Re: Just a test
All their components will have an engineered envelope in which to work, so all they need is the data from the sensors. If that data goes outside the envelope the thing will break.
I could have told them that.
Perhaps their goal was to see how far outside the envelope it can be pushed before the thing broke.
I am fairly certain that it helps to have some idea of how much 'safety margin' you actually have in a design, as you develop it.
