"Collaborative robots are complex machines which work
hand in hand with human beings. In a shared work
process, they support and relieve the human
operator.'' (source: IFA)

8. Industrial robots
ISO 10218
Safety
21.09.16 8© sirris | www.sirris.be | info@sirris.be |
3 types of safety standards
•Basic definitions and guidelines
•Valid for all machines
Type A (Fundamental standards):
•Safety aspects (B1)
•Protective devices (B2)
•Valid for a spectrum of machines
Type B (Generic standards):
•Detailed safety requirements
•For particular machines and machine types
Type C (Machine standards):
ISO 14121
ISO 12100
ISO 13857
ISO 13855
ISO 13849
IEC 61508
ISO 62061
ISO 11161
9. ISO 10218: Robots and robotic devices –
safety requirements
21.09.16 9© sirris | www.sirris.be | info@sirris.be |
Two parts:
ISO 10218-1: Industrial robots
ISO 10218-2: Industrial robot systems and integration
Four collaborative modes are defined
1. Stop of robot with automatic restart of task
2. Hand-guiding
3. Velocity and position monitoring
4. Power and force limitation
10. Omission of quantified thresholds
Stronger reliance on risk assessment for defining
thresholds (incl: robot, process, peripherals)
ISO 10218-1 – new revision
21.09.16 10© sirris | www.sirris.be | info@sirris.be |
Mode ISO 10218-1:2006 ISO 10218-1:2011
Hand-guiding Reduced speed
(< 250 mm/s)
Reduced speed (no
quantified threshold)
Speed and
position
monitoring
Distances from ISO 13855
Reduced speed (< 250
mm/s)
Distances and speed from
risk assessment
Power and force
limiting
Force limiting (<150 N) or
limitation of dynamic power
(<80 W)
No quantified thresholds.
Combination of limitation
of
Power,
Force,
Speed or
Energy
11. ISO / TS 15066
21.09.16 11© sirris | www.sirris.be | info@sirris.be |
Since 15 Feb 2016
Offers guidance for the process of risk assessment for HRC
13. Cobot add-ons

14. ROI
21.09.16 14
Costs (-)
Robot HW
Programming
Grippers/tooling and sensors
Periphery (input/output)
Benefits (+)
Hard: €€ save labor cost (how much?);
efficiency increase
Soft: quality improvement, ergonomics for the
operator; more job satisfaction; future oriented
