Got your parts for the Make: Robot Build contest, and want to build
something with them, but not sure exactly what yet? Strapped for
time, and want some results fast? Then we have the perfect tutorial
for you: The one hour coasterbot! This basic design probably won't
win you many awards, but it will get your bot moving! The tutorial
is broken into to two phases, control system and chassis. In the
control system portion, we'll cover how to take the electrical
parts from the Jameco Robo...

Robot Build: Using an L293 motor controller
In the latest Make: Robot Build Newsletter, Matt Mets wrote a piece
introducing motor controllers and linked to an ITP article on using
an L293NE motor controller. In the Robot Build area of the MAKE
Forums, Alan Kilian pointed us to this other excellent tutorial,
Control Your Motors with L293D, on Let's Make Robots. It has very
clear breadboard images and shows you, among other things, how to
add a few capacitors to your circuit to smooth out the current.

in the Old Country. (Becky is building a sweet-looking CoasterBot

Have you customized your MakerBot chassis?
MakerBot has provided CupCake CNC chassis DXFs on Thingiverse and
their own site for some time now, allowing you to cut out your own
chassis if you have access to a laser cutter. You can even order
the parts from Ponoko if you don't. What I want to know is, what
have people done with these designs to customize them? Thingiverse
user syber cut his chassis out of acrylic -- apparently the
material has a tendency to crack, which is why MakerBot went with
wood. There is also the option of engraving using the laser, rather
than merely cuttin...
