Wouldn't you love to have a cute and fun companion on your desk that actually works like a real robot vacuum?

Meet ROBOTOP!

Designed to clean up eraser dust, biscuit crumbs, and everyday debris from your workspace, this tiny assistant sucks everything into its adorable slide-out rear dustbin using a custom-designed vacuum system. Thanks to its smart cliff sensors, it cleans your desk tirelessly without ever taking a dive off the edge. It’s a sleek, functional, and fully 3D-printable solution that is both a joy to watch and incredibly useful!

✨ Why You'll Love ROBOTOP
A True Vacuum System: It doesn't just sweep; it sucks! Equipped with a custom 3D-printable impeller that mounts onto a standard mini DC motor, it draws debris directly from the bottom slot straight into the dustbin.
Smart Edge Detection: Bottom-mounted cliff sensors (QRD1114) ensure ROBOTOP knows the limits of your desk.
Two "Faces" (Sensor Options): Choose your aesthetic! The files include two bumper versions: one for the classic HC-SR04 Ultrasonic Sensor (giving it adorable "Wall-E" style eyes) and one for the high-precision VL6180X ToF Laser Sensor for a sleeker, modern look.
Pro-Level TPU Tires: To handle smooth desk surfaces flawlessly, the wheels feature a two-part design. Print the rigid inner rims in PLA/PETG and slip on the flexible TPU outer tires for ultimate grip.

🧠 Choose Your Brain (3 Firmware Options)
Powered by an ESP32-S3 SuperMini, I’ve prepared 3 different Arduino .ino firmware versions on my GitHub depending on your needs:

Wi-Fi Mode: Connects to your home network. Offers a web interface for live sensor data and manual control.
AP Mode: Creates its own Wi-Fi network so you can connect and control it anywhere.
Plug & Play (Autonomous): The purest form. Just flip the switch and let it autonomously clean your desk.
📦 The 3D Print Files (Plates)
I have uploaded two different chassis setups so you can print what fits your inventory:

Plate 1: The standard version (Designed for the ToF Laser sensor and 2-part TPU tires).
Plate 2: The sleek upper body without the HC-SR04 eye cutouts, plus a 1-part wheel design that can be printed entirely in PLA/PETG (for those who don't have TPU filament).
Recommended Settings: PLA/PETG for the body and impeller. 20% Gyroid infill. Use tree supports for sensor cutouts and the impeller overhangs. 0.20mm layer height.

🔌 Wiring Quick Reference
Right Motor: PWMA ➔ Pin 4, AIN1 ➔ Pin 5, AIN2 ➔ Pin 6
Left Motor: PWMB ➔ Pin 9, BIN1 ➔ Pin 7, BIN2 ➔ Pin 8
Cliff Sensors: Left ➔ Pin 2, Right ➔ Pin 1 (Using Hardware Interrupts)
Laser Sensor: SDA ➔ Pin 12, SCL ➔ Pin 13
Vacuum Motor Signal: Pin 11
Crucial Note: Ensure EVERY component shares a Common Ground (GND).
🚀 Current State & Future Roadmap (A note from the creator)
ROBOTOP is still in active development. I will be honest: packing all these components and cables into such a tiny space turned into a bit of a "wire spaghetti"! I decided to release it now because the first prototypes are working beautifully, and I want the community to enjoy it. My ultimate goal—when I find the time—is to design a custom PCB to completely eliminate the wiring mess and turn ROBOTOP into a highly professional, easy-to-assemble kit. Until then, grab your soldering iron, fire up your 3D printer, and happy making! Feel free to fork, remix, and improve it!

Let’s Collaborate! Please feel free to ask any questions you have, or share your advice and suggestions. I would love to hear your feedback and ideas. Let’s develop this project together!
