2.4 Risk Assessment
Risk assessment is one of the most important tasks that the integrator must
complete. Robot itself is a partially completed machine, and the safety of installed robot
depends on how the robot is integrated (such as tool, obstacle and other machinery).
It is recommended that the integrator should use the guidelines of ISO12100 and
ISO10218-2 to carry out risk assessment.
The risk assessment needs to consider two situations: the risk of robot installation,
robot demonstration and the risk of running robot.
For the non-collaborative installation of robot (e.g. when using dangerous tools), risk
assessment may infer that integrators need to connect additional security devices (such as
activating device) to protect themselves when programming.
2.5 Stop mechanism
All the moving parts of robot will stop when the e-stop is activated. After releasing
the e-stop, no action of the robot is started. E-stop cannot be used as a risk reduction
measure, but it can be used as a secondary protection device. If multiple e-stop buttons
need to be connected, they should be included in the risk assessment of robot
application.
