In addition to the 4 powered functions in the original model, Xander wanted to make it drive and steerable, from the PF remotes, thus counting 6 function in total. In order to achieve it, he needed to take out all the gear boxes housed in the middle of the truck, and added some PF motors and IR receivers.
- 1 PF XL-motor for driving the rear wheels
- 5 PF M-motors
- 3 PF IR Receivers
Quite a bit of work...

I have been to write about this since a few weeks ago, and as a matter of coincidence today when revisiting the materials to finally write it, I realized that also today, Xander added a post about one NXTfied version from the same truck, by Ramacco.
The crane truck here was automated using one NXT brick with 2 NXT servos for driving and steering. Furthermore, 3 PF motors were used to control the crane itself.
The NXT controls the PF motors via an HiTechnic IRLink sensor, while the NXT brick itself is controlled from a Nokia 3109c phone via Bluetooth.
