Why does not the forklift lift the nails using A navigator?

Hi everyone!

I have a very simple problem, I want to use the Astar navigator with a forklift, the problem is that when I add the forklift to the Astar navigator, I stops using his nails to put the boxes in their position.

If I use nodes, the problem does not exist, but I want to use the Astar navigator Logic.

Thank you for your answers, I think is a very common problem.


Thanks!

It looks like the using the A* Navigator for offset travel doesn't handle the Transporter's lift - it assumes it can just find a new route and not worry about 'baked in' animations of the offset travel.. Unfortunately the Transporter doesn't have an onBeginOffset trigger for us to use Process Flow to override it, and even if it did I expect it wouldn't be triggered since the A* is bypassing it.

@tomasz.mg,

Hi! I tried to use that option, but if I check that option, then sometime the forklift ignore other objects that are in the astar navigator, I attached a new example with that problem.

Hi @Carlos R17,

Unfortunately, the attachment in your last comment did not work correctly and we are unable to access your model. Would you be willing to upload it again? This is a common problem with the Answers forum that we're trying to fix, not something on your end.

Here is the model: Forklift_1.fsm

I tried to use the "Travel offsets for load/unload tasks" but it didn´t work.

Thanks!
