Currently we have a four motor single 4-in omni flywheel with a gear ratio of 1:35 and runs at about 3300 RPM for full court shooting. I feel I have reduced friction pretty well. Currently the flywheel shoots with a speed of 1.5 seconds between shots for full court. Does anyone know some good ways of increasing this rate?
Adding a second wheel will definitely help with accuracy, and probably help fire rate as well. Also, to recover from a shot, do you run at a constant motor power, or use velocity control of some kind to increase the motor power? If not, you might look into one. That will definitely help as well.
First, I would switch the wheel to the traction wheels (Attached).
The omni wheels tend to wear down.
Secondly, I would try putting on 2 wheels. By adding mass, the time in between shots is less.
This should help reduce the recoil time.
Have you considered using velocity control like PID or TBH?
Lube it up. Also, I strongly encourage you to use a velocity control program. This can mean the difference between a 2 second fire rate and a .5 second fire rate.
I’d like to clarify something. Adding mass to a flywheel does not change in any way how much energy it takes to launch a ball. What adding mass to a flywheel does do is increase the kinetic energy storage capacity. This means that a more massive flywheel will take longer to bring up to speed and will slow down less when a ball is shot, making shots more consistent. If you have the proper amount of compression and grip on your flywheel, adding or removing mass shouldn’t affect fire rate.
Putting zip ties on your flywheel will allow you to increase speed (by some of the methods described above), and keep accuracy similar. When the flywheel is traveling that fast, the plastic wheel will bend and warp, and this will prevent this
