What is a Collaborative Robot?
A collaborative robot (cobot) is a robot designed to work safely alongside humans in shared workspaces without protective barriers. Unlike traditional industrial robots that require safety cages, cobots use advanced sensors and built-in safety features to detect human presence and adjust their behavior accordingly.

What is a Collaborative Robot? Complete Definition
A collaborative robot (cobot) is a type of robot specifically designed and built to work safely in direct contact with humans in shared workspaces. The key word here is "collaborative" – these robots are meant to work with humans, not replace them entirely.
Here's what makes cobots different:
Safety first design: Cobots have built-in safety features like force sensors that make them stop immediately if they bump into a person. Traditional industrial robots can seriously hurt someone, but cobots are designed to be safe even during direct contact.
No cages needed: Unlike traditional factory robots that need protective barriers and safety fences, cobots can work right next to humans without any physical barriers.
Easy to program: You don't need to be a computer programmer to operate most cobots. Many can be "taught" by simply moving their arm to show them what to do.
Plug and play: Most cobots can be set up and running in just a few hours, not weeks like traditional industrial robots.
The term "cobot" was actually coined in 1996 by researchers at Northwestern University who won $50 in a naming contest. Today, cobots represent 10.5% of all robot installations globally and are the fastest-growing segment in robotics.
The Fascinating History of Cobots
The invention that started everything (1996)
The story of collaborative robots begins with a problem at General Motors in 1994. GM wanted robots that could work safely alongside humans without the massive safety cages that traditional robots required.
1996: The breakthrough moment – Two professors at Northwestern University, J. Edward Colgate and Michael Peshkin, invented the first "cobot" concept. A postdoctoral researcher named Brent Gillespie coined the term "cobot" and won $50 in a naming contest.
1999: First patent filed – US Patent 5,952,796 was issued on September 14, 1999, for "An apparatus and method for direct physical interaction between a person and a general purpose manipulator controlled by a computer."
Commercial breakthrough (2005-2008)
2005: Universal Robots founded by three University of Southern Denmark students (Esben Østergaard, Kristian Kassow, and Kasper Støy) in a small Denmark town.
2008: Game changer – Universal Robots launched the UR5, the world's first commercial collaborative robot capable of working safely alongside humans without safety caging. This robot was installed first at Linatex, a Danish supplier of technical plastics and rubber.
Market explosion (2010s-2020s)
2016: Safety standards established – ISO/TS 15066 specifications were published, containing guidelines for human worker safety in collaborative robotic systems.
2024: Market maturity – The cobot market reached $2.6 billion globally with over 57,000 units installed in 2023 alone, representing 31% year-over-year growth.
How Cobots Work: Technical Deep Dive
The brain: Advanced control systems
Modern cobots use safety-rated control systems that monitor every movement in real-time. These systems must comply with ISO 13849 (Performance Level) or IEC 62061 (Safety Integrity Level) standards.
What they monitor constantly:
Joint position and speed
Applied force and torque
Human presence and proximity
Environmental conditions
System health and diagnostics
The senses: Multiple sensor types
Joint torque sensors: Most common safety mechanism. Each joint has sensors that detect when the robot encounters unexpected resistance (like hitting a human).
Vision systems: 3D cameras and computer vision help cobots "see" their environment, identify objects, and detect human workers.
Force/torque sensors: Usually mounted in the robot's base or wrist, these sensors detect physical contact and measure applied forces.
Proximity sensors: Laser scanners, radar, and infrared sensors detect humans approaching the work area.
The safety net: Built-in protection
Power and force limiting: Cobots are designed with inherent limitations on how much force they can apply. If they contact a human, they immediately reduce power or stop completely.
Collision detection: Advanced algorithms analyze sensor data in real-time to detect collisions within milliseconds and trigger protective stops.
Compliant joints: Many cobots have "soft" joints that give way under pressure rather than continuing to push with full force.
Emergency stops: Multiple types of emergency stop systems can halt all robot motion instantly when activated.
Four Types of Collaborative Operations
The international safety standard ISO 10218 defines exactly four types of collaborative operations. Every cobot application must fit into one of these categories:
1. Safety-rated monitored stop (SRMS)
How it works: The robot stops all motion when a human enters the collaborative workspace, but power stays on so it can resume automatically when the area is clear.
Real-world example: A cobot at an assembly station stops when a worker approaches to inspect the product, then resumes once the worker steps back.
Detection methods: Safety scanners, light curtains, pressure mats, or vision systems detect human presence.
2. Hand guiding
How it works: The human operator physically guides the robot by touching it directly. The robot follows the human's movements smoothly and compliantly.
Real-world example: Teaching a cobot new waypoints by physically moving its arm to the desired positions, or manually guiding it to handle delicate objects.
Safety requirements: Must use safety-rated enabling devices that stop the robot if the operator lets go.
3. Speed and separation monitoring (SSM)
How it works: The robot continuously adjusts its speed based on how close humans are to it. It slows down as people get closer and can run at full speed when no one is around.
Real-world example: A cobot palletizing boxes runs fast when workers are far away but slows to safe speeds when someone approaches the work area.
Technology used: Laser scanners, radar, and 3D vision systems track human positions in real-time.
4. Power and force limiting (PFL)
How it works: The robot is designed so that contact between human and robot is expected and acceptable. It has built-in force limits that prevent injury.
Real-world example: A cobot working directly with a human to assemble products, where occasional contact is normal and safe.
Safety features: Joint torque sensors, current monitoring, and inherently safe lightweight design.

Common Myths Debunked
Myth 1: "Cobots are automatically safe"
Reality: Every cobot application requires individual risk assessment. The robot might be designed safely, but the application, end-effector, and workpiece can create hazards.
Why this matters: Companies have been injured assuming cobots are inherently safe without proper safety analysis.
Myth 2: "Cobots will eliminate all manufacturing jobs"
Reality: World Economic Forum data shows 97 million new jobs created vs. 85 million displaced by 2025. Cobots typically augment human workers rather than replace them entirely.
Supporting evidence: 13.7% of AI/robot-using firms increased workforce vs. 6.9% that decreased.
Myth 3: "Cobots are too expensive for small businesses"
Reality: Entry-level cobot systems start at $25,000-$40,000 with payback periods of 6-18 months. Many SMEs achieve ROI faster than large enterprises due to simpler operations.
Real example: B-Loony Ltd achieved ROI in 9 months and expanded production 5,000%.
Myth 4: "You need programming expertise to use cobots"
Reality: Most modern cobots use drag-and-drop programming or hand-guiding. Basic applications can be set up by operators with minimal technical training.
Training reality: Basic operator training takes 1-2 days, not months or years.
Myth 5: "Cobots can't do real industrial work"
Reality: Major manufacturers like Electrolux, Siemens, and DHL use thousands of cobots for critical production tasks with documented productivity gains of 15-68%.
Scale proof: DHL operates 7,500+ robots across 90% of their warehouses globally.
Myth 6: "Traditional robots are always better for high-volume production"
Reality: While traditional robots have advantages in speed and payload, cobots offer flexibility, easy changeovers, and lower total cost of ownership that can outweigh pure speed advantages in many applications.
Consideration factor: Changeover time, product mix variability, and space constraints often favor cobots even in high-volume scenarios.
