An articulated robot is one of the most common and versatile types of industrial robots, widely used in manufacturing and automation. It is typically designed to resemble a human arm, with multiple joints that allow flexible and precise movement in three-dimensional space.
Core definition
An articulated robot is a robotic system that uses rotary joints (axes) to move its arm segments, giving it a high degree of flexibility and range of motion.
These joints (also called degrees of freedom) allow the robot to bend, rotate, and position its end tool in almost any direction, similar to how a human shoulder, elbow, and wrist function.
Structure of an articulated robot
An articulated robot is made up of several key components:
Base – The fixed or mobile foundation of the robot
Arm segments (links) – Connected mechanical sections
Joints (axes) – Rotary points that enable movement
Wrist assembly – Provides orientation and fine positioning
End effector – Tool attached at the end (gripper, welder, etc.)
Most industrial articulated robots have 4 to 6 axes, although advanced models can have more for increased flexibility.
How articulated robots work
Each joint is powered by motors and controlled by a central system. By coordinating the movement of all joints, the robot can:
Move in complex paths
Reach into tight or hard-to-access spaces
Precisely position tools or parts
This coordinated motion creates a large, spherical work envelope, allowing the robot to operate in complex 3D environments.
Key characteristics
1. High flexibility
Articulated robots can move in many directions and orientations, making them suitable for complex tasks.
2. Multiple degrees of freedom
More joints mean greater movement capability and precision.
3. Human-like motion
Their structure mimics a human arm, enabling natural and efficient movement patterns.
4. High precision and repeatability
They can perform the same task repeatedly with consistent accuracy.
5. Wide working range
They can reach around obstacles and operate in confined spaces.
Common applications
Articulated robots are used across many industries, including:
Welding (arc, spot, MIG/TIG)
Assembly operations
Material handling and machine tending
Painting and coating
Packaging and palletizing
Inspection and quality control
They are especially dominant in automotive and manufacturing environments due to their versatility.
Advantages
