I did a basic project and I don't see how you can do robotics without analog systems unless you don't intend to build custom actuators and just buy very expensive off the shelf parts. The digital portion is absolutely trivial.
Analog systems and Analog Integrated Circuits, Analog Systems deals with using Analog chips, analog integrated circuits chips deals with designing such chips, a robotics engineers needs the first one not the latter. And the first one requires EE101 knowledge and signals and systems knowledge for filters etc which the OP is already covering in other courses
