It's been 3 years and this is still a legendary robot. Thanks a lot for inspiring me and my team, I remember back in the days we saw this video soo many times trying to fully grasp the strategy behind this robot. Thanks, really, in the next year we won the Brazil's Championship and were classified to Houston. What a ride

[@ivrismouha4739]

I feel the same way.

[@harryhe2078]

Your robots are really amazing!We learn a lot from you guys. Congratulations on the winning in Estonia international !!!

[@RebelRobotics]

I have been waiting for this video for a LONG time! Great job! This is insane! Best strategy ever!

[@medeiapsyche]

Danke!!!!! Thank you very very very much for sharing your work with us! It's so nice to meet you in person. You guys are so inspiring and amazing! Hope to see you soon!

[@brickSAPplied]

Thanks, do you also participate and what's the name of your team?

[@medeiapsyche]

brickSAPplied Yes! In EOI. I belong in a team named DLSZ BrafeNHS from the Philippines.

[@josewilson-ez2dk]

Very good work, what I liked most about your robot is that he is simple but effective, u didn’t built giant structures, sometimes it was just a single piece that made 20 points, beside this, the programming is awesome, he isn’t just accurate but he is fast, very impressive

[@AstroPlays]

Mad respect to this. Good luck in Into Orbit!

[@frankheitmann-costa869]

Glückwünsche auch aus Frankreich ! Wir sind 2. geworden und fahren auch nach Tallinn. Ihr werdet viele vom letzten Jahr wiedersehen. Ihr habt einfach den Dreh raus ! Saubere Arbeit !!!

[@brickSAPplied]

Danke!!! Glückwünsche zurück und cool, dass man sich in Tallinn wieder sieht ;-)

[@WharfRatsFLL]

Wow! Y'all are back and you're getting perfect scores, again! Congratulations!

[@kipabots9223]

WOW! Amazing robot and attachments! We are also going to compete in Estonia Open International. Good luck and see you there!

[@brennnessel8091]

Look forward to seeing you at the EOI

[@ananyasaridena1900]

AMAZING WORK YOU DID PERFECTLY

[@teammindfactory]

Wie immer perfekt gebaut, programmiert und gelöst, WOW! War sehr spannend in Aachen, hoffentlich bis im nächsten Jahr ;)

[@brickSAPplied]

Danke ;-) Euer Robot-Game war auch ziemlich beeindruckend. Ward glaub ich die einzigen, die dran gedacht haben einen Trichter zum Zielgebiet zu bringen. Auf welchen Wettbewerb geht ihr? Diesmal doch das World Festival?

[@goetherobotx2209]

brickSAPplied Was meint ihr mit Trichter wenn man mal fragen darf?:D

[@brickSAPplied]

Goethe RobotX Schaut euch mal die erste Mission an. Mit Trichter meinen wir, dass die große Wassermenge dann sicher im Zielgebiet landet. Kann ja ohne irgendeine Hilfe doch ziemlich oft daneben landen... (Ist aber tatsächlich eher eine Schräge, als ein wirklicher Trichter)

[@aymo.]

Bewundere euch echt wie simpel aber extrem effektiv ihr eure Aufsätze gebaut habt. Echt Respekt. LG Capricorns

[@brickSAPplied]

Habt ihr vor auch noch ein Video hochzuladen?

[@FLLTechnoMonkeys1491]

THIS IS SO A-M-A-Z-I-NG!!!!! You are the best team everrrrrr

[@salihakgul341]

Dude this is the best robot ı have ever seen. I wish we could met in houston :/

[@bendikskarpnes1834]

Very, very impressive! We, Team Gosen will also attend at FLLOEC in Tallinn :) We look forward to talk to you :) Best regards Team Gosen (A team of two from Norway)

[@brickSAPplied]

We are also looking forward to meeting you :)

[@ftcteamcrashtest3729]

This robot is a thing of beauty. We have spent two years trying to figure out how to get smooth acceleration and deceleration. How did you do it? Thank you!

[@brickSAPplied]

FLL Team Water Works Thanks! Our acceleration is actually very simple. Every loop cycle the speed gets a bit higher until the needed speed is reached. For deceleration we look at the distance, the robot still has to drive. When its time to slow down, the we set the speed proportional to the distance. When the robot has finished the movement, the speed is 0...

[@ftcteamcrashtest3729]

Thanks! We have tried a similar approach but there seems to be a small pause in between each "step" in the acceleration that creates problems. Could you share which motor control blocks are you using to control the robot while you are accelerating and decelerating? Are you using the "unregulated" motor control blocks?

[@brickSAPplied]

FLL Team Water Works Are you using several loops parallel? We also use unregulated motor blocks, but your problem seems to be a problem of performance. Maybe you can just count the loop cycles and devide it with the needed time after the movement. This value should at least over 100. A performance-killer are for example parallel loops...

[@ftcteamcrashtest3729]

Thanks again! It turns out the problem was using movement blocks that had a distance instead of just turning the motors on and and watching the distance with a motor sensor before going on to the next movement. Once we changed that we can now get smooth acceleration and also smoother changes between different movements. Now we need to see if we can make it as accurate as the old way...

[@alexwang2932]

AMAZING!!!! Hope to see you at World Festival!

[@brickSAPplied]

Alex Wang We actually got the opportunity for the World Festival, but this year we'll go to the EOI in Tallinn, Estland...

[@AleMonti_YT_Channel]

Really? In your region you can choose were to go? If you left the ticket for Detroit, which team I will meet there? :D

[@brickSAPplied]

The qualifikation system is a bit difficult. The best team from a country gets a ticket for the World Festival (Germany gets two tickets), but there are also 4 tickets for the OEC in Debrecen (Hungary) and also 4 for the EOI in Tallinn (Estland). Now first of all the champion can decide between these competitions and depending on the country and the ranking of the team you can go to different competitions. We won the overall second place and only the Goethe RobotX were better from Germany, so we had the oportunity for all of these competitions. I know, that Goethe RobotX and mindfactory will be at the World Festival...

[@tmlrobotics5446]

Well you have already achieved max points and you still have time before the competition to work... What's the next step? Make the robot end in base ;) Great job!

[@brickSAPplied]

TML ProductionsTM Good idea ;-) We want to make some things more reliable, but at the moment we don't think about big changes

[@tmlrobotics5446]

brickSAPplied Okay :-D but honestly, I think the world would explode if a robot better then this ever entered a competition.

[@RebelRobotics]

Agreed!

[@LegoHJ]

Great ! Congratulations :-D

[@theclueless11212]

Can’t wait to see how you blow my mind again at worlds

[@theclueless11212]

Wait you didn’t make world’s? What does EOI stand for?

[@brickSAPplied]

We had the oportunity also for the World Festival and the OEC (Open Europeen Championship) in Debrecen/Hungary, but decided this year for the EOI, which means Estonian Open International... Also because OEC and World Festival collided with other events

[@theclueless11212]

Interesting strategy and organization of missions

[@HAL9000Robotics]

Great work as always! How are you going to improve for EOI?

[@brickSAPplied]

HAL-9000 Robotics We'll try to make some things more reliable, but we won't make big changes

[@arefhafza4070]

U prob won't work heaps on the robot, u should pump out the project

[@brickSAPplied]

You are right. So far we did already a lot for our research project

[@HAL9000Robotics]

@brickSAPplied what is the date for the EOI?

[@brickSAPplied]

It's from the 6 to 8 June, so in 42 days, 19 hours and 33 minutes

[@joaopedrocamargobatista8438]

Woooow, very impressive! How do you make a line squaring so accurate and efficient? Do you make any special calculation?

[@brickSAPplied]

Thanks! You are right, we calculate the deviated angle and afterwards we can correct it during the next movement using the gyro sensor

[@joaopedrocamargobatista8438]

@@brickSAPplied Thanks for the answer! Congratulations on the winning in the Estonian Open! Are you competing in Into Orbit?

[@brickSAPplied]

@@joaopedrocamargobatista8438 Thanks! We are not competing this season, but we'll be referees or volunteers and some of us are now mentoring some other teams

[@charlesalmeida264]

@@brickSAPplied But, how do you calculate the angle of deviation? Are the color sensor used or only the gyro sensor? My team is having difficulty to do the line squaring. Can you help us, please?

[@brickSAPplied]

@@charlesalmeida264 For the calculation we only use the color sensors and the rotation sensors, but while crossing the line and for correcting the deviated angle afterwards we also use the gyro sensor. The calculation is difficult to explain. Maybe you can give us a email adress, so we could send you a picture... Anyway a short explanation: The robot drives straight until one of the sensors detects the black line. Then the rotation sensors measure the distance until the second sensor also detects the line. Because you also know the distance between your color sensors you are now able to get the deviated angle by using tangens

[@wut9282]

Did you guys qualify for worlds in the 2018 to 2019 season

[@camsweetgrass5317]

Wow! Very efficient run! Would you mind sharing what kind of MyBlocks did you use in the program other than distance and acceleration? Also could you, please, recommend any good source for acceleration/deceleration my block tutorial? Everything I saw only covers acceleration. I wonder how others do such an accurate deceleration. Thanks in advance!

[@brickSAPplied]

Cam Sweetgrass We use in the end six my blocks to navigate. For example one to drive straight with the gyro sensor. This includes acceleration, deceleration, different ending conditions (distance, time, line) and some other features. We also use my blocks to align at lines, follow lines, turn with one or two wheels, drive arcs and one to drive straight and arcs with the rotation sensors. All these blocks also have the features as described. We didn't saw any tutorial for the programming, but maybe you'll unterstand how deceleration can work: The problem is, that you need a certain distance to decelerate and that the speed has to be always the same at the end of the movement. If less distance is left the robot has to drive slower, so the speed has to be proportional to the distance the robot still has to drive... Was it helpful?

[@andreassrensen3972]

@@brickSAPplied so you don't lock the engines after a certain distance??

[@tmlrobotics5446]

@@brickSAPplied I am just curious since you mentioned it. You say you have a ramp up/down myblock that can finish at a line. Do you decelerate after the line is hit?

[@brickSAPplied]

@@andreassrensen3972 At the end we also lock the motors, but before we decelerate smoothly

[@brickSAPplied]

@@tmlrobotics5446 For lines we actually don't activate the deceleration. Therefor we declerated just before the line to 30 or 20

[@Yal3wadhi]

Guys you are amazing but you didn’t got 535 you got 545 points because the opponent thought the big water in your water collection

[@brickSAPplied]

Thanks! You are right for the international rules, but unfortunately in central europe we don't get the 10 points for three big waters, because one of them isn't touching the mat...

[@Yal3wadhi]

But it’s in the target 🤔🤔🙄

[@brickSAPplied]

Yousef Alawadhi firstinspiresst01.blob.core.windows.net/fll/hydro-dynamics-challenge-letter.pdf But here it also says "...so it is touching the mat in the Water Target."....

[@epiclevelwarrior]

There are 2 big water touching the mat in the target. The water stacked for the bonus is not touching the mat. That is why the score here is 535 not 545 and, to my knowledge, that should be the same in every region since it is clearly stated in the rules and has not been changed by any update. I can confirm we ruled that way in my region (North Carolina, USA)

[@brickSAPplied]

Sam Ok, thanks!

[@tommi1654]

Wieviele My Blocks benutzt ihr und was machen sie?

[@brickSAPplied]

Insgesamt benutzen wir 18 My-Blocks, aber die meisten sind nicht direkt zum Fahren, sondern nur Untermethoden. Unsere 6 Move-Blöcke benutzen wir um geradeaus mit Gyrosensor zu fahren, für Bögen mit Gyro, Drehungen auf einem oder zwei Rädern, um uns an Linien auszurichten, Linien zu folgen und um geradeaus oder Bögen mit den Rotationssensoren zu machen. Die letzten beiden verwenden wir diese Saison aber gar nicht. Alle Blöcke haben natürlich noch ein paar andere Funktionen, wie zum Beispiel sanftes Beschleunigen und Abbremsen...

[@tommi1654]

brickSAPplied danke für die antwort! Denkt ihr es gibt punkte in Robot design wenn man so unterprogramme macht?

[@brickSAPplied]

Tommi Es gibt den Punkt übersichtlich und für jeden verständlich oder so ähnlich. Dafür können Untermethoden ganz nützlich sein, aber da muss man natürlich aufs Programm schauen, in welchem Umfang das sinnvoll ist. Prinzipiell aber auf jeden Fall keine schlechte Sache

[@veebhushah9667]

what does SAP stand for?

[@brickSAPplied]

Frozty SAP stands for "Systeme, Anwendungen und Produkte in der Datenverarbeitung" (systems, applications and products in data processing). It's a very big software company from Germany...

[@veebhushah9667]

ohh ok were you sponsored by them?

[@brickSAPplied]

Yes, SAP sponsors a lot of teams. They all have SAP in their names...

[@ryanguo9300]

How did u guys not get 1st place in robot performance?

[@brickSAPplied]

We reached the finals and got one of the highest scores, but unfortunately the first blue pipe line went wrong in the first final, so the rest of the mission also failed and Caroaces and Goethe RobotX got more points...
