This is my most popular video on YouTube with more than 175.000 clicks.

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

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.
