My wife and I made a robot for our wedding to be the "flower girl" and "ring bearer". In the months leading up to the wedding, we realized we hadn't asked any of the nieces or nephews and that we wanted to add something unique to our wedding. She's a mechanical engineer and I'm a software engineer with electronics experience, so we threw something together. My only regret is that we didn't get the robot on camera during the wedding because it worked so great!
