1.6 Intended Use
1.6 Intended Use
UR robots are industrial and intended for handling tools and fixtures, or for pro-
cessing or transferring components or products. For details about the environmen-
tal conditions under which the robot should operate, see appendices B and D.
UR robots are equipped with special safety-related features, which are purposely
designed for collaborative operation, where the robot operates without fences and/or
together with a human.
Collaborative operation is only intended for non-hazardous applications, where
the complete application, including tool, work piece, obstacles and other machines,
is without any significant hazards according to the risk assessment of the specific
application.
Any use or application deviating from the intended use is deemed to be impermis-
sible misuse. This includes, but is not limited to:
• Use in potentially explosive environments;
• Use in medical and life critical applications;
• Use before performing a risk assessment;
• Use where the rated performance levels are insufficient;
• Use where the reaction times of the safety functions are insufficient;
• Use as a climbing aid;
• Operation outside the permissible operating parameters.
1.7 Risk Assessment
One of the most important things that an integrator needs to do is to make a risk
assessment. The robot itself is partly completed machinery, as the safety of the
robot installation depends on how the robot is integrated (E.g. tool, obstacles and
other machines).
It is recommended that the integrator uses guidelines in ISO 12100 and ISO 10218-2
to conduct the risk assessment.
The risk assessment shall consider two scenarios:
• Teaching the robot while developing the robot installation;
• Normal operation of the robot installation.
If the robot is installed in a non-collaborative installation (E.g. when using a haz-
ardous tool) the risk assessment might conclude that the integrator needs to connect
additional safety devices (E.g. an enable device) to protect him while program-
ming.
Universal Robots has identified the potential significant hazards listed below as
hazards which must be considered by the integrator. Note that other significant
hazards might be present in a specific robot installation.
