Carrollton's After School Robotics - From NXT to NAO
By Maria Teresa Valle
The Intermediate School Robotics program continues its participation in the FIRST Lego League and broadens its scope to include
coding and NAO Humanoid robotics.
Students begin the year with the FIRST Lego League "Trash Trek” project by designing and building their own robots. Working
alongside High School Robotics students and faculty, Intermediate students learn, to. use NXT "Drag & Drop” tiles to program their
robot in readiness for task completion1 ,
After gaining an understanding of the computational method required to move their Lego NXT robots, the students are introduced
to and construct an Arduino Robot. The Arduino Robot uses a C Style language, compiled with the Arduino software (www.arduino,
cc). Students are tasked with maneuvering their bots around a tabletop course, without the use of sensors, and are required to code
the Arduino line .by line, .Using delays, motor control ana breaking, students are able to address the mismatch of motor efficiencies
and compensate power output to each motor to level the direction.
The focus at the end of the semester is' On NAO robots and exploring the possibilities with the robot's speech, movements, and
other options.. Students capture the posture positions of their designs, map and Connect the string of events, and play their program
in orderto learn how to refine the speeds and timings of the sequence.

Assisted by High School students Donatella Donado T 8, Alex Gomez and High School faculty Ms. Natalie Eskert, Mr. Matt
Jensen and Ms. Maria Sagarduy, the Intermediate students acquired the skills to enhance their continued participation in the
Technology program.
