Bob Comer I teach computer programming classes at Austin Community College. When I have spare time I work with students in our Semiconductor Manufacturing program, helping them write programs to control manufacturing equipment. I am currently working on a small hexapod robot. I have also played around with the Lego Mindstorms Robotic Invention System kits for a few years. During the summer I usually teach a Robotics mini-class for middle and high school students using the Lego kits.
