Are cobots safe?

Updated: May 29, 2020

In January 2019, the International Federation of Robotics (IFR) published its definition of collaborative robot in a document entitled "IFR publishes the definition of collaborative industrial robot and estimates its requirements", distinguishing which cobots meet the requirements of the standard. ISO 10218-1 and which are not. ISO 10218-1 is an international standard that regulates the safety design, protective actions and guidelines of industrial robots.

Cobots of certain companies are able to provide this level of product safety worldwide using the technology of torque sensors, distinct work areas and numerous international certifications, which all work together to create a unique, optimized and safe environment. The torque sensors allow cobots to accurately detect external forces and stop much faster than conventional current control methods.

Cobots are equipped with torque sensors on joints making them much safer than the use of the conventional electric current control method.

Without the torque sensors, there is no other choice than to detect force by monitoring changes in the electrical current used by the motor. When the cobots are equipped with high performance torque sensors on joints so any force applied to the joints can be immediately detected, making them extremely sensitive to collision detection.

When you look at a workplace that cobots you can see how easily and simply the operators and cobots are able to collaborate side by side. This makes it possible to create secure virtual workspaces without using security fences. To further guarantee operator safety, cobots can move more slowly around humans than in other areas. Setting this allows a higher level of safety for operators, it also increases efficiency and productivity.

Hence cobots can be installed while creating an even safer working environment in which workers and cobots can continue to find new ways to collaborate effectively.
