What it can do

Written by Robotheca from the project's documents.

Two-wheel differential drive small mobile platform built around a Jetson Nano.
Wheels are the same specification as the Raspberry Pi Mouse, with 48mm wheel diameter and 92.5mm tread.
Two cameras mounted 55mm apart, supporting stereo-style vision.
Optional multi-LiDAR mount is available as an add-on part.

This repository has no parts list Robotheca can read yet.

Notes written by Robotheca from the project's documents.

NVIDIA Jetson Nano board as the main computer.
Two 4-phase stepping motors (0.9 degree basic step angle) driving the wheels.
Two IMX219 8MP camera modules (SainSmart, 160 degree field of view).
Custom baseboard, with circuit diagrams published in two revisions (RT-JNM-202003 and RT-JNM-202103).

Circuit diagrams for the baseboard are provided as PDF files, one per board revision.
The board revision can be identified from the silkscreen printed under the Jetson Nano's micro USB connector.
The repository documents do not describe detailed pin or bus connections beyond what the circuit diagrams contain.

Incomplete documentation

How complete the published files are for rebuilding this robot, measured by Robotheca at commit 89584e0. It isn't a rating of the robot.

3D and CAD files20/20
1 printable part (STL, 3MF), 1 CAD source file.
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…).
Documentation0/15
README of 1,140 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).
Licenses10/10
Hardware: Apache-2.0; software: Apache-2.0.
