Antweight Robot Construction - Shrapnel!
Вставка
- Опубліковано 5 сер 2016
- This is the construction and assembly of my 3D printed Antweight bot, Shrapnel. (150 gram weight class)
Shrapnel is a slow moving spinner robot. He spins a 25 gram stainless steel bar at around 10,000 RPM!
I've put his design up on Thingiverse. Check it out for more details on how to assemble your own Shrapnel!

From the 3D printer : Shrapnel - Spinnaaaahh!!
Greetings From Greece nice project it looks awesome.
Thanks for the reply...think I might bolt disc on direct for my first attempt will be much easier I think, many thanks
Ooh, this looks super-interesting! Currently all I've got is a zero-budget abomination made out of small remote control car bits, a can and a homemade vertical disc. I'll be looking to nab a use of the 3D printer in college for sure. Thanks for posting the info!
Thanks! Glad you like the video
Nice bot man. How do you attach wheels to 3mm shaft on micromotor, Allen screw?
The wheels I use are simply a press fit, which lasts for ages. I find that the wheel and tread get worn out and damaged long before it becomes loose on the shaft.
Hello again. What fill settings are you using? Rectilinear or Hexagonal?
Hey! I use 20% hexagonal fill. Doesn't really show up well in the video unfortunately.
How big and how heavy is the lipo battery your using because the smallest one I can find in 1in,2in,5in
This is the exact battery I use in all of my Antweight bots. It looks like they aren't in stock right now but you should be able to get an idea of the weight and dimensions from this listing at least.

Ik was building this bot but my Weight is to Heights! What van i chance
FRAME: 40G
BATTERIJ: 18G 2s 450 mah
motor: 18 g
esc: 2x12 24G
esc: 9G
v tail: 4g
drive motor: 2x10 20g
reciever: 7g
140G Total
Beerveen The battery is bigger than you need. A 180mAh would be enough. You could try a dual esc, one that has mixing built in so you can remove the mixer too. Or use a transmitter that can have the mixing programmed inside. You can also try to get the chassis to around 30grams, that was the weight of it when I made this version of Shrapnel. Good luck!
Adelaide Robot Combat thank you
Me again. Guess what. The rear wedge makes it slightly too big for UK fit in cube rules. Is there anyway I can get your earlier version or could you lessen the length of the wedge. Yeah I know im being cheeky asking 😀
I've just uploaded the old Version 8 Shrapnel that didn't have the wedge. If that doesn't work for you, you can always modify it in Sketchup or Tinkercad pretty easily.
You are a star.
hello! Great video. My daughter (9) loves antweight battlebots and wanted to get into making one, like yours. I have no idea what I am doing tho lol. I printed your bot to start with and bought a ton of Brushed and brushless motors with ESCs. I have all the parts but have no idea how to wire them. Any chance you have a diagram or a video going over exactly how you did this. She wants to become an engineer and I want to encourage that but I am a medical professional with no experience in this area besides making one Tesla coil lol
It's great that your daughter and you are keen to get stuck into bot building!
After getting your comment this morning, I attempted to make a document with a series of diagrams and explanations. This very quickly began to turning into something very large and difficult without any descent footage of me building a bot. So instead I've found with a couple of tutorials online that should help you both figure it out. I will do either a detailed tutorial document or video when I'm building my next bot in the near future (I can get good footage and photos as I build it this way).

Although spinner bots are so awesome and I'd love to see another Shrapnel getting around, I would recommend that you build a wedge for your first bot. A wedge will require less parts and you won't have the issues of staying under weight or balancing you weapon, both very annoying things to deal with when making your very first bot.
Have a look at my bot Rollcage, if you haven't already. It is a wedge too and the video does give you a rough idea on what to do when wiring up an Antweight. ua-cam.com/video/YQmMvlJW1rw/v-deo.html
If you do build a Shrapnel, please upload a photo to Shrapnel's Thingiverse page. I'd love to see what you come up with!
If you have any questions, feel free to message me and I'll do my best to help.
FrydDog
Hey, thank you for the advice. We are still tinkering with plans and idea. She just got alot of robot parts and coding tools for Christmas so she is currently working on that. I'll keep you posted!
nice design bro - what plastics did you print in?
Thanks man! I print my bots in ABS.
Hey I know it's been a while since you downloaded this video your robot is so cool I'm trying to build it but some of the links you left are no longer in use wondering how many volts you were thinking on the 50:1 motor
A 2 cell (2S) battery is what you'll use with the motors. A 2S battery is 7.4V.
Thanks so much
Hey I had a few more questions because your list is old a lot of the parts are no longer available so I was wondering how many volts the 260mah battery needs to be ??? And the turnigy brushless ecs is not there if you know of the one it would be so great if you could share the link thanks so much for you awesome help I just love your robot
@@brandoncornelius6541 my last comment says the battery voltage which is 7.4V. The same esc can be found below. The links may be old but all of the required items can be found by simply googling the name of each item.
hobbyking.com/en_us/turnigy-plush-10amp-9gram-speed-controller.html?___store=en_us
And how many volts do the drive motors need to be ???
how much is that
I'm planning on building a battlebot similar design, just wondering how the motor holds up with the weapon mounted directly to it? Or would you advise a pulley system, great robot!
+Gavin Maynard I actually tried a pulley system first and you can find an earlier version of Shrapnel rocking the pulleys in our May Tournament video: ua-cam.com/video/nQ0PnJg2Lqg/v-deo.html
It worked pretty well but I ended up going for my current configuration simply to save on weight. Using the pulley system left me with less than 10g for a weapon bar.
So far the motor is still working and he's competed in our last three tournaments without any serious damage.
Hope this helps!
+FrydDog Can you put by links in the description so we can get the non 3D printed parts? (Can you put one for the wheels also?)
All done mate. Hope it helps
Can you make a more detailed version of this video like you did for Rollcage?
I won't be able to, sorry.
As I've said in other comments, Shrapnel is built and finished and the footage I already have is of a time lapse. A time lapse will not provide any extra detail even if it were slowed down so a more detailed video is not possible. Rollcage's tutorial explains almost all of Shrapnel's components except the weapon. There are countless tutorials online that can explain the components listed in Shrapnel's parts list which should help you build what ever bot you are keen on.
Hello, I want to build my own antweight but i also want to 3d print the chassis. How did you design it to the right shape and also how much experiene do you need? thanks
To design my bot, I used google sketchup. It's a free software that has heaps of tutorials online on how to use it. I had no experience at all before starting to use it. However, it was a lot of trial and error for me to get my bot just right.
I've also been told that programs like 123D and tinkercad are also pretty easy to use for designing bots.
Good luck!
+FrydDog Thankyou Very much. I love your design and was thinking to get into bot building and battling. Thanks!
+FrydDog You earned youself a subscriber! lol
+Miles Pulsford You're welcome and thanks!
Can you put a buy link to the blade?
I'm a little confused, do I have to have that brushless motor control board or can I just hook the motor up to my receiver with throttle.
For each motor you use, you will need a brushed or brushless electronic speed control (ESC). The ESC gets power from your battery and connects to your reciever for it's control.
Thank you. and I looked up some stuff about it. I'm building a battle bot and the motor is for the spinning blade.
Do you use a speed controller for the weapon motor?
Angelo Sincioco Yep, a 10A turnigy brushless electronic speed control (BESC). You can find plenty to pick from at hobbyking.com
Hey there! sorry in advance if stuff has already been answered.
1) I've been a huge fan of robot wars and I seen this as a possible hobby and completely have no idea what I need or anything. (apart from parts and all)
2) does the wiring need soldering or does it connect with clips ect. (I'm not worried about weight as my first wont probably fit the weight so I can get a basic grip)
3) I don't have a 3D printer. do you suggest I look online for places that can offer it or I get some materials and hand make body's with superglue.
4) what will I need to learn to create further bots?
5) can you suggest a good remote with receiver? I've been told to get a decent one.
6) does parts get superglued onto the body and can they be reused ?
again sorry if they've already been answered! thanks dude
Please read through the comments in this video and in my other videos for the answers you're after. I've already referred to a few handy websites for wiring up r/c hobby parts.
Also have a look at a starter guide that I've written up for our group which lists some suggested parts to get you started. For your first bot, cheaper is better as it may not last long in a match.
Here's a link for my guide.

Thanks for watching, hope this helps.
FrydDog thanks for the reply, thanks for the help
Can you pls make a full tutorial for this or another Battlebot? Thx
Hex UFox Inc Hey! I've already addressed this in other comments and I won't be doing a tutorial video for this bot. There is a link for it on thingiverse and I provide instructions there. As far as other bots, I'm not in any position to do a detailed tutorial anytime soon. These videos take a lot out of my time, let alone a long detailed tutorial video.
Fortunately, my bots and most others use basic hobby r/c components. Once you've bought the parts listed in my videos, you can find dozens of tutorials online for connecting it all up. Googling 'r/c wiring tutorials' just now gave me several good options which would be perfect for anyone wiring up this stuff for the first time.
Good luck!
Okay, sry i dont have seen that
Do you need to do any soldering for this bot because i am thinking of building one
Yep! In this weight class you'll always need to do some soldering. Connectors and excess wires add a lot of unnecessary weight which you can lose with a bit of soldering.
Thanks
I have downloaded this 👍🏻
Cheers man! Hope you like it
FrydDog printing the base as we speak. Just fits on my printers bed. (Got a problem with the bed so hopefully bit more room soon). Going ok so far. One of my first 3D prints. 👍🏻
What software did you use to design on computer
RoboticCombatUK I use Sketchup. It's nothing fancy but I find it quick and easy to use.
SQUIRTLE NO
im new to arc and having trouble build a lightweight robot and i saw your robot at the makers event at flinders unieversity
bluey drop what troubles are you having?
wheight sorry for not replying didnt check and i dont have a 3d printer
That's cool! Weight can be a real challenge! Fortunately, you don't have to use a 3D printer to get under weight. It just can make things easier sometimes.
In another of my videos and in two other bots, I've used polycarbonate plastic which has worked pretty well. Other people in our group have used chopping board plastic and even drain pipe plastic!
A few suggestions for losing weight once you made your chassis:
- Shorten all of the wires that are on your esc's and mixer.
- Remove connectors and hardwire to your receiver.
- Select a suitable battery that isn't heavier than you need it to be. I'm using a 180mAh on Shrapnel and a 120mAh on another bot, Green Devil which has a servo flipper.
- Remove the case from your receiver.
- Maybe even revisit some of the parts you use. Maybe you can select smaller and lighter versions.
Message me if you have any more issues. Hope this helps!
Thanks alot do you guys do heavy weight battles?
bluey drop Nah not yet. Only antweight right now and we will be starting beetleweight next year. No plans for heavier stuff anytime soon.
How much did this cost total?
I have $235 as my budget to build a similar robot (Jester) only it will use a sawblade instead of a bar as the weapon.
will that be enough money or do i need more?
BattleBotsAndo yeah that will be plenty. The brushed esc's were about $15 off ebay. The brushed motors were $30 from botbitz. The wheels were $9. The brushless motor was $16 and the brushless esc was about $15. The battery was about $5. The transmitter I use was expensive but you can get away with a $30 one from hobbyking. And the bar I got was free from my work, just 3mm stainless steel. The chassis cost little in ABS filament.
So yeah, you should be able to build something under your budget. ($120ish total)
Yay goodie!
And hey i know this probably isnt your call but i think it would be cool for the next ARC tourny to have all the robots in at once.
1. So you know how the trapdoors open? (obviously)
2. Put all the robots in the arena and the last one not to fall into the trapdoor wins!
I know its probably not your call but still fun idea though ;)
BattleBotsAndo We usually have big rumbles like that in our nights. They're good fun. I just don't put the footage up online every time. I think I have a few older videos of some of these rumbles up on this channel.
You said that right as i clicked on one lol
What kind metal did you use for the blade
For that version I went with stainless steel. I've since gone to grade 5 titanium which holds up very well
Oh ok thanks so much I'm actually printing the body right now
what 3d modeling software you use
SwanDiveInc I used sketchup to design my bots. Easy to use and free!
Thanks
big fan of this bot but why don't you just mirror the design on the other side so it will have no weak spots
MaGma RaYz it would have been hard to do that and still achieve a good wedge at the back. Besides, I've since changed to a completely different design. Thanks though!
How much does it weigh?
Jack Freemantle Last weigh in it was at 146 grams. This maybe change slightly when I make a few small changes to accommodate a new weapon bar.
mini tombstone
are you planning on entering the battle bots
RogueXendrome Not any time soon, those bots cost waaaay too much to build for me to afford!
Adelaide Robot Combat got it bro
ware can you got a 3-d printer
What motor does the weapon use?
I use one of these. Nice, cheap and doesn't matter if I wreck one!

+FrydDog how did you make the wheels/ horizontal blade?
TheMutant Creepers The wheels I bought from here: www.robotgear.com.au/Category.aspx/Category/240-Wheels-Pololu
I also spray painted the wheels to suit my bot.
The horizontal blade is made from stainless steel and I got it machined up by some fellas at my work. I was never able to get it balanced enough when I tried to make it myself.
I did have some success making a blade by myself with aluminium. Since the blade was so light because of the aluminium, imbalance didn't matter too much. I ended up going for the stainless steel bar because I wanted some extra weight for my weapon.
Hope this helps.
+FrydDog cool! Also I'm working on a Lego Battle bot
+TheMutant Creepers sounds great, good luck!
I think the weapon is a little underweight
Inhave downloaded the sparc rules i should be ok
How is the robot circuit?
is this a 1 pounder
No sorry, it's a 150g bot
@@AdelaideRobotCombat if i was making a 150g bot with 4 wheels do you recommend a belt system for the wheels?
@@fcksnca depends on if it's gonna have a weapon or not. If it's a wedge bot, I'd suggest go for a four wheel drive so you can put push your opponents. If it's any other type, go with belts coz you're gonna have weight problems otherwise.
@@AdelaideRobotCombat ok thanks yea I'm using a vertical spinner design
What dose ant weight mean anyone?

I think the weapon is a little underweight
A heavier weapon would be nice. But with 95 grams taken up by the electronics, motors, wheels and screws. And 31 grams taken up by a chassis that has to fit all of that in and still be able to take a beating, I'm not left with much. In the end I settled with the 22 gram stainless steel bar you see in the video. It's worked pretty well for me so far. :)
