A Safety Guide for Operating Collaborative Robots


The knack of collaborative robots to share roles with manual operators and compliantly adjust to new necessities can give significant yields on capital investment in a broad scope of industrial applications.

Producers can utilize a collaborative robot to secure the rewards of coordinated security features that let them work with or in close proximity to manual operators and enhance efficiency on a broad scope of strenuous tasks.

Regardless of the various wellbeing features that incorporate light frames, crash detection tech, among others, suitable security measures should be at all times put into consideration for general usage. They can be used in the end-effector, gripper, and other active components and located in a shared work area.

Safe application dependent on full risk evaluations is significant for guaranteeing the success of shared robotic use. This article discusses what a collaborative workspace is and the safety measures that apply in these spaces.

What Does a Collaborative Workspace Entail?

Cobots execute mechanized roles alongside other tools that could possibly cause destruction. The territory wherein a cobot works, alongside any gear or extra hardware, is regarded as a collaborative work area.

As highlighted by ISO 10218, this is an area inside the fortified territory where the machine and manual operators can execute tasks concurrently throughout assembly processes. Also, TS 15066 characterizes it as the space inside the working area where the machine framework can accomplish tasks alongside a manual operator during production runs.

It is imperative to rundown all extra gear in the comprehensive, collaborative mechanization scheme. Producers ought to assess every gadget for likely risks and wellbeing sensors to utilize in order to avert equipment damage and harm to manual operators. Likewise, the collaborative work area should be well labeled.

Security components are by and large very simple to assimilate into a collaborative robot scheme. There are a couple of solutions that can be implemented in a company in order to safeguard the collaborative work are, and they include:

Open Area Welfare Safeguarding Solutions

Security area checkers are the most renowned defense for collaborative robots. They are likewise the absolute least complicated components to assimilate into applications with low risks and few extra bits of gear.

Limited Area Welfare Safeguarding Solutions

Safety light curtains and security switches are utilized for applications with risks or high-velocity movements for enhanced efficiency.

Active Threats Welfare Safeguarding Solutions

When a risk is in existence or an activity could cause a peril, manual operators flick the “deadman” switch. This is a switch that autonomously reverts to the “off” position if the operator neglects to apply pressure after some time.

Maximum Safety in All Applications

It is fundamental for producers to confirm their cobot applications for security across all activities. Each application is exclusive; however, there are a few rules producers can follow while assessing the safety of a collaborative robot. Thrust and drive risks could still be lurking even if the cobot isn’t in motion.

Hand Operation Safety

In the course of the design and security arrangement, producers should guarantee that hand-guiding functionality can only happen if and when:

  • The robot is stationary.
  • The intentional mode decision has been made.
  • Speed and power checking parameters are in place.

Two-Step Verification

Regardless of whether you are firing up the cobot or recuperating from a crisis halt, there should be a purposeful functionality that boots the machine and guarantees that manual operators are safe and that no risks exist.

For example, when an operator activates an e-stop, the machine should not implement an automatic re-start; rather, it asks for input from another operator in order to verify the command and execute the task.

Security Authentication

It is significant for producers to have a wellbeing evaluation service team audit all the adjacent regions and gear and to have a security remediation administration implemented if need be.

Security service teams will carry out an on-site audit to investigate the gear’s safety, ratify certificates, confirm security border settings and record that the security authentication process has been concluded.

Final Thought

To sum it all up, collaborative robots are widely regarded to be safe. However, they still require a risk assessment, and some measures should be put in place to ensure that manual operators are protected from harm, as illustrated above.
