How to Read the Table:
- The motion range indicates the available axes and the robot's kinematic type.
- Payload (example) indicates an approximate range, but remember that these values can vary significantly depending on the model.
- Speed/Cycle Time indicates how quickly the robot can perform a typical operation. The shorter the cycle time, the higher the productivity.
- Applications are examples of typical processes in which a given robot type is most commonly used.
This comparison makes it easier to decide which robot type meets your requirements for efficiency, payload, or precision. In the following sections, we will provide practical guidance on when a particular design is the best choice and when alternatives should be considered.
Discover six main factors influencing the decision to choose a particular robot type
When to Choose a Specific Design and When to Consider an Alternative
Every type of robot has strengths and limitations. Whether a given design is suitable for your plant depends on the specifics of your processes, expected performance, available budget, and environmental conditions. Below, we highlight six basic criteria that help explain the advantages and limitations of different designs:
Range of Motion and Flexibilit
Articulated robots provide versatile movement across multiple planes, but they can be more complex to program.
SCARA and Delta robots offer high speed with lighter loads, but have limited flexibility of movement along the vertical axis.
Payload and Reach
If you plan to handle heavy components, for example in the metal industry, an articulated or gantry robot may be necessary.
Delta and SCARA robots are ideal for lighter loads where short cycle times are important
Safety and Working with People
Cobots are the best choice when a robot needs to work directly with an employee.
In traditional designs, articulated robots,
SCARA) often requires a safety zone, such as guarding or sensors.
Ease of Programming and Integration
Cartesian robots (XYZ) can be simpler in trajectory configuration, which may accelerate implementation in linear processes.
In articulated and mobile robots, programming complexity may be higher, but they offer greater flexibility.
Purchase and Maintenance Costs
Simple designs, such as Cartesian robots, often have lower investment and operating costs.
Advanced robots, such as articulated models with high payloads, involve higher prices and longer payback periods but can handle complex tasks.
Working Environment and Industry Standards
In the food, chemical or pharmaceutical industry, a robot must meet strict hygiene and safety requirements (e.g. easy-to-clean housing, resistance to substances).
In heavy industry (metal, steel), resistance to high temperatures and dust, as well as the ability to operate in harsh conditions, are important.
When should you choose a specific type?
- Articulated Robots when you need movement flexibility and high payload capacity.
- SCARA/Delta - when speed and a short cycle time are crucial for light payloads.
- Cartesian - when you value simplicity and repeatability of movement along linear axes.
- Cobots - when safe collaboration with people in the same area is required.
- Mobile (AMR/AGV) - when the goal is automatic internal transport in a warehouse or production line.
Remember that the ideal choice also depends on the planned applications and the industry in which you operate. You can explore this by visiting the Industries or Robot Applications sections. If you have questions, we will be happy to advise you on selecting appropriate technologies and estimating return on investment.
Simple Tips to Help You Move Efficiently from Concept to Industrial Robot Launch
How to Match the Robot Type to Infrastructure and Needs
Even the best-selected type of robot may fail to deliver the expected results if implementation planning is carried out chaotically. Below are six key tips that will help you effectively match the robot type to your existing infrastructure and the specific needs of your company:
Detailed Process Analysis
- Identify which stages of production or logistics require the most manual work, generate high costs, or frequently cause errors.
- Consider whether one robot type is sufficient or whether different designs are needed in different areas.
Adaptation to Environmental Conditions
- Check the temperature, humidity level, presence of dust, and exposure to chemicals.
- Make sure the selected robot, such as a Cartesian, articulated, or SCARA robot, has an appropriate protection rating or is resistant to aggressive environments.
Integration with Existing Systems
- Pay attention to compatibility with control systems such as PLC, MES and ERP, as well as communication standards such as OPC UA and Profinet.
- The better the robot works with current infrastructure, the easier process management and monitoring will be.
Development Plan and Scalability
- Consider whether you plan to expand production lines, change the product range, or add more workstations in the future.
- Choose a design, for example an articulated robot with reserve payload capacity, that will allow easy upgrades or the addition of further modules.
Safety and Work Zones
- Conventional robots often require guarding, light curtains or other protective systems.
- If close human-machine collaboration is important, consider cobots or additional safety systems tailored to your processes.
Well-Planned Logistics and Service
- Ensure sufficient space for potential inspections and maintenance.
- Check whether the supplier provides fast access to spare parts and after-sales support. This is essential for limiting downtime and maintaining production continuity
These guidelines will help you plan the implementation step by step while minimizing the risk of unexpected costs and delays. If you need an individual consultation, we will be happy to help develop a detailed automation strategy, from process analysis to robot integration with your system.

Frequently Asked Questions
Often yes, especially if you choose a universal multi-purpose robot or a design with flexible reach. In some cases, however, using different robots in different areas is more effective and helps achieve maximum efficiency.
It depends on production scale, labor costs and task type. ROI can often be achieved within 1-2 years, especially when automation significantly increases productivity.
Yes, provided they support the appropriate weight range and operate under conditions that meet hygiene requirements. If very short packaging cycle times are required, Delta robots are also worth considering.
Gentle product handling and fast packaging are usually important. Many companies choose Delta robots, SCARA robots, or cobots equipped with adaptive grippers.
Collaborative robots generally have lower payload and movement speed for safety reasons, but they can still significantly simplify many assembly or packaging tasks.
Fencing, motion sensors, light curtains, and emergency shutdown procedures are used. Everything depends on the risk assessment and applicable standards, such as ISO 10218.
