The height required to do so would interfere with their mechanisms for ball loading.
It’s a cool variant that can be used to save height, and space on one side of the robot.
The biggest issue was that we couldn’t get the ratios we wanted with the triangular configuration.
Our cluster gear isn’t big enough to get 3 CIMs and a shifting piston around it.
Ah. Sorry for the misinformation then.
What you said was true, also. The ball did hit the cRio and was close to the CIMs when it was fully inside the robot. There is no way it would have fit the other way, ignoring the cluster gear size.
FIRST (:p) of all, thanks for releasing these! The tech binder is just beautifully made! I had some questions though.
-
It’s mentioned your drive train was designed for sudden bursts of acceleration, but you’re geared for 20 fps+. Why was such a high speed chosen over a lower speed that would have accelerated faster?
-
You had quite a bit of motors and pistons on the robot, how was your battery life?
3.I recall you experimented with alternate material for bumpers this year, how did they hold up?
- No recipes in the build blog? Has the lack of free corndogs doomed us all?
-
In order to have both high acceleration and top speed, we chose to have 6 CIMs. We didn’t want to sacrifice a high top speed, especially on a field as open as Aerial Assist. Also, one of our initial strategies in Quals was to go for 1-assists with solo-catching, and thus a high top speed would be very advantageous.
-
The 6 CIMs on the drivetrain were the biggest power draw. The only problems we had were when we tried to push other robots while in low gear, sometimes the breaker would trip. We would obviously replace batteries between every match, and we also purchased some fresh batteries before Champs because the 12 we’d been using for regionals were starting to die.
-
We didn’t too much experimentation ourselves with bumper material, but we looked at what 971 and other teams did and tried to improve upon it. We used Cordura bumpers for the first 2 regionals and then switched to Sailcloth bumpers after that. The new bumpers had a coefficient of friction as low as .2 (compared to Cordura’s .4 I think). They helped with driving around defense immensely and the material held up pretty well. The biggest problem with the new bumpers was that we ironed on the numbers instead of sewing, and thus sometimes the numbers would bubble up or rub off.
-
I don’t recall how many times baked things for the lab, he could answer the questions better than myself. However, one night we did make s’mores using a heat gun. It was awesome!
I essentially baked the same things as 2013, in the same order, and I was too lazy to copy the same recipe blog posts over from last year’s blog. 
Sorry for asking this a while after this was released. I’ve noticed you guys have mentioned you needed to be creative to get tubing on your intakes. How was this actually done on the finished robot?
I’m not 100% positive, but I’m pretty sure it involved using a bit of lube, compressed air (to inflate the tubing like a balloon), and A LOT of strength to stretch the surgical tubing over the 1" aluminum tube.
We didn’t end up needing any lube, just two people and compressed air, it worked pretty well. To expand, these rollers were one of my favorite parts of the robot this year; simple, effective and cheap.
So is there any chance you guys will release the cad files for this years robot? It would be amazing to be able to check it out on CAD. :]
Colin and Andrew already answered, but another good trick for getting tubing onto a shaft is to coat the inside with plain old rubbing alcohol. It makes it slide better and will evaporate when you’re done and everything is on there.
