- Going to the Qualifier, here is a quick video of our 445 point run.
UPDATE 3: We won the So-Cal Championships and are now going to the Worlds. We need to raise a lot of money so, can you help us? Every dollar counts! www.gofundme.c...
UPDATE: At the qualifier we scored 300 points. Lots of work to do before the So-Cal Championship!! :)
UPDATE2: Thanks to team SWARM for pointing out that we can't score the rain on top of the other two waters. So we are at 435 until we fix that!

Nice! 445 early November is very good!
This weekend? Good luck!
Nice!Hey, Im frum the JERICHO DYNAMICS team,and i think it's really CCCOOOLLLLL.Wait hal9000 roboticz I know you and i watched your videoz!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!1 nice
Are there instructions you can share with us? I absolutely loved the door that was responsible for the water collection
Nicely done
Thanks!
that's awesome! Our robot only scores 355!
Sebastian Bratt my team did terrible we got 35 points but got to the championship somehow
Sunny where did u go?
I may be wrong, but I think the rain has to be making contact with he mat
Oh! We missed that. I guess we are at 435 until we fix it. Thanks!!
The rules: "M04 - RAIN Make at least one Rain come out of the Rain Cloud. " I don't see anything about touching the mat.
no he is talking about the water stacking
kelly7873 - when they put the rain the box target it has to be touching the mat am I right?
Mindstorms Man - SWARM the rules say touching the mat but they also say "Water
may be touching the target, and/or other water," I would say stacking a rain water on a big water is ok. Up to the Ref?
you guys seem well prepared for state and worlds. now, like my team, we shall wait for state...
In our area, there is a qualifier tournament, a regional championship (Southern California) and then the World Festival. Several teams advance from the qualifier to the regional, but only the single Champions Award winner advances to the World Festival from there. How does it work in your area?
Same works here, I am in Utah. We have a qualifier, then state, then either nationals or world. We have a second award that goes to nationals. I have been on 2 different teams and both went to nationals. This year, however, the team that always got first isn't participating so we have a good chance. We are planning on posting our robot runs on youtube so once we get everything done, I could send you a link :D
UPDATE : We didn't make it to world festival but we made it to Legoland. Also a quick tip for the water collection, try and use the rubber pieces to keep the grip on the two big waters.
Are those 2 car in the start the pull back motors? R06 - NON-ELECTRIC ELEMENTS
- Use as many non-electric LEGO-made elements as you like,
from any set.
Except:
Factory-made wind-up/pull-back “motors” are not allowed
Yes that's what we thought but one of them looks like an arm is pushing it
We powered the cars with lego rubber bands that are wound around an axle. When the robot leaves base, it releases them by getting out of the way.
Awesome thinking. I've tried to get the team I coach to think like that
We just posted a new video that explains the details on the autonomous vehicles. Thx!
Hi, I'm really amazed that you can get this done in such a short period of time. I was wondering as you brace the slingshot like shown in the video, does the slingshot have to be in direct contact with the mat like the water well? Thanks
We think the rules say that the slingshot does not need to be in direct contact with the mat. It can be in a container above the mat as long as it is over the target area. Thanks!
okay, thanks! big fan from Singapore!
Awesome! How often do you meet per week?
Twice a week for 2-3 hours per meeting with some all day meetings on the weekends. Thanks!
Thanks for your quick response! How reliable is your robot? So if you let it run 10 times, how often does it get the 445 points?
Right now, perfect runs are about 1 in 10. 300 was our high score at our qualifier tournament. But we track consistency numbers for every mission and are focused on making things more consistent now. Our advice to teams is to definitely do as much consistency testing as you can, and when you see something go wrong, stop, figure out what went wrong, and ask "is there anything we can do to make sure that can never happen again?"
Yeah that's definitely a good idea. From which country are you? Maybe we'll meet sometime.
We are in southern California. We hope we meet your team sometime too. Thx :)
Did you keep the same base robot?
We kept the same base but we added a second medium motor and two more light sensors.
Are you guys going on Saturday or Sunday at Legoland. You guys were GREAT!!!!
Thank you! We will be there on Sunday.
Nice us too
Which Sunday will you be competing on?
On Sunday Dec 3rd.
Our team looks forward to seeing you at the competition then! Your robot is amazing!
How many motors do u guys even have on every attachment? That’s insane
We don't put motors on our attachments but we have 4 on the robot, two medium and two large. We use the two mediums to control our attachments. For more, go to our video on our TH-cam channel that introduces our attachment system. Thanks!
You can't use your hands to pick up the robot. That's a penalty. :( Try programming the robot to go back to base by itself.
The rules only make it a 5 point penalty, but I think it should be a much worse penalty when the team intentionally abuses the penalty rule. Elsewhere in the rules, it says you can't deliberately try to break a model to achieve the mission. There should be a similar rule for picking it up because the robot accidentally crashed and is stuck vs. picking it up on purpose because it's your strategy.
The touch penalty is part of our current game strategy and computed in the points. If we can get down to 3 runs instead of 4, maybe we won't need it. The penalty does seem a little low this year. We saw a team at a qualifier take 5 touch penalties on purpose and score pretty well!
FLL Team Water Works Yes, and I didn't mean to suggest you were doing anything wrong. As long as the rules are the way they are, it's entirely legitimate to use it as a strategy!
Ctrl-Z (champions of St. Louis world festival) took a touch penalty last year, so they could do more missions in the time given, by saving time going to base.
When you make 400+ points, who cares about 5 points?
I copy
I like how you use that special part to put the water in the flower!
Thanks!
Damn that’s incredible.... Your programming was very neat even at 2x speed your transitions seemed smooth and well coordinated. Your cars were epic! I remember spending ages last year trying to make one for the shark, but nothing was as good as that. Mind if I ask how you did it?
Thanks. We have used two different designs for the autonomous missions. The first one we made was for the shark in Animal Allies and we used a pulley with a weight to pull the car along at a steady slow speed so the shark wouldn't fall over. This year, for the fountain and the flow, we decided to use rubber bands which wrap around the axle of the two back tires. We used rubber bands this time because we needed the cars to crash into the models to release or trigger the mechanism.
We just posted a new video that explains the details on the autonomous vehicles. Thx!
Thanks for the video Great job! But how do you get your robot to move to locations so accurately? The only way we have been able to do missions consistently is to have the robot follow a wall with wheels touching the wall at all times. Otherwise the robot never gets to the same exact location. Especially when you do any type of turn it never makes the exact angle turn We only do missions along the walls never could do a mission in the center of the table We built a simple robot to test this like the rover bot tried the gyro, but still it either does not go exactly straight That is all we are attempting to do now is try to figure out how to go 2 feet turn 90 degrees and move forward another foot it comes close to hitting the same spot but that's not good enough hen your trying to complete a mission. Any help on this topic would be appreciated Thxs again
First of all we have built our robot for accuracy by making stable and strong bonds, using hard tires, and supporting the wheel axels on both sides firmly. Even with all that we still have to constantly realign our position. We do this by squaring on lines, walls, and mechanical alinement on mission models. For example, on our second run, we use mechanical alignment by hooking our robot around the flower. In this mission we realign ourselves 11 times in the 38 seconds it lasts. Even with all of this our robot still drifts and doesn't go straight. This is why we realign ourselves so many times because the Ev3 robots aren't that accurate. Check out our TH-cam channel and you will find a video on how our robot is constructed and other videos that show exactly how we navigate around this years field mat. If any of your questions were not answered please ask again.
And don't give up! Thx
Thanks for the Video
Hi,Can I know how to install the cars and where to put them to start? Thanks
How much box did you use other than the basic box to install the robot and do you have a model to install the robot
Our robot uses some tires that are not part of the educational kit and 4 light sensors. Everything else is in the basic kit. We don't have a model currently but we hope to create and publish one. If you want to know more about our robot, check out the video about it on our youtube channel.
I am watching this during the second rounds
Thanks! Good luck!
How does the water collection work? I mean, it's amazing how it does it, but I just wondered how the robot can hold two water and a rain, but drop it. Is there anything below the water?
If you look close, you might see some small beams that hold the water up until they swing out of the way. They are geared together with the door so it all operates at once. It took us a long time to get this to work!
Amazing! Just a wuick question, did you take into account the -5 points from touching the robot at around 1:04?
Yes we did. We use this as a strategic touch to save time to do more missions.
Is the video sped up?
Yes. It's at 2x.
this is dumb, there is only 315 points not 435, and the tripod was not fully placed in, did you change the score??????????
Sherry Xu I take it you watched Hal's video? If you did, the reason they had "315 points max" is because that's the amout of points their robot alone can get if it did every mission perfectly. The max number of points these missions can total up to at all is 535.
The tripod does not need to be completely in the target, they just get partial score if some of it is. There is around a 500 max this year....
I assume they just got a partial for the tri-pod to save time
Yes, and also we didn't want to risk pushing the manhole cover out of the target!
