Not at all! New drive: Mechanical, electrical, programmers. New arm: same crew. Only a few people can work on it, maybe, but that doesn't mean that other should be excluded. The only time that only one subset of the team (programming, electrical, or mechanical) is needed is when only that team is able to work on a project. Other than things like that, at least two subteams will be needed for any given task, say figuring out a new sensor or developing new concepts.
