Object for a wind blade transporter?

Is it possible to model the transporter in the photo attached? It rotates even as the front of the truck is headed in a different direction. bladetransport.png

See if this helps. It's a basic PF to rotate an object about the z-axis a certain number of degrees (dblDeltaAngle) every time period (defined in the Delay block). As the AGV was traveling around a curve I had to split the token and adjust the rotation angle and rotation time so it didn't rotate before or after the turn, but in the turn (rotate-split-token.png). This was more art than science.

I found out the key was to use NetworkNode under "Travel Networks" in the Library, not the path in "AGV" section. In this example I just had the AGV (token.resouce) rotate. I imagine you could just as easily rotate a object on the AGV (token.item for example).

@Kari Payton I'm not sure but what about an AGV network and an attached trailer with a very long "Trailer Gap"?

@steven.hamoen can you provide example? Unfortunately I am not very familiar with AGVs. I tried attaching something to the object but the angle is not there... the blade only follows in a straight line. I can't attatch the file because of the model size.

@Kari Payton Here is an example model. (My idea actually worked ;-) ) I have not modelled the blade. What you can do if you load the trailer you can make sure the blade is already in the trailer and then you can change the rotation of the blade based on the angle between the center of the truck and the center of the trailer.

This is pretty cool. To improve draw performance, I recommend putting the angle code in OnPreDraw instead of OnDraw. OnPreDraw is only called once per paint, while OnDraw is usually called many times.

It depends on what you want to get out of the model. If you will use the AGV with a 'gap', the gap is calculated 'over' the network. That means that the front and the rear will have the same speed. And I think in the case of the picture, the speed of the front and the back will relate to each other as a sine function. And as you mention, visually you will not see the correct behavior as well.

Seems that you want (a) special object(s).
