Orlando Antongiorgi,
an East Technical High School student and NASA Glenn summer intern,
partnered with NASA Glenn Research Center Engineer, Mike Krasowski,
to design a circuit to monitor a radiometer experiment.
This experiment was
scheduled to fly aboard the Mars 2001 MATE experiment. He was
given a short course in op amps, a pile of parts, and a breadboard.
He was then told to make a circuit that would auto zero a radiometer
amplifier circuit for the Mars 2001 MATE experiment.

The signal from a radiometer
is often as small as if not smaller than the input offset voltage of
an op amp. Hence, the output signal of the circuit can be more representative
of amplifier error than of the input signal. Orlando's circuit lets
us measure the op amp's contribution to the output and allows us to
subtract it from the incoming signal.
The circuit, with a digital
to analog to converter replacing a potentiometer and an analog switch
replacing some jumpers, is in the flight hardware shipped to NASA Johnson
Space Center.
Orlando is now in his sophomore
year of studies at Case Western Reserve University in Cleveland. Inspired
by his work with Mike, he chose Electrical Engineering as his major.
He returned this year as
an alumnus along with another former East Tech student, Nate Gucik,
to aid East Technical High School with the building of their FIRST robot
at the Advanced Manufacturing Center at Cleveland State University.
His title is "Student Engineer," and he along with Nate traveled with
the team to Epcot in 2001.
Nine years ago, East Technical High School was slated for closing due
to an enrollment of 900 and only 43% of the students passing the State
of Ohio Proficiency Test. Now East Technical High School has an enrollment
rate reaching 1400 and 71% passing the State of Ohio Proficiency Test.
Nine years ago, NASA Glenn
Research Center engineers and technicians worked with students at East
Technical High School to build a robot to compete in the National For
Inspiration and Recognition of Science and Technology (FIRST) Robotics
Competition. Students from East Technical High School involved middle
students in LEGO competitions and community service activities. Since
East Technical High School has been involved in FIRST, there have been
more students applying to become part of the NASA GRC/East Tech FIRST
Robotics Team than students trying out for sports teams. When NASA Glenn
Research Center first took these students to Orlando, FL to compete,
they were the only urban school out of 85 teams. These students placed
in the top ten at the FIRST Robotics Competition nine years ago. Since
then, the NASA GRC/East Tech FIRST Robotics Team has received high recognition
and continues to compete strongly.
Some of the accomplishments
are as follows:
-
1998 Great Lakes Regional
FIRST Robotics Competition, "Xerox Creativity Award" (Ypsilanti,
MI)
-
1998 FIRST National Robotics
Competition, "National Chairman's Award Finalist" (Orlando, FL)
-
1998 National FIRST Invitational
Robotics Competition, "Havoc on Capital Hill" Champions (Washington
D.C.)
-
1999 Great Lakes Regional
FIRST Robotics Competition, "Delphi Power to Simplify Award" (Ypsilanti,
MI)
-
1999 National FIRST Robotics
Competition, "The National Chairman's Award" This is FIRST's most
prestigious award, which is awarded to the team that demonstrates
the best partnership between the school and their corporate sponsor.
Nine years ago, the NASA
GRC/East Tech FIRST Robotics Team was the first NASA sponsored team
in the Agency. To date, NASA Administrator Dan Goldin has provided more
than $2M annually to sponsor 118 NASA teams.
During the 1999-2000 school
year, Glenn Research Center funded and supported two additional FIRST
teams: Rhodes High School, Cleveland, Ohio; and Eastmoor Academy, Columbus,
Ohio.
During the 2000-2001 school
year, two additional FIRST teams were added: Beachwood High School,
Beachwood, Ohio; and Max Hayes Vocational School.
In 2002, NASA Glenn Research
Center is planning to continue to expand its involvement in the FIRST
program by hosting the Buckeye Regional FIRST Robotics Competition in
Cleveland, Ohio and sponsoring 20 of the FIRST teams that will attend
the event. This will be the first regional held in the state of Ohio.
