Capitol College hosted an FTC working session and seminar on Saturday, October 6th from 9 a.m.
to 3:30 p.m. The “Ring It Up” field was erected in the Student Center. The seminars were
held in the auditorium and some of the class rooms. We forgot to pack the metal poles that
hold the center scoring rack. Other than that, the field set-up was smooth.
David presented the Samantha seminar from 10 to 11 a.m. The ten attendees learned how to
mount, wire, and connect the Samantha module to the robot. They learned that the module
connects the NXT Mindstorm to the Field Control System (FCS). The FCS provides the link
between the student’s joystick controllers and the robot during a match.
Allan Cass held a beginning RobotC seminar and a more advanced RobotC seminar. There were
fifteen attendees at the first seminar. The use of the NXT Mindstorm (aka the brick) was
discussed and also the basic electrical wiring of the brick, motor/server controllers, motors,
switch, and battery. The data wiring of the robot determines the configuration of the pragmas.
Manual operation of the robot was the focus. Interpreting the output of the joystick
controllers was shown, which included conditional statements. Programming of the joystick's
dead zone and how that affects the programming of the motors was discussed.
Mary helped Allan during the second seminar by displaying a sensor robot that had been built
the night before the event. They discussed motor encoders, a sensor mux, a touch sensor, an
IR seeker, a light sensor, and an accelerometer. Thirteen attendees were given an overview of
these sensors. The focus of this seminar was the sensors and their uses. The code was shown,
but not discussed in detail.
Ten rookie teams attended the combined workshop and seminar (shown below). Two veteran teams
were in attendance (3253 Carroll Metal Lions and 2843 Under the Son). Under the Son was
on-hand at the working session to help rookie teams build their robots. Most of the teams were
well on their way to having robots that could respond to joysticks. One team was able to drive
their robot on the field before the end of the day. Another team was completing the wiring of
their robot, but encountered a problem where the battery wire was too large to fit into the
motor controller. Erik showed them how to flatten it with a pair of pliers. Unfortunately,
two teams do not yet have their kit of parts.

The Thurgood Marshall Academy team is ready for a part of the competition. They told us that
they had been working on their dance moves. We (at least Mary and Lydean) can’t wait to dance
with them during the breaks between matches.
Below are the slides from the Robot C workshop and Samantha workshop in PDF form, to the right
they are provided in Power Point form.
Mary programmed the sensor robot to follow the IR beacon. The robot would turn in the
direction of the IR beacon using an IR sensor. It would drive forward in the direction of the
IR beacon. She programmed the ultrasonic sensor to halt the robot when it was too close.
