Robot arm moving through FIFO rack when placing part on sink

[Mueller]

Hi everyone,

I’m experiencing an issue with collision avoidance in my simulation and hoping someone can point me in the right direction.

Setup:

• I have a process where a robot delivers parts to a sink
• The sink is placed inside a FIFO rack (standard component from the eCatalog)
• When the robot places the part onto the sink, the arm passes directly through the FIFO rack structure

What I’ve tried:

• Used excludeObstacle command via the robot controller → no effect
• Used PrecisionObstacle command via the robot controller → no effect

The robot still ignores the rack geometry and moves straight through it.

Any help or suggestions would be greatly appreciated!

Thanks in advance.
