Hello. There may be some screws or other small parts not here. I didn’t try to spend the time on it. If you expand the parts pictures perhaps you can evaluate. The box is in pretty good condition. Lots of fun and imagination is created by this . Great as an addition or to get started in robotics.  As is , due to unfamiliarity and untested.  The original receipt from 2006 is included , cause I thought it adds to the history. Thank you
