The NXT
Big Thing
#10
HiTech Fetch!
By Greg Intermaggio
What’s crackin,
roboteers? In last month’s
edition of The NXT Big
Thing, we used HiTechnic’s
compass sensor combined
with the standard
ultrasonic sensor to make a
robot that can head due
North while avoiding
obstacles.
This month, we’ll be exploring yet another sweet sensor
from Hi Technic: the infrared (IR) Seeker sensor V2. You’ll
need an IR Seeker V2 and a Hi Technic infrared electronic ball
— both of which can be found at Hi Technic.com.
This article will assume that you’ve already purchased
the IR ball and an IR Seeker V2 sensor, and downloaded and
imported the programming block into the NXT software.
Download the block from Hi Technic’s website and import it
by clicking Tools > Block Import and Export Wizard.
