is robotics a separate course or it was a combination of courses?
Robotics is a interdisciplinary field of CSE , ME and Electronics. Robotics is intended to develop devices that will have a specific skill sets programmed and they can perform with absolute accuracy.
AI enabled robotics is getting a craze now-a-days. The fields application is increasing in Biomedical Engineering also like the development of Robotic Hand for Surgery.
So studying Robotics means you will be reading a course with subparts of many disciplines.
I hope my answer helps. This is a very rough description. Have a great day!
