Discover Which Automation Technologies Work Best for Specific Processes
How to Match Robots to Specific Applications
Choosing the right type of robot depends not only on the industry but also on the specific tasks it must perform. Sometimes precision and repeatability are crucial, while in other cases high speed, payload, or operation under varied environmental conditions matters most. That is why we prepared the "Technology Selection by Application" guide, which explains how to match robots to processes such as assembly, welding, packaging, or handling heavy loads.
Whether you are interested in a versatile multi-purpose robot or a specialized design, such as a SCARA robot for high-speed operations, an articulated robot for welding, or a mobile robot for internal transport, here you will learn what to consider when planning a deployment and how to avoid common mistakes. We use an approach based on practical criteria such as component weight, working environment, and required motion precision so that you can easily assess which robot types can deliver optimal results in your processes.

Six Criteria That Will Help You Select the Robot Best Suited to Your Processes
Payload, Precision, Cycle Time, and Environmental Conditions
Once you have determined which tasks you want to automate, such as assembly, welding, packaging, or handling, it is time to analyze the technical requirements. Below we present six key criteria that will help you choose a robot suited to the specific parameters of your processes:
Payload and Reach
If you move heavy components (e.g. in the metal industry), choose a robot with a sufficiently high payload (e.g. an articulated robot with a reserve of several dozen kilograms).
In industries such as electronics or food, where products are lighter, Delta or SCARA robots with faster cycle times may be a better choice
Required Precision and Repeatability
In the electronics or cosmetics industry, where micrometer-level accuracy matters, robots providing high motion repeatability, such as SCARA robots or collaborative robots for small-part assembly, will be crucial.
High-payload articulated robots may have slightly greater deviation, which remains fully acceptable in most industrial applications.
Cycle Time and Motion Dynamics
On high-throughput production lines, such as packaging small food products, shorter cycle time means higher productivity.
Delta and SCARA robots often lead in the speed of pick and place operations, while welding applications may prioritize stability and continuity of articulated motion.
Working Environment (Temperature, Humidity, Dust)
In the metal or construction industry, a robot should be resistant to dust, high temperatures, and dusty environments, often requiring IP65-rated sealing or higher.
In pharmaceutical and food applications, anti-corrosion coatings that are easy to disinfect and resistant to chemicals may be required.
Compatibility with Machines and IT Systems
Check whether the robot has a controller with an open communication protocol, such as OPC UA or Profinet, to enable integration with MES, ERP, or WMS systems.
For assembly or machine-related tasks, such as operating presses or injection molding machines, robot movements must be synchronized with existing equipment.
Safety and Standards Requirements
Depending on the nature of the task, specific occupational safety, hygiene, or industry standards may apply, such as ATEX in potentially explosive environments.
If the robot is to work in direct contact with people, consider collaborative designs (cobots) equipped with force sensors and advanced collision detection systems.
These six criteria form the foundation for detailed analysis of technical requirements. Once they are defined, it becomes easier to select a robot type, such as articulated, SCARA, Delta, Cartesian, collaborative or mobile, and plan the next implementation steps. In the following sections, we will present a comparison table and discuss potential outcomes from selecting specific solutions without requiring detailed case studies.
