Hello,

I am a newbie to this robot field.

I am now making an environment where the robot is navigating to the target human.

I want the robot to stop 2 meters in front of the target human, to avoid the collision of robot and target human. I searched this issue and find out that I should set the xygoaltolerance to 2 in simple goal checker but for me it didn't work.

Is there any other way to solve this issue? Thanks in advance!
