How much does it cost to build a QuackBot?

The standard bill of materials is approximately $68, but it can be optimized down to $52 by using cheaper servo variants and shared 3D printing batches.

What is a QuackBot Duckoid?

It is a mechanical wobbling robot designed for generative music composition and cost-efficient robotics experimentation using an ESP32 microcontroller.

Can I test the robot's movement without hardware?

Yes, the skill includes a detailed MJCF model designed for the MuJoCo physics engine, allowing for simulation and reinforcement learning training.

What is the primary microcontroller used?

The design is built around the ESP32-S3, which handles both the I2S audio synthesis for quacking and the PWM signals for servo movement.

What kind of musical scales does it support?

It generates compositions in non-standard scales including Bohlen-Pierce, Wendy Carlos Alpha/Beta/Gamma, and custom duck-optimized vocalization formants.

About

The QuackBot Duckoid skill is a comprehensive blueprint for creating specialized, low-cost biomimetic robots focused on generative music and chaotic motion. It provides everything from a $68 Bill of Materials (BOM) and 3D printing specs to ESP32-S3 firmware and MJCF simulation models for MuJoCo. By integrating Kuramoto-style coupled oscillators for wobble dynamics and xenharmonic composition engines, this skill allows users to explore complex robotics and non-traditional music theory through an accessible hardware platform.
