Hi guys,
I tried integrating a SICK safety scanner with a UR5 robot last week. My goal was to have the go into Reduced Mode settings as soon as the robot moved across a certain line. I had no problem setting up the safety area and editing the safety settings for the Reduced Mode. However, the robot's transition into the reduced mode is very sudden and creates a jerking motion when crossing the line. The only way I managed to reduce the jerking motion was to reduce the speed and acceleration differences in the settings.
Is there a way to create a smooth transition between the normal working settings and the reduced mode settings with Universal Robots?

Another thing that can make a big difference is using a blend radius on that waypoint to smooth it out a little more.
My goal here is to change the robot's speed when someone approaches the robot. For example:
- 3m = 100% speed
- 2m = 50% speed
- 1m = 0% speed
Having a safety scanner will give an input to the robot when a person crosses a certain plane, whereas the UR's safety planes will not be triggered when a person gets too close to the robot.@Stefan_Stubgaard
Do you know if there is a way to smoothly transition from normal mode to reduced mode when using a safety scanner?
@Tim_Smith @abeachy_HG24There is no way to smoothen the transition when transitioning between Normal and Reduced mode and vice versa.
During certification of the Safety system, it was a demand from the notified certification body, that the transition must be completed within a given timeframe in order to conform with the safety standards.
