What Are Collaborative Robots (Cobots)?
Collaborative robots, commonly known as cobots, are robots designed to physically interact with humans in a shared workspace, without the need for protective fencing or isolation.
Unlike conventional industrial robots, which are typically large, powerful, and confined to gated cells for safety, cobots are built to:
- Detect and limit force in real time
- Move at safe speeds around people
- Pause or stop when unexpected contact is made
- Be programmed without coding—often by hand guidance
Cobots are not about high-speed, heavy-duty automation. They’re about safe, flexible, and human-centric automation.
A Brief History of Cobots
The term “collaborative robot” was first introduced in the mid-1990s, when researchers began developing machines that could safely assist people in industrial tasks. Since then, cobots have evolved into a mainstream automation category—especially for:
- Small to medium-sized enterprises (SMEs)
- Manufacturers with high-mix, low-volume production
- Facilities where humans and robots need to share the same station
Key Features That Define a Cobot:
- Power and Force Limiting: Sensors measure joint torque to stop movement if resistance (like a human arm) is detected.
- Hand Guiding / Teach Mode: Operators can physically move the arm to teach motion paths without coding.
- Safety-Rated Monitored Stop: Cobot halts when a human enters its working area.
- Speed and Separation Monitoring: Reduces speed when a human approaches; resumes when clear.
Did You Know?
Cobots make up the fastest-growing segment of industrial robotics, with global adoption increasing across electronics, medical devices, automotive, and logistics.
How Do Collaborative Robots Work?
Cobots are built with one mission in mind—safe collaboration between humans and machines. Their operation depends on a tightly integrated system of smart sensors, advanced control algorithms, and built-in safety features that allow them to function without cages or fencing.
Let’s break down the technology that makes cobots different from traditional robots.
1. Force and Torque Sensing
Every cobot is equipped with joint torque sensors or force sensors that continuously measure how much resistance the robot encounters during movement.
What It Does:
If the robot collides with an obstacle (like a human arm or torso), it immediately recognizes the abnormal resistance and stops the motion within milliseconds.
This feature is known as Power and Force Limiting (PFL)—and it’s the foundation of safe human-robot collaboration.
2. Smart Motion Control
Cobots use advanced motion control algorithms to ensure:
- Smooth, non-jerky movements
- Controlled acceleration and deceleration
- Limitations on speed and force based on proximity to people
They follow predictable, intentional motion paths, reducing the chance of sudden surprises for nearby human coworkers.
3. Safety Monitoring Systems
Cobots follow strict safety standards set by:
- ISO 10218-1 and 10218-2: Safety requirements for industrial robots
- ISO/TS 15066: Specific guidelines for collaborative robot safety, including permissible force thresholds and contact pressure levels
Built-in Safety Features:
- Emergency stop buttons
- Speed limitation modes
- Area scanners and proximity sensors
- Collision detection and auto-stop functionality
4. Programming Interfaces: Hand-Guiding & No-Code Teaching
Most cobots are designed for intuitive, hands-on programming. You don’t need to write complex code.
How it works:
- Manually move the cobot arm to the desired location
- The system “learns” and stores the movement path
- Fine-tune position or speed via a simple touchscreen or tablet interface
This approach—known as teach-by-demonstration—makes cobots ideal for non-technical users, including factory operators, warehouse personnel, and first-time automation users.
5. Vision System Integration
Cobots often integrate with:
- 2D/3D cameras
- Barcode scanners
- Object recognition systems
This allows them to:
- Identify parts of varying shapes/sizes
- Adjust grip orientation
- Perform quality inspection or sorting without extra programming
Result: Smarter decision-making, dynamic part handling, and minimal downtime between product changeovers.
6. Controlled Operating Speeds
Cobots operate at intentionally slower speeds than traditional robots, especially in shared workspaces. Their typical speeds range from:
- 250 to 1500 mm/sec, depending on proximity to humans
- Faster when in full isolation mode (with safety zones enforced)
The speed is dynamically adjusted using speed and separation monitoring—slowing down as humans approach and resuming normal speed once the area is clear.
Summary: What Makes a Cobot Collaborative?
