BUILD REPORT:
Rebuilding Apollyon, Again
● by Mike Jeffries
Since the last build report was written, Apollyon has
competed at Motorama. Apollyon
took terminal damage there while
achieving a 3-2 record, and yet
again needed a complete rebuild.
With the third build, I decided to
focus on reducing complexity and
using the internal space more
effectively.
The major technique change
used in this build was a switch
from primarily tapped holes in
the frame of the robot to a
mostly waterjet cut chassis held
together by a product called
“Nutstrip” that is sold at
Kitbots.com.
Nutstrip is a
piece of square
stock with a
series of
perpendicular
holes drilled and
tapped in it
which allows
parts to be easily bolted to it at
90 degree angles. Another
benefit is that it is much less
expensive and time-consuming to
replace than an entire section of
frame.
