Say hi to Kibo! Kibo is a desktop companion robot that recognizes human emotions and responds through movement, sounds and visual feedback!
This project was created for Horizons | Hack Club!
What is Kibo?
So the primary idea behind Kibo is for it to be a desktop companion that emotionally connects to people (especially teenagers) and keeps a track of their moods and emotions and to sort of create a register of behavioral patterns. It is designed to understand human emotions and respond through sound and visual feedback.
It has a lot of sensors and a custom designed PCB that pieces together Kibo!

How to Build/Run?
Note: At the time of writing, this is the first version/prototype of Kibo. After getting my project reviewed and accepted, I plan on adding much more features and the firmware will change based on those factors!
Please check the BOM before building this project!
Hardware
- Fabricate the PCB using the Gerber files provided.
- Solder the ESP32-WROOM-32 and supporting components onto the PCB.
- Solder the USB-C connector, CP2102N, transistors, resistors, capacitors, and other components according to the PCB schematic.
- Connect Kibo's external electronic components to their designated connections according to the final wiring diagram.
- Mount the PCB and electronics inside the Kibo enclosure.
- Position the speaker flat underneath the top lid, aligned with the integrated speaker grille.
- Route all necessary wires through the enclosure openings and secure the components.
- Close the enclosure and verify that no wires or components interfere with the lid.
Firmware Installation
- Install Arduino IDE
- Install ESP32 board support through the Arduino IDE Board Manager.
- Connect Kibo to your computer using the USB-C port.
- Select the appropriate ESP32 board in Arduino IDE.
- Select the COM port corresponding to Kibo's CP2102N USB interface.
- Open the firmware files.
- Compile the firmware to verify that there are no errors.
- Upload the firmware to the ESP32.
- Open the Serial Monitor at 115200 baud.
- Confirm that Kibo prints its startup information and reports that the system is ready.
Wiring
Connect all the electronic components of Kibo according to the schematic.

cd backend- Create and activate a Python virtual environment.
python -m venv venv- Activate the virtual environment:
- Windows:
venv\Scripts\activate- Linux / macOS:
source venv/bin/activate- Install dependencies.
pip install -r requirements.txt- Start the backend server using the project's configured entry point.
uvicorn app.main:app --reloadFrontend Setup
- Navigate to the frontend directory.
cd frontend- Install dependencies.
npm install- Start the development server.
npm run dev- Open the URL displayed in the terminal.
- Ensure the backend server is running and connected to the database.
- Verify that the Kibo interface loads correctly.
Operation
- Power on Kibo through USB-C.
- Wait for the ESP32 to complete its startup sequence.
- Open the Serial Monitor at 115200 baud.
- Type:
help- Test the available commands:
status
info
version- Test Wi Fi discovery:
wifi scan- Verify that the ESP32 reports a successful connection and provides an IP address.
- Verify communication between the hardware and software components.
- Voila! Your very own version of the Kibo is ready!

Questions
How big is the Kibo V1 PCB?
It measures 58.5 × 55 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Kibo V1 use?
22 parts, built around the ESP32-WROOM-32, TLV75533PDBV and SS8050. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Kibo V1 KiCad files?
From the rawrrudy/kibo repository on GitHub, at the commit this page was made from: the board is hardware/pcb/Kibo V1.kicad_pcb and its schematic hardware/schematic/Kibo V1.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Kibo V1 design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
