We would love any feedback. We want all pros and cons of both systems. Thanks
Need to do some rough calculations of how long it takes to refill the air tank for the pneumatic one, and also how long it would take a motor to pull back the spring (if you use that technique) for the spring version.
Auto is only 15 seconds…you’re gonna kick 3 balls upfield in that time, after you find each one…right? 
Thanks for posting the link to the video Fredi
Thats the plan!
When are you guys going to have any vids up?
Awesome video!
I always try and get my team to prototype more before we decide what we want to do, but it doesn’t always happen… I’ll make sure we watch this video at our meeting tonight. Hopefully they’ll finally realize how important prototyping is.
Thank you for posting this.
Thanks for posting this. I’ll be sure my team sees this. Could be the most influential video of 2010 if you keep this up
Do the prototypes follow the 2 inch extension rule as built?
yes
2 inch extension rule?
Perhaps the bumper perimeter rule?
Exactly. I didn’t know if there was a separate rule.
I think Chris means the no extension outside the bumper zone rule, but bumpers are thicker than 2" so I am unsure.
Chris, could you elaborate or post the rule that applies please? I don’t remember reading a “2 inch” rule in the manual.
You can extend outside the frame perimeter below the bumper zone up to the bumper perimeter for up to 2 seconds then you must come back in the frame perimeter for 2 seconds before extending out again.
<G30> ROBOT Volume – During a MATCH, no part of the ROBOT shall extend outside the vertical projection of the FRAME PERIMETER, except as follows:
a. BALL Interaction Volume – Solely for the purposes of interacting with a BALL, MECHANISMS that are below the BUMPER ZONE may extend up to the BUMPER PERIMETER, for a period not exceeding two seconds. After returning inside the FRAMER PERIMETER, such MECHANISMS are not permitted to re-extend beyond the FRAME PERIMETER for at least two seconds.
Sorry guys, I mixed up my inches and seconds.
My one say on design number one is that it looks like you had a hard time with one bump and that it looked like some of the balls didn’t go over. But design two looks like if adjusted correctly, would be able to score from any of the zones.
See this is exactly what I am talking about. The bumpers are 3.25 inches not 2. It references 2 seconds not 2 inches.
We need to be very careful when we post things that a rookie or casual poster might see and think is a real rule.
As a point of reference, can you describe how far you were from the bump and from the goal while testing these?
thanks for sharing!
definitely more effective than I anticipated a simple kicker could be
Awesome Fredi, thanks! I’m tending to like the surgical tubing. Simple, no significant weight budget costs, no need to store air, etc. I also think there’s a simple way to release and reload that, but I’d need to prototype to be sure. We’ll provide and feedback info we find out here. Our team doesn’t formally eet again until Saturday, but we may prototype with a few folks before then.
Rock on…
We are going with 3 inches outside the frame perimeter. Pool noodle is 2.5 inches play wood is .5 inches so three inches. It moves in both examples 6 inches three in three out.
we had the back of our robot dimensions against what would have been a bump. Wide side facing the goal. Farthest from gal you could be in the midfield.
