What it can do

Written by Robotheca from the project's documents.

Moves on wheels using a Raspberry Pi-controlled robot car
Displays status on an OLED screen
Shows information on an e-Paper display
Lights up LEDs for status indication

Bill of materials

This repository has no parts list Robotheca can read yet.

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 0ea20f9. It isn't a rating of the robot.

3D and CAD files20/20
7 printable parts (STL, 3MF), 257 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.
Software10/15
Code in this repository, instructions to install or run it.
Say which software framework it uses (ROS 2, LeRobot, Arduino…).
Documentation0/15
README of 924 characters with 0 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. 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).
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).

How to run it

Written by Robotheca from the project's documents.

Install Raspbian Buster on the Raspberry Pi using Etcher or Win32 Disk Imager
Use the auto_tsinghua_source.sh script to update package sources
Install wiringPi on the Raspberry Pi for GPIO control
Flash firmware to the motor driver board if required
Power on the robot and test motor, OLED, LED, and display functionality

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