How to select a joint robot based on reach, payload, and repeatability

Oct. 22, 2025

Understanding the Importance of Reach in Robotics

1. Definition of Reach

Reach in a robotic arm is the maximum distance the end effector can extend from its base. It is crucial to ensure that the robot can access all necessary areas in your production line.

2. How to Calculate Required Reach

To determine the required reach:

  1. Identify the work area of the robotic arm.

  2. Measure the distances involved in your tasks.

  3. Calculate the maximum reach needed considering the robot\'s workspace.

Determining the Necessary Payload Capacity

1. Defining Payload

Payload refers to the maximum weight a robotic arm can handle. It is essential for ensuring that the robot can perform its tasks without failure.

2. Steps to Assess Required Payload

Follow these steps:

  1. List all components and tools the robot will handle.

  2. Calculate the total weight of these items.

  3. Add a safety margin to the total weight for reliability.

Evaluating Repeatability for Precision Operations

1. What is Repeatability?

Repeatability is the ability of a robot to return to a specific position consistently. High repeatability is essential for tasks requiring precision.

2. How to Measure Repeatability

To measure repeatability:

  1. Define the target positions the robot must achieve.

  2. Program the robot to move to these positions multiple times.

  3. Measure the deviation from the intended position on each attempt.

Choosing the Right Robot Model

1. Compare Robot Specifications

When selecting a model, compare:

  • Reach and payload capacity

  • Repeatability accuracy

  • Degrees of freedom

2. Understanding Robot Types

Familiarize yourself with common robot types:

  • Articulated robots

  • SCARA robots

  • Delta robots

Common Mistakes to Avoid When Selecting a Robot

1. Underestimating Reach Requirements

A common error is not accurately measuring the required reach, leading to operational inefficiency.

2. Neglecting Payload Needs

Focusing only on reach and not considering payload can result in selecting a robot that cannot handle the intended tasks.

3. Ignoring Environmental Factors

Make sure to consider the working environment—factors like temperature and humidity can impact robot performance.
