PART 2:
Building the
CIRC Bot
Amateur
robotics is FUN.
Amateur robotics
is EDUCATIONAL.
Amateur robotics
is EXPENSIVE!
Figure 1 shows the complete CIRC
Bot. The main body of the robot
is a solderless breadboard on a
plastic frame. If you have been reading
SERVO for awhile, you have seen other
breadboard bots (and if you have read
Nuts & Volts since the mid-1990s, you
have seen several more). The big
difference between this robot and the
others that have been presented is that
it is built to a tight budget. Most of the
time, a beginner’s robot is shown with
a BASIC Stamp for its microcontroller
and modified servos for its motors.
Both of those choices are made with
FIGURE 1. CIRC Bot.
Last month, you
purchased the basic
hand tools and
supplies you need to
build a robot and
you learned to
solder. This month,
you will be building a
complete robot. This
robot will be more
than just a platform.
It will be mobile,
sense its environ-
ment, change how
it moves based on
what it senses, and
be easily modifiable.
