The goal seems to be reasonable and achievable. From his participation in Robotics club, I have to assume he has the aptitude. Great that you are looking at this before you get to high school so that you can pick the right classes.
I think the plan can use some refinement. Course work should be a big part of the plan in High School. Take the highest levels of math available, For science, take Physics and Chemistry. Mechanical Engineering is applied Physics and Chemistry is a requirement. Computer programming at some level is also helpful.
