. He created his own version of the device with several improvements, adding adjustable lenses and a moveable carriage system that would allow the operator to change the size of the projected image. He also made it possible to project several different images at once using more than one painted glass slider. The resultant display had a very ghostly effect especially when in a smoky atmosphere. Through this the operator had the ability to manipulate images projected from an unseen location. In 1799, after further refining the system, he received a patent for his "magic lantern on wheels", naming it the Fantoscope.
Shows
Robert developed a phantasmagoria show based around his projection system and the use of other effects and techniques. Robert scripted scenes that involved actors and

Robert appeared at the Pavillon de l'Echiquier on 23 January 1798 and performed his first show. His charisma and the never-before-seen visual effects left the audience convinced that they had seen real ghosts, with many left terrified by the performance.

It was during this trip to Bordeaux that Robert first experience balloon flight as a passenger - an experience that would have a massive influence on his life.

Nevertheless, close examination of the results shows, that many of them contradict with laws of physics, which were already known at the time of the flights. Prof. L.W. Gilbert discussed the results published by Robert in his
