This is a creature beloved by children and adults alike for its simple, loving nature and its fun to hack Furbies anyway.

You may begin with skinning the furby. You will have to clip a ziptie at the base of the back of its skin first then you will have to clip little stitches connecting the skin around the face area. Then connect simple touch sensors to your PIC use the first circuit depicted below. To control motors from a PIC or other microcontroller one must use an H-bridge. Make bump sensors to keep the furby from driving endlessly into a wall. You will have to write a program for your PIC to utilize the sensors.
