For the "International ROBOT MAK3R's Day" 2015 in Athens, Greece, I created a puppet on strings controlled by a MINDSTORMS EV3 robot player. It greets the attendees in English and Greek using a Computer-generated voice.
Note that due to missing or non-working functionality in LDD, in the building instructions I was unable to

adjust the upper vertical knob wheels correctly that move the arms. You need to push them more to the inside so they fit to the horizontal knob wheels on the frame and insert two bushes to fix them on the axle, one on each side of the frame.
