I’am the owner of a Roomba 531 for a while. I knew that iRobot
had their serial command specification published on the web. I thought it would be cool to control the Roomba by Wifi with a iphone/ipad or normal computer. Unfortunately there are no Roomba Wifi adapters for sale. So I decided to build one myself
The module supports WPS (Wifi Protected Setup), so this makes it easy to connect. It broadcasts every 7 seconds an UDP message, this makes it possible to detect the Roomba in the network
I implemented a switching power supply on the board, the operating voltage is 4.5V – 30V.
At this moment I can receive all sensor values and control the actuators. I will post a movie of the wireless driving Roomba soon.
