a basic foundation, two or three months of hands-on training is usually enough to become reasonably familiar with the work. Another option is to find a company willing to take you on as an intern or assistant engineer, and trade entry-level pay and labor for practical training opportunities, if such an opportunity is available. In short, much like driving or operating CNC machine tools, industrial robot application work is not that hard to master at the practical level. As long as you have the chance to practice, you can pick it up fairly quickly.

Now let me briefly talk about the harder side, though my own knowledge here is limited. Several key components of industrial robots are servo motors and drives, reducers or gearboxes (planetary or harmonic), and motion path planning. These three areas are absolute trade secrets for robot manufacturers. The hardest part is not the basic principles themselves, but the fact that they depend on a combination of precision manufacturing, materials science, computer science, mathematics, and other foundational sciences and applied technologies. Reaching, let alone surpassing, the current top manufacturers is by no means easy. Even for those leading companies, making further breakthroughs is still very difficult.

Therefore, if you want to engage in theoretical research or product development in industrial robotics, that path will be highly challenging and demanding. Naturally, it is also extremely difficult.
