At what point does it become unacceptable for a mentor to design/build the robot

If the student learns from the mentor who changed their idea, they will remember the reasoning for why it wouldn't work, or why it wouldn't be as effective as this other idea. Then the next year, when it comes time to build another robot, the student will remember the concept he was taught the previous year, and incorporate that into their new design.

I would suggest that instead of "changing", mentors should "challenge". That is, they should ask the students "Why did you do it this way?" and "Have you considered the following items...?" This does not change an idea for someone, it opens that person's eyes to things they may not have considered and allows them to change their idea. It also opens the door for them to say, "I didn't see that, how would you deal with it?" and let mentoring take place. Even more effective, as the students now know some hazards to look for.
