PostSubject: Horizontal Spinner speed?   Wed May 06, 2009 1:45 pm

Hey Everybody,

I'm trying to design a 15lb horizontal spinner (an under cutter, a little like Rugburn, if anybody remembers that robot) and I was wondering; does anybody know a way of figuring out an estimate of the optimum speed for a disk like object with a diameter of about 18 inches?

thanks

this tutorial is awesome. It covers EVERYTHING. start at like page 156 (spinning disk design). It'll talk about that, then tooth design, which helps you figure out how far to make the teeth stick out for a given speed, so if you have your tooth depth set, you can calculate the optimal speed...

No Timothy Higgins 1 had an 18 inch weapon and we actually made it larger, we added on some other pieces and it ended up being more like 23.5 inch diameter by the 2nd match.

But Timothy Higgins is Jake's robot; I didn't complete my design for my robot this year fast enough, so I ended up working with Jake; that's not gonna happen next year.

you were. because it was a dual spinner. I originally wanted to do that, but when i weighed the weapon we had on Jake's bot, I decided that a dual spinner wasn't happening at 18 inches.

Remember, this is someone from the team that built a 8+ inch diameter drum as well as a 6 inch diameter drum, as well as a 120 with armor thick enough to only receive 1/6th inch deep scratches from a full-on spinner hit. Overkill is their business.

my disks actually didnt even weigh that much it was just the diameter every one on the RFL forum went nuts on me about. Do you have any pictures of Timmothy Higgins?

You know what's even more crazy? our robot weighed 13.5 pounds. and our weapon itself weighed something like 4 pounds. Nope Cody, I'm sorry, I don't have any pictures, somebody else might. I'm almost positive Senai does, cuz I'm pretty sure he took a picture of the robot where Axiom took a clean, almost 1/2 inch chunk out of the robot.

Really!? I would not have guessed that at all. I was thinking probably around somewhere between 3k and 5.5k

I don't have a picture, but I have a solidworks drawing of the robot without any motors or wheels or the extra parts we added at the competition.

Ya I mean seriously???? WTF???? your robot is WAAAYYY overkill. And Jake's robots are always absurdly overkill on being anorexic. Do you know what KV our Mamba Max motors are?

2 A123, but I was hoping they were the 4700 KV ones, but all I probably need/want is really like 2100 KV or something.

We are DEFINITELY the overkill team. Will Bales with is overkill destruction, Jake Fein with his overkill missing weight in his robots, Will Meeks with his overkill organization and speed when you ask for a tool, Jake and Gabe with their overkill arguments, Win with his overkill not working weapons, Jake again with his overkill bad driving and overkill anxiety, me with my overkill complicating a robot design, Mr. Dubard with his overkill badassness and sometimes anger too, Alan Schimmel, with his overkill armoring of the 120 and his overkill assholeness; Will, help me out, add some more.
