GG Battle Robot
This is my custom Robot Wars inspired battle robot with a servo-driven axe weapon, wireless radio frequency remote control with a custom PCB, LCD display, RGB lights, and audio sound effects. The main microcontrollers are raspberry pi picos and the chassis, axe and remote case will be 3d printed in PLA

:pf: their feedback was:
This is a super cool project! However, we cannot provide funding for filament and you can also get the Raspberry Pi Pico from aliexpress to save costs.

Design re-review submission
I sorted out my components, uploaded all of the cart screenshots to github & updated my BOM with my final amount.
I also designed and finished my PCB for the remote, exported the gerber files & got a quote on JLCBPCB and uploaded the files & cart screenshot
I believe I'm ready for re-submission

Hi, we need cart screenshots from where you're planning to buy your parts. Additionally, you mention "PCB costs" in your BOM but do not have a PCB as far as I can see. Finally, please set your grant amount equal to your final BOM amount, thanks!

Importing components
I imported 3D models of the electronic components into Fusion 360 so I can fully visualise their placements, applied textures to my robot and updated my github

Chassis design
I finished designing my robot chassis for 3D printing - took many iterations. I ended up with a single servo-driven axe weapon that rests on the slanted part of the chassis and swings forwards on command.
I made holes in the base for the speaker audio, small indents for magnets so I can connect the bottom & top halves, and added text to the chassis for some extra personalisation.

Planned out where the components will go in the robot
I did a sketch of the setup for my custom battle robot project with the hardware placement. For example what will go on the breadboard, what battery devices I will need to power my components & what motor drivers I will need for my TT motors
