A Servo-based 4-legged Walker

Step 2 Build Frame, Fit Motors

First I drilled holes on the corners of the two motor cutouts, then scored along the edge of a ruler from hole to hole with a matte knife. It takes like 20 passes with the knife to get through the Sintra. I got lazy and snapped it after cutting about 1/2 way through.

After cutting out the holes, I test-fit the motors just to see how it worked. (A little too wide, but I got the length just right.)
