Six Advantages of Industrial Robots From a Technical Point of View

1. Generality


Industrial robots can be programmed for which they support the movement with multiple degrees of freedom; therefore, their application is quite flexible. Of course, they are not as flexible as human beings; however, industrial robots are far more flexible than many of the dedicated machines that are commonly seen in industrial automation. During the modification for the industrial application, they can meet the new demand through the re-programming for the robots, there is no need to make a large amount of investment on hardware.


2. Electromechanical properties

It is common for the industrial robots to reach the movement precision of less than 0.1mm, they can capture the objects with the weight of hundreds of kilograms, and they can extend with the length of three to four meters. Although they cannot achieve the processing requirements for mobile phones in a skillful way, for most of the industrial applications, this kind of property is enough to complete the task in a perfect way. With the gradual improvement of performance for the robots, some impossible tasks before are gradually becoming feasible (for example, laser welding or cutting once required the special equipment with high precision to guide the direction of laser, with the improvement of precision for robots, we can also rely on the accurate movement of robots themselves for the replacement).



3. The corporation between human and machine

The traditional industrial robots are working inside a cage, they are separated from the humans because they are very dangerous (imagine that someone captures something of several tens or several hundred kilograms and swings with the speed of four meters per second, I believe that no one is willing to approach it). The main reason is that ordinary robots will not be integrated with additional sensors for the detection of special circumstances outside based on the consideration of cost and technology, quite silly, they will only follow the programs compiled by human beings for the movement day by day unless there is an external signal which tells them to stop. Therefore, the common method is to prepare a cage for the robots, when the door of the cage is open, the robots will stop when they receive the signal. With the consideration of safety, it is natural to bring more additional cost for the integration of robots, the cage may not be so expensive, but we have to carefully consider the layout of the production line, increase the area of the production line and change the cooperation method between humans and machines for it so that we can influence the efficiency of production. From the angle of industrial demand, we have met the demand of automation such as the precision, speed, and weight through the traditional industrial robots, it is time for us to meet the safe cooperation between human and machine.

4. Accessibility

The nature of work for traditional robots is to continuously follow the route points one by one, in the meantime of receiving or setting the I/O signals outside (to cooperate with other settings such as clamping apparatus and transport lines etc.). While the process for the guide of robots to do so is the programming of robots. The programming applied by the enterprises of traditional industrial robots themselves has become the separation wall between the costs of technology and integration technology.


Of course, it has already been considered for the intuitiveness and simplicity of programming in the industry, but there has not been any practical development for the purpose of business besides the display of concept again and again from traditional manufacturers (such as the utilization of the exoskeleton, 3D image, virtual reality etc.) for which people are wary of the keywords “simple programming” as soon as they hear it.


As a latecomer, industrial robots should dare to challenge and make some achievements and be the selling point that is recognized by the public. The disruptive technology is not likely to be successful in the leading enterprises, but it is usually developed by the challengers who come later. Because leaders are very likely to be far away from their permanent employment for each of the steps further on the disruptive technology since the resistance from both inside and outside is great.


No matter how the accessibility of robots has gained the attention of the public, how to let the operators command the robots well like playing their mobile phones without any (or excessive) training has become the direction of manufacturers for the large investment.


5. Cost

The cost of industrial robots can be as small as 5000 USD for small models and as large as hundreds of thousands USD in large scale. Naturally, this cost is lower than the high-end professional manufacturing equipment. From the angle of degree for the popularity of robots in the industrial field of the west and the domestic manufacturing industry in recent years, it is indicated that the economic advantage of automation has commonly reached a critical point which exceeds other methods of replacement (manual, or dedicated machine), it seems that the cost is worthwhile


6. Intelligence

Relative to the mainstream demand of the current market for robots (that is strong, fast and accurate), it is temporally not the most urgent issue. It also explains the advantages of traditional industrial robots (work without complaints, guarantee the quality and quantity, be a good worker) and insufficiency (still clumsy, require humans for the guidance).


That does not mean that intelligence is not important, on the contrary, enterprises have started to make technology investment. For example, how to let the robots better understand the intentions of humans and relatively self-directed to understand and plan for the tasks instead of waiting for humans for the procedures step by step; how to let robots automatically adapt to the variation of the external environments (the dim light may impact the identification of image, special treatment may be required for the damaged articles on the conveyor belt); how to judge the assembly quality of the components through the sense of touch, sight and hearing and so on and so forth.



In general, the popularity of industrial robots is the inevitable trend of social development, no one can resist it. The large amount of simple type of work in production requires no humans for which humans are freed from the simple and repeated work; they can develop more creative work.
