The first lens head robot that I made was a HUGE hit at the EXPO that I went to last year. So this year, I intent to bring ALL FOUR lens head robots. I have already built a second one. Here is the thread for it: http://www.zealot.com/forum/showthread.php?t=173362&highlight=Lens head robots I am not going to type much with this thread. I will let the photos do more of the talking. So please ENJOY this thread. I am starting off with the HEAD.
