Today, in many new applications, man and machine work hand in hand, and both contribute to production with their own unique capabilities. The interaction and cooperation of robots and cobots, which are the determining components of Industry 4.0, which has become a main framework that shapes the strategies and investments of institutions today, increases the efficiency and stimulates the competition. So, what are the differences between robots and cobots, the heroes of automation systems? Which processes become more efficient with which type. What should small or large companies pay attention to when making their choices? Are cobots open to intuitive use that can work with humans by eliminating the security fence, or robots with high transport and high speed capabilities that work with high security measures in autonomous areas?
Main difference: Security procedures
Since robots and humans do not always work in the same environment for security reasons, cobots developed to help people in certain processes can work safely in the same environment with humans. The speeds of the cobots can be optimized to prevent damage in the event of any collision in line with the determined ISO standards. They constantly detect force precisely with force sensors on the axes and bodies of the cobots, so they react faster in case of any contact and do not harm people. Robots, on the other hand, work in applications that require high speed production, surrounded by security fences or in a closed environment. Robots, which receive instant torque information through motors, can cause minor damage to themselves and their surroundings in the event of a collision, therefore robot work cells are designed by taking the necessary safety measures.
What does your production track need?
Another difference between robots and cobots is related to their carrying capacity. Since the carrying capacity and application areas of cobots are more limited, robots have more usage areas. The capacity of a FANUC robot ranges from 0.5kg to 2300kg, while the highest capacity FANUC cobots are on the scale from 4kg to 35kg. For example, when a 50 kg part needs to be transported, since no solution can be found with cobots, it is necessary to design the same project with robots. However, if the carrying capacity and cycle times are suitable, the use of cobot provides space advantage. On the other hand, if the cobots and people are not constantly working in the same area in the relevant process, the cycle time of the cobot can be accelerated by an area scanner. To give an example based on application areas; While robots are used in main production lines due to cycle time and capacity in welding, painting and transportation processes, cobots come to the fore in assembly, masticating, low capacity transportation and human assistance processes.
Adapt your choice to your process
Global trends in the world is changing very quickly and almost said looking for ways to be robotized all sectors Fanuc Turkey General Manager Teoman Alper Yigit robotic Umeda weight is in the automotive industry, the second row of white goods and metal industry, after the food, pharmaceutical, chemical mean that such sectors come. Yigit noted: "most demanding robots welding robots in Turkey. The reason for this is that too many robots are used in the automotive and automotive supply industry. In the second row we can put the handling robots used in the general industry - that is, robots that place a product from one place to another - in the third row we can put the robots that serve a little bit larger and serve at the end of the line in the form of palletizing robots. However, the new trend is for cobots working with humans. Cobots can be considered as new applications, robot and human cooperation, and the increasing need for physical spaces in factories, has been very popular recently. Cobots, which we define as collaborative robots, serve a great need thanks to their ability to work with humans by removing the security fence in today's technology. Cobots, which can be easily used by small and medium-sized businesses or businesses that have recently switched to automation, offer great advantages in terms of quality and repeatability, as they control their power much more precisely than humans. It provides great convenience for users with little programming experience with intuitive use. Whether robots or cobots are more advantageous is all about the processes applied. It is not right to make a judgment that one is superior to the other or more efficient. " - Hibya
