Why I Build Robots Without Wheels
Вставка
- Опубліковано 29 вер 2024
- Shea Waffles Johns built Big Cookie and is the driver of Depth Charge, both robots are unique in that they have no wheels and move by the vibration of bristles attached to the underside. It's very difficult to control, but that's just how Shea likes it.
In the latest episode of This Is Havoc, find out why she says No to wheels and prefers the seemingly impossible to control bristle drive instead through her new robot Big Ccookie.

Control? Aggression? Driving in straight lines? Screw that. GIVE ME MOAR WEAPON, *MOAR CHAOS.* Just like Deep Six and Depth Charge, even if event organizers and maintenance crews hate all-weapon bots the sport would be so much less fun without them. Kudos to Shea for creating this one.
We love all weapon bots.
@@NHRL eh
@@NHRLI see that you have the minimum amount of flair on... don't you want to express yourself😂
Non-wheeled locomotion, like flamethrowers, may not always be the "best" but it'll always be the coolest.
Big cookie seems to be effective
Is that announcer Pete Gustin?
Non-wheeled robots will always be some of my favorite bots. They tend to have some of the most creative and entertaining designs and Big Cookie is a perfect example of that.
Well soem are sucky liek the battle bot Rex
It was lame as hell
This is literally my best friend in robot combat and to see her go from 1 lb concept to 30 lb monster has been so incredible. I adore this robot so much and I can’t wait to fight it with any 30-lber I end up building.
WE LOVE BIG COOKIE. IF YOU HATE IT, BLESS YOUR HEART.
I read the title as "Why I bully robots with no wheels" and was expecting an aggressive short essay on the superiority of wheeled robots lmao
Hopefully you weren't disappointed...
@@NHRL you should make a video like this but make it real dark and there is some guy sitting by a fireplace reading about their hatred for nonwheeled robots lol.
Big Cookie left such a huge impression at the January tournament. I'm excited to see what Shea does with it next.
Many impressions on the floor too 😂
Impressions, dents, cracks, shrapnel....pity the floor, as much as any robot opponent (and sometimes the sidekick!)
Love the simlicity of it. Just raw power. A golden bayblade of destruction.
Its a spinning death tank that wobbles. Sounds like an excellent plan in my book! I see the beauty instantly
I love to see this type of content, I think its what the sport really needs to grow.
why did the vert get an unstick in the first fight? Big cookie worked to deliberately stack them, isnt that a legitimate strategy?
Oh hey, I’m a big fan of Jasper! At NHRL, every robot gets one free unstick from the house robot. Builders typically ask for the unstick, which is designed to keep matches going longer, and eliminates early count-outs due to a weird bump or a bit or bad luck.
@@lukeb0t Thank you, that is very kind of you to say. That's a pretty cool rule.
Big cookie was just Looming Death while the minibot was playing hunting dog
Gotta appreciate welcoming a new style in. Bring it on! It takes a great mind to design, test, and bravely put the creation in the area. I see good things to come.
Boom!
Awesome vid,love shea,she’s awesome and her bots are too! Cookies such an awesome bot,love me a walker bot
I love somebody who recognizes their own weaknesses (I also struggle with wheel control lol) and uses creativity to seek a different path. I love da cookie 🍪💖✨
Interesting design philosophy and robot! Thanks for sharing!
Glad you liked it!
Cookie!!!!! Such an amazing bot and team!
This woman is fun and quarky and talented she has good energy and smart !!!! Awesome
I was skeptical about the robot, but damn..... Powerful robot, good job big cookie creator's.
Sparkle Sparkle
With further iteration this could be more than just interesting
Big Cookie vs Deepth charge ;-P a fight prone fot a double knock out 4 refusing to fight or big cookie will win just for an attack by the mini bot?
I love Big Cookie
More engineer showcases please! I love seeing how these bots are built.
This is so cool!! Go big cookie!! You got a fan for sure! Can’t wait for the next iteration!
Good concept, a little lackluster in the mechanical side but it's a first year robot.
The minibot was really a great team player, ample speed and great driving!
Perhaps the uneven bristles made the main bot dip too much at high rotation of the main weapon?
I understand that they want some dipping, but perhaps they got more than they bargained for?
The two stops in the last 2 fights, was that a mechanical failure of the gearbox they mentioned wasn't made for their possible rotational speeds?
Good efforts nonetheless, great showing getting into round 2 in their first year!
The minibot is definitely the MVP! The main issue was that there was too much space between the baseplate and the inner shell, so the shell could wobble too much with that clearance. The second fight, since the driving pulley is the highest point in the internals, when the shell rocked in that big hit and kept spinning, the top of the shell knocked into the pulley hard enough to break the shaft going through the right angle gearbox. The gearbox surprisingly held up great!
The solution to that problem is rub blocks along the baseplate for the future, so the shell can't tilt so much. We've also since revised the driving pulley attachment method so that it's not as close to the shell lid.
In the rumble, the issue was from the weapon pulley! The main shaft is a big bolt, locked in place with two nuts. The threading on the bolt was just a little too long, and Cookie spins in the tightening direction. This is great for making sure the weapon pulley doesn't fly off, but the nuts tightened enough in that hit to lock the whole thing up. Everything else was fine after that, so we got a longer bolt for the future and adjusted the spacing to those nuts. There was some smoke in the rumble, but it was from the belts burning up as they tried to spin the locked up weapon pulley.

Thank you for the very detailed and well laid out reply, very much appreciated!
You clearly have much more information than the video, so I'm guessing you have something to do with the bot or have other sources perhaps?
I will be looking out for the upgraded version, seems like most of the issues have been addressed already, so I'm excited to see the results!
@@kholdanstaalstorm6881 I'm the builder, thank you for the kind words! We brought it back to Motorama Robot Conflict this past weekend (with legs!) and it's definitely going the right direction, but lots of problem solving to keep me busy haha
@@lucidahand7975
No wonder you had all the details, dealing with the issues first hand!
Thank you for taking the time to chat with me, I'm very honored and grateful that you did that!
I can only imagine how much you're kept on your toes in that position, not to mention all the possible and impossible things that can happen in a fight or a full series!
I've done some project work and management in a different field, so I know how it can throw you a curve ball from your blind side.
I would love to "pick your brains" with someone on the specifics of robot combat management, but an open UA-cam chat isn't the time or place.
They say "break a leg" when wishing all the best in the theaters, but I haven't learned the equivalent proverb for robot fighting.
The sentiment still stands though, so fingers crossed for you and the team!
@@lucidahand7975 Radial needle bearings and hardened washers will help with that. They're inexpensive at McMaster Carr.
Oh hey, there are still robot fighting things? Nice!
Cookie op be like "I only like being able to hold up on the throttle"
An unique concept indeed, but a lot of work to be done in many aspects of the bot, like balance before spin, speed and maybe a self right mechanism, i am impressed by the damage it deals.
Needs more refining, but I like the concept.
I love ambulatory systems that use stuff like torque, centripetal acceleration or center of gravity shifts to navigate, it's such a tasty challenge.
Didn't loss of controlled locomotion used to be the condition for a loss? Since when did that change? A bot getting to the state this bot starts at used to mean you've lost. If you're weak as a pilot, there's a reason this is teams and not just 1 individual. If you wanna take part in an uncontrolled bot competition, that's a thing, it's just not as dynamic, because the pilots can't change the course of the battle through their skills
IMHO this needs to be built from the ground up, not with spare parts, excited for a v1-v2 of this bot
I love the idea. I'd like to see it not cut up the arena just to get going though. Lumber isn't cheap haha
awesome bot
*big cookie strong big cookie work*
First hit, Thinged a bot. Second hit, TORE A WHEEL OUT.
It seems to get knocked offline by its own power. Hopefully it can be solved
I don't build robots with wheels proceeds to build robot that's giant wheel...😅
for the love of the welding god, grind em out and weld it properly
I've been watching battle bots since I was about 7 ,or so . I been waiting make my own for a long while now , and I've found a hobby shop that sell little battle bots . There about 20- 30 US dollars though ,but there is another hobby shop that some can make there battle bot ,hope one day to make ,or buy my own.
That's how it should be really with robots
Make it a conversation between the driver and bot
What can and cannot the driver do? Have the robot be built to take advantage of the driver's skills and navigate around their weaknesses
Of course this is just saying and not doing but the concept is excellent in of itself
Damn even depth charge has more control
I'VE FOUND MY FAVORITE IN MY FIRST VIDEO
The blendo flashbacks are real.
big cookie destoryed the whole floor oh wow
Fun robot but it keeps on shutting off.
Mo' Wheels, Mo' Problems.
Dumb girl "logic".
MAAD RESPECT for her concept… That’s what the ring needs
Since I'm new to this why does big cookie get a mini bot to help it?
Unconventional mobility gets advantages
It's 1 big wheel though
Aka i power on the robot 😂
Wheels? Who likes wheels?
You could make it walk in any direction with an Arduino and gyro board
tapped out at waffles
lol its a beyblade
I like the concept, but the lack of steerabiility ruins it for me. You can just adhoc a gyroscopic steering build that depends on vibration to get moving. You have to do a lot of math and program a conteoller to pulse slowdowns and speedup to steer this thing. There is no way a human can manually do this.
Battle bots need to start the first round with a control testing course. To disqualify robots that can't be controlled with intention.
At one point, a loss was declared once that control was lost, so under the original rules of these guys at least, this bot started the round in a loss state already, meaning they'd need to somehow end the fight before the 10 second countdown that started immediately was up.
and I am with you on this, this kind of bot is what you're looking for in unmanned bot competitions, it's antithetical to this style of matches intentionally. The main reason for manned bot competitions is the dynamics that comes from the pilot being able to shift the battle's direction with their skills, but that's not present with this bot, because the pilot isn't a good pilot and because they're also one of the builders, they just deleted the chance to offload that role to someone who can pilot, as most of these teams do, because that's part of why this is a team competition
Big cookie will devour your ankles.
She should get a 1 button remote.
Big Cookie is monster! :D
Does she have any control over it at all?
Some, but it’s a new robot and it takes time to get everything dialled in. It’ll be much better each time they run it. When they do it’ll be a beast.
She explains the control method at 7:33
@@TeamSmallRobotsshe explains how it moves and how she has very limited control intentionally, because she sucks at piloting, so she just sets the bot up to not need piloting and instead just let her button mash essentially in hopes it works out fine, which means it is already in the 10 second countdown to loss immediately upon starting the match and should be losing every match as a result, if they didn't decide to make an exception and allow an unmanned bot in this manned bot competition, when her skills would fit perfectly in an unmanned competition, though those don't get as much attention, because those bots function like hers, not able to be substantially influenced by a human's moment to moment judgments during the battle, resulting in less dynamic and interesting fights
I am kinda new to rules, isn't is illegal to have two robots against one?
Depends on the match, different competitions have different rules, but in a lot of these, there's generally a house bot that exists primarily to make things happen when the fight just goes stagnant without a clear victor
In this there was an "anything goes" match, where they did explicitly bring up the fact the minibots were allowed in that case
I think the idea is to actualy be able to control your robot. Just putting a motorized spinner in the arena and seeing if it hits something isn't a robot.
It is controlled with torque steering. This was its first outing so we're still getting its legs under it ;D Especially in the smaller versions, directional control is apparent. Some structural changes will allow it to really show what it can do in a future event :)
@@lucidahand7975 how about making part of the baseplate able to tilt to change the pressure on the bristles attached to the tilting section?
@@greggv8 We tried servo-powered legs at Moto and they're promising! The biggest advantage to that is angling the shell to get more bite. The torque steering works great when the weapon is a tad more balanced than it was at this event.
tbf none of these things are robots, just RC cars
I don't think this honors the nature of the competition being a sport, being able to drive and control your robot is as much a part of competing as making the robot, her robot is so slow and uncontrollable that she stands no reasonable chance of catching her opponent, instead the onus is entirely on her opponent to either drive into her bot or literally sit there motionless for a minute while her robot slowly approaches. If not disqualified she should be cheesed out of any chance of winning by opponents using light flails, these flails will have no chance of doing any actual damage but a hit is still a hit and if they hit her bot without ever letting her retaliate (because again the onus is on them to let her hit them) then she loses by default, as she should.
A well operated and very strong spike hammer through the openings in the top of the shell would have Big Cookie blend itself to death. It'd be a hard jolt to the attacking bot but highly destructive to Big Cookie.
I'd be leaning towards a DQ based on how much damage it does to the arena before it even gets to attacking or getting hit.
Yeah, joke bots
Eh I’m all for being creative, but this is not for me. Possibly my least favorite bot I’ve ever seen. No offense to the creator.
idk about this one
