Mohammad-Khalifah1/Mars-Rover-With-Kauda-5DOF-Using-ROS ? reverse-engineered prompt

Build me a ROS based Mars rover project that can drive a six wheel rover, steer with four wheels, and control a 5 DOF robotic arm for sample collection.

I want the code and launch setup to let me start the rover in ROS Noetic, send movement commands, and have the motors handled with smooth PID control for speed and direction. Include support for the sensors mentioned in the README, like wheel encoders, ultrasonic, infrared, methane, hydrogen, and ozone sensors, so the rover can detect obstacles and do simple environmental checks.

Make it feel like a real project I can run and extend, with a clean bringup launch file, control scripts, and any nodes needed for base movement and arm control. If anything about the current ROS setup is unclear, look up the latest docs online if you need to and keep it practical.
