To abate any concerns about the safety of the cutting test I showed: I was wearing safety glasses and the grey 'saw' was a PLA plastic toothless disk, and even shoving my fingers into it didn't break the skin. It was cutting via friction melting the PETG blue blade. Don't test dangerous weapons outside a test box. This was not one of those, but even a metal saw is definitely not finger safe let alone most weapons these robots use!
As a SawBot builder, this is probably one of the, if not THE most creative take on a saw robot I have ever seen. I wish you luck with this project, and I can't wait to see how it does.
I'm not a robot builder (yet, who knows) but I think that a drill instead of a saw may be way more effective. Your attack is much more concentrated and you'll be able to go way deeper into the other robot's internals. Not sure if this will work but I think it's worth considering...
There are many issues with drills. One is that they really suck when you aren't using a really stationary and rigid platform to drill with. Especially when drilling into metal. You need to exert a ton of pressure in one spot, way more than you need with a sawblade. More than the weight of a 3lb robot in fact. And if the other bot moves even a little the drill will slide all over. Another issue is that you need a ton more torque and a lot less speed to drill than yoy need to cut with a saw which means adding a really heavy gearbox. Saws work well because the teeth grab and pull the saw naturally into whatever they are cutting from the moment they make contact whereas a drill needs to get its entire point through before it will grab if at all. Saws will also work at a higher RPM range between 3000-30000, I'm planning for 20000. Saws have been used widely in combat bots and shown to be quite fast and effective. Just watch Sawblaze in Battlebots!
For fighting horizontal spinners I actually plan to replace the entire saw and front forks with a lifting wedge of sorts. Only issue is that puts it under 2lb currently so.... Multibot? 🤣
This is a beautiful Design. The creativity behind it astounds me. I want to get into the beetle weight division soon, but i'm not sure what I want to build. My favorite combat robot design has always been crushers, but I haven't seen any viable crusher beetle weights sadly. I wish you the best of luck with this project!
i wonder how effective a skirt guard would be against this. depending on the angle of contact and armor type it may be quite simiilar to hitting top armor
If it is, having the lincage give the saw a more down then punch motion, instead of a chop may help with that. Though I that may reduce it's force of impact
The saw already does a pretty downward motion at the point when it poked past the forks. I will say having a really solid side armor is a concer, especially if the opponent bot is really narrow and the saw intersects the side as it comes down, but I think i can back up and move forward again with the saw lowered a bit I hope
Are you required to 3d print everything? A dremel size large saw blade or a slot cutter would really rip through plastic and some amount of metal. At least a carbon fiber nylon or metal filled filament would be more abrasive and durable. Has anyone made a drill bot?
No no. These are all printed prototype parts. Like I said I'll be laser cutting parts in metal and possibly machining other metal parts for a final version. I'll be using steel saw blades and Nylon or carbon fiber Nylon printed parts where necessary, and probably a few flexible TPU filament parts as well.
One thing about top and bottom armor thickness is material, some bots could change to an aluminum or titanium top and bottom that is thinner than plastic but much stronger to saws
This is true only if they have weight for a more dense material in a large portion of their bot which is very unlikely to be the case. But that is definitely a thing. Anyone who is using plastic will probably not be able to swap for 9X as dense steel it 3X as dense aluminum.
Try pushing a nail through an aluminum plate by hand and you'll quickly see why that isn't a great idea. Generating tons of force with a tiny robot is hard.
What a clever idea! I look forward to seeing it in action. When I first saw the name "Shrapnel Mine," I took it to mean that the bot rips other bots apart and "mines" shrapnel from them, lol. But the actual historical reference is good too!
Probably, but they will also most likely cost a lot more and be bigger/heavier. This is already the higher power version of the common red 20kg-cm servos. And that's with the price rising from about $17 to $37.
Oh don't worry I did! Its response was 'do you even vape bro?' needless to say 3S is off the table 😂 Thanks to Jeff Bezos' retirement fund for the no questions asked returns.

@@JustCuzRobotics Ok that's clear hahaha. Sawblaze is fantastic, although I would say it's 90% a wedge robot...
@@toonverbruggen7351And Drops a Spinner onto what’s it’s pinned
That was one of the most relevant sponsor-spots i've seen in a youtube video in a while.
Better yet, the customer service rep who gave me the code is on Battlebots team Jackpot! SCS is pretty much the ideal sponsor for this sport.
I really like this design, the retracting weapon and pin+strike gameplan reminds me of Tantrum and that bot performed extremely well!
Tantrum did well you say? Don't remind me...
@@JustCuzRobotics
;P
@@JustCuzRoboticsThat Bot is kinda Clever tho. Retract a spinner for it to reach full speed and lynch the opposing machine with it.
Tbh, this is insane in the brain. I wanna make on of these - out of lego.
Maybe as a different configuration, you could remove the saw and saw motor and replace it with a piercing tooth and add a more powerful servo.

Thank you! I think crushers are very hard but by no means impossible at this scale. Just need a LOT of gearing and a screw driven mechanism.
I've always wondered how to exploit the underside-exposure that a P1/Sewer Snake-style flipper causes. Good luck with the concept!

@@JustCuzRobotics fair point, I’m sure many robots will come up with some special armor eventually, like they do with overhead saws
Neat idea. I'm really interested to see what kind of forks and body you pair with this mechanism.
Me too 😊
My take on this type of bot: Armor and stab with a static spike with no machinery aside from moving it
Try pushing a nail through an aluminum plate by hand and you'll quickly see why that isn't a great idea. Generating tons of force with a tiny robot is hard.
I feel like this is the appropriate direction for saw bots to go
