Hi Zach- can the EV3 be modified for the 2023 superpowered challenge?

[@albertesparza4681]

Hi Zach, I followed your instructions on the robot build is there a tutorial on how to build the attachments for the 2022/2023 missions.

[@mstroud7507]

My students have built this robot but are having some problems with the gears being strong enough to hold up any type of weight on the attachments... Suggestions? (I'm not very savvy when it comes to engineering...)

[@MrsBlack-js9en]

Hello wonderful videos however I was wondering if you could make a video on how to build the square base that goes around this model and how to build the removable attachments. Thank you

[@rohankolala332]

nice upgrade suscribed

[@astubblefield6297]

Great video and I’m loving the cable management. It looks like it’d be a huge challenge to get the brain and battery out. How did you accommodate for this challenge?

[@ZacharyTrautwein]

It actually comes out pretty easy. If you have ever experienced taking them out on the booklet Bot, it’s about the same. Taking 3 or four pegs out and it clips off.

Zachary Trautwein please do a demo

[@donnacornelison7908]

Where do you get the bigger wheels at?

[@ananyabhattacharjee6251]

really helped

[@ناصرالعمران-س3ذ]

NO IT BAD

[@donnarobinson5417]

Also, it looks like you changed the gears are they grey and smaller or does it matter? If I am modifying I want it to be effective.

[@ZacharyTrautwein]

So our gear ratio is something that we have found work for us. Your more than welcome to use what we use, or find what ever you works for you!

Hi I subscribed

[@donnarobinson5417]

Okay so my axle kept falling out did you use one with a flat head in between the 2 chassis (picture frames)?

[@ZacharyTrautwein]

Yes I am using one with a flat head on it. There is one that is a dark grey and one that is a dark tan-ish color.

Where is the video for the original build?

[@rohankolala332]

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

[@QuietLycoris]

Just to know are your wheel NXT set wheels or a separete lego technic set wheel?

[@ZacharyTrautwein]

+Michael Abam I have a video on how to build the robot, take a look on my channel! Also the LEGO wheels are separate wheels part numbers 2902 and 2903. Maybe search for them on bricklink.com

[@shrihan3450]

Where is the universal attachments plate on the robot? Been trying to find it

[@ZacharyTrautwein]

Shrihan Vijay Hi! Check out pipe removal mission video. I build one in there.

[@shrihan3450]

+Zachary Trautwein Thanks! My team has built your filter attachment, and now we can get more points in less time!

[@donnarobinson5417]

There are more black pegs too, right

[@ZacharyTrautwein]

Yes there are!
