7 tips for UNBREAKABLE 3D printed combat robots - EP1

If i could offer just one tip it would be: Leave space for wiring. Always leave space for wiring.

You should definetly do some tips for the electronics of a ant or beetleweight combat robot, showing people the best places to buy esc's and other parts would be great!

check out pctg as main material to robots 😉

Come to NHRL!

Great video and series idea! I feel like I should do something like this for US beetleweights...

unbreakable? hold my beer...

Design for assembly and repair is the place I fall down when building things for my R2-D2. Right now I've got version 2 of a new part printing because version 1 has plenty of room for the assembley screw... but no room for the screw*driver*.

And I've come to realise that threaded inserts only help if you expect to undo the screw a lot. If you're just putting it together once, screwing straight into the plastic works well enough.

Finally, air armour just makes me think of the Battle of Britain. Everyone remembers the Spitfires, but the Hurricanes did yeoman work there - in no small part because they were hard to shoot down. Because they were wooden framed, fabric covered planes which made them a little slower and little less responsive (fabric is less aerodynamic than aluminium) but meant that much of the time, German cannon shells would just punch through without exploding because the fabric wasn't solid enough to detonate the fuse.

Can you recommend some sources on rules, how to build cages, streamed events etc for antweight combat robotics? There is a lot of wonderful, weird stuff posted online and I am really getting confused :P

I love the name, 'dead cat, bounce'

Hello a question, I am working on creating a combat robot and I do not know what material to use for the chassis and other parts of the robot you can only use 3d printing, the robot must have a maximum weight of 3 pounds, what material do you recommend?Thank you

Angus, have you tried Fiberflex CF-TPU for these robots? (yes, carbon fibre tpu, sounds mad, seems to work!) Clough42 just did a video on using it for milling machine way covers and the first thing I thought of when he was talking about it was your combat robots 😁

Great tips for someone looking to get into the sport!

I would design FDM parts in the right orientations, then glue them together. instead of printing in one piece.
3D prints are very orientation sensitive. like any stranded material like wood or sinew.

I wouldn't mind printing one for shits and giggles, but I don't know of a good free model.
Others want money for them, which I'm allergic to!

I like using plastites with undersized holes for my US antweights and beetleweight, woodscrews work well too. On the rare occasion when one does get pulled out, it brings chunks of tpu with it since it holds so well, and it’s a lot lighter than through bolts or standoffs.

This video came out just in time! My 3d printed bot was very much broken

As a repair tech (live audio gear) I cannot tell you how happy I am to hear a design engineer talking about taking "ease of repair" into account. EVERYTHING in a machine is either a consumable, or something that has the potential of failure. You will ALWAYS need to disassemble something, even if it's for lubing/maintenance, so why not take that into consideration during design

Such a cool video!! How do I find my local scene for these? I live in Maryland in USA.

You are moving out?

I always have to learn the same lesson of not looking for reference models for making phone cases. Lol it helps so much!

im watching this even though im not gonna make one of these

Great video as always Angus! I do have some questions for you:

1. Have you used Plastites or wood screws in your prints? Other than the the options you mentioned, those are ones I’ve heard from other builders.

2. Does Australia have Plastic Antweight competitions? To clarify, the type of competition that only allows PLA, PLA+, ABS/ASA, or PETG. If so, I’d love to hear your tips and tricks for those!

3. Any sneak peaks on what future episodes there may be?👀

will threaded inserts still work on US antweights? cause my frame is going to be nylon(idk if cf or gf yet) so i think threaded inserts will work

Thank you for the tips. You are doing a wonderful job. God bless you❤. Please keep on making such informatic video 🙇

Video 6 of asking for dead cat bounce pt 2. (I know you mention him in the video)

Its amazing they are so accessible. My favorites are still razer and hypnodisk tho :)

I was thinking with the amount of force applied in an attack, each pocket of infilled air can act as compressible armor. Three minutes later, you mention this. lol

Guilty multiple times of small to no clearances. Because I intentionally avoid F360 and I use FreeCad, there are cases that I can't (or I do not know how) to do clearances in complex geometries especially when one object is derived by extruding into another object. Then sanding comes into play

Hope you’re doing well man

Happy that this dropped during me and my friends conversation about battle bots…

I recently began working on small robotics systems for my engineering high school engineering teacher to use in his coding class, a lot of your combat robot videos gave me the inspiration to create these robotics systems, thank you!

im so excited!!
im getting a bambulab a1 mini in two weeks!!!

Broken Link is a good kid, but you need to give him some tips on delivery. He's not very enthusiastic.
