Beginnings -- Leonardo’s Programmable Automaton and Lion -- Leonardo’s Knight -- Leonardo’s Bell Ringer -- Epilogue Leonardo’s Legacy and Impact on Modern Technology.

Leonardo's Lost Robots reinterprets Leonardo da Vinci's mechanical design work, revealing a new level of sophistication not recognized by art historians or engineers. By identifying his major technological projects, the book reinterprets Leonardo's legacy of notes, showing that apparently unconnected fragments from dispersed manuscripts actually comprise cohesive designs for functioning automata. Using the rough sketches scattered throughout almost all of Leonardo's notebooks, the author has reconstructed Leonardo's programmable cart, which was the platform for other automata: a Robot Lion, a Robot Knight, and a hydraulically powered automaton for striking a bell. Through a readable, lively narrative, Mark Rosheim explains how he reconstructed da Vinci's designs. In a foreword the world-renowned Leonardo scholar Carlo Pedretti interprets the significance of these reconstructions for our understanding of Leonardo's oeuvre.
