I would like to work in the robotics industry, and I am wondering which is route is better. Should I do mechanical or computer engineering?
You can typically get there via either department. It depends on the college. Look at each of the colleges you are interested in and see what their department description and course offerings tell you.
Robotics is truly interdisciplinary. You can major in either, depending on which area of robotics you are more interested in specializing in.
