Step 4: Battery Shelf Preparation
Figure 4a
As shown in Figure 4a, the Battery Shelf components consist of a Delrin shelf, (6) 1/2” tall, round
aluminum standoffs, and (6) 4-40 x 5/8” screws.
The physical sizes of SLA batteries differ depending on brand and capacity. Figure 4b shows typical
locations for standoff placements, for the batteries that come with the Eddie platform. Mount the
standoffs in hole locations that provide the tightest fit for the batteries that you’re using.
Place the Delrin shelf so that the Parallax Logo is face down, and attach the standoffs as depicted in
Figure 4b.
