Choosing the Right Industrial Robot: Key Factors You Need to Know
Choosing an industrial robot can be more complicated than it looks. Many manufacturers invest heavily in automation only to discover that the Robot Does not provide enough payload capacity, cannot reach the required workstation, or fails to meet the accuracy requirements of the production process.
Choosing a robot based on price or specifications alone can lead to costly mistakes.
In this guide, we explain the key factors manufacturers should consider when selecting an industrial robot, helping you choose the right solution for your application from the very beginning.
01. Application and Robot Type: Start with the Right Structure
The first step in robot selection is not checking specifications. It is understanding what you need the robot to do.
Different applications require differenT Robot structures:
SCARA / 4-Axis Robots | 6-Axis Articulated Robots | Collaborative Robots | Delta Robots |
| Ideal for high-speed planar applications such as:
SCARA robots offer fast cycle times and good cost efficiency for these applications. | Suitable for more complex applications that require greater flexibility, including:
With six axes of movement, articulated robots can handle a wider range of working orientations and complex production tasks. | Collaborative robots are suitable for applications involving human-robot interaction, semi-automated production lines, frequent product changeovers, and low-volume/high-mix manufacturing. | Delta robots are designed for high-speed picking and placing of small and lightweight products, making them suitable for fast sorting and handling applications. |
Choosing the wrong robot type can limit performance, regardless of how good the specifications look.
Start by matching the robot structure to your application, then evaluate the detailed specifications.
02. Payload: One of the Most Important Selection Factors
Payload is the maximum load a robot can carry within its specified working space.
However, choosing a robot with the highest possible payload is not necessarily the best solution.
An oversized robot may increase both the initial investment and energy consumption. The goal is to select a robot with a payload capacity that accurately matches the actual application requirements.
When calculating payload, manufacturers should consider not only the workpiece but also the weight of the tooling, gripper, fixtures, and other equipment mounted on the robot.
The right payload is not the biggest payload—it is the payload that matches your application.

03. Axes, Reach and Repeatability
Even if the payload is correct, the robot may still be unsuitable if it cannot reach the required workstation or cannot achieve the necessary movement within a limited working area.
Three important specifications should be evaluated:
Working Reach | Robot reach determines the maximum area the robot can access. During selection, measure the actual distance from the robot installation position to the furthest workstation and leave sufficient operating clearance. A robot that technically reaches the target position but operates at the limit of its working envelope may not provide the desired flexibility or performance. |
Number of Axes | The number of axes determines the robot's movement flexibility.
|
Repeatability | Repeatability should be selected according to the actual process requirements rather than simply choosing the highest specification available. For example, the original application guidelines indicate approximately:
It is also important to understand that repeatability is not the same as absolute accuracy. Actual process accuracy can also be affected by factors such as incoming-part positioning, fixture rigidity, and the overall production setup. |
04. FANCHENG ROBOT: From Robot Selection to Long-Term Maintenance
Selecting the right robot is only the beginning of a successful automation project. Long-term technical support and maintenance are equally important.

The group has served more than 25,000 customers across various industries.
Don't Overlook After-Sales Support
When purchasing an industrial robot, the initial equipment cost is only one part of the investment.
Manufacturers should also consider whether the supplier can provide long-term technical support, including:
-
Robot installation and commissioning
-
Maintenance and repair
-
Spare parts supply
-
Technical troubleshooting
-
Ongoing equipment support
Reliable after-sales service can help maintain stable robot operation and reduce unexpected production downtime.
