Robot Class

I am in the process of submitting a course proposal for an adult evening education program that would introduce people to robotics. One of the entries that I must fill in deals with expected material costs. I would appreciate feedback on what would be appropiate expenses and whether the school should include the costs as part of the registration or if the student should buy the components as needed. I am in favor of having an option not to build.

On a similar note, would it be better to first offer a course in "C" programming geared to a possible robotics controller board?
