Cobot vs. Articulated Industrial Robot: Which Is Right for Thai SMEs? A comparison guide to Collaborative Robots (Cobots) and Articulated Industrial Robots
Explore the key advantages, limitations, and selection criteria to help Thai small and medium-sized enterprises (SMEs) choose the right robot for their manufacturing processes.
One of the most common questions from Thai SME manufacturers starting their automation journey is: "Should we choose a Cobot or an Articulated Industrial Robot?" There is no one-size-fits-all answer, because the two types are engineered to solve different problems.
In recent years, Collaborative Robots, or Cobots, have attracted increasing interest from small and medium-sized manufacturers due to their flexible installation options, user-friendly programming features, and ability to be designed for operation in close proximity to people under defined safety conditions. Meanwhile, Articulated Industrial Robots, such as the YASKAWA MOTOMAN GP Series, remain well suited to applications requiring high speed, precision, and payload capacity according to the specifications of each model.
This article compares Cobots and Articulated Industrial Robots across key criteria and provides practical guidance to help Thai SMEs select the right solution for their production needs.
🔹 What Is a Cobot (Collaborative Robot)? A Cobot, or Collaborative Robot, is a robot designed to support collaboration between humans and robots. A system can be designed to allow people and robots to operate in the same workspace under appropriate safety conditions and protective measures. However, not every Cobot application can operate without a safety fence. The need for protective measures must be determined through a risk assessment of the complete system.
Key features of Cobots:
• Built-in Force Sensors: Force-sensing or collision-detection functions that can trigger a stop or other protective response when contact or an obstruction is detected.
• Lightweight and easy to relocate: Can be redeployed between lines without major structural changes
• Hand Guiding programming: Teach it by physically moving the arm along the desired path — no coding required
• Payload: 10–30 kg
• Applications: Pick & Place, Assembly, Machine Tending, Inspection, and Packaging, particularly where production processes need to be changed frequently.
🔹 What Is an Articulated Industrial Robot? An Articulated Industrial Robot is a robotic arm with multiple joints. Six-axis articulated robots are widely used in industrial manufacturing and are designed for applications requiring speed, precision, and a range of payload capacities. One example is the YASKAWA MOTOMAN GP Series.
In practical applications, these robots are often installed with safety fences or other protective systems, depending on the results of the risk assessment, to ensure safe operation within the production environment.
Key features of Articulated Industrial Robots:
• High-speed operation: Suitable for applications requiring short cycle times and continuous production, depending on the robot model and task.
• Repeatability: 0.01–0.1 mm
• Durability: Engineered to run 24/7 in harsh industrial environments
• High payload capacity: 4–700 kg (MOTOMAN GP700)
• Applications: Welding, Assembly, Pick & Place, Palletizing, Painting, Press Tending, Part Transfer, Material Handling, and high-volume production.

Note: Specifications vary by model, manufacturer, application, and project scope. Always verify the specifications for the intended application.
🔹 When Should You Choose a Cobot? A Cobot may be suitable for an SME with the following requirements:
• Limited installation space: No area to build a fenced safety cell
• Human–Robot Collaboration: For example, a robot assists with picking and placing components while an operator performs assembly tasks nearby
• Light payload: Workpieces under 30 kg
• Frequent product changes: Low-Volume High-Mix or short-run production
• No dedicated engineering team: General workers can be trained in 1–2 days
🔹 When Should You Choose an Articulated Industrial Robot? An Articulated Industrial Robot may be more suitable for applications with the following requirements:
• Short cycle times: High-speed work such as mass production
• Heavy payloads: Applications include lifting automotive components, stacking boxes on pallets, or handling large metal parts.
• Long reach: Jobs needing 2–3 metres of reach, such as welding large vehicle bodies
• 24/7 operation in harsh environments: Dust, heat, or chemical exposure
• Dedicated engineering/technical team: Able to program and maintain the robot
• Sufficient space for a robot cell: The facility can accommodate the robot, peripheral equipment, workpieces, and required safety systems
• High-precision applications: Electronics, high-tolerance parts

❓ FAQ – Frequently Asked Questions about Cobots vs Articulated Industrial Robots
Are cobots really safe? Can they work near people without a fence?
• Cobots are designed to ISO/TS 15066, with force sensors in every joint that stop motion the moment they contact a person or obstacle. However, a Risk Assessment is always required based on the work and the End-Effector in use. If the tool involves blades, lasers, or other sharp instruments, additional safety measures may be needed.
Can cobots and industrial robots work together on the same line?
• Yes. Yes, and many modern factories do exactly that — for example, a MOTOMAN AR performs welding inside a fenced cell while an HC cobot feeds parts into the cell or removes finished parts afterwards.
How many cobot models does Yaskawa offer, and what is the maximum payload?
• YASKAWA's HC Series includes models such as HC10DTP, HC10DTFP, HC20DTP, and HC30PL with HC30PL has a maximum payload of 30 kg., which is among the highest in cobot.
