PixyCam by CMU (yes!) and Servo Shield by Adafruit
Well I’m certainly happy. My idea for this Arduino project was to have my RC car follow me around like a pet, fast if I’m running, slow if I’m walking, backwards if i’m walking towards it. And I’ve found the perfect sensors. First, is PixyCam by CMU labs! Yes, homegrown here in Carnegie Mellon. This camera is really impressive, crunching huge amounts of data into really simple color-tracking signals. It allows a “weak” computer like Arduino to use a complicated sensor like a camera (millions of pixels) at 50fps(!) to track the location, distance and number of objects, color coded, to create sight-following bots or robot-followers etc. This is amazing! Just what I needed to make my rc car a pet. The other, more simply, is a shield provided by Adafruit to more accurately control more motors than just the simple Arduino board. Although I dont need this since the board is sufficient for my two-servo need.
