Package Description and Purpose

• This package simulates NASA’s CADRE mission, which focuses on mapping the Moon through a trio of autonomous rovers. The simulation is developed using ROS 2 and is part of NASA's lunar exploration initiative for Spring 2026.

• Lunar Landscape Design: Created a realistic lunar environment in Blender based on publicly available NASA Moon images.

• CAD Model Development: Designed the CADRE rover model in SolidWorks and converted it into URDF format for ROS 2 Humble compatibility.

• Simulation & Integration: Integrated the rover with IMU, LRF, and RGB-D sensors for lunar terrain mapping and exploration in Gazebo.

• Teleoperation & Control: Built a Python-based GUI for rover teleoperation, featuring camera visualization and real-time control.

• Cross-Platform Compatibility: Ensured simulation compatibility across WSL and VMware Linux for flexible development.

The README file for the CADRE package offers comprehensive information about the model and Gazebo plugins, as well as step-by-step instructions for building and running the simulation.

@mkhansenbot Thanks for the Information. Could you help me with this. I am new to Docker and I am not sure exactly what should I change?

[mkhansenbot]

The Dockerfile isn't the issue, the build script build.sh couldn't be run. The CI failed with an error: https://github.com/space-ros/demos/actions/runs/10805650694/job/30002455057#step:3:15

./build.sh: Permission denied

My guess is you need to chmod +x ./build.sh to make it executable. Make sure to do the same for run.sh

[Sanjay-j-p]

Hi Sure. I gave the permission, and git pushed it.

[mkhansenbot]

Re-running the build

[Sanjay-j-p]

@mkhansenbot I am sorry for the errors and trouble. This is new to me. I have removed the -f flag in build.

[mkhansenbot]

The build is still failing

[Sanjay-j-p]

Let me try Locally building it and update you on this as soon as I can.

[mkhansenbot]

Re-running CI

[mkhansenbot]

This is still failing, does the Dockerfile build on your system using the build.sh

[Sanjay-j-p]

It's failing for me. I am reinstalling Docker and trying it again. will let you know once it's successful.

[Sanjay-j-p]

@mkhansenbot Hi, sorry for the delayed update. I had to reinstall my WSL and Docker due to some corruption. Now, the Docker should be built.

[Sanjay-j-p]

@mkhansenbot, I hope the build worked fine and had no issues. Please let me know if any more issues in Docker related and I would fix it as soon as possible. Thank you for the patients as Docker is very new to me .

[mkhansenbot]

Yes it seems to have built now
