Questions and Answers

What is the primary consideration when positioning a robot within a factory?

A safe position far away from danger points, such as other robots, operators, and structural pillars.

What is the key factor in determining the level of safeguarding required for a hazard?

The possible severity of the accident that may occur.

What is the purpose of erecting a barrier around the perimeter of the robot's work envelope?

To prevent light and radiation from weld flash and to provide a physical barrier to protect operators and others.

Why is it advisable to use slower speeds when programming a robot's operating speed?

Study Notes

Software stops should be created for each axis, allowing each axis to stop before mechanical stops are needed.
A virtual version of the work envelope exists, causing the robot to stop if it moves out of this space.
Access to the cell should be via an interlocked gate or light curtains.
Sensors on the robot detect the edge of the work envelope, including proximity sensors and process sensors like light curtains.
A pressure-sensitive mat between the gate and the robot shuts down the robot in case of unauthorized access.
Emergency stop buttons should be easily accessible, red, mushroom-shaped, and protrude from the surface they're mounted on.
The robot should be positioned in a safe location, away from danger points, with safeguarding around it.
Hazards that may cause personal injury should be safeguarded, with costs balanced against potential accident severity.
The safeguard should be acceptable to government inspection authorities to achieve a working, economic, and safe solution.
A barrier around the work envelope's perimeter is necessary, either opaque or able to filter light and radiation from weld flash.
A correct operating speed should be defined and selected for production conditions, with slower speeds advisable during programming.
The robot's operating speed should prevent it from moving too far too fast when a mistaken command is given.
