THE MOTORIZED CHAPTER

PLATFORM

he motorized platform is a most important part of
TQuestor’s construction. It not only supplies the robot with
mobility, but contributes to its personality and appeal.
Although simple in construction, the platform outlined in this
chapter is capable of carrying 50 pounds of robot. To start its
construction, the first job to perform is to prepare the motor-
ized wheels that propel the platform.

PREPARING MOTORIZED WHEELS

Once you have obtained the motorized wheels, study them
and learn how they operate and how they are assembled. This
is important because you must disassemble the wheels in
order to prepare them for attachment to the platform. Be
careful not to lose any of the smaller parts and work on only
one wheel at a time. Figures 1-1 and 1-2 show an assembled
and disassembled wheel.
To disassemble the wheel, first remove the motor and gear-
box assembly held to the side of the wheel’s frame by three
small screws. On the opposite side of the frame is a cotter pin
that holds the wheel’s axle and frame together. Remove this
pin (this is done easily with a pair of needle nose pliers) and
pull the axle out from the other side slowly. As you pull the
axle out, four small spacing washers, two red plastic and two
metal, will fall from the frame along with the wheel itself and
the wheel’s large white driver gear.
