AGV Network - Different rotation times and diferent accel/decel in one travel

Hi!

I am building a model with AGVs in which the AGVs have different rotation times depending on whether or not they change their orientation during the turn.

Also, the AGV has different accelerations and decelerations depending on whether or not they are travelling transversal to the path.

The orientation that de AGVs needs in a path is fixed to the path.

I have tried creating different types of AGVs and switching the AGV type during the travel, but it ignores the changes.

Is there any solution to model this?

Thanks in advance,

Iago

We worked on a project that posed a similar problem. In order to be able to change the maximum speed of the AGV during a travel task, we use different load types. These are set on a label on the AGV which is read and assigned as the load type in the "Initialize Travel" trigger.

To change the load type while the AGV is travelling it thusly needs to re-initialize the travel. We found two ways to achieve this.

Either overwrite the travel task with a preempting task sequence that aborts the active one but has the same destination.

Or stop and immediately resume the task executer (we use the On Message trigger for this).

current.stop(STATE_IDLE);
current.resume();

Maybe you can use this method to achieve your goal.

Note: One issue we found is that this caused problems in very rare circumstances when the re-initialization happened just as the task executer was switching from a one-way to a two-way path.

Thanks! This solution solves the problem of the agv ignoring changes during travel.
