Team 1448 Robot "50 points in 50 seconds"
 

This is a video of Team 1448's (Parsons Kansas) 30pt climber with a frisbee dumper. The climb is completely autonomous and very stable. This is 6 weeks worth of dedication and hard-work. Enjoy and see you at the competitions!

Very impressive robot folks. I can see that playing in eliminations in just about any regional event. What type of drive train do you have?

Re: Team 1448 Robot "50 points in 50 seconds"
 

That is awesome. Is lining up on the corner difficult? We approached ours center front on the inside and we had to add a camera to line up correctly. I am wondering how you get lined up on corner climber, if you have a V shape that autocenters or something.

Re: Team 1448 Robot "50 points in 50 seconds"
 

What makes this video so impressive isn't just the climbing. it's the fact that it's completely autonomous! what kind of sensors do you use to be able to do this autonomously, and how much testing did you do?

Re: Team 1448 Robot "50 points in 50 seconds"
 

That's gonna be tough to beat.

Re: Team 1448 Robot "50 points in 50 seconds"
 

Yah it is pretty difficult lining up the robot, but we have a c shaped alignment guide on the middle of the front of the robot(that is where our camera is) that guides the robot into position. Our driver's are pretty skilled at lining it up now.

Re: Team 1448 Robot "50 points in 50 seconds"
 

Impressive!

I love the big clunk over the corner connectors.

Re: Team 1448 Robot "50 points in 50 seconds"
 

Our drivers manually line the robot into position, and then our climb sequence is initiated through our coding. Without our magical coder Geoff, the climb would be very difficult.

Re: Team 1448 Robot "50 points in 50 seconds"
 

Thanks. Two motor driven front wheels, and two rear-wheel casters.

Re: Team 1448 Robot "50 points in 50 seconds"
 

This is just awesome. I feel like you could speed things up though since it is happening fully autonomously. Can't you cut out some of the pauses? The nice thing about auton is that it will always be the same and you don't have to worry about needing to wait to be sure you are stable cause your stability will always be the same. In addition you can drop off the frisbees in the top goal earlier, why not have them go into the goal right when you are high enough to deposit them. If you don't get it off by a few seconds in a match you will be kicking yourselves.

Re: Team 1448 Robot "50 points in 50 seconds"
 

I hope you're ready to deal with some intense defense on your way to and from picking up the colored disks.

Great work on the robot!

Re: Team 1448 Robot "50 points in 50 seconds"
 

Everyone keeps bringing up intense defense on the climb and dumpers and I don't know why. With a climber and dumper you have to make exactly one trip across the field, where most shooters will be making several trips.

Why would the shooters also not have to deal with this intense defense? Is it because of the big points a good climber and dumper can make? I see full court shooters being able to put up similar big points but little discussion of defense in those threads.

If the defense is going to be that intense on us climby/dumpy bots, then we can put up 30 uncontested points and not even move at all. I know that is our plan if we draw an all defense bot opposing alliance during regionals. How many shooters can put up 30 points without interference?

I just find this topic fascinating and it might be worthy of a topic of its own, but I see it in every climby/dumpy bot thread.

Re: Team 1448 Robot "50 points in 50 seconds"
 

This robot, if impeded properly, will score only 20 points instead of 50 points.

That's a pretty significant point swing for only playing defense on a robot for one minute.


Edit:
There seems to be endless discussion of defense on full court shooters

Re: Team 1448 Robot "50 points in 50 seconds"
 

I agree about the full court shooters if you are talking about someone parking in front of them to block. I guess I always saw that as a possibility in my mind when we came up with our strategy since the game seems designed that way. When I can be 84" tall on that side of the field and you only 60", I always saw that as a danger for the full court shot.

Defense can swing points in large ways for every robot out there. For shooters I think it can be just as big a swing as a climber. A climber with a 30 second climb has 1 minute 30 seconds to make one trip if they go for the 50 and for a large chunk of the game they are protected upon fear of 80 points if they are touching the pyramid. 30 points uncontested if you simply decide to climb right from autonomous position. A shooter is getting bashed into everytime it turns around unless it is in contact with a pyramid and even then some people might feel it is worth a foul to mess up your score.

I really do like this game because of all the strategy discussions, even before seeing all the cool mountain climbers like the one in this thread, or the frisbee rifles in other threads.

Re: Team 1448 Robot "50 points in 50 seconds"
 

We will be able to get to the 30-45 second climb by changing the sprocket size, but we are content with our frisbee dump. Thanks for the comment!

Re: Team 1448 Robot "50 points in 50 seconds"
 

You're exactly right. And even if the defense is so good that they score no discs, they're still good for 3rd level climb, which really can't be stopped.

Re: Team 1448 Robot "50 points in 50 seconds"
 

You may want to consider having your arm be able to pull away from the dumped discs somehow at the end of the routine so it is unquestionable that they are scored. Wouldn't want them to settle in a position where they are touching the robot and not scoring you points!

Re: Team 1448 Robot "50 points in 50 seconds"
 

I don't get the 20pts only. If all else fails collecting the discs we can still do a 30pt climb.

Re: Team 1448 Robot "50 points in 50 seconds"
 

Awesome and so well done. That is almost exactly the design that we failed to pull off...

Re: Team 1448 Robot "50 points in 50 seconds"
 

I'm pretty sure, at least from what it looks like from your video, that your robot did extend past the 54" diameter. I hope this isn't the case since bag & tag was yesterday. :(

Re: Team 1448 Robot "50 points in 50 seconds"
 

Thanks for this! I'm very interested in this rule, and I will bring it up to the team.

Re: Team 1448 Robot "50 points in 50 seconds"
 

20 points is assuming you don't have time to get up to the 30 point level and make the dump.

Any time you can cut off that 50 seconds will only increase your value and your ability to score those 50 points with defense.

Re: Team 1448 Robot "50 points in 50 seconds"
 

Nope, we're very close at some points, but we're good. Thanks though!

Re: Team 1448 Robot "50 points in 50 seconds"
 

"Shutting down" robots is always so much more difficult then people realize. With the pinning rules and contact penalties it's really hard to do it effectively. Combine that with the fact that most alliances put their weakest partner on defense usually leads to ineffective defense. Its nice to think you won't lose to this robot but most teams will.

Great job and good luck at your events

Re: Team 1448 Robot "50 points in 50 seconds"
 

Nice job.

Inauspicious music choice though...I was hoping it wouldn't end by falling off the bar ;)

Re: Team 1448 Robot "50 points in 50 seconds"
 

Agreed utterly.

We've always been great at defense, but preventing a four-disk acquisition + back to the pyramid in 1:10 would be next to impossible.

Re: Team 1448 Robot "50 points in 50 seconds"
 

I bring up defense because it seems to be the variable in this robots routine that is the hardest to control and is most likely to chew up significant time (having a good drive train/drivers always helps).

Good defense is never easy, but there are plenty of robots capable of it. I can imagine this robot being the primary scorer for many of its qualification match alliances. You will see good defense played on you this year. You would if I was on the opposing alliance.

Re: Team 1448 Robot "50 points in 50 seconds"
 

Great job! What mechanism moves the hooks up and down? it looks very similar to our (sub-functional) mechanism.

Re: Team 1448 Robot "50 points in 50 seconds"
 

A motorized rack and pinion system raises and lowers the arms.

Re: Team 1448 Robot "50 points in 50 seconds"
 

"How many shooters can put up 30 points without interference?"

18 points autonomous plus four 3-point shots. 30 points. Piece of cake, defense or no.

Re: Team 1448 Robot "50 points in 50 seconds"
 

I thought the robot couldn't be touching three levels at once?

Re: Team 1448 Robot "50 points in 50 seconds"
 

When is the robot touching three levels?

Re: Team 1448 Robot "50 points in 50 seconds"
 

When its hanging on the first 30" bar, the bottom is touching the first level, then the Claw that moves up and down went to the third level and had touched two levels higher.

Re: Team 1448 Robot "50 points in 50 seconds"
 

The angled bar in between levels 1 and 2 is level 2 not level 1.

Re: Team 1448 Robot "50 points in 50 seconds"
 

Sorry, I thought that your claw was grabbing onto the vertical bar in the third level... Silly me.

Re: Team 1448 Robot "50 points in 50 seconds"
 

No problem. Thanks for looking out anyway!

Re: Team 1448 Robot "50 points in 50 seconds"
 

YouTube and UMG have blocked your video. I would have loved to see it climb.

Re: Team 1448 Robot "50 points in 50 seconds"
 

I believe many teams will demonstrate and every regional that isn't quite a piece of cake.

Re: Team 1448 Robot "50 points in 50 seconds"
 

:(
Glad I got to see it before the hammer fell on the Daft Punk soundtrack. Now wondering what music, if any, to put on our video. :yikes:

Re: Team 1448 Robot "50 points in 50 seconds"
 

Got blocked too. :( How about no music? No music sounds good. If you have to add "music" to make it impressive, then your video isn't impressive to begin with.

Robots sound good all by themselves.

Re: Team 1448 Robot "50 points in 50 seconds"
 

I agree. I'm fixing it now.

Re: Team 1448 Robot "50 points in 50 seconds"
 

Fixing it as we speak, should be done soon.

Re: Team 1448 Robot "50 points in 50 seconds"
 

I agree with you. I will use the upcoming Bayou as my tent pole since that is the Regional I am attending and not the northeast where every robot must be incredible if they had to go to district level events.

At the Bayou I am predicting there will be approximately 40 shooters there, and predicting only 4 could put up 30 shooting points every game. 10% does not represent a piece of cake to me.

I am also predicting there will be 10 climbers of various quality and only estimate 30% of them will be consisitant, so climbing isn't a piece of cake either. :-)

I believe if you can consistently score 50+ points for your alliance, regardless of how you get it, you will be playing Saturday afternoon. And as we all know, then its up to fate, luck, and just a smidge of skill on who wins the event.

The video should be back up without audio.
