What Are Cobots (Collaborative Robots)?

Collaborative robots, or cobots, are versatile, scaled-down industrial robots designed to work safely alongside humans. You might think of a cobot as a hardworking, extremely efficient coworker.

Cobots can perform high-precision tasks that robots traditionally could not do, and they are easy to program. Employees can learn how to operate and work with a cobot quickly and without special training. These affordable robots offer countless benefits for manufacturers, from improving worker safety to boosting productivity. Manufacturers in various industries currently use cobots for automating the following tasks:

  • Metal fabrication
  • Packaging
  • CNC machining
  • Loading and unloading
  • Testing and inspection
  • Molding operations

Manufacturers around the world are embracing the use of robots to accelerate production and improve the work environment. According to the International Federation of Robotics (IFR), there are 74 robot units per 10,000 employees on average, globally. Industrial robots, such as cobots, are here to stay. The National Institute of Standards and Technology (NIST) predicts the industrial robot market will experience over 13% annual growth by 2021.

Cobots are a major component of the Fourth Industrial Revolution. To keep up with competitors and enjoy a high return on investment (ROI), it’s worth considering cobots and what they can do for your company. We’ll explain the benefits of cobots, how they differ from traditional industrial robots, the different types of cobots and what the future holds. If you have questions about any of the types of industrial robots we offer at RG Group, reach out to us, and we’ll be happy to assist you.

What’s the Difference Between Industrial Robots and Cobots?

Unlike traditional industrial robots, which are kept separate from workers for safety reasons, cobots are designed to work alongside humans safely. They can be placed in smaller spaces, such as next to humans in an assembly line, and they offer flexible solutions for manufacturers and workers. Cobots are available in a variety of shapes and sizes and come with safety features to meet your production needs while keeping employees out of harm’s way.

Overall, cobots differ from traditional industrial robots in that they are:

  • Lighter weight
  • More streamlined
  • Have a softer touch
  • Safe around coworkers
  • Easier to use
  • More affordable
  • Easier to maintain

What Are the Benefits of Cobots in Manufacturing?

Those who work in the manufacturing industry may be afraid that cobots are going to replace humans and eliminate manufacturing jobs. According to a 2016 study by the Organisation for Economic Cooperation and Development (OECD), only about 9% of jobs are automatable. It’s important for supervisors and employees to understand that cobots are designed to assist humans and make their work more satisfying –– not replace them. Cobots exist to complete boring, repetitive and hazardous tasks so human workers can put their skills and talents to better use. When cobots and humans form a team, everyone benefits. Here are reasons to welcome cobots into your facility:

benefits of cobots in manufacturing

  • Easy to use: Cobots are engineered to be user-friendly. Therefore, manufacturers do not need to spend time or money learning and teaching complicated programming. You can integrate a cobot quickly, and you can expect to see positive results fast.
  • Increase worker satisfaction: Cobots make the perfect coworkers. They are built to do jobs that are dangerous or dull. Meanwhile, human workers can use their time and energy to complete more rewarding tasks.
  • Improve safety: Cobots complete repetitive tasks that could lead to strains or injuries in humans. Cobots also handle hazardous materials and chemicals, so humans don’t have to. Lastly, cobots are safe to share a workspace with because they are equipped with advanced safety features.
  • Reduce error: Cobots complete tasks that are prone to human error, and consistently deliver quality results. By performing with high accuracy and consistency, manufacturers can expect waste reduction when they use cobots. For example, a cobot can inspect auto parts for defects for hours on end without making a mistake, whereas a human would become tired after time and likely to miss a defective part.
  • Boost production: When employees wish they have a helping hand, cobots come to the rescue. Cobots are five times faster than humans and won’t make mistakes. Also, cobots don’t need breaks, vacations or sick time. They can work 24/7, which allows you to produce more at a higher speed and meet your customers’ demands.
  • Boost performance: Humans and cobots make an excellent team. According to research from the Massachusetts Institute of Technology (MIT), humans and robots work faster and more efficiently when they work together rather than alone. Researchers found that workers reduced idle time by 85% when they worked with robots.
  • Affordable: You don’t have to spend money to add more floor space to make room for cobots. Cobots fit seamlessly into your existing layout and take up about as much room as a human. Also, they’ll work for you around the clock and ask for little in return. For example, if you lease a Doosan M1013 for $712 a month, and if the cobot works 744 hours a month, that’s equivalent to paying the cobot $0.95 an hour. Overall, cobots are a smart investment.
  • Save money: With cobots, you’ll save money in dozens of ways. First, you’ll experience greater efficiency, which means fewer operating costs. You’ll also have fewer errors to pay for, and you’ll reduce insurance costs and the cost of workplace injuries. Lastly, you can reduce the number of employees needed to complete unskilled tasks.
  • Competitive edge: With a higher output, consistent quality and lower overhead costs, you’ll zip past competitors with cobots on the team.
  • Mobility: Cobots are lightweight and easy to move, so you can put them to work anywhere in the facility without needing to change the layout.

What Are the Types of Cobots?

types of collaborative robots

The International Organization for Standardization (ISO) defines four techniques for operating collaborative robots:

  • Speed and separation monitoring
