That's beautiful! Really elegant. There's obviously a lot of careful thought gone into it - but I'm a little anxious about the durability of the carbon-fibre framing for a fighting machine. Weight = excellent. Single-hit impact resistance = excellent. Torsional stiffness = excellent. But a circular saw-style vertical spinner would have quite a lot to 'nibble' on. Rodents are famously able to chew through just about anything non-ferrous...
This new version looks amazing! It seems like you have thought of everything! I am interested to see what it's flaws might be after the compatition, because I can't find any flaws looking at it right now!
I stand by the statement that you know what I meant, and in the course of 17 minutes, I'm bound to make a mistake or two. But thanks for taking the time to point it out ;-)
Man, I am EXCITED to see this thing in action. That's a beefy spinner and an awesome design, and hub motors pretty much never break, unlike belts, which basically guarantee breaking every match for you lol. But really, that is one mean bot.
Wish I had means of building my own idea. What would you think of I triangular frame with circular disc just inside corners of frame. Spun from central motor and wheels like low low man above and below weapon. End of weapon will have weights on disc like SOW. Weights perpendicular to disc so can reach as far vertical as possible. This way can hit from almost any direction, and can do upside down. One colored arrow pointing to front on top and another color arrow on bottom still point to front. Switch reversible on radio? Not sure what size and weight it would be.
Very nice. You could probably tongue and groove your wall section for your top and bottom main body grey parts, but in a ‘castleation’ manner to allow for the symmetrical one part design method. May add a bit of extra strength uniformly around the wall section, rather than your possible peak stress areas around your pins.
I wonder if a thin titanium layer (0.5mm?) laminated onto the CF would help deflect hits. Like some other commenters I'm worried that a hit to the CF will shatter a whole side of the frame. For example rickety cricket hit the previous frame and bent it notably. I'm really curious to see what this frame would do in the same hit. Time will tell. Beautiful work as usual all around.
Do the rules allow a gyroscopic stabilizer? With the horizontal centrifugal force from the weapon, the gyro may be useful in counter-steering the vehicle so that it will respond better to your inputs. The gyros in modern sky and land RCs could be very useful.
So I watched a video about one of your other combat robots Kamikaze and you talked about how that is an ABS frame. Is there a big reason you switched to Nylon-G and Nylon-X? What I mean to ask is were there any huge issues when printing with ABS as opposed to these composites when it comes to the robot being robust "enough" to survive matches?
ABS and PLA just aren't strong enough for combat. Kamikaze was a very early bot, and before nylon-based filaments were very popular. There's a group on facebook just for 3d printing for combat robots, you can join that and learn a lot.
Fun fact, PB V2 was partly the inspiration for Malice. Also, PB can't balance on any part. I guess it could lean against the wall somehow. But it can't balance the way Malice can.
This reminds me of the robot team malice made i think it's called malice? Anyway going to be interesting seeing copperhead fight malice if you do since you have a similar robot to theirs. Goodluck with battlebots
@@RobertCowanDIY thanks would not have found it without your help and I think the spinner is closer to malice but the body of psychotic break v2 is closer to malice
It looks so clean. Wish there was a way to keep the weapons motor wires down without tape ruining the _aesthetic_. Its like a designer fight bot. Like if it wasn't designed for destroying robots it could totally be an industrial design designer bag. Edit: 13:41: He does the thing 😮😊
Awesome! Just a though: Would it be beneficial to have two counter rotating blades right on top of each other to act like sheers? It often seems like the damage of spinners is greatly reduced when the opponent flies away. For example the damage of Scorpios was devastating when it hit copperhead from above, despite it being a relatively small spinner.
This would just guarantee you wouldn't make contact. It would just rub or grind. OR, it would be too slow and there wouldn't be enough kinetic energy to do anything.
I just buy the ones from ServoCity and add my own motors. It takes maybe 15 minutes per, if you fully go through and clean everything up. Of course, machining down the outer gear takes more time, but I have a jig for that.
Yes. It takes ~5 minutes. Taking the bot apart is a great thing to do after every right regardless. You don't know what's shifted or what's on the verge of breaking unless you take it apart. After every fight I change the battery and go through everything to make sure it all still looks good and still works as it should. Then before each match I put it into the arena just for a second and make sure the weapon and drive function. This is why you rarely see me go into a fight with a drive side or weapon not working.
@@RobertCowanDIY Thanks so much for responding. I've had tons of experience in FIRST Robotics, but I'm quite new to battlebots. I'm thinking of building a version of this robot but I want to increase the inertia of the weapon by adding a flywheel that is mechanical linked to the weapon and runs significantly faster than the weapon. Then you could have a smaller spinning mass (making you more maneuverable) and more inertia at the same time. Have you ever done something similar and if so what are the drawbacks besides the usually complexity and reliability issues.
@@RobertCowanDIY That is what seems to be the best in battlebots. But I'm used to building swerve drives and turrets so I'm probably gonna add some cool factor by taking away some reliability.
@@matthewthomas9383 It's always a delicate balance. I could probably just build a wedge with 4 wheel drive and get the same number of wins, but in the end, I want to put some bit of my personality into my bots. The best design choices are where you don't have to make compromises, but those are hard to come by.
@@RobertCowanDIY my institute don't have mini lathe....but will try to work with copper....and I'm a hobbiest not a business man...can do it but it's not my idea and not my cup of tea..
1:48 took my breath away, it looks like a pro-designed CAD model.
it's absolutely beautiful btw
That is a big improvement just by looks alone. I bet that horizontal spinner can take on vertical discs and drums quite well.

With that blade... they’ll be long gone before they get anywhere near the frame!
Beetle weight? Right? Would love to see you over at BuggleBots one year. Very nice build, super tidy!
Outland he is. He’s on the copperhead team and drives sometimes

3:42 - "Nylon G which is glass fiber reinforced carbon fiber" - do you still stand by this statement? 🤔🙃

This robot is a work of art! Do you plan on bringing it to the next Arizona Robotic Combat competition?
Thanks! I won't be attending the next ARC since there's a conflict with filming Battlebots.
@@RobertCowanDIY Ah, I figured. Well I hope to see you again at maybe the fall one! I am getting started on making an Antweight finally.
Nice!
everything you build is incredible! what is the plan with that unbalanced disc you mentioned?
Thanks! I'm not sure, I might to try and balance it.

PB V2 was doing its Malice impression at the beginning lol.

HA! three members on team Malice were at the competition. This is is somewhat similar to Malice, but I think Animus is closer.

@@jevil9117 search the interwebs for 'animus beetlweight'.
@@RobertCowanDIY thanks would not have found it without your help and I think the spinner is closer to malice but the body of psychotic break v2 is closer to malice
Hi Robert, what 3d printer did you use for printing the body?
I have a Prusa Mini and a MK3S that I use for all my prints. Almost everything was printed on the MK3S with a Nozzle X.
She's a beaut.
It looks so clean.
Wish there was a way to keep the weapons motor wires down without tape ruining the _aesthetic_.
Its like a designer fight bot. Like if it wasn't designed for destroying robots it could totally be an industrial design designer bag.
Edit: 13:41: He does the thing 😮😊
I had the same thought. Tape is ugly and not entirely effective. The little clip was a great last minute addition and worked perfectly.
Awesome!

Elegant design! Are you still having to build your own brushless planetary gear motors or are they available already assembled?
I just buy the ones from ServoCity and add my own motors. It takes maybe 15 minutes per, if you fully go through and clean everything up. Of course, machining down the outer gear takes more time, but I have a jig for that.
@@RobertCowanDIY Does the motor pinion fit right on the motor shaft or do you have to machine it to fit before adding the planetary gearbox?
@@machine2747 I have a whole video devoted to the brushless drive, that should answer all your questions.
Murphy's Law tells me that the little cable clip added at the end will somehow be the downfall of the bot
Murphy was wrong. It stayed in place during the whole event (even when bearings exploded!) and worked flawlessly.
So you have to take the whole thing apart to charge the battery?
Yes. It takes ~5 minutes. Taking the bot apart is a great thing to do after every right regardless. You don't know what's shifted or what's on the verge of breaking unless you take it apart. After every fight I change the battery and go through everything to make sure it all still looks good and still works as it should. Then before each match I put it into the arena just for a second and make sure the weapon and drive function. This is why you rarely see me go into a fight with a drive side or weapon not working.
How did you get that texture on the sides of your 3d prints?
Cheesecannon25 that’s just what nylonG and nylonX look like when printed
You're out of paper towels
No I'm not, they're packed for the event. ;-)
Is it just me, or does Psychotic Break V2 looks a lot like Malice from Battlebots 2020?
Not just you, some of Malice's design choices were influenced by Psychotic Break.
What is the weapon motor used? Also how big are the wheels
The weapon motor is a unicorn. Check out my video on hub motors, it's kinda custom and also not sold anymore. The wheels are 2.25" I think.

All points into attack I guess.
Actually, the drive turned out to be VERY good this time. I think I figured that out. It's oddly maneuverable.
