Hi,

I've been trying to figure out the tutorials to understand how to code/control the NXT motors individually using the keyboard buttons (i.e. left,right buttons to move motor A and up,down buttons to move motor B) but the tutorials do not seem to explain much and answers are always vague everywhere.

Also I'm very curious as to what message is sent to the NXT brick to make the motors move and how ROS does it.

Would be nice if someone can help.

Thanks, R
