These have not been available for a very long time. A robot broke on my own personal limited edition Avatar. I was able to find new old stock robots then an engineer took on the project for me and made it way better than the way it was built by the manufacturer. They just put chinzy screws to hold the arms together. And most robots broke by now. This was done the way it should have been done from day one with custom steel pins going through the entire length of the robot. It will fit right into your machine complete with the man inside of the robot.
