The design can also be seen in the six-legged kit addition to the Boe-Bot. Jameco and others carry the kit. There's just something about a multi-legged robot that is so cool!
So I decided to combine the Herbie brain with the Boe-Bot six-legged body and throw in feelers.
Step 1: The chassis
When I was happy with the mockup, I cut aluminum side panels from 5052 aluminum. I think it's 1/8 inch thick.
Then I used pieces of flat brass to make the leg pieces.
#6 bolts 1 1/2 inches long made the longest pivot points for the legs. Looking at the top view you can see that I used other lengths of #6 bolts.
I added lengths of brass tubing over the bolts to hold the body away from the leg joints. When I got the legs aligned correctly, I used loctite to keep the bolts and nuts from loosening during walking.
