Tracked R/C chassis
About this creation











this video demonstrates the vehicles maneuverability in both forward and reverse


this video demonstrates the function of the remote


this is a demonstration of off road capabilities. I will make more difficult obstacles once the vehicle is complete.


this is a demonstration of the gearbox, going forward, right, left, neutral steer right, neutral steer left, reverse reverse right, reverse left.

Here is my first R/C tracked chassis. I don't know yet what kind of vehicle it will be, something along the lines of a dune buggy perhaps. It uses a differential steering gear box. This means there is a drive motor and a steering motor. This also allows it to be controlled like a regular car, instead of controlling each track with a separate motor. The vehicle can also neutral steer with using just the steering input, meaning it can turn in place without use of the main drive motor. The reason for this type of steering is that it is more precise and easier control. the suspension consists of a trailing arm/ rocker arm assembly that actuates the shocks located on the inside edge of the tracks. Attached to each trailing arm is a set of three rollers. There is also one large support roller for each side. This is also the only vehicle on MOC pages with differential steering

Fantastic piece of minimalistic engineering; reminded me of the equally astute "south-pointing chariot" - though that one is reputedly 2500 years older :) http://www.newscientist.com/gallery/lego-chariot Your contraption looks like a clever reverse-engineering of the Chinese chariot. I quickly build one myself, and found that with my on/off first gen PF system the steering is way too brutal. I'd have to use wormgears for the steering part I believe. Congrats again. Cheers

This is a very unique vehicle with the use of 2 motors, but 1 controlling both tracks instead of 1 motor to each track. Because of this design, I also learned how to make a "boost" for an r/c car (It would work well for a slow rock crawler). But still, cool design.

Quoting Bonald 1101 Brilliant! I think you should make it into a tank, that'd look cool. :-)
I built it into a space vehicle. something I have never made before

Very nice, I really like it's smooth operation. It looks similar to Sariel's subtractor designs which can be found on sariel.pl This site is is definataly wirth checking out for everyone who's into Technic Lego.

very good job, as usual;)!!! Have you got any plans for a subtractor, because after many try by my own, I must admit that I'm not good enough for this kind of stuff yet :( I found a plan on brickshelf, but using two old motors, and it doesn't fit with the XL motor...thanks for answering, please take a look at my firsts creations I just put online.
