integration of embedded system & robot control system engineering

I have some doubts about integration of embedded system & control system engineering. In india at universities we are taught control theory subjects but in industries never applied. May be because of only maintenance work. Thanks in advance.
Well embedded systems & control system engineering is wide used in some fields like Automotive manufacturing, Transportation ( Trains for exemple) we have good examples here in France with companies like Alstom Transport..Thalès ..PSA ( Now Stellantis)

Can you clarify your doubts on this we can debate here ..
