Bit the RoboDawg uses an IR emitter and IR photodiode pair at 3 cardinal points (north, east, and west) to determine the direction it should move. The user attaches the IR emitter (BitBeacon) to their back and Bit detects the light source and follows it. We would also like to add voice commands such as come and stop to override the BitBeacon signal. But those are just nice features. :) Bit will prove to be the perfect family robot dog for the hacker.
I'm working on this project with a couple of friends: Shadman Jubaer, Curtis Slaubaugh, Shubhankar Takle, Sriram Boppana, Greg Berglund, and Axel Masquelin. Follow along with us! Or join if you would like.
