Flywheel design


#1

My team was wanting to make a flywheel design, but I cant figure out where to position it on the robot. I have watched Youtube videos on flywheels, and they didnt really help. Could someone PM me a possible solution?


#2

Most teams have it centered left to right and closer to the back part of the robot. If you post pictures of the robot it will be easier for us to see how to help you.

Good luck!

@21jdsutton You really don’t want to put your email on a publicly visible place on the web. @DRow


#4

Agreed. I’ve edited the OP to ask for any solutions be sent via PM, instead of e-mail.

Well, i know this isnt much, but this is what we have for the robot. There is a c-channel behind the tower for support of the robot.

I would make sure to keep the flywheel between your wheel base and lower to the ground, this will help balance your robot and prevent tipping

@3141SLochNutMonster

I have seen different versions of a fly wheel, witch kind would be the best for my robot?


#8

This is what ive got, but im swapping to a different design. I didnt directly mimic any one robot for the ideas here, so may not be optimised, but i do know that the gear train here is no good.

@Lil Shroomy

Thats the kind of wheel i was thinking of doing. But i would have to put it in the back with support. idk


#10

I was wanting to use a flywheel, so where would one possibly go on my robot?


#11

Inside of your lift? Pictures would be helpful, as well as tentative design ideas.


#12

start with #10, and go up to #12. It should cover most of what you’re looking for.

Well, we only have 4 more meetings/practices this month before Christmas break, and then 2 after the break is over. Would my team even have the time to fix the flywheel and program? My team is kinda slow and doesn’t like listening to me(the captain).

BTW, we are not using the 5 system, I would use it, but the V5 system is on back order in my region, idk when we would even get it in.

Here is a picture of the robot I currently have. I was debating over my weekend whether my team should do the flywheel or do the pusher. Its kinda been a stressful weekend.

Ships in 8 weeks

(Btw, it probably wont come anytime soon)

There’s a lot that can go wrong with any flywheel. How long are your meetings? They’re definitely superior to punchers, but are also a lot more complicated. Punchers are quick and easy. You could probably get one done and mounted ina n hour or two, and then spend the rest of the time practicing.


#16

You should take a look at the DiscoBots design from Nothing But Net, it is a well built robot that has become the benchmark for vex flywheel robots.


#17

Make sure that your center of gravity is just right. With my robot, I mounted my flywheel relatively towards the front, and the robot ended up being really front heavy, and turns on the chassis were hard to control. I ended up mounting the battery at the very back to increase back weight and it seems to work very well. It shouldn’t matter where the flywheel is placed, but just make sure you have a good center of gravity, otherwise it will be a challenge to park, for turning, or tipping could occur. We just competed Saturday with our flywheel robot and it went really well! For timing, it is more beneficial to do a slip gear design (catapult or puncher) because it is less fine tuning with programming and quicker to create into its final form, but if you have the time, by all means go for the flywheel design.


#18

Our practices last from 4:00-6:00 on Tuesday’s and Thursdays


#19

Yeah, you’ll probably want to do a puncher. MAke sure you get some good practice in.


#20

I can’t help with a flywheel but I would recommend doing a catapult. They’re consistent, easy to design, and accurate. At the stage you’re at in design a two-ball catapult could be easily implemented.

E: Noticed you were on cortex, a flywheel would be good as well, because you have 12 motors.
