PROBms to measure forces<br />
and speeds. Equipped <strong>with</strong><br />
springs and appropriate<br />
sensors, the device can record<br />
precisely the forces generated<br />
in a collision <strong>with</strong> a robot,<br />
and then evaluate them in<br />
software and compare them<br />
<strong>with</strong> the specifications from<br />
ISO/TS 15066.<br />
The challenge in the basic<br />
‘risk assessment’ for robot<br />
applications is that the<br />
boundaries between separate<br />
working areas for man and<br />
mac<strong>hi</strong>ne have ceased to<br />
exist. As well as the hazards<br />
p<strong>res</strong>ented by a robot, the<br />
human’s movements need to<br />
be taken into consideration.<br />
But they are not always<br />
calculable in terms of speed,<br />
reflexes or the sudden arrival<br />
of another person.<br />
Then follow the “safety<br />
concept” and “safety design”<br />
steps, w<strong>hi</strong>ch cover the ‘human<br />
element’ as well as selection<br />
of the correct components.<br />
These are usually a<br />
combination of intelligent<br />
sensors that are interlinked,<br />
and control systems that<br />
make the necessary dynamic<br />
working processes possible<br />
in the first place. The selected<br />
safety measu<strong>res</strong> are then<br />
documented and implemented<br />
in the “system integration”<br />
step. T<strong>hi</strong>s is followed by<br />
“validation”, when the<br />
previous steps are scrutinised<br />
once again.<br />
When supplying in to<br />
Europe, manufacturers of<br />
robot applications are then<br />
subject to the principle that,<br />
by law, they must complete<br />
the assessment procedure<br />
<strong>with</strong> CE marking of the<br />
robot application.<br />
The demands on safety<br />
technology always depend<br />
on the <strong>res</strong>pective application.<br />
