Power module bots started in 2014. Iorwerth was the first of the power modules bots. The first batch of modules came from TV equipment that was salvaged from a failed Spanish TV station in Davenport, IA.
Iorworth was also the first Lee Bots, in 2014, to use Transistors for eyes. These transistor eyes became a very popular look for the bots. Letting the bots show more emotions with a turn of the transistor you can make a bot go from happy to sad.
