In this talk, Kevin Edey demonstrates how to build a reusable Elixir SDK for the Waveshare RoArm robot arm and deploy it to run on a Raspberry Pi using Nerves.
Starting with the challenge of replacing an existing Python SDK, Kevin walks through the process of reverse-engineering the robot arm's command protocol using Claude, developing the Elixir library using Circuits.UART for UART communication, and publishing the rowarm library to Hex.pm. You'll learn about the importance of establishing a visual feedback mechanism for rapid iteration, the lessons learned transitioning from web-based development to embedded systems with Nerves, and practical workflows for faster development cycles on embedded hardware.
Key Topics Covered:
Reverse-engineering hardware protocols with AI assistance
Building reusable Elixir libraries for robotics
Using Circuits and UART for serial communication
Publishing libraries to Hex.pm
Developing with Nerves and Raspberry Pi
