Combat robot "Cheesecake" assembly and test!
This is the latest version of my antweight combat robot "Cheesecake". The assembly is basically a sandwich of white TPU and ABS between two plates of 1/16" carbon fiber, held together with standoffs and M3 screws.
Upgrades from V2 include:
- Thicker arms holding the weapon motor.
- A custom washer to prevent the weapon from popping off the motor.
- The wheel wells are conjoined in the back for strength.
The drive motors are 33:1 Fingertech SilverSpark motors. The weapon motor is an 1800 KV brushless motor. The battery is a 3S (11.1V) 350 mAh LiPo, giving me a drive speed of 78 inches/second (2 meters per second), a weapon tip speed of 312 miles per hour (140 meters per second), and a kinetic energy of 145 joules. The wheels are 3D printed TPU with rubber band tires and are 3 inches (7.5cm) in diameter.
The white TPU weapon adapter allows the weapon to slip slightly when it hits something, protecting the motor from shock.

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
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: kzread.info/dash/bejne/h42qk9KKnrTcgJc.htmlsi=5ZT38DJGQRID0oqt

How heavy of a weapon are you running?
@alexsalchemy

About 56 grams, on an 1800 KV motor at 3S voltage.
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.

Thank you so much. Cheesecake and Dulce De Lucha are my favorite 1lb robots
What size standoffs are those, and do you have a link to them?

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

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!
So thats how o bake cheesecake hmm yes
Where do you get you top and bottom armor made

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.
how thick is your weapon? Is it Steel?

It's about 1/8 or 3mm thick, and I'm using AR500 steel.
