I’m looking at an application whereby I need to create a safe zone around a robot operating area.
I’m struggling to fully calculate to minimum safe distance.
I’ve seen the calculations for light barriers, but for the calculation you need to know the light barrier resolution.
With this being a safety radar, it doesn’t have a resolution. I used the <40mm resolution for getting a rough idea and I’m getting a measurement of 1465mm minimum distance.
However, I’ve seen plenty of machines with way less than that to the light barrier with tools (router heads) that have a slow stopping time, so how can a robot that has a much quicker stopping time need such a large safety distance?
Reason we went with the radar was due to parts being stored within the zone and the radar would ignore them as static objects. Light barriers would be blocked and laser scanners would detect them. Radar recognises them as static objects and will thus ignore them after the delay time.
Ideally I need a tighter safety zone as the customer does not have the space to accommodate such a large area. The machine itself is only 1.2m wide, but with safety it is increased up to 4m.
Firstly, I need to ensure how to calculate the right MSD with the sick rs3 9m safety radar. I’m waiting to hear back from Sick to assist with this
