And Why They Are Costly in the Medium and Long Term
Cobots are sometimes presented as a simple, fast, and inexpensive solution for automation. In practice, many companies discover after implementation that a cobot does not always meet expectations. Not because the technology is poor, but because of planning and understanding errors made in the early stages. Below are the most common mistakes in cobot implementation and how they affect business and technological outcomes.
Mistake Number 1: Choosing a Cobot Simply Because “It Is Safe”
One of the most common mistakes is the assumption that a cobot is the right choice simply because it is “safe” for working near humans. In practice, cobot safety is achieved through strict limitations on speed, force, and acceleration. This means lower throughput, longer cycle times, and sometimes direct impact on the ability to meet production targets.
Many companies discover too late that high safety comes at the expense of performance, and that a cobot also requires safety planning, risk assessment, and sometimes even partial guarding.
Mistake Number 2: Underestimating Safety Standard Requirements
There is a misconception that a cobot “operates without standards.” In practice, cobots are subject to stringent safety standards, primarily ISO 10218 and ISO/TS 15066. These standards define clear limits for forces, pressures, and speeds, and require professional testing and risk assessments.
When this is not planned in advance, projects stall, expensive modifications are required, or the cobot operates at speeds much lower than expected.
Mistake Number 3: Expecting a Cobot to Replace an Industrial Robot
Cobots are not a replacement for industrial robots. They are designed for relatively simple applications, with low loads and limited speeds. Attempting to operate a cobot in applications requiring high speed, long-term precision, or continuous operation across multiple shifts leads to wear, malfunctions, and sometimes disappointment with the investment.
In many cases, an industrial robot with proper safety planning would have delivered better, faster, and more cost-effective results.
Mistake Number 4: Focusing Only on Acquisition Cost
Cobots are perceived as an inexpensive solution, but the acquisition cost is only a small part of the picture. When examining actual throughput, cycle times, speed limitations, and the need for additional adjustments, the total cost over time may be higher than expected.
Companies that do not examine true ROI discover that the cobot does not generate the planned savings and sometimes even becomes a “bottleneck” in the production line.
Mistake Number 5: Ignoring Long-Term Planning
A cobot may be suitable for the initial stage, but what happens when production grows? When higher speeds are required? When the number of shifts increases? In many cases, a cobot chosen without future consideration limits growth and requires early replacement of the entire system.
Automation planning must consider not only current needs but also business development for years ahead.
Mistake Number 6: Lack of Understanding of Reliability and Durability Limitations
Many cobots are designed for relatively light environments. In real industrial settings—dust, heat, vibration, and continuous operation—they do not always provide the same level of reliability and durability as dedicated industrial robots. When this is not taken into account, a gap emerges between expectations and operational reality.
So When Is a Cobot Suitable?
Despite all the above, cobots can certainly be the right solution in certain cases:
- Simple and uncomplicated applications
- Low production volumes
- Environments where it is difficult to install guarding
- Small companies or Proof of Concept stages
The problem is not the cobot itself, but its incorrect use.
The Bottom Line
Cobots are an important tool in the automation world, but they are not a magic solution. Common mistakes in cobot implementation usually stem from a partial understanding of their safety, performance, and reliability limitations.
Companies seeking speed, high throughput, stability, and full control over the years should seriously consider industrial robot solutions with professional safety planning.
Good automation begins with the right decision—not the most popular choice.
Implementing automation is a professional and strategic decision, and it is therefore important to carry it out with proper guidance.
