Last night after work I decided I was going to make the tank chassis work no matter what. I like the idea of having an alternate chassis design that's easily swappable. So, instead of trying to fit puny tracks to an unwilling wheeled chassis I took some scrap plastic leftover from the other one and made a REALLY simple new chassis. All in all I'm pretty happy with it. It could use some smaller stands for the control board but I'm not going to worry about it just yet.


As you can see here, I solved the width problem by staggering the servos behind eachother. Nice and narrow, but wide enough to have good turning force. Yes, I know the tracks don't line up. It's an asymmetrical design and the difference is negligible.


Circuit board is a little high for my taste but I can live with it for now.


This is just a closeup of the lego gear screwed to the servo's output shaft. Nice and simple!


Head-on shot shows some of the brackets I made, also using the red plastic.


Here it is compared to my beautiful Nintendo DS. Good size for a fully autonomous robot I think .
