It was a beautiful spring day in April
of 2005. The sun was shining and there
were a just a few cotton puff clouds
in the azure sky. The humidity that
I have come to expect in Tokyo was hardly
perceptible and it almost felt like
Southern California weather. A gentle
breeze was wafting along the narrow
streets of central Tokyo as we made
our way towards the old quarters. The
narrowness of the streets and the ingenuity
with which the Japanese utilize space
has never ceased to amaze me. We walked
past a bicycle parking area, where the
bicycles were stacked one on top of
each other on a specially designed rack
and used up every inch of the available
space. There were a few hardy Sakura
trees with blossoms still blazing brilliant
white and pink swaying majestically
in the wind, seemingly oblivious to
the commonly repeated assertion that
the cherry blossom season was over.

The old homes and building that lined
the cleanly swept road, along with the
warm smell of cooking, seemed to me
to be a scene right out of a history
book. I half expected to run into Samurai
warriors on their horses and swords
as we turned the corner. I had to remind
myself that this was 21st century Japan,
and we were going to visit one of the
premiere robot builders in Japan. Kondo
Kagaku Co. Ltd. made servomotor-controlled
robots that were used in a variety of
applications ranging from entertainment
to commercial. Kondo represented the
Samurai spirit in the cutting edge of
technology. Kondo is also a long time
customer of MecSoft Corporation and
has used VisualMill since version 3.0
and that is why we were visiting the
company.
We walked into a small office that
had an unpretentious sign, reading “Kondo”.
It looked like a showroom of sorts,
with glass cases lining the walls. The
cases were filled with model automobiles
and trains. A man in a blue uniform
met us at the door. After the usual
exchange of deep bows and polite pleasantries,
he led us to another building. We walked
into a clean room where we had to exchange
our shoes for slippers. We were met
there by another gentleman, the chief
robot designer, who walked into the
room carrying a small robot. The room
had a small table that looked like a
tabletop hockey rink. The engineer placed
the robot at the center of the rink
and then opened his handheld computer.
Robot controlled by 17 servos
With a few keystrokes, he had the robot
walking around the rink. With a few
more keystrokes, he made the robot balance
on one leg and had it perform a cartwheel.
As we watched in amazement at the robot’s
balancing skills, the engineer paused
for maximum effect. Then, with a few
deft keystrokes, he had the robot doing
an imitation of a bodybuilder showing
off his muscles during a competition.
It was hilarious to watch and we couldn’t
but help burst out laughing.
The engineer explained that this particular
robot had 17 servomotors controlling
its various joints, and two gyro controls
in each foot for balance and stability.
The robot itself was controlled by radio
signals that were sent from a device
hooked up to the parallel port of the
laptop. The robot came with software
that included a motion editor to create
and playback motion sequences. These
robots were used in competitions where
two opposing robots would battle each
other to death. Therefore, the ability
of these robots to take a beating, fall
down, and get up on their own accord
was important. He then proceeded to
lay down the robot flat on its back
and typed in a command. The robot accompanied
by various whirring noises from its
motors, slowly but surely stood up erect
on its own accord and lifted both of
its arms up in exultation. It was an
amazing thing to watch. Hello, Terminator!
Once the demonstration was over, we
moved to the production area. Kondo
not only made robots, but all kinds
of radio-controlled equipment, including
remote controlled cars, aircrafts, and
trains. All the designs for the parts
were done using Autodesk Inventor and
then transferred to VisualMill via IGES,
where the milling toolpaths were programmed.
The toolpaths are used to machine prototypes,
as well as production runs of certain
parts. Prototypes are machined in a
Roland MDX-500, while the production
runs are done in a more heavy duty Fanuc
milling machine that boasted a 15-station
tool changer.

The decision to buy VisualMill
was made after the company outgrew the
software product that came bundled with
the machine tool. When 3D machining
and machining efficiency became very
important, they realized they needed
software that they could rely on.

Kondo made the purchase decision after
a thorough analysis of the market and
finally settled on VisualMill, because
it had the right mix of functionality
and ease of use. They also believed
the product was priced right, unlike
several competing products with similar
functionality, which cost at least twice
as much. The company is quite happy
with the performance and functionality
of VisualMill. They look forward to
continue using VisualMill as the product
they design becomes more complex.
After I met the president of the company
and looked around the facility one last
time before we departed, I couldn’t
help but admire the spirit of the people
of Kondo who, from quite humble settings,
were producing leading-edge technological
wonders. We at MecSoft are proud to
be associated with a fine company such
as Kondo and numerous similar companies
across the globe using our products
on a daily basis. As we walked out into
the sunshine on that spring day, I felt
that we were brother Samurai each battling
our own unique challenges in our own
unique way. Kanpai to that!
