Description: This project contains two battle bots that are meant to battle each other. One has a vertical spinner while the other has a horizontal one. The chassis is mostly 3D printed with some electronics for the drive base. Both bots are powered by Raspberry Pi Zero 2 W boards, each running a local server. Users connected to the same Wi-Fi network can control the bots through a web interface using arrow keys for movement and the space bar to activate the weapon.
Motivation for this project: I made this project because I’ve watched the larger bots and it was fun to see stuff being destroyed.
