How can robot automation be implemented in practice?

Why the robot alone is not a solution

It is often assumed that a faster or more capable robot is the right solution. In practice, however, it is not the robot alone that decides, but the interplay of gripping technology, feed, vision and process design. A robust gripper is of little use if parts vary strongly in the feed. Even the best vision system only works reliably if lighting, part position and tolerances are aligned with the process.

For managers in production, this means: the first question is not which robot to use, but what performance the system must reliably deliver in serial operation. Cycle time, part variance, availability and quality requirements must be considered together. Only on this basis can one decide whether a simple handling solution is sufficient or a turnkey production facility is the more economical solution.

Which building blocks must work together?

We repeatedly see in projects that the best individual component does not necessarily yield the best overall facility. That is why Aerne Engineering AG combines robotics and handling solutions with vision and inspection systems and implements them as turnkey production facilities. This turns a technical idea into a line that remains usable in everyday operation.

Where vision and quality assurance make the difference

A vision system is much more than a camera. It detects the position, location or features of a component and provides this information to the automation process. This enables the robot to reliably pick up, align and feed parts to the next process step. Quality assurance has a different task: it checks whether the result meets the defined quality requirements and whether the part can be released for the further manufacturing process.

Especially for variants in parts or mixed lots, the interaction of both systems is decisive. Quality inspection should not take place only at the end of the process, but should be integrated as early as possible in the manufacturing flow. This allows errors to be detected early and rejects to be avoided rather than sorting out defective parts afterwards.

Things to pay particular attention to

The more parts vary in terms of position, tolerances or surface, the more important robust image processing and clearly defined test criteria become. Even small changes in lighting or contrast can affect recognition quality. An early feasibility check helps to consider such factors and design the system robust from the outset.

How does a sensible design process proceed?

A successful robot automation does not begin with selecting a robot but with a clearly defined production process. Only when requirements, constraints and automation sequence are fully understood can an economical and robust solution be developed.

Understand the process: Which steps should be automated? Where are today’s bottlenecks, quality problems or manual activities with optimization potential?
Capture parts and constraints: Part geometry, tolerances, quantities, production performance, autonomy, feeding and environmental conditions form the basis for the technical design.
Define the concept: Automation sequence, robot, gripping technology, vision, inspection systems and material flow are aligned to the process. This creates no isolated solutions but a functioning overall system.
Plan integration: Controls, interfaces, safety, usability and ease of maintenance are considered early so the system can reliably be integrated into the existing production.
Support implementation: During realization, design, software and commissioning are closely coordinated. Tests with real components and structured optimization ensure the system meets the required performance in production.

From our experience, the biggest challenges rarely lie in the mechanics but in the interfaces between design, control and production process. If these are considered early and developed together, later adjustments, delays and unnecessary costs can be significantly reduced. Therefore, Aerne Engineering AG accompanies automation projects from the first feasibility study through engineering to commissioning and beyond.

Frequently asked questions

When is robot automation worthwhile at all?

Robot automation is especially worthwhile for recurring processes that take a lot of time, are error-prone or difficult to staff reliably due to the shortage of skilled workers. It becomes particularly economical when quantities, variants and quality requirements are clearly defined. If the conditions are still unclear, a feasibility study provides the necessary decision basis.

Why is a standard robot often not sufficient?

A standard robot only handles movement. It is the interaction with gripping technology, feed, vision, quality assurance and control that makes it a functional automation solution. The greatest engineering effort is usually not in the robot itself but in system integration.

When is a vision system necessary?

A vision system is required when parts arrive in different orientations, variants are processed or quality features must be inspected automatically. It enables reliable part recognition, supports process safety and reduces misgrips and manual interventions.

What is the most common planning mistake?

The most common mistake is looking at individual components in isolation. A suitable robot alone does not guarantee stable production if gripping, feed, vision or test concepts are not coordinated. Successful automation projects always start with the production process and not with the selection of individual components.

Robot automation achieves its full potential only when planned as a complete system. Those who consider robots, gripping technology, vision, quality assurance and process flow from the outset create the foundation for stable processes, short cycle times and consistently high production quality. This is precisely the difference between an installed facility and an automation solution that reliably operates in daily production.

If you want to modernize an existing production line or implement a new automation solution, the first step is a structured analysis of your process. Aerne Engineering AG accompanies you from feasibility study through engineering to commissioning and beyond. Together we develop a solution that is technically convincing and economically viable in the long term.
