Some of them are generated using my own C++ programs. For example, the series on Monte Carlo localization (https://commons.wikimedia.org/wiki/Category:Robot_localizati...) is simply too tedious to be created by hand. The C++ program source code generating the nine pictures can be found at https://gist.github.com/dllu/7076603

As for the diagram of the teletherapy capsule (https://en.wikipedia.org/wiki/File:Teletherapy_Capsule_3.svg), I wrote out the SVG file by hand in a text editor. Extreme boredom sometimes makes one do that kind of thing.
