CHAPTER FOUR
USING THE REMOTE CONTROL SYSTEM
The remote control system operates much in the same way as
the temporary control box did. In the control box the position
of the switches, up for forward, center for off, and down for
reverse, along with their combinations, dictated the direction
of the robot. With the remote control system, the control
sticks on the transmitter take the place of the switches of the
temporary control box. Unlike the temporary control box,
however, the transmitter cannot control the speed of the robot
because the pots are no longer at the controls but on the robot
itself. This means that you will have to calibrate Questor’s
motorized wheels and preset the robot’s speed before you use
the remote control system, a small price to pay for wireless
control. As I noted before, if your remote control system has a
third channel and thus a third servo, you could remotely con-
trol other robot functions. This extra servo is controlled by the
sideways movement of one of the control sticks.
Congratulations! You have just completed the last major
component of Questor’s construction! The rest of the book
covers various subsystems within Questor as well as the cos-
metic aspects of the robot’s construction. If you plan on build-
ing a duplicate of Questor, the following chapters detail the
rest of his construction. However, it is my hope that you will
use them as a guide to create your own individual robot
servant.
