Prototype Small Wheeled Shooter
We just posted a blog entry about our current prototype shooter. It uses much smaller diameter wheels than many teams that we have seen post of CD. We're hoping this idea might inspire some teams that are struggling to package their large shooters.

Re: Prototype Small Wheeled Shooter
The blog entry has the full specs for the prototype. The two motors are a BB550 and a BAG motor.

Re: Prototype Small Wheeled Shooter
So you're actually spinning the 2nd wheel slower than the 1st. What made you decide to do that? Seems everyone is making the 2nd wheel spin faster than the 1st.

Re: Prototype Small Wheeled Shooter
Allen,
This is great work! I admire your lack of hesitation to give away this information. Shows you and your team's true colors. Thanks and good luck at making it even better! -Parker P.S. - Have you tried shooting from the floor? What kind of angle do you expect to have to pitch the shooter to for the 3pter?

Also, anyone have any ideas as to how you mount the banebots wheels directly to a CIM? Thanks |

Re: Prototype Small Wheeled Shooter
On their blog they explained that they used a Versaplanetary box with all of the gears within removed. The output shaft of the VP boxes are the same hex as the banebots wheels.

Re: Prototype Small Wheeled Shooter
Thanks, didn't see that there.
Also we were wondering how you direct drive the banebots wheels with a CIM. |

Locking a stage in a planetary gear is fairly simple - look up how people did it with globe motors. It involves glueing the sun gear and planetaries together with something, then dremeling off the teeth of the planetaries so they don't touch the ring gear. FYI, you can't really be guaranteed that you can direct drive a banebots with a cim without installing an insert and broaching it with a keyway. The unfinished bores on the banebots wheels are not actually a measured diameter: it varies. They ream it to .375, but in most cases it comes bigger than the 8mm shaft of a cim from their manufacturer, and hence will not work directly on a cim.
