Disks landing after contact with the wall

[iggle3]

My team is considering the conundrum of whether it will be worth it to flip the disks after picking them up off the field. I decided that the most important thing to consider is how many of the disks that have been thrown will be upside down. So this is my question. Will a disk making contact with the wall at high speeds be more likely to land label up or down?

Sounds like something to test with a shooter prototype! Maybe your team should try experimenting, and then you could report your findings to the CD community. I'm sure many people would appreciate your work/findings.

It has been my experience (and I have pretty extensive experience with Frisbees, misspent youth and all that) that most Frisbees land right side up when the are thrown, even when thrown at high angles. The major exception is when you throw and it rolls, or when you throw an overhand tomahawk, then they they tend to come to rest upside down.

I also spent some time throwing at a wall and all of the throws landed up right. Those Frisbees have quite a bit of bounce in them.

Now mixing robots and Frisbees might change things, but I think the whole upside down Frisbee deal is a bit overblown. If its upside down just don't pick it up!

i don't think it's worth your teams time to try to flip the disks, if you're going to pick them up off the ground, concentrate on the ones upside up

I can tell what's going to make me shake my head the most this year is watching teams foolishly wrangle with a single disc for 30 seconds or more when it's propped against the wall. Remember efficiency is the key.

I don't have scientific data, but We we play frisbee football, the frisbees almost never land upside down, even after bouncing off walls...

This. If it's upside down, and unless finding another right side up disc is going to take more time than picking up and handling the upside down frisbee, it's not worth it.

I did actually spend some time throwing a Frisbee at the wall. 11-0 it fell right side up, which was also the way I was throwing it. However, that was hand thrown, which means spinning. If you use some kind of ejector that does not impart spin, it will be more likely to fall the other way. But I would guess that between 75% and 90% of the loose Frisbees on the floor will be right side up, unless some team decided to shoot them up-side-down.

we ran a very simple test where we just threw the disks against a concrete wall. 90% of the disks landed right side up. The only ones that didn't land right side up were thrown at highly inclined angles that are unlikely to be done during the competition.

Over the past weekend, we estimated we shot the disks around 200 times. The only times that the discs landed upside down was after a crazy roll and hitting a wall. We had it happen maybe 5 times so I honestly think that it won't be an issue at all.
