467 stars on GitHub.
The Modular Bipedal Robot is an open-source 3D-printable companion robot from MakerForge Tech / Aaron Mason, built around a Raspberry Pi + Arduino split. The repo includes the full STL set for the v2 body, head, neck, and legs, plus a modular Python/C++ software framework with drop-in modules for vision, speech, motion detection, GPT chat, NeoPixel LEDs, RTL-SDR, and more. Source: https://github.com/makerforgetech/modular-biped
Architecture:
- Raspberry Pi (Pi 4 or Pi 5) handles vision, speech, and orchestration
- Arduino handles real-time servo control via serial
- Custom PCBs for power and IO
- IMX500 AI camera module supported
Software modules (drop-in):
- Animation, Tracking, Vision (face/object), TTS / Braillespeak
- ChatGPT / Translator (LLM-driven interaction)
- Servos, PiServo, Neopixel, Buzzer, Motion detection
- Serial bus, RTL-SDR radio, Viam integration
