wiring complete, Keres
is ready for testing.
Placing them forward of the motor
helps to shift the weight balance
slightly forward of the drive wheels,
which should reduce how often the
front of the robot lifts off of the
ground. The receiver and battery
are behind the drive motors near a
spot that allows for the future
addition of a power switch.
An afternoon of soldering later,
and Keres was nearly ready for
testing. I tossed the batteries on the
charger and spent a bit of time
"neatening" up the wiring and
securing the weapon motor wires in
a way that would keep them from
getting caught on anything. Not
long after that, the batteries were
fully charged and Keres was ready
for the first test.
Testing went well, and all
systems performed as expected.
The new drive motors resulted in a
very nimble robot, and the weapon
appears to pack a decent punch
without breaking itself. SV
