I am trying to remember the name of this movie from the 80s. There is a family who's Dad has died and they really miss him. The kids build a robot cause they are geeks. Then the Dad comes back from heaven and goes into the robot. I do not remember more than that. All I know is that I think it has Dad in the title. Let me know if you think of anything.

And You Thought Your Parents Were Weird (1991) (http://www.imdb.com/title/tt0101343/)

Holy crap thank you! I would never have gotten that.

"The kids build a robot cause they are geeks"

Ha ha, best reason ever!
