What it can do

Written by Robotheca from the project's documents.

Serves as a 2.5-inch freestyle quad frame built around the HDZero AIO15 flight controller and Lux camera.
Star-shaped dual-arm frame designed for wind resilience and crash survivability.
Camera mount designed for HDZero Lux at 25 or 35 degrees, compatible with Kayoumini mounts.
Available as 3D printable (PETG-CF, TPU parts) and carbon fiber cut files in STL and CAD formats.

This repository has no parts list Robotheca can read yet.

Notes written by Robotheca from the project's documents.

The HDZero AIO15 is mounted in a frame cutout that keeps its ports accessible.
The camera mount holds the Lux camera on the front of the frame.
The battery lead exits through a cutout at the front of the top plate.
Wires are routed through the space left by 8-12mm standoffs between the slam deck and the frame.

Incomplete documentation

How complete the published files are for rebuilding this robot, measured by Robotheca at commit f3103fe. It isn't a rating of the robot.

3D and CAD files20/20
20 printable parts (STL, 3MF), 26 CAD source files.
Robot description0/15
No URDF.
Add a URDF: the robot can then be seen in 3D and tried in the browser.
Parts list0/20
No parts list in the repository or linked.
Most points to gain: Link to your parts list, or add it to the repository (a CSV or a Markdown table) with quantities, prices and where to buy each part.
Software5/15
Instructions to install or run it.
Link to your code, or add it to this repository. Say which software framework it uses (ROS 2, LeRobot, Arduino…).
Documentation10/15
README of 8,632 characters with 18 pictures; 0 build steps.
Split the build into at least 3 steps.
Simulation0/5
No simulation files.
Add a simulation model (MuJoCo, Gazebo, Webots or Isaac).
Licenses10/10
Hardware: CC-BY-4.0; software: CC-BY-4.0.

Written by Robotheca from the project's documents.

Betaflight is used as the flight controller firmware; the document says its default settings were fairly decent.
Tuning is done with PID profile adjustments checked using PIDToolbox.
Filter settings are adjusted in Betaflight, including removing the first lowpass filter and tightening notch filters.

Robotheca doesn't review code. Read it before running it.

Every file of the project: code, CAD, electronics, guides, at commit f3103fe.
