crane collision to simulate pick'n place

Hello,

thanks @Afonso Teberga for your model with crane collision management. I resused it. My need is to simulate a machine with 2 pick'n place (2 cranes) to supply 5 identicals processors. I resized the 2 cranes in your model to my need and so, the crane collision doesn't work anymore. Sometime the cranes cross together. Can you help to understand the issue?

Hi @Julien G6

1. You should change the agent system proximity trigger from "On Enter Proximity" to "On In Proximity" (just add this trigger and cut and paste the code into it). More info on the proximity triggers here. This allows to dispatch travel tasks on each update interval if cranes are close.

2. Uncheck the "Resolve Distances and Forces on the X/Y Plane Only". Otherwise, the bounding volume of each agent will allow one crane to pass over/under another, without violating the collision radius.

The attached model has these instructions implemented: crane-collision-answer.fsm

Best regards
