Electra has a new body, with the servos still mounted on the original
polycarbonate frame, which raises them approximately 1cm from the
base of the robot. This meants that they only stick out 2mm from
under Electra. They are 45mm polypropylene lined with Dycem.
The battery and receiver are wired in place with gardening wire.
The weapon servo is a Futaba SD-200 with a connecting rod attached
from the servo horn to two holes in the polycarbonate flipper. The
connecting rod is made from 1mm copper wire.
Screws sticking out of the sides and some extra plastic at the
back prevent Electra from resting where it can't drive or self right.
Electra is starting to look like a working robot now. A couple
of things still need to be sorted out: It doesn't self-right, it's
slightly overweight, and the linkage from the servo to the flipper
is problematic. The movie below shows that in order to keep connected
between the wheel and the flipper, the rod has to continuously change
its length. My rod didn't. This meant that the flipper was buckling
as it moved.
