Although the covering is optional, it makes the kart look cooler. More impor-
tantly, a covering prevents your kids or pets from poking a finger or paw
where they shouldn’t and pulling wires loose.To build the kart itself, follow these steps:- Place the breadboard, battery packs, caster, and power switch on the
(^1) ⁄ 2 " PVC or plywood sheet, as shown in Figure 11-33.
This will help you to determine how large to make the base of the kart.
We chose a^1 ⁄ 2 " PVC sheet, 6^1 ⁄ 2 " wide and 9" long, which can hold all the
components and still leave enough room to rest the top of the kart on
the base. You can use a pencil to mark where to cut the^1 ⁄ 2 " PVC sheet.
- Mark a location between the breadboard and the bumper switch
where you will drill a hole to feed the wires to the motors. - Use the base of the castor as a template to mark the four holes you
will drill to mount it to the body.
Figure 11-34 shows the marked PVC sheet.
