The end of the video shows off our amazing range, but we now have new foam discs not seen in the video so it shoots farther and the balls always land in the same spot!
Features:
-Swerve drive
-180° shooter
-48 ft range (with the new foam not seen in video and photos)
-Dead on accuracy
-Use of camera and ultra sonic ranger
-Fast launcher
-Amazing drivers that can drive as well forwards as backwards…with the trailer on
I like that idea for the shooter with the really big angled wheels…that’s clever, i never thought of that. How much control do you have over the distance that you can shoot balls?
I’m curious… does having a shooter capable of ludicrous speed have any negative effect on the fine-grain control needed for short-range shots (2-4 feet)? Changing your reduction to halve your distance would double your resolution for the mode you’ll be operating in the vast majority of the time, but I can’t really estimate how important that’d be.
What we have found is that, we can get it in the trailer at any distance, the range doesn’t effect the accuracy. There is enough difference in the speed of the motor that the shooter can shoot at anything in between the min and max.
Unless you made new ones, those bumpers aren’t legal. The plywood behind the noodles has to be 6" long, and can’t extend past the frame. It looks like you just made the noodles 6" long.
Out of curiosity, what is your firing rate? That’s a very neat shooter design - but I’m wondering how quickly you can cycle balls through it and maintain your accuracy.
We won’t have trouble with any dumpers. We have a strategy to deal with them along with our drivers that are great at escape moves. I find it hard to believe that dumpers will be an issue for us.
If we want to shoot up close is has no speed up time so balls can fire one after another. With the longer ranges, it takes a small amount of time in between each shot but it is not very noticeable. If we used 2 fisher price motors to power it, it would be really fast firing rate, but we don’t have to weight for it and we already used the other fp for the intake collector. To compensate we have slowed down the spiral to keep accuracy consistent.
we thought we would be invincible with our awesome drive train, but don’t brag on it. we we where in the quarters we got shut down because they decided to have two-three robots to pin us. that swerve drive looks like it’s too reactive. are you guys considering switching to crab in the middle of a match? even with the ability to use swerve and crab we still got pined. also tracking might be the hard thing. you will have to be dead on to make it and driving will be a pain since your turret doesn’t move. at kc bots just seemed to attract to a large group that transversed the field. it’s kind-of like team titanium 1986’s robot which does a lot of the same distances, except with a catapult. they turned out to be dud’s because they where only good for empty cell delivery. not as glamorous as it seems. good luck though.
The drive isn’t too sensitive. In the video was when we were testing it and we were using different code and different drivers. Our drivers are great with the drive. Our turret does move. It is on a 180 degree turret. Thanks for the input.
I’ll believe it when I see it. I have a feeling you’ll be eating your words if you ever come across a dumper like 45, 71, 121 or 1625.
I like the shooter design, very unique. A big plus I see with this design is it prevents broken balls from affecting the accuracy of your shooter.
IMO, and I think the Week 1 regionals have shown this to be true, rate of fire = robot effectiveness, plain and simple. This is why dumpers have tended to be on top. How fast does your system shoot, say, 10 balls? You said speed up times are not an issue short range, but long range you need a “not noticeable” amount of time to get back to the right speed. I’m just wondering what the difference in rate of fire is for you at close range as opposed to long range. Again, if you have numbers I find those much more credible than subjective claims. A video of shooting 7+ balls in a row would be nice (much like 100, 148 and 254 have done).
And any video footage of camera tracking accuracy from 40+ feet? Thats a feat I would tip my hat to if I saw it.
Sorry for the long post, I would just appreciate backed up claims as opposed to hype. On all accounts though, please prove me wrong and blow my mind with how dominant your bot ends up being. Thats really what I would like to see. In any case, congratulations on a very unique design that I’m sure will serve you well in competition, good luck!
do you guys have any setting with your camera? you might want to look into having a laptop as part as your driver station (you can apparently have a video output only this way though (legally)) so you can have the turret driver aim at the target. to help him a gyro to keep it pointed in the same direction the the turret driver moves it to would be useful, so your drivers aren’t fighting each other in the middle of a match. (if you’ve ever played halo 3 and have been in the warthog turret, same concept). robot tracking has looked nice on some, but it can be bad. that’s why i suggest using the laptop.
I think robots who are good at empty cell delivery and are capable of playing D will be great 3rd picks this year. To me, that’s pretty darned glamorous.
