MHI and NCXX Achieve Wiring Reduction in Industrial Robots through New Power
Line Communication Technology 
Industry First, Enabling Dramatic Improvement in Robot Operability 
Tokyo, June 5, 2013 - (JCN Newswire) -  Mitsubishi Heavy Industries, Ltd. (MHI)
and NCXX Inc., a developer and provider of communication equipment and
auxiliary services based in Hanamaki City, Iwate Prefecture, have jointly
succeeded in reducing robot wiring through incorporation of power line
communication (PLC) technology, an industry first. PLC eliminates the need for
the thick power and signal cables that have conventionally been a necessary
feature of robot arms, enabling dramatic improvement in robot operability. The
two companies are now proceeding toward commercial viability. 
Two factors contributed to the reduction in requisite wiring: the
incorporation of a high-speed signal transmission device developed by NCXX into
a robot manufactured by MHI, and the two companies' joint development of
new technology that suppresses external noise influence and signal distortion
during power transmission. 
A variety of tools - hands, sensors, cameras – are typically connected to the
tips of arms of robots used in factory automation applications, support devices
to achieve recovery from disasters, etc. To control such tools remotely
requires not only supplying them with the necessary power but also transmitting
supervisory control signals. Conventionally, these needs have been met by thick
power and signal cables installed on the exterior of the robot's arm - a
configuration that has impeded robot maneuvering. 
With the new PLC-based wiring technology developed by MHI and NCXX, one pair
of thin communication lines simultaneously performs large-volume power supply
and high-quality, high-speed signal transmission. By eliminating conventional
thick power and signal cables from the robot arm, robot operability is improved
Even before now methods have been available to enable simultaneous power feed
and information transmission, "Power over Ethernet," or PoE, being a
representative example. However, such methods have been applicable only in
small electric devices and cannot be used in robots; moreover, the PLC systems
available on the market are incapable of simultaneously supplying power in
large volumes and transmitting signals at high speed under electromagnetically
severe environments. MHI and NCXX's newly developed technology resolves
all of these issues, enabling its application in robots. 
The new technology (joint-patent pending) can be used in industrial robots
used to achieve factory automation, robots on automobile assembly lines, etc.;
alternately it also enables developments in special-purpose robotic fields such
as supporting recovery from disasters. Reducing necessary wiring makes it
possible for robots to perform assembly tasks, etc. within confined, complex
work areas, and to perform post-recovery work smoothly in noisy locations
hampered by numerous obstacles. Going forward, MHI and NCXX plan to enhance
their new technology further in system and PLC module business areas in order
to meet an increasingly diversified range of market needs.
