A Deep Dive into Industrial Robots: What Does Each Type Do?
Types of Industrial Robots: What Are They?
Industrial robots can be categorized in various ways—based on motion structure, application, or control systems. However, the most common classification is by mechanical structure, which includes the following main types:
1. Articulated Robot
Features multiple joints (typically 4–6 axes or more), with motion similar to a human arm.
Best for: Welding, painting, material handling, part assembly
Pros: Highly flexible, great for 3D movement
Cons: Expensive, requires complex programming
2. Cartesian Robot (Gantry Robot)
Moves in three linear axes (X, Y, Z) along straight rails.
Best for: Pick & place tasks, CNC machining, 3D printing, material transfer
Pros: High precision, easy to program
Cons: Requires a lot of space, limited directional movement
3. SCARA Robot (Selective Compliance Assembly Robot Arm)
Operates with horizontal and vertical movements. Known for high speed and rigidity.
Best for: Electronics assembly, soldering, product inspection
Pros: Fast and precise, ideal for automated production lines
Cons: Limited range of motion in certain directions
4. Delta Robot
Has a triangular arm structure and extremely fast movement capabilities.
Best for: Sorting, packaging, picking lightweight items like food or small parts
Pros: Fastest type among all robots
Cons: Not suitable for heavy-duty tasks
5. Cylindrical Robot
Moves in a circular and vertical motion along a cylindrical axis.
Best for: Assembly, welding, machine loading
Pros: Easy movement in confined spaces
Cons: Less popular in modern applications
6. Collaborative Robot (Cobot)
Designed to work safely alongside humans without safety fences.
Best for: Tasks involving human interaction such as loading, inspection, packaging
Pros: Safe, user-friendly, simple programming
Cons: Lower power compared to traditional industrial robots, not suited for heavy work
✅ Summary: Industrial Robots Come in Many Types
To choose the right robot, consider:
- Type of task
- Installation space
- Required speed and accuracy
- Budget
Choosing the right robot for your application can make your production faster, more cost-efficient, and improve product quality.
