Incomplete documentation

How complete the published files are for rebuilding this robot, measured by Robotheca at commit d8cac34. It isn't a rating of the robot.

3D and CAD files0/20
No printable parts or CAD files.
Most points to gain: Add the parts to print (STL or 3MF files). Add the CAD source (STEP, or the CAD program's own files) so people can change the design.
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.
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.
Software10/15
Code in this repository, instructions to install or run it.
Say which software framework it uses (ROS 2, LeRobot, Arduino…).
Documentation5/15
README of 879 characters with 0 pictures; 4 build steps.
Write a README of at least 1,500 characters: what the robot does and how to build it. Show the robot and its assembly in pictures in the README.
Simulation0/5
No simulation files.
Add a simulation model (MuJoCo, Gazebo, Webots or Isaac).
Licenses10/10
Hardware: GPL-3.0-only; software: GPL-3.0-only.

The code

How to run it

Written by Robotheca from the project's documents.

Connect sensor board to PC via USB to use as audio device
Run SDK demo to test audio playback and recording
Use provided USB communication protocol for voice control

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