7. Industrial vs collaborative robots
21.09.16 7© sirris | www.sirris.be | info@sirris.be |
Robot Cobot
Payload +++ +
Reach +++ +
Position Accuracy +++ ++
Speed +++ +
Human-robot interaction (safety) + +++
Simplicity of programming ++ +++
‘Plug & produce’ in production + +++
Task Variation (flexibility) ++ +++
Availability +++ ++
+: limited ++: good +++: very good

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

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
