Shooter designs from the 2008 Overdrive season
 

Does anyone have any links to Shooter designs and descriptions from the 2008 Overdrive season?

I recall there being some robots designed to launch the big 40" ball with the same type of bag and these may be some good design ideas to revisit...

thanks

No links...our team's web page (and forum) disappeared over the years. But I did find our 2008 notebook, and there is some neat stuff in it!

Re: Shooter designs from the 2008 Overdrive season
 

1114's World Championship design would be a good place to start.

It may be a decade before we see another robot as dominant as the Simbot SS.

It'll probably be only a couple months before we see a bunch of robots similar to it though :)

Re: Shooter designs from the 2008 Overdrive season
 

One good place to go would be youtube. We've been researching both shooters and pickup from the 2008 season and have already found a number of interesting designs we intend to prototype.

Re: Shooter designs from the 2008 Overdrive season
 

Packaging that robot for this year's rules is doable but challenging. I think there are better approaches this year but I expect at least one "Simbot clone" to be successful in some way. I think you'll see a lot more robots that look like 16 that year.

One idea that has enchanted a lot of people on my team is the 987-style shooter. This robot actually shot balls a few feet just by reversing its roller claw. I feel like there's some kind of black magic to this and it's not as simple as fast, powerful claw rollers... I guess we'll find out in prototyping.

Does anyone have pictures of that robot? I have scoured the Internet for pictures and video, but have not found anything.

Video of Team 16's 2008 robot: http://www.youtube.com/watch?v=vtMPpETrRNM

One of my favorite robots from that year. That swerve drive is just so smooth! And flop bots are always cool.

Re: Shooter designs from the 2008 Overdrive season
 

Here is a video showing 118, 16, 148, and 1477 in a finals match.

148 might not shoot the ball, but they're an excellent demonstration of the principle that there are many solutions to a given problem. Shooting doesn't have to be a priority.

Care to share?

Re: Shooter designs from the 2008 Overdrive season
 

It's not the kind of thing that anyone but the author could make sense of, I think.

Steven shared a picture of the finished catapault....it has all the info you need, I think.

Nice, how was the launcher (linear punch) set up?

I like the robot in 3 days approach but the launcher might require much more launch range capability for autonomous mode...

Thanks

As far as I understand it, 1114's puncher was a spring powered fire, winch driven wind up. (I think it used surgical tubing for the spring power). The winch used a motor with gearbox to wind it up, and then pieces of an andymark dog shifting transmission were used in a configuration to shift the winch to neutral and let the spring power unwind the winch.

Re: Shooter designs from the 2008 Overdrive season
 

This should give you all of the info you need. It goes into detail with pictures of what mechanisms Simbot SS had to win Championships. Take a look!

Re: Shooter designs from the 2008 Overdrive season
 

Does anybody know how long the winch took to cycle? That is:

How long did it take between one shot and the next firing at max rate? I understand that max rate fire wasn't important in 2008, but this year....

Re: Shooter designs from the 2008 Overdrive season
 

We actually looked at doing a 2008 SS clone of some sort.
After some intense discussions, we feel that robots like 16's and what we've seen with 3 day robots are more suited for this year's game.
If we are just shooting over a truss, then absolutely. But passing, making high/low goal shots, catching, etc. makes it a lot tougher.

This year especially, I highly doubt we will see a dominating robot like SS was during 2008. I hope I'm proven wrong..

Re: Shooter designs from the 2008 Overdrive season
 

We started doing some "resizing" of 1114's 2008 bot and found that the the new aspects that you pointed out make their design quite difficult to apply to this game. It will be interesting to see if anyone can cram that design into a package that can accomplish all the game aspects. I hope to see it.

As for the dominance of Simbot SS, that is a robot with a dominance that will be VERY hard to ever duplicate.

Re: Shooter designs from the 2008 Overdrive season
 

I have not digested this year's rules yet.
Does the "robot in 3 days" conform to this year's rules?

It looks like it might be a good start but might be best to add more punch to the ball launcher and add some way to change the pitch for shooting or passing at various distances.

Also, wouldn't meccanum wheels and a fast geared up bot be useful in this year's game?

I anticipate a lot of scrimmage and a manuverable bot that can get in and out of spots might be the ticket.

Any thoughts on this?

thanks fo the ideas guys...

Re: Shooter designs from the 2008 Overdrive season
 

The winch retracted the launcher back to firing position in about 2 seconds. We could have geared it faster, but it wasn't necessary. (We could drive around field pretty quickly that year, but not that quickly. :P)

Re: Shooter designs from the 2008 Overdrive season
 

Wild guess...2/3 of the time you will be playing defense. So build a drive base that is good at pushing other robots around.

Re: Shooter designs from the 2008 Overdrive season
 

Seconded.

Re: Shooter designs from the 2008 Overdrive season
 

Yes please, please do that.

Sincerely, every one of your future alliance partners.

Re: Shooter designs from the 2008 Overdrive season
 

Considering how much your success depends on how well you work with others how well a team works together and works with others is actually more important than the robot itself.

Re: Shooter designs from the 2008 Overdrive season
 

If done right, a mecanum drive might be a great way to go. Defensively it might be good at being in the way of the low goal and playing 'kinetic defense' whereby you ram another robot at a high speed to disrupt whatever activity they are attempting.

I think just getting in the way, especially causing fast robots to slow down to avoid you and/or force robots to push you (ideally sideways) will be the most efficient way to play defense. I would be awfully surprised if a robot could routinely 'open field pin' another robot and force it back across the field, especially during eliminations. Success against the average kit-bot? Probably. Success against many custom drivetrains with high traction wheels? I am doubtful.

Re: Shooter designs from the 2008 Overdrive season
 

team 1248 has been looking at 2008's game and noticed that only small modifications will be needed to team 16's pick up design. Now the idea of catching the ball with such robot is a bit tougher. anyone have any ideas on teams with catching mechanisms that will fit with a design like that?

Re: Shooter designs from the 2008 Overdrive season
 

I think this will help a bit. im pretty sure this robot was a big factor in at least a regional win. http://www.youtube.com/watch?v=kvAT-a1TkMQ
