Lately I’ve realized Flywheels are becoming more common than Double cata. If so are flywheels even better?

Yes and no… the meta around flywheels is that they are really good at teamwork and decent at skills. The only issue with that is the fact that you have to build the flywheel, which is very difficult. The double cata is still in the meta just slowing down a bit because of flywheel.

The meta is actually back roller which is more efficient than dual cata and flywheel.
Here is a video of a back roller that i found

Help me some, it looks like the advantage to the “back roller” is that it can capture and then lift the ball up to the catapult bucket. This means that the catapult does not need to have the bucket touch the floor. But a side effect of this, the launch arm is shorter. Don’t you want the extra arm to get the larger momentum?

What’s the difference between a back roller and a flywheel they both somewhat work the same as you only have to shoot the tip 2 then just keep shooting in the bottom During skills. Whilst in teamwork wouldn’t flywheel work better especially if you are the passer since flywheels would get it to the other partner faster than a roller?
Flywheel has to reload, back roller doesn’t, therefore making it more efficient and allowing you to score more points also i’m pretty sure the world record robot is a back roller

Correct, 60666X, 6699W, and 7163B all of which are in the top 3 MS combined skills are confirmed to have used back rollers.

Does 60666X have a video of their robot?
Oh,Ok we are just starting with flywheel and never knew it had to reload to shoot the ball
Used to. There was a video on the youtube channel Vex101 of 60666X’s autonomous, but was taken down three days after it’s release.

I think that because almost everybody makes a back roller there all the same and not unicuce
Just because everybody uses the same base design doesn’t mean they’re all identical. A wise Joseph Lipper ounce said “steal from the best, invent the rest.”

But Some people copy the same design
Yes, if you half to stack blocks vertically and you see a team do 5 in 10 seconds vs 5 in 3 seconds, at the end of the day its a competition and your gonna wanna take inspiration from there design. Copying a design is ok as long as you put your own unique twist on it.

A flywheel will always be limited by serial shooting. In other words, you can only shoot one ball at a time, even if it’s fast. It is a cool and fun bot for Rapid Relay, but it will never have the highest skills scores, especially compared to a dual (or simultaneous) shot catapult or a hybrid back roller/catapult.
This is because you will always need to dedicate two motors to the flywheel on the top of the robot, pretty much limiting your drivetrain to two motors only (assuming you use two for the intake). A good catapult or back roller can use 4 motors (or a PTO) for the drivetrain, making the bot critically faster for this game in particular.

Uh, you can motorshare the intake with the flywheel. It’s a little unorthodox, however.

It depends on personal preference, but our team uses a fly wheel. It’s better for teamwork, and it doesn’t really affect skills, as the robot can still hold two balls at once.

Correct, team Kinetic force did this with their 3m flywheel/intake.

Also, this is just inaccurate, the flywheel fundamentally can double shoot by shooting before you align, actually making it faster with good driving and 10x better in teamwork.

A bit off topic, but I am trying to build a 3m intake/catapult for a back roller (I have the bacck roller connected to the intake.) We do not have acess to pneumatics, how would we create a PTO so that we have all 3m of power for the intake, and at least 2m of power for the catapult? (mods, if this needs to be in a seperate topic, feel free to move it. if not, can you deleat this text? Thanks!)
