Ctrl-Z Hydro Dynamics Robot 330 Points in 2.5 Minutes

See our most recent robot run, scoring 420 points at • Ctrl-Z Hydro Dynamics ...
This is Ctrl-Z, FLL Team 5831's Hydro Dynamics robot scoring 330 points in a 2.5 minute match. The first mission moves the Filter, drops the Rain, and completes Pump Addition and Flow. The second mission raises the Flower, removes the Broken Pipe, performs the Pipe Construction and Pipe Replacement. The final mission raises the Fountain, flushes the toilet to trigger the Water Treatment model, delivers the Tripod, delivers the Water Well, turns the Faucet and delivers the Slingshot containing dirty water and rain into the scoring area.

This is insane! Your robot is so fast, and yet so smooth, That second and third runs just blew my mind. Keep up the great work!

[@NitrousGasMan]

Thanks! We chose the large motorcycle wheels so that the robot would have a faster speed, although there is a trade off for accuracy. You'll notice that we have to accelerate up to top speed and slow the robot down before stopping to avoid wheel spin / skidding to ensure the run is repeatable.

Sick line following and line straightening

[@xanderdonald4576]

This is amazing! I was impressed by the thinking that since the slingshot was elevated above the target, it was in the target area.

[@CUSD95Coaty]

Great work! This is truly an inspiration to my own FLL team. : )

Hi there! I am from team Talos, and we competed with you in the provincials. I am sorry to say we both didn't advance to the internationals, but I had fun. Hope you did too!

[@xXXEnderCraftXXx]

So Complex.

[@theclueless11212]

Nice rubber band mechanism for the slingshot!

[@theclueless11212]

Nice! I looks like you could easily complete the rain in the flower.

[@NitrousGasMan]

Done! Check out our 420 point run at kzbin.info/www/bejne/jHPao5-hir6qbZI

Is there a way to get your Black line algain v

[@podha111]

At 0:49, how did you guys managed to make the robot do a smooth curve? We've been trying here at our lab, without any success... If you could help us, it would be great! :) - INSABOTS, from Brazil

[@danterus5565]

Wow! This si really cool. I was wondering how repeatable is this?

[@enochjoo1019]

awesome! Love the gear work, and what kind of wheels are those?

[@NitrousGasMan]

We use LEGO 11957 tires and 88517 wheels.

[@RebelRobotics]

Awesome! How does your robot go so fast and yet be so smooth???????

[@NitrousGasMan]

We use a MyBlock to control the movement of our robot. We input the starting power and end power for the drive motors and the MyBlock automatically smoothly accelerates or decelerates the robot until the target power is reached.

[@smn1129]

Holy crap! Those wheels are huge? Pls tell me where u got em

[@NitrousGasMan]

The motorcycle wheels were purchased off Bricklink from a person in Germany.

[@antoniocaetano1632]

Hello! I wanted to take a doubt, at the moment 0:38 of the video, his robbery goes back and forth. I wanted to understand the concept of this and how you do it! Very good theft

[@NitrousGasMan]

After driving the length of the table, the robot may have drifted slightly north or south. We square up to the black line at 0:39 to re-orientate the robot facing exactly east. There are light sensors next to each wheel at the front of the robot. Each motor moves forward until the corresponding light sensor sees white, then backward until the light sensor sees black. This is done repeatedly at progressively lower power until the power reaches zero. At this point, the robot is perfectly perpendicular to the black line.

[@osascostation2010]

Hi, can you share that code please?

[@professionalrelaxer652]

I believe in the game rules you have to use all lego part. Are those wheel lego (they don't look like it). But great job any way.

[@NitrousGasMan]

Those are LEGO 11957 tires and 88517 wheels. We chose large wheels for faster speed this year.

[@professionalrelaxer652]

My bad. Nice idea though and great run.

[@czef1r]

You are amazing! We will loss :P

[@gamingwithsathish1403]

Tell me program

[@AidanEu]

i wish i could see the code.

[@MyBACHCHE]

Could you please share your program?

[@atleaalstad1724]

Where is your team located?

[@NitrousGasMan]

We are a school-based team from Toronto, Ontario, Canada.

[@atleaalstad1724]

Did you win at the last year world championship in st. Louis?

[@NitrousGasMan]

Yes, we won Champion's Award at the FIRST Championship in St. Louis last year. We were definitely not expecting it, but the team had a really good Q&A session with the judges during the final callback.

[@atleaalstad1724]

I was there too, on team macgyver. This year i am going to detroit with a team called Septem. Looking forward to meeting you!

[@NitrousGasMan]

We remember team MacGyver from St. Louis. Congratulations to Septem for advancing to Detroit this April and we wish you the best of luck. We are competing in our provincial championship soon and we will see if we are fortunate enough to advance to an international tournament.
