30 A Fan Controller for a 3D
Printer Enclosure
by Theron Wierenga
I had been working on a 3D printed custom enclosure for
the underwater Quad_ROV recently covered in SERVO
(December 2017 and January 2018 issues). After some
difficulties with ABS plastic, I decided to enclose the printer.
Temperature control was necessary, so here’s what I did.
35 Ultrasonic Radar Refresher
by Dan Harres
If you read last month’s installment, you know how a
piezoelectric ultrasonic transducer works. Now, it’s time to
come up with the circuits that will drive such transducers
and convert their received voltages to useable signals.
40 Embedding the RobotBASIC
Robot Operating System into
the Parallax Scribbler S3
by John Blankenship
Parallax’s Scribbler S3 may be one of the most overlooked
and underrated robots on the market. Right out of the box,
it has line sensors for following
lines, perimeter IR sensors for
detecting obstacles, light sensors
capable of isolating the brightest
light in a room, and wheel
encoders that make accurate
movements possible. Embedding
a custom version of the RROS
makes it one of the easiest robots
to program.
44 RoboGames
Redux
with Dave Calkins
Now in its 14th year, RoboGames
is the premier event that brings
together competitors from all over
the world, with over 50 different
contests to enter in. Event creator,
Dave Calkins offers some timeless
advice for two of the more
popular competitions: Firefighting
and RoboMagellan.
54 Thinking Inside the Gearbox
Twin Tweaks: Twin brothers hack whatever’s put in
front of them, then tell you about it.
by Bryce and Evan Woolley
ServoCity offers a variety of servo gearboxes to supercharge
your servos with strength far beyond what their frail plastic
bodies should be able to handle. Could a straightforward
gearbox really make a servo — normally used for the gentle
adjustment of RC airplane elevators and rudders — capable
of feats of strength? There was only one way to find out.
60 Underwater Robots
Then & Now: Advances in robotics from the past up
through today.
by Tom Carroll
When you’re going to depth in the ocean, there are special
considerations for robots that are used underwater that
don’t apply to ground-based platforms.
