First those kooky guys at MAKE figured out how to control robot-vac Roomba with a laptop. But that used an old-fashioned serial cable. Now they've figured out how to run the thing wirelessly with Bluetooth. Using the software from that first Roomba-controlling experiment, they fashioned a Bluetooth RF device out of a few cheap parts. It worked. The grand finale was the blue dental floss box into which they enclosed the small circuit board. The result? A Bluetooth-controllable robot vacuum cleaner. See the whole process and get complete assembly instructions after the jump.
