“Man vs. Machine?” – A plea for rethinking their collaboration

On the way to Industry 4.0 many people wonder: “Will machines substitute human workers?” Since its beginning, the fourth industrial revolution has been discussed alongside with this question. It is as old as automation itself; however, it looks at the winds of our times from the wrong perspective. It is not about “man VS machine”, but “man WITH machine”.

According to a study carried out by the International Federation of Robotics (IFR), the number of robots sold globally will have doubled to about 400,000 units by 2018. 70 per cent of total turnover is generated in China, Japan, USA, South Korea and Germany. Here are some figures to compare: South Korea employs 478 industrial robots per 10,000 employees, in Germany, this figure currently stands at 292 units. Of course, this number will not stay at 2.9 per cent robots among 10,000 employees, but even with this number going up, the density of robots dampens the widespread fear of losing one’s job.

Often, the fact that one industrial robot is not the same as another is being overlooked. One driving force behind growing sales on the automation market are collaborative robots in particular, so-called cobots. These lightweight robots were developed in order to combine the skills of man and machine perfectly. They are light-weight and can be deployed in multiple ways. Due to these robots being easily operated, they do not need to be programmed by expert programmers. This saves costs and thus makes the robots an easy tool for everybody.

Robots create jobs

For the Danish company Trelleborg Sealing Solutions, collaborative lightweight robot arms have become the basis of its growth. Approximately three years ago, Trelleborg implemented the first robot in its production, where ca. 100,000,000 sealings are being made annually. Now 38 collaborative UR5 robots and four UR10s increase the company’s profit. Because incoming orders sky-rocketed, the company was able to hire 50 additional employees despite the new robots. Thanks to the robots, one single employee can operate a cell of eight CNC-machines simultaneously. Without the robots, he could only operate a maximum of three machines. The robots created more jobs, because the orders on hand were increased notably.

A similar development could be observed at FME Feinmechanik AG in Switzerland. “Due to the prejudice that jobs are lost to the integration of robots, I refused to implement robots for a long time”, says Marco Bortolan, CEO and proprietor of the company. However, today, his company and in particular his employees benefit from the integration of collaborative lightweight robots into the production cycle. Productivity has been increased significantly and contrary to widespread fears of lay-offs, the company was able to hire one additional employee. The robot arms affect the work routine of each individual employee of the production in a positive way, taking over physically strenuous jobs while feeing up the workers to concentrate on other tasks. The employees consider the physical relieve as well as the saving of time as the greatest added value.

Collaborative And Safe Automation With Collaborative Robots From Ur

Automation changes the type of work humans do

The result of this rung-in change is intended to be that man and machine respectively do what they can do best. The weaknesses of one are compensated for by the strengths of the other. When lightweight robots assume repetitive or ergonomically unfavorable tasks, illnesses linked to the job decrease and the workplace becomes safer.

Therefore, Tegra Medical, the American producer of medical devices decided to automate their processes using cobots. Today, three collaborative robots are employed in the production of medical devices. These cobots work right next to humans without additional safety guarding and have resulted in a doubling of production throughput. The collaborative U10 robot with a reach of 51” enables Tegra to produce three different products in a single machining cycle. Moreover, resources of eleven employees were set free and can now be used for tasks with higher value creation.

The mass phenomenon automation

There is certainly no lack of possibilities to be employed for cobots. There is only a lack of imaginative power and acceptance to consider automation more as a chance rather than a risk. The machines are intelligent, react adaptively and adjust themselves to new situations and production processes. Factory halls will not yet become deserted.

Esben H. Østergaard is Chief Technology Officer at Universal Robots and is responsible for the enhancement of existing UR robots and the development of new products. He holds a Ph.D. in Robotics.

Esben H. Østergaard is one of the inventors behind the UR robots. During his years from 2001 – 2005 as researcher and assistant professor in robotics and user interfaces at University of Southern Denmark, he created the foundation for a reinvention of the industrial robot. In 2005, this led him to found Universal Robots together with two of his research colleagues. Since then, Universal Robots has taken about 30 patents on the technology of the robot. Besides his work as CTO, Esben H. Østergaard is participating in national research projects and he is also an external examiner at several universities in Denmark.

Earlier in his career, he worked as research scientist at USC Robotics Labs in Southern California and also at AIST in Tokyo as a visiting researcher. During his studies in Computer Science, Physics and Multimedia at Aarhus University in Denmark, he focused exclusively on robotics and became world champion in his hobby; robot football in 1998
