Re: What Shooter Design was Most Consistent

Next question would be what you think would be the best approach to analytical testing? Some of our programmers are getting overwhelmed with exactly what to test. Ideally, we would like to pin it down to one independent variable (Whether it be the top rpm and change the bottom rpm to the accuracy, or set both rpms and find the corresponding distance, or something of that sort) and test from there.
Furthermore, how much of an exit chute would be necessary for the accuracy to improve? As our robot weighed in at 120 flat, I do not believe we would be able to add much to the chute without significantly reducing something elsewhere (Which, at the moment, we are unable to do because of the fact the robot is bagged)
When we attempted to create an entrance chute to reduce the feeding variability, it simply resulted in a drastic reduction of range (Down to less than 5 feet)

Finally, would it be worth it to scrap the quadwheel shooter all together and design a compression hood shooter in time for Oklahoma Regional (March 29th-31st)
Sup buddy?

I suggest you re-evaluate what tasks you need the shooter to accomplish. You may find some of the early season assumptions are not true, or not necessary.


If you decide a rebuild is in order, You have time. AND:
Please use smaller wheels . My vote is a single axle shooter made with something that "centers" the balls nicely and a very high shot angle. Mix in a nice feeder that puts the balls in with consistent spin, and I like it.

If you need to bounce an idea off of someone/something, feel free to give me a call (skype design sesh tonight? ). I have far too much to list in text and far to little time to do so.
