You can send me a PM with your questions.
I've cleaned out my PM box so that others can do the same, if they wish. I have been a mechanical designer for robotics systems for the last 15 years, while also being a part of PLTW advisory groups since 2000.
This is the time of year when the high school
PLTW courses have their Principles of Engineering class require students to interview engineers. Maybe other engineers can reply to this thread volunteering their services also. It would be cool to have a thread filled with mentors who are available so that the students can pick and choose who to interview.
