Crane cannot do the TASKTYPE_TRAVEL task

Hi guys,

I'm having to make a controller for an overhead crane, which it will give 4 small subtasks for the crane to operate: travel before pick -> pick load -> travel after pick -> drop load

The problem here is when I try to create a task sequence with only the TASKTYPE_TRAVEL, the crane doesn't move. It only moves when I add the TASKTYPE_LOAD into the task sequence but I don't want to make it like that, I want to have 4 separate task sequences for each subtask.

I tested with the AGV vehicle and it is possible to run it with only TASKTYPE_TRAVEL, is it because of the configuration of the crane or did I miss something here?

The above picture is my plant setting, the crane travels to those queues and pick/drop loads into them.

Thanks!

Use TASKTYPE_TRAVELTOLOC for the non-loading travel components.

Oh thanks, I forgot about the traveltoloc type, it works now. Although turning on the navigator for the crane would also solve the problem, is there any difference with it?

Yes the difference will be that it uses a single speed/acceleration and the navigator's chosen path rather than the L>XY>D sequence (or your own variation of that) and the split speed and accelerations of the crane components.
