They are hexagonal standoffs, 6mm across, 35mm tall, with M3 female threads on both ends. Some are aluminum, others are nylon to save weight. www.digikey.com/en/products/detail/w%C3%BCrth-elektronik/970350366/9488512
What is that little custom washer for? (Does it help ensure that the force is getting divided between the 3 screws?) What is it made out of? And this might be a dumb question - but that TPU ring that is mounted to the top half of the chassis. It's not a bearing or anything, right? It's just there to act as a shock absorber on big hits?
The little custom washer is there to prevent the TPU hub from popping off the motor, which happened in one of my tournaments twice. And yeah, the TPU hub is just a shock absorbing way of mounting the motor to the weapon. The weapon can actually slip and rotate a little on the TPU hub, so the motor doesn't experience all that shock when the weapon hits something.
Hello, incredible video!!!, question, what is the electronics that you put on it? I would like to know the controller of the two motors to connect them to the receiver
I mostly use the same electronics in the Fingertech Viper kit. Andrea from team Witch Doctor explains motors and speed controllers here: ruclips.net/video/UYv1pQnQvP4/видео.htmlsi=5ZT38DJGQRID0oqt
@@alexsalchemy Thank you very much, I really liked the electronics you are using and I wanted to implement it in my battle robot to get more space, your battle videos are incredible!!!
Yeah, just enough! Each nylon spacer weighs 1.1 grams, while each aluminum spacer weighs 2.7 grams, so replacing five of my aluminum spacers with nylon saves about 8 grams total, which just barely allows me to use some of my attachments.
@@alexsalchemy Its all about the small grams! hehe. But in one video you said that your side and back armor only weighs 33 grams. Can it really be that light? Looks like its a more rigid plastic behind and TPU in front of it
It is indeed just 33 grams. Each side piece is 3D printed TPU with just 5% infill. It's mostly "air armor" putting a lot of distance between the inside of my robot in the outside, which an opponent's weapon needs to reach through in order to really damage me.
@@alexsalchemy Ah smart! I was first thinking of having a more rigid plastic, lite PC at the back and TPU in front of it, glued in place, but it gets very heavy quickly. Even the back armor only in TPU with 5% infill is 17g. Need to try to make it lighter
@@alexsalchemy What is it that you have wrapped your TPU wheels with, on the outer part of it? Doesn't look like the same material as the rest of the wheel. Maybe something more grippy?
I get my top and bottom armor (carbon fiber plates, 0.060" thick, or roughly 1.5mm) from SendCutSend.com, although CNCMadness.com seems to have better prices.
One of the reasons I chose a horizontal spinner was because it allowed me to turn quickly, unlike a vertical spinner which fights gyroscopic forces. So that's my two cents!
Realy cool 😊
Great design! What are those double sided nuts you used to connect the chassis together?
They are called standoffs.
I’m using the same exact motors for my own robot, what gear ratio did you use
How heavy of a weapon are you running?
About 56 grams, on an 1800 KV motor at 3S voltage.
Absolutely love your vids :)
What size standoffs are those, and do you have a link to them?

Thank you so much. Cheesecake and Dulce De Lucha are my favorite 1lb robots

I see you are using nylon and aluminum spacers. Is there so much weight different between them? I would think they are both around 1g each.

So thats how o bake cheesecake hmm yes
how thick is your weapon? Is it Steel?
It's about 1/8 or 3mm thick, and I'm using AR500 steel.

One day i want to make a bot that is fast and aggresive

Bro he is kind simple 😅😅😅
