Vex Tower Takeover Wallbot Reveal and Custom Linear Slides

So, in the seven-ish hours before leaving for a Vex tournament, we decided to build a wallbot out of an experimental scissor-lift robot. We originally used Vex slides, but the leverage on them ended up causing the robot to split in half, so we had to come up with another solution. We could have used inside slides on both stages, but we did not have enough slides to build it that way. We tried looping zipties around the slides, but that only worked for a couple of the slides, and they tended to slip off of the slides and cease to help.
So we decided to go with another solution. Our solution was something we've been doing for quite some time, and I think it turned out rather well.

"it seemed to strike fear into the hearts of the competitors." Other Competitors: dear god its T-posing

[@calvinlittle7]

That's a T-pose in VEX robot form

F in the chat for all the teams who are trying to score points

[@micahscheaffer7182]

I feel honored that I got compete with and against you in a tournament. (I'm from 7686B)

[@KeplerElectronics]

Thanks! It was really fun talking with everyone at that tournament, it was neat seeing all the different designs from your guys’ region

[@slas_wrld8134]

this is awesome. rip teams that go against you guys

[@precast5613]

Was nice meeting you at the comp, hope to see you make it back for the next one

[@KeplerElectronics]

It was super fun talking with everyone there, I hope we can make it back for another tournament!

[@Roaming-Rob]

I made a pull apart wallbot back in gateway. Same approach you took here except with the older linear slides. It actually worked really well.

[@meepmeepme]

I always enjoy watching your videos, they're very informative and a great resource for beginning teams.

[@KeplerElectronics]

Hey, thanks! I try to make them as easy to follow as I can. Coming into Vex I really had to teach myself, so I try to make my content easy to understand and help those who don’t have a mentor grow into great builders and competitors.

Woah we both are studying kepler

@@charchuuu that's so crazy omg

[@charchuuu]

Yea

[@turretlez]

u seem familiar😐

[@kadencassidy3134]

When you drive forward the way you end up moving forward is because both sides end up fighting against each other moving all the force foward, so there is nothing you can do about that

[@samsara2194]

*remember how wallbots are legal for tower takeover?* Anyway, we had to build a super simple clawbot in a week. We didn't get time to even program autonomous. We pulled through in a few matches with some stackers. We put cubes in the towers, and they stacked. Other clawbots with us didn't work well. But it was very fun!

[@reactiongamerguy9537]

How did the two mothers that control how long the claws go didn't fall off?

[@aidanpatterson5345]

Why did you guys change your team number?

[@softsound1890]

I am extremely interested in buying a vex kit, what do you recommend?

[@KeplerElectronics]

Vex is relatively expensive, and it really depends on what you want... I would say that you should just buy the barebones V5 kit, and some structural components. I would purchase screws from another source, but standoffs from Vex are great. Purchase a number of axles and spacers, and that’s basically it.

[@noahboursier]

Not sure if you saw the NorCal RI3D, we made the stupidest wallbot possible. I'd say the best approach to this is make the massive deploy scissor as we did that is immovable once deployed because of its weight and length, but don't use an omnidirectional drive to deploy it. Our scissor could've been deployed by a conventional robot using a pin release passively linked to another system, and with a tether you get the best of both worlds so to speak, both a wall and a robot that can actively push.

[@jaiveersingh4981]

heyy our wallbot wasn't the *stupidest* one possible, I'm sure we coulda made it even dumber - I mean, cooler

[@NuggetDaChicken]

@@jaiveersingh4981 could u guys post a video of ur robot during a match or passing inspection pls? Some ppl on our team don't wanna believe ur bot is legal xD

[@kunalshah7539]

@@NuggetDaChicken that bot got dismantled because it was just a fun project made by a bunch of seniors who honestly know what they are doing and why do you think it wouldn't pass inspection?

[@fluffykittn]

I'm not entirely sure, but I do FRC rather than vex and all of these vex robots seem a lot smaller and less complex.

[@KeplerElectronics]

Vex is a lot more limited. You are limited to an 18” by 18” by 18” cube, and you have to use only approved materials (usually made by Vex, but not always). It has a few nice things, they are smaller, so most teams can afford to and have space for a field, and it levels the playing field a bit more, you don’t get quite the variance in robot cost like FRC.

[@---im4zm]

if i see a single wall bot at a competition i will break it

[@sammy13nation94]

Nice but it looks like a crab wich makes it awsome

Wallbot!!!!!!

[@exaultedflair2817]

When u have one Kit and a crap team In a state where like nobody competes....

[@aidanpatterson5345]

For the linear slides you guys could have used both inside trucks and screw them in together

[@KeplerElectronics]

This was our first thought, before realizing we didn’t have enough inside trucks and we had to improvise.

[@aidanpatterson5345]

Kepler Electronics ok, that would be a bit of an issue hehe. Good luck with your new robot!

[@Chrisontt]

It's good to stop tray robots

[@DreadNauts]

I think the reason why it kept driving onto opposing teams is weight

[@bennyride]

I thought you were datto a destiny 2 youtuber

[@braydentaylor6516]

Aren't you only allowed to come out 36"? Very cool bot btw!

[@KeplerElectronics]

For the past few years, yes, but this year, they decided to allow teams to build as wide as they want.

[@braydentaylor6516]

@@KeplerElectronics That is so broken I love it lmao... Can't wait to see that one robot that manages to push all robots to one corner and not allow any scoring what so ever

[@agliacci]

why did you not just put the scissor on the drive

[@KeplerElectronics]

Two reasons. The scissor wings were a bit of an afterthought, and also, it would make the robot even harder to drive if each side of drive was that far out. Not to mention that the scissor would have a lot of sag between the sides of drive...

[@agliacci]

@@KeplerElectronics it would have less sag then 3 points of contact standoffs lmao. Also u don't have to drive after u extend lmao

[@Zach929U]

Hmm.

[@Sammyhuman]

Isnt raming illegal? I seem to remember something about that

NetherTwins bruh

[@rindamico9446]

Nope. You can get DQed if you're not careful, but you can bump the other robots around

@@rindamico9446 oh okay

It was relevant to this video as it is a more refined proof of concept so I thought I would just post it for anyone intrested: kzbin.info/www/bejne/iKvRn5eantmfr5I
