In the year 2018 the Roomba vacuum cleaning robots became really cheap (at least the "simple" robots without WiFi or camera). Soon after buying one, I found out that the robot has an interface to the outside world (see https://www.irobotweb.com/-/media/MainSite/Files/About/STEM/Create/2018-07-19_iRobot_Roomba_600_Open_Interface_Spec.pdf).

I decided to add WiFi to the Roomba, so it can be controlled by a mobile app. Note: There are a lot of similar projects on the web. So the documentation is sparse and primarily for myself.
