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.

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.

@wristofkings Год назад

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.

why did the vert get an unstick in the first fight? Big cookie worked to deliberately stack them, isnt that a legitimate strategy?

@lukeb0t Год назад

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.

@04liverydesign7 Год назад

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.

@kholdanstaalstorm6881 Год назад

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!

@lucidahand7975 Год назад

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.

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 RU-vid 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!

@arielr9614 Год назад

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.

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 :)

@@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.

@cognisant307 Год назад

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.

@greggv8 Год назад

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.
