Squirt is an attempt at a robopet for my daughter. He is run by a PIC16F84 and an L293 motor driver. The motors are 6V gearheads from a surplus catalog and the treads are a kit from a hobby store. The ultrasonic transducers are non-functional as yet, but I have found that the anthropomorphism that they add has made this my favorite robot so far.
