FIGURE 7 NOTE:All itemsare from www.robotmarketplace.comunless notedotherwise.
Figure 1 is a CAD model of
Apollyon drawn in Solid Works. Some
minor changes were made, but most
of the parts are almost identical to
the ones in the drawing, for example,
the side and internal frame rails, as
well as the horns that are used to
catch other robots. The horns are
steel and the rest of the frame is
6061 aluminum (see Figure 2).
The sides of the frame are
lined up to show the profile of the
chassis, shown in Figure 3. The
holes in the top, front, and bottom
of the plate are tapped to allow
armor to be bolted directly to them.
Figure 4 shows the chassis with
the baseplate, drive motors, and internal portion of the front armor installed.
Figure 5 shows a mostly
assembled Apollyon sitting inside
the chassis of my 60 lb robot Ruiner.
In Figure 6, Apollyon has been
painted, the front steel wedge has
been mounted, and the robot is
almost ready for competition.
Take a look at Figure 7.
You’ll see an internal shot of
Apollyon the night before the
“Wreck the Halls” event in
Greensboro, NC. This shows
the layout of the electrical
components and the battery
mount. The piece of PVC pipe
in the back left of the robot
serves as a power distribution
block and battery mount.
Figure 8 shows Apollyon at
Wreck the Halls being prepared for
the first match of the competition.
Apollyon won the 12 lb class
with a 3-1 record (see Figure 9).
The damage was all cosmetic
and easily repaired. The shaft collar
on the visible axel was torn off in
combat. A new front wedge is
being designed to reduce
impacts on the chassis. SV
