Swarm has published Langostino, an open-source reference drone that combines a buildable 6-inch quadcopter with an AI flight-control stack. The project exposes the hardware, ROS2 software, model files and safety tooling so developers can assemble the airframe and test autonomous flight on real hardware.

Inside the 131-D observation

Segment height follows the number of dimensions in the policy input.

100 Action history · 25 past actions

16 LiDAR rays · normalized distances

12 State values · position, attitude and motion

3 Goal vector · direction to the goal

Why builders care — and where it stops

Open by design

Hardware guidance, ROS2 nodes, model interfaces, tuning notes and safety logic are exposed for inspection and adaptation.

Not turnkey

Soldering, firmware setup, calibration, manual override and controlled flight testing remain part of the job.
