Support_ASRSvehicleTravelsBack_TD

[Tom David]

Community,

At my last training class I got the questions, why on an ASRSvechicle the pick list option “Travel to an Object Destination” in the Unload Trigger is not working.
It works e.g. for an Operator and for a Transporter.
To send the ASRSvehicle back the pick list option “Travel to a Specific Location” can be used.

Maybe I am wrong, but I guess this is because an ASRSvehicle like a Crane is only using travel offset. So the travel task is useless. But the travel to loc task will be executed.
If I am wrong, please correct me, but this is my explanation.

I posted a model “Support_ASRSvehicleTravelsBack_TD” in the Downloads/SupportModels section, if someone is interested in my test model.

Hi,

If you use network nodes then Travel to Object is working, which is strange.

If you use network nodes, then the object hooks up to the Network Navigator. By default, the ASRSvehicle (like the crane) isn't hooked up to the Default Navigator or Network Navigator so they don't do travel tasks, just offsettravel tasks. Once you hook them up to a network, then they travel on the network to do travel tasks.

From the manual on TASKTYPE_TRAVEL:
Here the TaskExecuter travels to the object specified. This is done by make a travel request to the navigator that it is connected to. If it is connected to a network, then it will make a request from the network navigator.
Note on TaskExecuters and navigators: Some objects by default are not connected to a navigator at all. If the TaskExecuter is not connected to a navigator, then it will do nothing for the travel task. The following objects do not connect to any navigators by default: ASRSvehicle, Elevator, Robot.

I guess we also need to add the crane to that list in the user manual.

It seems that TEFlowItems also don't connect to a navigator if you don't use networknode.

By the way, can anyone gives more details on what is a navigator. The manual doesn't say much about it.
