It is a special truck called the underbridge unit as it mainly used to do work below a bridge, while the truck stands on the bridge itself. My model built out of Lego Technic has the following RC Remote Control Features:
- Automated extending and retracting the work platform,
- Pneumatic height-adjustable chassis,
- Maneuvering by RC remote control
I got inspired by following video from Firma Moog:

The sourcecode of my model is published on GitHub:

Voice control
In a second version, I control my Underbridge unit with voice commands, keyboard or buttons in a separate VB.Net program.
The serial transmission to Arduino Mega 2560 running via USB. I use Windows Speech Recognition to recognize voice commands.
