Challenges in Creating an Introductory Sequence in Robotics

Robotics combines multiple disciplines, and students coming into a graduate degree in robotics can have vastly different skill sets and expectations. How do you design an introductory sequence that fills in gaps in skill sets? What are the gaps? What should all robotics people "know"? This is partly an analysis of our existing intro sequence (what works, what doesn't) and partly needs-finding for what should be covered in an intro sequence.
