What Are Articulated Robots?

Articulated robots are sophisticated mechanical systems designed to mimic the flexibility and range of motion of a human arm. Unlike their rigid counterparts, these robots feature multiple rotary joints (typically 4-7 axes) connected by links, allowing them to perform complex movements with remarkable precision.

Anatomy of an Articulated Robot

The design of an articulated robot can be broken down into several key components:

1. Base: The foundation that anchors the robot to the ground or mounting surface.
2. Rotary Joints (Axes): The connection points between links that allow for rotational movement.
3. Links/Arms: The rigid structures connecting the joints.
4. End Effector: The “hand” of the robot, customized for specific tasks (gripper, welder, spray gun, etc.).
5. Controller: The brain that coordinates movement and executes programmed instructions.
6. Servo Motors: The muscles that power joint movement with precise control.

“The true power of articulated robots lies in their versatility,” explains Dr. James Wilson, Professor of Robotics Engineering at MIT. “With their human-like range of motion, they can adapt to an incredible variety of tasks that would be impossible for other robot configurations.”

How They Differ From Other Robot Types

While industrial robotics encompasses various designs, articulated robots stand apart due to their distinctive jointed structure. Here’s how they compare to other common robot types:

• SCARA Robots: Faster but with more limited range of motion; better for simple pick-and-place operations
• Cartesian Robots: More precise for linear movements but less adaptable to complex environments
• Delta Robots: Superior speed for light payload sorting but limited workspace and payload capacity
• Collaborative Robots: Similar structure but designed specifically for safe human interaction

The Evolution of Articulated Robots: From Past to Present

The journey of articulated robots began in the early 1960s with the development of the first programmable robotic arm, Unimate, which was deployed at a General Motors factory in 1961. This pioneering invention handled dangerous die-casting tasks, marking the beginning of industrial robotics.

Fast forward to today, and articulated robots have undergone remarkable transformations. Modern versions feature advanced sensors, AI-powered vision systems, and sophisticated control algorithms that enable them to work with unprecedented precision and adaptability.

“When I started in this field 25 years ago, programming a robot to pick up an irregularly shaped object was a major challenge,” recalls Maria Chen, Chief Robotics Officer at AutoTech Industries. “Today’s articulated robots can identify objects, calculate optimal grip points, and adjust on the fly—all within milliseconds.”
