The guys over at Spark Fun are having a blast creating cool electronics and gadgets that use them. This Bluetooth controlled Roomba is a prime example. They are using their WiTilt module to send the Roomba direction information. Plans and code are available on their site so that you can build your own. I am looking forward to see what will come next. How will they top the roomba and the GPS Wall Clock project.
“It’s a very simple idea, get some tilt values, translate them into throttle and radius commands that the Roomba can understand, and then transmit them over the Bluetooth wireless link. But get ready for some technical talk and a breakdown of ADCs, serial com, and some funky math.”
