You’ll be able to roll it around and stream live FPV video to your phone as you drive it. In this video, I show you exactly how to assemble, wire up, and program the whole thing step-by-step. 👇 All the files - code, schematics, PCB gerbers, and part list are linked below so you can start this project right away. 📁 *Project Files* - (PCB Gerbers, Schematic, and RTR Code)* https://drive.google.com/drive/folders/1kDjNxRPIFhioJZheGN4Ns0RvkldiFyfA?usp=sharing 📐 *3D model/design* of ESP-ROLL’s Frame (STLs): https://cults3d.com/en/3d-model/game/esp-roll-an-fpv-esp32-spherical-robot-rc-ball-bot-3d-design-stl-files 📜 *Up-to-date Code* (GitHub Repo Credits to ‘s60sc’): https://github.com/s60sc/ESP32-CAM_MJPEG2SD 📷 ESP32-CAM Guide Video - In-depth Code Setup Guide: https://youtu.be/k_PJLkfqDuI 🖥️ *Software* - Arduino IDE: https://www.arduino.cc/en/software/ *Parts and Materials:* $13-24 - (x1) XIAO ESP32S3 Sense w/ antenna & heatsink - https://amzn.to/4kkQnsQ / https://www.seeedstudio.com/XIAO-ESP32S3-Sense-p-5639.html?utm_source=youtube&utm_medium=MaxImagination&utm_campaign=ESPRoll $14 - (x2) 400RPM Micro metal geared motor - https://amzn.to/4kkQlRK $0.8 - DRV8833 Dual motor driver - https://amzn.to/4kGBv7J / https://amzn.to/43CUd9z $0.1 - (x1) SI2300 N MOSFET - https://amzn.to/4kYu1NK $0.05 - (x1) Red 0805 SMD LED - https://amzn.to/3SCIfrr $0.03 - Capacitors SMD 0805 - https://amzn.to/3Htm4S5 (x1) 10uF (x1) 2.2uF (x1) 0.01uF $0.15 - Resistors SMD 0805 - https://amzn.to/4kzlPUj (x14) 150Ω (x2) 240Ω (x1) 4.7KΩ (x1) 10KΩ (x2) 47KΩ (x1) 51KΩ $3 - 3.7V 200-450mAh LiPo cell (Battery) - https://amzn.to/3StvYFz $0.3 - 3mm LEDs: Found in kit - https://amzn.to/4mGnfO3 (x14) White (x2) Red $0.7 - (x1) 5V Active Buzzer - https://amzn.to/43mOJAU $0.9 - (x1) SS12F17 Micro Slide switch - https://amzn.to/4jFvYxo $0.12 - JST Battery connector - https://amzn.to/43kd2iO $0.1 - 28AWG Wire (15-20mm L) - https://amzn.to/4ee4RID $2 - (x1) 60+ gram weight - https://amzn.to/43AdJ6s $1.6 - (x1) 100mm Ornament Ball - https://amzn.to/3Ffq9Zy $0.25 - (x5) M3 Threaded Insert - https://amzn.to/3ZqV7EU $0.1 - (x5) M3 Screw (6mm L) - https://amzn.to/45hqSUy $0.2 - (x4) M1.6 Screw (5mm L) - https://amzn.to/3Tr9eX6 $N/A - 1.5mm Steel Wire (2 short pieces) - https://amzn.to/4jO5Dgv $0.05 - Small Zip Ties - https://amzn.to/3FXtmNu $0.4 (~23g) PLA Filament (Grey) - https://amzn.to/4kCETkn $0.2 (~7g) TPU Filament (Black) - https://amzn.to/43YGABL $13.1 - PCBs and Stencil - Order from JLCPCB Total parts Cost: *~$62 USD* (As of June 2025 excluding shipping and 3D model cost).
