Timothy Endersby's Lego Mindstorms NXT Double-Tracked Tank

[DLuders]

On Rebrickable, Timothy Endersby posted his Lego Mindstorms NXT Double-Tracked Tank. It is surprisingly capable. His description on his

:

"Double-tracked is my attempt at a robust tank using the rubber treads. I used the rubber treads instead of the hard plastic treads since they have much better grip (and I have no plastic treads). This worked very well. The only down side to this is that there was no suspension. Also, the gears connecting the front and back treads would often catch on the ground. Overall though, I think this could outperform almost any other Lego tank the same size with hard plastic treads."

He created 10-page PDF Building Instructions and a Zip file containing LDraw building files. See 6 pictures on his Mindstorms Podcast website.

cool

the lego rubber tracks are awesome. A small tank using just two of them can push around my large tank (about 10 times the weight) on any hard surface

Yes those rubber tracks are awesome, too bad I don't really have many. :( I wish lego would make larger tracks with larger wheels for them for things like Sariel's tanks or just make rubber track inserts.
