The last of the robot was finally scavenged for parts & discarded to free up space.  Looking over the intricate mechanical wood work reminded the lion kingdom what a leap it was to go from a pure software programmer with no mechanical engineering or electronic skills to designing that, within a year.  The mechanical linkages moving DVDs around were a cut above the quad copters & rovers that came later because they weren't just static cargo carriers changing position.  They had to grab & replace objects & travel around large areas with mm accuracy.
