Build Your Own TARS
The open-source guide to building a walking, talking replica of the TARS robot from Christopher Nolan's Interstellar.
What is TARS WIZARD?
TARS WIZARD is a complete, open-source project that gives you everything you need to build your own TARS robot. From 3D-printable parts and wiring diagrams to the Python software that runs on a Raspberry Pi — it's all here, all free, all open source.
What Can TARS Do?
Walks
Servo-driven walking gait with coordinated torso and arm movement. Just like in the movie.
Talks with AI
Powered by OpenAI with the signature sarcastic TARS personality. Adjustable humor and honesty levels.
Voice Commands
Speech recognition lets you talk to TARS. Ask about the weather, give movement commands, or just chat.
Multi-Language
TARS speaks English, Spanish, French, German, Italian, Portuguese, and Japanese.
Controller Support
Connect a gamepad via Bluetooth for manual movement control. 8BitDo controllers recommended.
Two Modes
Desktop GUI mode with a Tkinter terminal, or lightweight headless mode for standalone Pi deployments.
What You'll Need
Everything is available on Amazon and AliExpress. Estimated total: ~$200-280 (excluding 3D printer).
Raspberry Pi 5
LD-3015MG Servos (x3)
PCA9685 Servo Driver
LiPo Battery 11.1V
Mini USB Microphone
Bluetooth Speaker
8BitDo Controller
3D Printer
Get Started
Download the 36 STL files and 3D print all the chassis and leg parts. PLA or PETG, 0.2mm layer height.
Wire
Follow the wiring guide to connect servos, PCA9685 driver, power system, and peripherals to the Pi.
Code
Clone the repo, install dependencies, add your API keys, and run TARS. Full setup guides included.
If TARS WIZARD helped you build something cool, consider buying me a coffee.
