4 Wheeled robot with sensor mounted to generate digital twin dataset

I need help (tutorial or mentorship) building a four-wheeled robot in a small house with sensors mounted to generate a.json or.csv file with datasets (trajectories, temperature, humidity, gas concentrations)

Sounds like a cool project. I recommend:

Decide what kind of robot you will need for the job. Since I assume this robot only needs to move around, I recommend a simple differential robot. Something like the TurtleBot3 can do the job. Then, add the sensors you need. If you want to use ROS, then you’d need a way to interact with them as well.

Once you have a base, you can start defining it more. Sounds very open-ended as of now.
