Where is the code? You can find it in the repo, get familiar with the structure. As you can see in this link, other packages are used by Rosbot 2.0 telop_twist_keyboard: https://github.com/husarion/rosbot_de...

If you look at the source code of teleop_twist_keyboard.py you can see that there is communication through termios, tty. https://github.com/ros-teleop/teleop_...

This is read by a serial communicator in your hardware. Your hardware may need their own programs at the lower level. An example using Dynamixel:

https://github.com/ROBOTIS-GIT/Dynami...

There are different protocols of communication, so you need to understand that as well.

In Rosbot 2.0, you can see more info in your specs how this happens.. https://husarion.com/manuals/rosbot/#...

Thank you for your kind!

But, Even if it runs appropriately. I can't find teleop_twist_keyboard.py in my robot.

I want to know where is the code file in my robot.

And, I'd like to motor torque information for my experiment.

Where can I find the lower-level controller in my robot?

Is it possible to get the input torque information?

Your robot uses teleop_twist_keyboard it’s called by the launch file. I also sent a link of the specs of your robot for the low level hardware. Check the last link

From the manual. Software for ROSbot can be divided into 2 parts:

A low-level firmware that works on the real-time controller (CORE2). It can be developed using Visual Studio Code IDE.

OS based on Ubuntu 18.04 or 20.04, which runs on the SBC (ASUS Tinker Board or UpBoard) and contains all components needed to start working with ROS or ROS2 immediately. The microSD card or MMC memory with OS is included with each ROSbot. The OS has been modified to make the file system insensitive to sudden power cuts.

Thank you, sir! I will try to study the lower-level system.
