Remote Control Lego using a "tank" (A/B) seeting method. It uses an adder/subtractor differential, and a polarity switch off the steering output.

More information on my web site (and a couple better pictures) http://ffaat.pointclark.net/blog/archives/128-Lego-RC-Tank-Test.html

  • I added a link in the description field to my web site-it provides a bit more information.

    I used skids for this test as it was on a tile floor. I'd suggest four casters, one on each corner for stability. (I also tried adding two wheels per side and gearing it down, but the friction losses started to get to bad with the rubber tires, especially when turning).

  • Hello,

    Nice video... Just wondering, did you drive the vehicle using two wheels and two casters? If you did, did you find that this worked out well for maneuverability and stability, or is there another design you'd recommend?

    Thanks :)
