Step 2: The servo horn will need four of the holes enlarged for the 4-40 screws. The holes need to be
smaller than the screw so that when the screws are inserted they will make their own threads. You can
drill the holes using a 3/32” drill bit, or use an X-acto knife to enlarge the holes as shown below,
depending on which servo horns were included in your kit. If you are using the knife, be sure not to
over-enlarge the holes. By reaming with the knife a little from both the top and bottom, the hole will
be more uniform in size.
Step 5: Remove the wheels from your Boe-Bot. The servos should be mounted with the head toward
the rear ball wheel as in Figure 5. The servo mounting tabs need to be on the outside of the Boe-Bot
chassis. Confirm that the servos are mounted correctly. If your servos are mounted the opposite way,
or are mounted from inside the chassis, remove them and remount as shown.
