Speaking as a member of an all-girls team (Team 433), I'm obviously going to say they're a positive thing.
Guys tend to be more controlling than girls. If we had guys on our team I don't think I would ever get to do anything in the way of power tools or heavy lifting.
Because there is a lack of testosterone on our team, the girls get a chance to use the power tools and prove that we can carry the robot too.
Sometimes I even find it hard to wrestle work away from our male mentors (though I don't blame them, it's addictive).
Point being: being female is not a handicap, and having all-girl teams around allows us to enter more easily into a typically male dominated area.
