TinyLink: Natural Language to MAVLink for PX4

Spotlight
1

Hello PX4 community,

I’ve been working on a project called TinyLink, a lightweight LLM that translates natural-language instructions into MAVLink commands.

Some key highlights:

  • Runs 100% locally. No cloud or API keys needed

  • Works on modest hardware

  • Supports Arm, Disarm, Takeoff, Land, Return to Home, Move (XYZ), and mode switching (e.g., Offboard)

  • Allows non-technical users or operators give natural language commands to control vehicles.

  • It’s not a full chat assistant. It’s just a clean, focused interface for supported commands.

Here’s the Github repo and a screenshot of a demo using PX4 & Gazebo SITL:

I’d appreciate to get your feedback. I’d like some advice on:

  1. Setup for running TinyLink on Raspberry Pi 5 with PX4 SITL/Gazebo on another PC
  2. QGroundControl integration

Thanks!
