Success with Tank Treads

[Gary Dillard]

Looks sweet again Mike - and to the point of this thread, you can see how much design and machining time goes into making a tread system work. The sprocket you see there comes solid stock, just the teeth and the bore cut; all the weight reduction getting to the cool looking spokes and the attachment holes plus the drive shaft takes design, NC programming and machining time.

BAck in 95 when Nashua was a well known team, we used tracks for our bot...they were so well designed and made that they did not need to be replaced until after nationals! adn they were on it since around week 3! now the bot did horrible, but the drive was a tank!


Our team this year(134) has taken advantage of the awesome breckoflex tracks, they are totally amazing, a self tracking feature? who woulda thunken! and hey CD...Pembroke this year will be a force to be reckon with.

Hmmmm...... notice in my post I haven't said anything about this year's drive system. Could it be that team SPAM has abandoned its 5 years of development of a tank tread system in favor of something more....exciting?

Shhhhhhh... Let's make sure it works first. Afterall, antigravitic drive systems are still kind of hard to control. But we'll get something working by regionals.
