Incomplete documentation

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

3D and CAD files20/20
227 printable parts (STL, 3MF), 61 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
Built on arduino. The documents have not been read yet.
Link to your code, or add it to this repository.
Documentation0/15
No README; 0 build steps.
Write a README of at least 1,500 characters: what the robot does and how to build it. Split the build into at least 3 steps. 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: AGPL-3.0-only; software: AGPL-3.0-only.
