Error of Drive-in Rack

Hello everyone,

An issue emerged when I endeavoured to simulate a simple scenario in which an AGV transports items from a source to a drive-in rack on a path. To be more specific, the AGV transporting items to that rack would result in an unexpected software crash. The following GIF image visibly demonstrates how the collapse happened.

Proposing a viable alternative to the drive-in rack, I constructed a rack that is shaped as a drive-in frame. As shown in the screenshot below, an AGV managed to transport items from the source to the shelf, with the software uncollapsing.

Despite the rack being used as a drive-in, considerable uncertainty remains about how the initially proposed problem arose and ways to solve it. I would be grateful if you could offer any ideas and suggestions.

Thank you

The drive-in rack has special logic for loads and unloads that cause the TE to offset travel to the front of the slot, drive into the slot, and then drive back out of the slot.

When using AGV paths as in your configuration, these extra travel operations don't make sense. Your solution of using a regular rack with a drive-in visualization is appropriate.

I'll add a case to the dev list to address the crashing issue when the model is not appropriately configured for the drive-in rack's extra travel operations.
