Building a Lego ev3 Robot from Base Kit for FIRST LEGO League (FLL)

[@harini104]

Hi Zachary, I love your video it is so detailed and really helped me. Thank You!

[@itstheshivelys1880]

this is a very good robot

[@yahoo5726]

I love this man’s vocabulary usage

[@ROBOTICACADEMY]

Hello Zachary, sorry if my english is not good but I use google translation;) I am a teacher for 10 year olds and we decided to participate in the First Lego League this year. Your advice and help are very valuable to us. It's really a good base for us to work. thank you very much

[@ZacharyTrautwein]

you are more than welcome! It's exciting that you participating in FIRST LEGO League! It's one of the most valuable experiences for a student!

[@ROBOTICACADEMY]

Thank you very much. We are Belgian and my primary school students are very motivated. We've worked from your videos today to better understand the mechanisms to use for missions

[@NoVaCXG]

Thomas Luo just go with it. I’ve seen FLL teams where the mentors do all the work while the kids lolly gag and act like they don’t get what they were doin.

[@robertcameronjones]

Thanks for posting. The problem with the video is the wheels. They are not standard, nor are easily available. This sets up a problem using the standard EV3 wheels where the color sensor is so close to the surface, it doesn't function. This makes this design not practical for many. I do thank you for explaining the attachment mechanism. That should be useful.

[@ashleytinker9801]

Very Helpful Video, Thank You And Please Continue Making Tutorials!

[@jiangzhu5214]

Your tutorials are very helpful. Thank you!

[@ZacharyTrautwein]

You’re welcome! Check out the new FLL robot with Spike Prime! A build video of that robot will be available in a week!

[@seemarai5310]

i can't stop my fingers to give this video a 👍. it's sooooooooo good

[@bhavithjasti4225]

Thanks Zachary Helped A LOT!

[@xzistor]

Very informative video! Thanks! :-)

[@ZacharyTrautwein]

Welcome!!!

[@davidshin4456]

awesome video!

[@jowoodcock5640]

Thanks! Very useful info!

[@ZacharyTrautwein]

Welcome! Stay tuned for some cool City Shaper content!

[@batoolk3abnah599]

Thanks for you l like your video you showed all the pieces that are very important to start to make a Robot 👍👍

[@Gato_Kun_7]

thank you for your work, and that is a great ring you wearing

[@DavidDMuirYT]

Brilliant! Thank you. We are still trying to work out how to change attachments and a "Universal Attachment Mounting System" using the picture frame sounds like exactly what we are looking for. This video says (around the 27:50 mark) that you will you explain attachment mounting in another video. What video should I be looking for? Thanks again.

[@AjayTanikella]

Zachary. Thanks for the video. Nice work. What sites do you recommend to buy the large wheels and other EV3 parts?

[@harini104]

Can you please make a program tutorial for this robot please?

[@CoCo3YouTube]

ty very helpful

[@ZacharyTrautwein]

Glad it helped

[@emilypineda3283]

Thankyou very much This is gonna really help my team with tips//Were Kinda begins in making the robot and half of my team probably wouldn’t have been able to come up with this stuff

[@ZacharyTrautwein]

Glad this could help!

[@wilsonnewsnetworkwnn2114]

you mentioned that you did videos about extensions but I can't find them. Can you post a link? We built the robot but are stumped as to how to connect extensions - especially active ones.

[@Ninoo17]

On the timer 4:04 why didnt you use the blue peg that is double sided isnt better than using the beam ? Btw Love your video 🙌🏻

[@heatherphillips7823]

Thank you for this! So helpful for my teams.

[@ZacharyTrautwein]

+Heather Phillips great!

[@rahuldas4722]

I like this robot

[@rohankolala332]

you should use the dog ear mechanism but still, this is great

[@marilynmiles2231]

I ordered the extra motor and sensor..Great Instructions..I still want to find the skinny wheels

[@ZacharyTrautwein]

Look on bricklink.com, I believe they are parts numbers 2902 and 2903

[@georgequade4594]

Would love to see the parts list/numbers for this. My son is interested now and we are going to a Lego basic robot session that our local library is putting on. I thought this could give him some intro as well. Thanks in advance!

[@secomonos2005]

Beautiful design, please show some plugins attachments

[@csgaming5263]

Hi thank for help me my compitition on August on Lego ev3. Robot

[@christinelong5369]

Hi! Amazing ressources for a beginner like myself. Do you have a place where I can find the codes for the different missions? Just to give me a few examples on how to do them. Thanks for your fantastic work!!!

[@ArtistisMe]

This isn't from a true base kit, as part way through building it you mentioned a second medium motor and a second light sensor. The base kits only have one of each. I didn't know you could add extra motors or sensors that are not available in the base home or education EV3 sets, if using for FLL. I'm I wrong? So, now I've taken it to pieces to find a better solution maybe that uses no more than whats actually supplied.

[@ZacharyTrautwein]

Hi! Very true. I do mention adding an extra medium motor and an extra light sensor. However, in order for this particular robot to complete the robot games for FLL you do not need to add the extra light sensor and motor. As for your question about using more LEGO that is not included in the base Education kits: The Challenge guide (firstinspiresst01.blob.core.windows.net/fll/2019/FIRST-FLL-2018-19-ChallengeGuide-A4.pdf)says: "R01 - ALL EQUIPMENT All Equipment must be made of LEGO-made building parts in original factory condition. Except: LEGO string and tubing may be cut shorter. Except: Program reminders on paper are OK (off the Field). Except: Marker may be used in hidden areas for identification." And "R03 - MOTORS You are allowed up to FOUR individual motors in any particular Match. • You may include more than one of a type, but again, your grand total may not be greater than FOUR." So you do not need to stick to ONLY the parts provided in the base Educational sets. I hope this provides some clarification. Thanks for the dialogue!

[@susanmagasi175]

Hi Zachary, Love your videos. Any tips on how to keep the 3-wheeled robot from fish-tailing? We build a base but still end up in a different spot every time. Thanks!

[@mbarnett667]

Thanks for the great video, We cannot locate the "Lama" that looks like a L with 4 pegs. Did you put this together or did it come with your kit. Thanks

[@prungdin]

thank you very much

[@rodneylw10]

Hey Zach, I am trying to find the wheels you used what size are they 100mm? Not sure. Thanks.

[@d.c.brittneybogart6687]

Where do you get the "llama" pieces? I didn't have any with my kit, but we really find your design and tutorial helpful. I would love to be able to pick some up from somewhere if you can point me in the right direction. Thanks!

[@ZacharyTrautwein]

You can get some of those pieces here: www.bricklink.com/v2/catalog/catalogitem.page?id=78119#T=S&O={"iconly":0}

[@d.c.brittneybogart6687]

Thank you so much! My boys just competed in their first robotic competition after having learned a lot from your videos! None of us had any idea of what to expect at the competition. We also didn't have all of the pieces to make the robot exactly as they wanted, but they still placed 4th out of 12 teams. I thought that was a fairly good result for their first competition and being very knew to the whole robotics world. Thanks for all of the helpful information and videos!

[@ZacharyTrautwein]

d. c. brittney bogart you’re welcome!

[@carmenbetineli1076]

The Light sensor dont read the black line

[@JasonLLC]

Hi Zachary. Can you tell me the lego part# for those wheels? I'm in AlCo at Cash Valley. We're kinda behind getting our bots made.

[@ZacharyTrautwein]

Hi Jason! It’s exciting that y’all are getting your bots together! They are actually hard to come by these days. I believe this link will a post on bricklink where you can grab some.

[@hemamerchant17]

Hi Will it be ok if we used different wheel ? I have a motocycle Wheel but is much bigger than the one you have. Its throwing of the robot.

[@ohmingfeng9351]

The wheels came from the original lego mindstorms rcx set

[@praful6668]

Hello, i am from india and I need help to make a robo to finish FLL INTO ORBIT mission. Can you send me a PDF file for making a robot to slove INTO ORBIT mission

[@KimboH55]

How many kits you got? Only get 2x 3x5 Ls and 1 mdm motor per kit. Out of blue pegs too.

[@pequodexpress]

How easy is it to remove the brick to replace the AA batteries for the 31313 Home version?

[@TARamkumar]

Awezome Too good

[@PatrickSturgill]

What kind of container is that? It looks pretty perfect. Thanks.

[@ZacharyTrautwein]

For the pegs? It’s actually a fishing tackle box. I store all my LEGO in a segmented tackle box. You can get them at Walmart for a few bucks! They’re fantastic!

[@ROBOTICACADEMY]

Hello Zachary, despite the power of 30 on the engines, the direction is very straight. The robot turns slightly to the left. Over a distance of 1m, it deviates by 2-3cm. Is this normal? Should we work on different powers (for example 30 and 30.3) or with the sensors? What do you advise? thank you in advance

[@ZacharyTrautwein]

hi! I've found 2-3 cm does not seem unreasonable. LEGO motors have a ton of "play" in them. I advise my teams to use sensors to adjust themselves. I also advise them to use the walls to "reset" the robot mid runs.

[@ROBOTICACADEMY]

Thank you very much for your advice. We will get back to work;)

[@FactsNotCap]

That robot looks like my first robot

[@pakistansoccerstudios9414]

Hi Zachary can you make a tutorial on the program of this bot...plz it urgent.

[@lukasgrm4031]

Its good

[@hashem_hak653]

thakes pro god joop

[@fretmenerds7920]

i don't have 2 light sensors what do i do

[@user-yy3tj2tq8w]

Jude Finch me too

[@hydrogenhead]

Pick which side to place the sensor if you only have one. The placement of any sensor depends on the task for which that sensor is used. What mission is the robot trying to accomplish? What is the best way to accomplish it? These questions will determine where to place the sensor.

[@harini104]

Does this require two medium motors ?I have one medium motor in my EV3 kit

[@ZacharyTrautwein]

Hi! It does not “require” two of them. You can use just one if you like then add another one later if you get a second medium motor!

[@ZacharyTrautwein]

@Jamie Marak hi! I would not use the one on the inside for the front. It’s the most useful!

[@littledragon5642]

hello I'm a 12 year old making a robot for a competition. I am my groups programmer so I don't really build buI but I think I shall build a little and use your design but morph it for my use. THANK YOU SO MUCH!!!

[@abhishalkochhal272]

Piggy cool

[@claudiaachutti5813]

I don't have 2 light sensor and these kind of wheel... :(

[@liammee6621]

in the core set starting kit there is only 1 light senser

[@donnarobinson5417]

First year for our school, very much a rookie but love your design however, we only had 1 color sensor and 1 medium motor how do we substitute for competition? Is it allowable to get additional parts?

[@ZacharyTrautwein]

+Donna Robinson yes! You can get color sensors and medium motors from Bricklink.com or amazon.com!

[@variance234]

what if you don't have 2 color sensors, then what do you do

[@exzotikgaming1592]

Thx

[@JklesChay]

AHAHAHAH IM NOT THE ONLY ONE THAT CALLS THAT A LLAMA!

[@MohamedHassan-fb8pn]

Hi friend Can you share the programming of this robot that makes it doing all missions in fll

[@davidshin4456]

totally did not dislike heh

[@davidshin4456]

I liked!

[@fllteamsintra8015]

hi, can you make a video on how to collect the sludge and the big water , thank you my channel is called FLL TEAM SINTRA

[@septercat]

very good I know you fixed thank you very helpful to me but I need to destruct who I build from the old version(when your camera has a problem then shut down) so thank you very well I event do 10 accounts to supcribe to your channel lol :)

[@danbuskyfamily]

Hi Zachary, We got into minute 17 and realized that our kit only came with one sensor. Should we have received two? Thanks.

[@ZacharyTrautwein]

+Pamela Danbusky Hi! I believe that only one color/light sensor comes in the base kit. You can browse amazon.com for a EV3 color sensor, or if you do not want to buy another sensor, I would recommend that you put the light sensor on the front right of the robot!

[@danbuskyfamily]

That is VERY helpful, thank you so much. The kids feel like you are a third coach already....very much appreciated!!

[@ZacharyTrautwein]

+Pamela Danbusky no problem!

[@mrbendover2072]

where are the wheels

[@shruthisriram6275]

WHY DIDNT U USE DA LONGER WIRE!

[@vikhyatduddilla2174]

at 23:50 it wasn't aligned with the other side

[@niffy561]

my kit only came with one light senser

[@ZacharyTrautwein]

If you want you can grab one here! www.bricklink.com/v2/catalog/catalogitem.page?S=45506-1&name=EV3%20Color%20Sensor&category=%5BMindstorms%5D%5BEV3%5D#T=S&O={"iconly":0} Or just put a #3 beam in it’s place.

[@michaelcai6191]

its not a light sensor,its a colour sensor!!!

[@sarahludwig6160]

the 'Lama' is called donkey

[@abdullahi7575]

I wanna start building what set should I start with

[@ZacharyTrautwein]

If you haven';t already bought something, get a SPIKE PRIME kit!

[@donnarobinson5417]

Have you built an ev3 with real/only base kit parts, That will work with 2017 hydrodynamic challenge ?

[@ZacharyTrautwein]

+Donna Robinson hi Donna! So, every part with the exception of the wheels on this robot is available in the base kit. Maybe a few of the sensors as well. You can do the Hydro Dynamics game with one color sensor on the front of the robot just fine. If you’d like to build one of these robots you can hop on bricklink.com and look up part numbers 2903 and 2902. Those are the wheels and tires. You can pick some up for a few bucks! We’ve found these wheels to be far more accurate and consistent. I would recommend the upgrade for the small price! Let me know if you have any questions!

[@donnarobinson5417]

Zachary Trautwein , I tried to order the tires only to get a no information fearful young mrn ontd= hoeeillvtoy toj3ertain funds. I just want the tires

[@evanbenfer3568]

do you have a group you can sigh up for and can you use smaller tiers

[@ZacharyTrautwein]

I’m currently working on a design for smaller tires, but the big tires might be worth the few dollars they cost! They add a bunch of accuracy!! What do you mean a group?

[@user-yy3tj2tq8w]

Am I the only one that doesn’t have a 2nd motor??

[@legoinventions2340]

Just like this Count:9999999999999

[@chess-analytical]

Can you make you for a home edition

[@ZacharyTrautwein]

Home edition? What specifically?

[@joeywilson.]

Can you make your attachment videos not private like they youest to be

I'm sorry but I don't speaking English I don't know what are you writing in the video.😶😉

[@lerixoff5362]

go and learn English then, what's the problem ? :D

[@anshulpulliwar6897]

i dont have the pieces pls buy :)

[@rohankolala332]

at 24:12 what beam hole number is that? 15-hole? 13-hole, or 11-hole?

[@ZacharyTrautwein]

It is a #15 beam.

[@rohankolala332]

thx

[@collinkeith4250]

Where did you get your Legos?

[@ZacharyTrautwein]

Thanks for asking! I get all my LEGO kits from www.legoeducation or from amazon. With the exception of the wheels. I order those from brick link.

[@donnarobinson5417]

Do you have a build out based upon what is in the kit to compete with?

[@ZacharyTrautwein]

+Donna Robinson all parts in the video are allowed in competition. The only parts that are not in the base kit are the wheels and tires. You can find them on bricklink.com. Part numbers 2902 and 2903.

[@donnarobinson5417]

With attachments

[@evanbenfer3568]

can you build this robot with the core set?

[@ZacharyTrautwein]

Evan Benfer yes! All except for the wheels and the extra top medium motor. Let me know if you want part numbers!

[@hthotakura]

@@ZacharyTrautwein Hello, can you let me know the wheels you used on this robot?

[@billutube1231]

What size wheel is used for this build and what is the part number?

[@ZacharyTrautwein]

its 61.6mm wheel with a 81.6mm x 15mm tire. They are titled as "motorcycle wheels". Part Numbers: 2903 / 2902

[@ZacharyTrautwein]

You can find them on bricklink.

[@billutube1231]

Thanks for your prompt responses. Very helpful. Nice build.

[@jamiebradshaw9247]

Zachary, how to you attach the universal square attachment?

[@wakandadorolo9053]

Im familiar with that

[@rjsahm5880]

how do you get those wheeles

[@ZacharyTrautwein]

The are wheels that came with a Mindstorms kit years ago. They are we also sold in a technics motorcycle kit. You can get them at bricklink.com. Part numbers 2902 and 2903

Zachary Trautwein oh ok cool, it just looked like you were in a school office so I automatically assumed you were a school principal

[@taxevader9859]

Also are theses robots fun to play with, I have always wanted an ev3 unit or an nxt but frankly I'm a kid so I don't have the money. So are they fun?? And are they hard to program??

[@ZacharyTrautwein]

So fun! and super easy to program. I have some videos where i teach you how to program, you can go check those out and see how its done! Maybe find a FIRST Lego League team to join in your area and then you can experiment and use EV3 to solve problems and challenges! So much fun!

[@taxevader9859]

Zachary Trautwein ok, I'll go look into that and watch the programming videos. Thanks!

[@rohankolala332]
