Build guide

The creator's guide is written in Chinese. It has no license, so all rights stay with the creator: Robotheca doesn't show it here or translate it, and gives its own notes about the robot instead.

Incomplete documentation

How complete the published files are for rebuilding this robot, measured by Robotheca at commit 8dd0d90. 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 50 characters with 4 pictures; 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.
Simulation0/5
No simulation files.
Add a simulation model (MuJoCo, Gazebo, Webots or Isaac).
Licenses0/10
Hardware: no license; software: no license.
Add a license for the hardware (e.g. CERN-OHL-S-2.0 or CC-BY-SA-4.0). Add a license for the software (e.g. MIT or Apache-2.0).
