0:49 "I competed with crippling depression" Sounds sad lol.
"Robert Cowan" is now a food review channel.
I should review rap snax!
You know, going 2-3 with a bot that is literally just a rectangle with wheels is pretty impressive when you think about it.
I'd love to see a "version 2" on this. Bullying wedges and pushbots with the sheer dowforce of this thing is too fun of an idea to abandon it like that.
6:20 "Somebody break something... And not the arena."
25:01 yes, yes i am...u cant stop me sonnnnn
"Isn't competitive enough" , at the beetle weight level. Looks like we need a featherweight Longer Maaaaaaaaaaaaaan!
I've toyed with the idea.
Are you going to do recaps for each of your battlebot fights after they air?
Your perspective would be interesting
I plan on doing SOMETHING, not sure what yet ;-)
@@RobertCowanDIY I wonder if a live reaction video of you/your team watching the fights on TV would be interesting.
@@mq1506 MAYBE, but I might just want to watch them on my own privately... Sometimes I don't want a camera in my face.
Maybe you could use a small strain wave gear for your drive reduction? The cup in theory be either plastic or metal 3D printed, or even machined out on a pocket NC.
I have avoided using one for some of my designs since I need the gearing to backdrive in case of power loss, so the axles aren't sheared right off, but with a small robot like this it would be perfect.
I would be up for building a demonstrator unit, since this has been on my list of things to do for a while.
huh...never thought of that little problem with magnets for downforce: when you get hit you stay still and GET HIT, almost as bad as being pinned on a wall.
It seems like a fun class would be beetle and ant "sumo" where you don't allow any destructive weapons (spinners, blades, hammers) but allow lifters flippers, pushers and the like in a ring with a simple wall of a certain height around it, the goal being either toss or tip an opponent. It would make a monthly local competition more appealing since you would not be dealing with shredded parts after every match.
How this relates is that your design would be a great contender in that.
Still watching this :)
lol, i love it! Copperhead looks amazing! I'll be rooting for you guys!!
Not putting a drawing or macaroni art on it billboard style was a missed opportunity for a fridge magnet on wheels
Can’t wait for battle bots this year
With magnets there are two forces. One is the downward force you measured. The other force is caused by eddy currents. when a magnet slides on the surface of a conductor it causes heat in the surface and drag. There may also be drag from friction caused by the down force which would be the same as a weight. Try taking your magnet and sliding it on an aluminum plate. you will feel drag. There also will be repulsion pushing the magnet away from the aluminum.
Rest in peace Long Long Maaaaaaan! You will be missed.
Fun design and looking forward to the beetle-weight build.
Was this influenced by Smeeeeee or vice versa by chance?
Rum Ham’s disc sounds like a lawnmower.
Love those fight recaps)))
Paused @8:58, willing to bet that the wheel issue was something stuck. Because we can see the wheel try to move, but can't. If that's not text book stuck, dunno what is. Amazing little robot for something done on the fly.
You're probably right. and thanks!
Could you put some sort of small internal system to raise/lower the magnets internally to adjust their effect on the arena below them? Raise them to move quickly, Lower them to take hits?
Be neat to have disengageable magnets like a Noga dial caliper holder.
I thought of this and played with it a bit. Those magnets tend to be very heavy, and they work best when actually touching the surface, which makes them problematic to use.
I want to see long long man fight again it seems like a cool concept for a “break a weapon” bot... it seems cool to see a powerful bot destroy itself
LMAO! When you bring an axle to a bot fight! 😂
The end cracked me up!
You need wheel skirts to protect the wheels
that would ruin the aesthetic! I just wanted it to be a polished bar of aluminum that drove.
Using magnets like this is it possible to make a powerful hammerbot that doesn't throw itself around so much? Downforce of 6 times the weight seems like a lot.
YES! That would be a great application for the magnets.
Classic BETA ripped up the floor with all the magnets it had XD, it had the same issue as Long long Maaaaan, soo much downforce it lost all ground clearance, but rather than compressing the wheel ( it used solid Alu wheels) it pulled the floor away from it mounts and glued itself to the spot
Wondering about 'Long Long Man' cluster bot in heavyweight... 🤔
Love your videos but why the lack of contrast when you're on camera? Come on. Give that contrast slider a nudge! :-)
NO! Eh, I'm trying some new things out, still haven't settled on a grading I like.
@@RobertCowanDIY Yeah, I hear ya'! I'm trying grading for the first time on the latest video I'm producing. Not as easy as it looks! Still, some contrast would do you good. :-)
I wonder if you could add electromagnets to temporarily cancel the magnetic field of the permanent magnets when you get stuck.
they have dowsides. I've played with them and they're heavy, use a lot of power, and lose pulling force QUICKLY as you move them away from the surface. They need to be touching to work right.
Tiger Claw use electromagnets If i recall correctly, it also had problems with getting stuck due to the system that turns them off breaking
Still, magnets worked great hope we see long man again. If only there was a way to disengage the magnets.
Yeah, I played around with electromagnets, but they have significant drawbacks. They use a LOT of power, are heavy, and need to be touching the metal they're being attracted to for best results. Even 1/16" away, they lose the majority of their pulling force.
yep, still here XD
RIP Long Long MAAAAAAN!
I tried to enter but they did not have anything on the steam fest web site. Could you send me a link for next year's sign up please? BTW I met the builder of tashu at avc last year, I think he goes to the school of mines!
Here's a link to a website for all Colorado events

Hope to see Deathstorm again
LNDS Studios There is a Colorado Combat Robots Facebook group that will help if you want to know what is going on in Colorado.
@@ianmcmahon8589 ok, sweet! I'll check that out!
Please do a detailed overview of copperhead
You missed it, it was the last video: ua-cam.com/video/5hLn8-amQ8Q/v-deo.html
Hello sir
I am big fan of your robots and your design strategy.
I have doubt in selection weapon bearing used for 30lb, 60 lb and 120lb category.
Which bearing should i prefer for a drum spinner with efficient performance in each category.
I would appreciate if a short video you could make for selection of bearings according to weapon type and weight category.
Otherwise can i have just short reply for bearing used for drum spinner in each category.
Thank you.
This is a very difficult question to answer. There are many types of bearings and many applications for them. You can always look at books like the Machinery's Handbook, it has a lot of information about what bearings to use.
@@RobertCowanDIY thank you sir for the reply
I got the point you wanted to state
I studied lot of bearing types
Now i am just confused between taper roller bearing and ball bearing..
Which one should be the better one for drum spinner?
Thank you for your guidance.
@@ravirajinamke1363 Very simply, a typical ball bearing only supports a load in one direction. Think of a roller skate bearing (which is a ball bearing). It only supports a load in that direction, which could work for a drum. Tapered roller bearings support a load in axial and radial directions, meaning it could support lateral motion of a drum, as wall as the load around the drum. Does that make sense?
@@RobertCowanDIY yah that helped me a lot..!
Thank you for your guidance.
I see promise in the design, but I'm not an engineer yet so take my word hesitantly.
What if the tires were a few mm's taller and you added felt to the underside for it to more easily slide across floors?
That could work. It would make the magnets less effective, but that's not a bad thing.
@@RobertCowanDIY Well with those laws of physics I understand that perfectly.
But at that weight class of robots, and the strength of those magnets. The down force should still be enough to where they would not be able to do anything to you in theory. And the reduced friction may spin a positive as well.
It could translate it to a stronger ram as well not having to battle with that down force right?
Anyway just an idea. Can't wait to see what happened with your team at BattleBots. You vs lockjaw would have been a pretty sweet fight.
@@RobertCowanDIY just as an added sidenote would it be a better design if it was just a 4 wheeled box with 2 neodinam in it?
@@NeverLucky1765 Well, then that would be a completely different bot. It's like saying "what if you added a weapon and a wedge".
@@RobertCowanDIY that's true and I do get wanting to keep it as is, my comment was more of a well what if we did this sort of idea.
22:40 what if you're only use 1 magnet instead of 2 on this bot?
I use 4, and I COULD cut it down to 2...
Are you not able to "Activate/Deactivate" the Magnets via controller?
they are magnets, not electromagnets. you can't just 'turn off' normal magnets.
OH, I just "assumed" that they where Electromagnets...
My bad!
What weapon motor did you use for anxiety attack?
You should check out my other videos ;-)
Which video?
@@merylh5619 ua-cam.com/video/nq0GfEL_CQE/v-deo.html Just to be safe, you should just watch every video I have, so you don't miss anything ;-)
I just watched the anxiety attack overview video again and if you said the name of the weapon motor I missed it. I have a beetle, I compete at motorama and Franklin Institute in Philly. I have a new idea for a bot and want to use that weapon motor. thanks!
@@merylh5619 Well, all those weapon motors are discontinued unfortunately. You cannot get them anymore, even if you wanted to :-( You'll have to use something else.
Fun Fact: real grapes from japan taste like "artificial grapes" so thats why grape flavor tastes like that. Also, bananas from japan also taste like the artificial banana flavor.
Yeah, I get that... But this just tastes wrong.
Its not long enough
Bruh is that huge 18:18
I really want to see a block of metal, sort of like long long maaan but without visible wheels. With a fighting style sort of like duck.
Maybe some day. This was inspired by Duck!
Hobbyweights are 12 pounds.
AH!
Well now you know.
so like a walking hobbyweight then
I forgot about the walker weight bonus.
add bigger moters and get rid of the magnits.
meh, that's boring! I could keep half the magnets...
