Collaborative robots, more commonly known as cobots, are reshaping industries by working safely right alongside people. Unlike traditional robots that are locked away in cages, these machines are designed for direct human interaction, blending the best of human ingenuity with robotic precision. This guide breaks down everything you need to know about the world of collaborative robots, from their history and benefits to the safety features that make them trusted partners on the factory floor and beyond.
A collaborative robot is a robot specifically designed to physically interact with humans in a shared workspace. Instead of being separated by safety fences, cobots use advanced sensors and software to operate safely around people. The International Organization for Standardization (ISO) defines collaborative robotics as any automated system that can share a workspace with human workers as part of its operation. This new generation of robots can slow down or stop when a person gets too close, and many feature force limited designs so they cannot harm a worker if a collision occurs. In short, collaborative robots are fenceless automation solutions built for teamwork.
The idea of robots and humans working together is relatively new. Until the mid 1990s, industrial robots were powerful, caged machines designed to keep people at a distance.
The concept of collaborative robots originated around 1996 at Northwestern University. Professors J. Edward Colgate and Michael Peshkin partnered with General Motors to create a robot that could act as a smart assistant on an assembly line, enhancing a worker’s abilities without posing a threat. They coined the term “cobot” to capture this new idea of collaboration. Their first prototypes were unpowered, with the human providing the force and the robot providing the computer guided direction for safe movement.
The technology moved from concept to commercial reality in the 2000s. In 2008, a Danish company named Universal Robots launched the UR5, a small and affordable collaborative robotic arm. The UR5 made automation accessible to businesses of all sizes, not just large corporations. Around the same time, Rethink Robotics introduced Baxter, a two armed cobot with a friendly user interface designed to work next to factory employees. While these early models paved the way, the market truly took off in the mid 2010s as nearly every major robot manufacturer introduced their own collaborative robots. Adoption has grown rapidly since, with cobots accounting for about 10.5% of all industrial robots installed worldwide in 2023. For a deeper dive into adoption stories, see our case study.
Cobots have become popular for several key reasons, especially for small and medium sized companies looking to automate for the first time.

While they may look similar, collaborative robots and traditional industrial robots are designed for fundamentally different purposes.
The biggest difference is human interaction. Industrial robots are powerful and fast, so they must be kept inside safety cages to protect workers. Cobots, however, are built with force limiting sensors and other features that make direct contact with people safe. Essentially, industrial robots replace humans, while collaborative robots work with them.
To ensure safety, cobots typically operate at slower speeds and handle lighter payloads than industrial robots. Many cobots have payload capacities between 3 and 15 kilograms, while industrial robots can lift hundreds of kilograms. This makes cobots unsuitable for high speed, heavy duty tasks, but perfect for applications where traditional robots would be overkill.
Collaborative robots are designed to be easy to program and deploy. Many feature intuitive interfaces and allow for programming by demonstration, which means an existing technician can learn to manage them without needing to be a robotics expert. Industrial robots often require specialized programming knowledge and complex integration. To connect predictions and workflows with your existing stack, check out our integrations.
Safety is the cornerstone of collaborative robot design. They use several built in features to ensure they are human friendly.
One of the biggest selling points for collaborative robots is their incredible flexibility. Unlike traditional robots that are fixed in one place for years, cobots are designed to be easily moved and repurposed.
Their lightweight design makes it possible to mount them on carts and wheel them to different workstations as needed. Programming is also fast and intuitive, often done through a simple tablet interface or by physically guiding the robot’s arm. This means a cobot can be reprogrammed for a new task in minutes or hours, not weeks. This adaptability makes collaborative robots ideal for businesses where product lines change frequently.
Collaborative robots are being used in a growing number of industries. Manufacturing was an early adopter, with the automotive, electronics, and consumer goods sectors leading the way. Common applications include:
Beyond the factory, cobots are appearing in logistics for packaging, in laboratories for handling samples, and even in the service industry for tasks like preparing coffee. If you operate in online retail or fulfillment, explore our eCommerce solution.
Collaborative robots have made automation accessible for many businesses that previously found it too expensive. This is due to a few factors. First, the upfront cost of the robot itself is often lower than a traditional industrial model. Second, and more significantly, cobots generally do not require expensive safety infrastructure like fences and light curtains. This alone can save tens of thousands of dollars and valuable floor space. Finally, the fast and easy integration process means fewer engineering hours and less production downtime are needed to get a cobot up and running.
The ROI for collaborative robots is famously fast, often measured in months instead of years. Many users report a full payback period of 12 months or less. One industry analysis even found an average payback of just 195 days, or about six and a half months. These quick returns are driven by immediate productivity gains, reduced labor costs, and improved product quality. Even a payback period of two years is considered fast for capital equipment, making collaborative robots a financially attractive investment.
To ensure safety, the design and deployment of collaborative robots are governed by specific international standards. The foundational standard is ISO 10218, which covers safety requirements for industrial robots.
Building on that, ISO/TS 15066 is a key technical specification published in 2016 specifically for collaborative robot systems. It provides detailed guidance on designing a collaborative workspace that reduces risks to people. This includes defining the four distinct collaboration modes (safety rated monitored stops, hand guiding, speed and separation monitoring, and power and force limiting) and even providing data on pain thresholds for different parts of the human body to help set safe force limits. These standards ensure that cobots can be deployed without traditional safety cages, as long as a proper risk assessment is performed.
The field of collaborative robotics is evolving quickly, with several key trends shaping its future.
The cobot market is experiencing explosive growth. One report projects the global market for collaborative robots will reach approximately $18 billion by 2030, which reflects a compound annual growth rate of over 40% per year. This growth is driven by falling prices and a growing awareness of the benefits cobots offer, particularly for small and medium sized businesses. Larger teams can align on long‑range bets with our enterprise solution.
These trends point toward a future where collaborative robots are more capable, easier to use, and integrated into an even wider variety of workplaces.

The main advantage is their ability to work safely alongside humans without safety fences. This makes them flexible, easy to deploy, and suitable for tasks that require both human and robotic input.
Cobots are designed with multiple safety features like force limiting and proximity sensors. However, a full risk assessment of the specific application, including the tool at the end of the arm and the workpiece, is still required to ensure a safe deployment.
Yes. With lower upfront costs and no need for expensive safety caging, collaborative robots have significantly lowered the financial barrier to automation, making them an affordable option for many small and medium sized businesses.
No. Most collaborative robots are designed with easy to use interfaces, including graphical tablets and hand guiding, which allow non programmers to set up and teach the robot new tasks quickly.
They excel at repetitive, predictable, or ergonomically challenging tasks. This includes machine tending, assembly, pick and place, and palletizing, especially in environments with high product variety and frequent changeovers.
