Guarding Selection for Robot Cells
Guards are the primary control; everything else is secondary.
Options and their role
| Type | Typical use |
|---|---|
| Fixed guard | Areas that need no access in normal operation |
| Interlocked gate | Access for loading and maintenance |
| Light curtain | Frequent access with a defined opening |
| Safety mat or scanner | Floor-level detection zones |
| Physical barrier with mesh | Separating robot from walkways |
Selection considerations
- Distances must be calculated for the stopping time, not estimated.
- Guards must resist foreseeable impact and be difficult to defeat.
- Access points must be chosen with the people who use them.
Guard selection follows the risk assessment and applicable standards. Involve a competent safety specialist.
