This system was optimized for only one roomba to be controlled over the network. Later, a new system, dubbed the Multi Roomba Rover system, would be devised to allow for multiple roombas without needing to run a full separate server and website for each individual roomba rover, and reducing component cost per rover.
The Original Roomba Rover was based on a 600 series Roomba platform. It used a Raspberry Pi 3 for hosting the website, processing video, audio, and control I/O. An Arduino was used for communication between the Raspberry Pi and the Roomba, through the roomba's debug port. The camera was a PS3 Eye camera, and the device had an entire small screen display mounted on top.

## Design caveats
+
+
This whole design did have some drawbacks which were later addressed with the introduction of the Multi-Roomba-Rover system.
+
+
### wi-fi issues
+
The pi 3's built in wi-fi wasn't very good, so it would cut out randomly, causing the entire site to be inaccessible briefly, and users would see the reverse proxy site-down message.
+
This issue was addressed in later roombas with better USB wifi adapters and a separate server for the client-facing website, allowing for smoother handling of network interruptions.
