Does a cobot need a safety fence or other safeguards?

A cobot may need fencing or other safeguards, depending on the complete application. The decision follows the assessed hazards and the validated operating arrangement. The fact that an arm supports collaborative functions does not automatically permit people to stand beside every tool or process.
What this means in practice
A sharp workpiece, a trapping point, or a hazardous process can require additional protection. The appropriate measures may include physical separation, controlled access, or other validated protective functions. The design must account for normal tasks and foreseeable interventions.
Safeguarding follows the application
Consider how people approach the cell, what they need to do there, and what hazards remain during those activities. Separation may be necessary for a process or tool even if the robot supports collaborative operation. Different tasks within one cell may require different access arrangements.
The final design should account for foreseeable misuse and interventions as well as the intended production cycle. Protective functions and access procedures need validation in the complete system. Reassess the arrangement when product geometry, tooling, loads, or operator interaction changes.
Key points
Assess the tool, workpiece, fixtures, and surrounding equipment.
Define where and when people may access the system.
Validate the selected measures for the actual application.
Practical example and next step
Do not choose the safeguarding arrangement from a product photograph or general marketing claim. Have the complete installation reviewed against the manufacturer's instructions and applicable requirements. The answer can change when the same arm is moved to another process or fitted with a different tool.
