In the past two parts of the series (May and August 2017), I discussed all of the thought and design work that led to this point in my robot’s construction. Now
we get to the fun part: building and competing!
In Figure 1, we see the robot coming into shape with
the lifter and drivetrain in place. The front is made from L-shaped carbon steel that’s 1/4” thick. The lifter pivots on a
1/2” thick piece of carbon steel as well, and is retained
with the shaft collars.
Figure 2 shows one of the 3D printed supports for the
drive motors. It’s made from PLA at 50% infill with two
shells since these aren’t designed to take much direct
impact but simply to hold the drive motors in place.
The entire build process didn’t truly end until we were
at the event itself. In Figure 3, we see Atrocious right
before its first fight at the event.
Some notable changes made include the added white
UHMW spacer to make sure that the lifter tongue stays
ahead of the front blocker. Additionally, the front wedge
was replaced with some spare 1/8” steel that was welded
together by a fellow builder.
It turns out that the original front block (composed of
