Some progress on the bot. A simple thing really but big for me because I am so horrible at mechanical stuff. I had planned to go to Home Depot to get the drawer knob but with all the snow I decided against it. So, I tried to canniblize the knob on my CBABot. I'll have to get a replacement from Mike. Anyway to my surprise I was able to find a standoff of almost the exact correct length that fit into the knob! My robot is now balanced pretty well. The sensors are all equi-distant from the ground. Meaningful testing of the bot is coming soon. I can feel it. I just need to put on light shields on and hook up the H-Bridge to the MCU. After that, its all software. :)
