Petoi Quaddle – A mini robot dog for physical AI experimentation (Crowdfunding)

The robot is powered by an ESP32-S3 motion core for servo control and wireless connectivity, and an optional ESP32-S3 AI core to enable voice commands and Smart Home control. The robot can walk, strafe, spin, talk back, and react to the user's touch.

The useful part

The robot is powered by an ESP32-S3 motion core for servo control and wireless connectivity, and an optional ESP32-S3 AI core to enable voice commands and Smart Home control. The robot can walk, strafe, spin, talk back, and react to the user's touch. A Raspberry Pi Zero can also be mounted on the top in place of the ESP32-S3-based AI core.

How it works

  • Three models are available depending on the user's requirements:
  • Petoi Quaddle runs OpenCat open-source firmware (Arduino) already used in the earlier Petoi Bittle robot dog, first introduced in 2020.
  • The robot can be programmed in a visual programming IDE with drag-and-drop [...]

Details worth keeping

If you are not into ducks, but still would like to play around with physical AI, the Petoi Quaddle is a mini robot dog equipped with 4 servos controlling its legs and is designed to help people learn robotics, coding, AI, and 3D printing.
