rofl, great name for the picture

anyway thanks for putting it up, I've had the design going through my head and wondering how you worked it out since its so unique.

Well anyway how much does the chassis weigh? and what are the different thicknesses of aluminum that you used?

[Alex Cormier]

how much was the difference and strength in from your last years chassis? i never knew you used the foam stuff for bumpers, great idea.

I must know, who did the paint job!!!???

GO 1403!!!

I designed and painted it. The perimeter and all vertical plates are 1/4". The horizontal plates are 3/16". The whole base without anything on it weighed 9lbs. Last years frame got caved in on the ends. This frame took 1 dent before the bumpers went on while Tytus rammed it into our practice bot at full speed, about an 1/8". Otherwise it's incredibly rigid. Personally I would have made it lighter. Another engineer Scott (who welded it) demanded I make it all thicker. Otherwise the vertical plates would've been 3/16 and the horizontal plates would've been 1/8. If we use this design again, I think that's the way I'd go.
Man every time I check delphi there's another picture of our bot on here.

Whoa! Pretty darn cool.

From the looks of it, the treads used on the drive were the same type we used. Problem was that they didn't take friction too well and we had to change for a tougher tread. Were there any problems with them on that particular bot?

Why the #35 chain as opposed to #25?

[Elgin Clock]

I have 4 words for that bot.


Bow Chica Bow Wow!!!

One of the best designed FIRST robot chassis I have seen in my brief two years. Also one of the most original. Great job swamp thing on building a great robot and having a great season. Tytus awesome picture man. Dan awesome work thanks for answering the questions in this thread so far.

Dan, you forget that Tytus is on your team. There is no 2nd tytus, so who is going to drive the beasts that you are going to design upcoming years.

[Koko Ed]

The perfect marriage of form and function. That beauty had some moves. You guys were great partners.

because 25 breaks easier. and #35 is plentifull in our shop because it is usefull for everything. drivetrain, arms, whatever.

Cool pic. I checked out that bot plenty of times at UCF and Palmetto, but never got the chance to get a good view of the bottom like that. Real nice metal work.

These treads were great. We did have one fall off after shipping at our first regional during practice. Maybe the heat caused it, but I'm not sure. 5 of the six were fine. So the one that came off we re-glued it and it stayed through the next 2 days of comp. Then at our second regional we changed them all out, re-glued but also added rivets to all of them. Those are all still on there now and holding great through nationals and some recent demos. Friction wasn't a problem.
Thanks everyone for the compliments
