Re: New York 2019

We've been thinking about carpooling already and I doubt it would be that hard to organize if we already have a team interested in this. I'm currently contacting the team in place about getting more funding so we don't ruffle any feathers that we don't have to if it can be avoided. I'll tell you al...

Re: Team resources

Hello! So I (and my team) have worked very hard this year and have compiled a Google drive filled with a lot of resources such as notes and tests for various different events. Our plan was to have this drive keep filling up with information and share it with the future science olympiad people at ou...

Re: Improving Weak Events

I think as a captain or coach it’s important to stress the “we are only as strong as our weakest link” mantra all season, or at least through the last qualifying tournament. As we lead up to regionals, I always stress the following hypothetical - two students, each with 3 events to prepare for - one...

Re: New York 2019

Does anyone know if they released which maps to bring for Road Scholar? Did they send it out by email or is it on the website? This was in an email from the NYC director to states-bound teams from our region, sent on March 10th: “USGS 2019 Symbol Sheets Road Scholar at the 2019 New York State B Tou...

Re: New York 2019

Signups opened at 8pm for those who don't know yet.

For what it's worth, that info was ...

Re: Vehicle Thickness

Oh c'mon! And I was really hoping I was the only one who thought of this... Any reason why the two axles are connected? That's not a diagram of an actual battery buggy, just a "design idea" picture you see when you check out bevel gears at servocity, so I'm not sure what function they were going fo...

Re: Vehicle Thickness

For those of you with 10-20 cm thick vehicles, isn't that too thin to implement a wingnut brake that can rewind to 12 meters? We have our lead screw running from the back of the vehicle to the front. The motor drives the screw at the rear, and a pair of bevel gears join the lead screw to the front ...

Re: Battery Buggy B

So our Science Olympiad team only meets once a week for like 1 hour, and that's not really optimal for testing the Battery Buggy. Where else could I test the Battery Buggy outside of school? You may be able to find a grocery store (or any business with lots of hard smooth floor space) that would le...

Re: Roller Coaster Scoring Discrepancy

I am having trouble reconciling the 2019 Roller Coaster event scoresheet spreadsheet with my calculations based on the 2019 rules. Here's an example: Device height = 40 Gap 1 = 3 Gap 2 = 2 Gap 3 = 4 Run Time = 15 Target Time = 30 My calculation shows: Height Score = 3 x (60-40) = 60 Time Score = 5 ...

Re: Slowing down the ball

I would strongly advise against increasing friction; if your ball by chance stops rolling, you won't hit the finish line. More track (think switchbacks) or a track portion the marble can cross repeatedly (like a half-pipe or funnel) will add seconds while getting the ball to the finish more consiste...

Re: Gear Ratio

My wheel diameter is 2 in, I have 2wd, the vechicle weighs about half a pound. Is this enough info? Where are you at in the design process? If you have a vehicle with 2wd already, what benefit are you seeking in a new motor? Roughly, if your wheel diameter is about 2in, you’ll get just under 16cm d...

Re: Gear Ratio

Those motors you mentioned are also suitable for direct drive - you can attach one directly to a wheel and not worry about configuring external gears to fit on an axle etc. How heavy your vehicle is will determine how much torque you need- the more torque, the fewer RPMs. For what it’s worth my stud...

Re: Conflict Blocks

My assumption is that, given the numbers, the whole-block self-schedule events will also only be offered for 2 or 3 time blocks, but there is no indication which 2 or 3 time blocks each event might be offered in. My experience has been, any self-schedule events would be given a time range ahead of ...

Re: Battery Buggy B

So I'm kinda confused as to how y'all are supposed to use a caliper for steering i dont understand how it steers The car will travel in some sort of arc if the two axles aren't perfectly parallel. A small change in the relative position of the axle will produce a big change in the path the vehicle ...
