Tiny Daffodil Report |
Tiny Daffodil was built to be a
mini-version of the original 12 lb Daffodil. It was
surprisingly effective, winning the antweight championship
at the SECR Farm Fight in Florida, January 2002.

Tiny Daffy's
frame and drive motors. Note the bearings attached to
some chunks of circuit board material. The drum rolls
on those bearings. The MX-50 servos are
really nifty. Weight was a premium issue in this bot
because the drum was so heavy and so was the weapon
motor, so the lightness of the servos helped a lot.
You can get them at
Acroname.

The wheels.
Because of TD's design, it needs big wheels (4"
diameter), and doesn't have any weight to spare. CDs
could have worked, but I saw some CD wheels get broken
at IHXRC, so I decided to use circuit board material.
A rubber o-ring was then glued on the outside to
provide some traction. The nifty hubs can be
bought at ServoCity.

The drum. It was
made from a chunk of 1/16 thick aluminum pipe. The
endcaps were made from delrin with a thin layer of
teflon glued to the inside. |
