How To Improve The Effectiveness of Industrial Robots Essay

Abstract

This paper focuses on the improvement of the effectiveness of industrial robots. The two primary characteristics were selected: accuracy and repeatability. The primary framework that was used is Design of Experiment (DOE). It is dramatically different from the conventional trial and error approach which is used in other studies since it allows the researcher to make more accurate calculations and predictions. Several techniques were used on different stages of the research: screening design, surface design, surface plot, and optimization plot. It was determined that the error of accuracy can be reduced to 0.006 while repeatability can be reduced from 0.3 to 0.027. According to optimization plot, further improvement can be made: error of accuracy can be reduced to 0.005 while repeatability can be improved of 0.027 to 0.0079. Recommendations for further research were produced: the scholars are encouraged to pay more attention to acceleration, speed, payload, payload wrist.

The research which has been performed focused on the importance of accuracy and repeatability in the work of industrial robots. This information is extremely important in the contemporary work due to the wide use of industrial robots in different stages of production. In spite of the fact that technology is far from reaching the level when it could substitute the work of humans, it is beyond any doubt that the current advancements in science regarding accuracy and repeatability contribute to the development of industrial robots in general. The focus on these two particular characteristics was not random. Thus, it is argued that accuracy is extremely useful for an industrial robot due to the fact that this will enable it to be more useful in the manufacture and be more helpful in the production process. As for repeatability, one of the major applications of the robot is the monotonous work that people would like to avoid. So, repeatability will ensure that a robot will achieve the desired result every particular time.

The method that was used in the research focuses on the concept of Design of Experiment (DOE). This framework is particularly important since it enables the research for focus on the fundamental characteristics of the topics that are investigated, ultimately contributing to validity and reliability of the study. Given the fact that the development of technology that would improve the performance of the robots was among the primary goals, it is beyond any doubt that the engagement of this technology is extremely important. One should also keep in mind that the use of DOE signifies the rejection of the conventional trial and error method that would not only be more costly, but also more time-consuming. The research focused on saturated design, making sure the findings are delivered faster and they would be more accurate.

Screening design is an important part of the research. It was used in the early stages in order to set the right course for the study and collect the necessary amount of the information. It is acknowledged that there are some limitations of this framework, but they are balanced by the fact that it was used in the beginning of the research which would enable the researcher to correct the data afterward. Thus, with the help of screening design, it was determined that the error of accuracy would be identified as 0.006. Some might suggest that this level is insignificant and there is not need to take it into consideration. While it may be true that in some actions this level of accuracy will not be important since a potential error will not lead to terrible consequences. Nevertheless, it is suggested that this value should be as low as possible. That is why there is room for further improvement. Speaking of another characteristic that was mentioned above, namely repeatability, it was established that it could be improved from 0.3 to 0.027. As one can easily see, this improvement is slightly better than the one which was mentioned above. However, even the value of 0.027 should not be considered to be sufficient since there is always room for improvement.

Another technique that was used in the research is called surface design. Unlike the framework which was mentioned above, this one should be considered to be more advanced. Indeed, it may be somewhat more difficult and require more time and effort, but the accuracy of it is much better. That is why after screening design was used on the initial stage, the surface design was used in the advanced stages of the research. This was done deliberately in order to improve the data which was obtained in the course of the research. Thus, it was decided that P-value of the processes should be in the region of 0.05. This way it was possible to determine which processes should be improved as they were underperforming in one way or another. The reason why 0.05 was chosen as the threshold of P-value lies in the fact that it makes the differences statistically significant.

There was another useful technique used – surface plot. It is a complex technique of representation that uses the key factors as the values that are placed on X and Y axes and Z axis represents the change. While some may find it difficult to use, it is clear that this approach is particularly useful since it shows the potential for improvement. Another point that should be mentioned with this regard is that this technique relies on the visual information and presents points that may have been overlooked before. Other than being particularly representative, this technique also highlighted the best range where the characteristics can be improved, also presenting implications regarding this change. In other words, it was extremely helpful for the researcher to see how the data can be represented visually and if there is a realistic room for improvement. This contributed to the findings of the research.

One more technique was used in the course of the study. It is called optimization plot. This technique primarily focuses on the hypothetical improvement of particular methods outlining their potential. According to it, it is possible to improve accuracy from 0.006 to 0.005. Once again this change may not seem particularly significant, but in the long run, it opens new opportunities for the use of the industrial robots, contributing to their effectiveness. Speaking of repeatability, the improvement that can be achieved may even be more impression: optimization plot estimated that it is possible to change the value from 0.027 to 0.0079 which is an outstanding improvement, possibly leading to a great breakthrough.

The research in question also produced a series of recommendations that can be used when future studies are performed. Thus, Pareto chart was used to determine the characteristics that should be addressed by the researchers of the future. This is extremely useful since it will allow the scholars to avoid doing the same research all over again and focus on those characteristics which are most important for the success of the study. It was determined that the following characteristics should be addressed in great detail: acceleration, speed, payload, and payload wrist. In spite of the fact that this is not an exhaustive list of improvement that can be made, it is speculated that these are the characteristics that should be addressed in the first place.
