Since you're fascinated with both, why not try Robotics Engineering. WPI is the only college in the world that offers it, and I am currently enrolled and loving it.

Also, WPI is very involved in FIRST Robotics. They sponsor a team (190) that is built on campus with students from Massachusetts Academy of Math and Science.
They also offer two full-ride scholarships for people involved in FIRST.
