"Ron" Tajima of Japan has figured out a clever hack for his Wii Fit balance board and Roomba.
He calls his latest creation the "Surfin' ba."
Instead of just, Tajima also demonstrates how he did it. As with his other Roomba hacks, Tajima attaches a serial Bluetooth adapter he developed himself to the Roomba.
This is Tajima's third Roomba hack. His others are a version of a Wiimote-controlled Roomba, and the Pacmba, a Roomba with LED lights.
