Why can AGV sometimes load items and sometimes not?

Hi !

I have designed the from-to table so that the AGV can walk as I planned.

At first, the AGV will load or unload item according to the instructions in the from-to table, but I don’t know why some AGVs will not follow the from-to table (that is, they will not load item).

What’s worse is that the AGV will stop on its own halfway through execution.

I hope the AGV can complete all the processes on the from-to table, but I don't know where the problem is.

The picture below is the process flow I established

I need someone to help me find the problem.

Thanks in advance.

You don't have anything in place to prevent multiple tokens 'using' the same TaskExecuter from moving though the Process Flow at the same time.

Either have each token acquire the AGV as a resource first or use task sequences to prevent the AGV from mixing tasks of different tokens.
