Press Release

NSK Welcomes Visitors to iREX 2015

Announcement of Products and Technologies for Higher Performance in Robots

NSK Ltd. (NSK; Headquarters: Tokyo, Japan; President and CEO: Toshihiro Uchiyama) today announced that it will exhibit at International Robot Exhibition 2015 to be held at Tokyo Big Sight (Koto-ku, Tokyo) from Wednesday, December 2 to Saturday, December 5 with the theme of Your Real Partner™.

This year will be the first year that NSK will have exhibits in both the Industrial Robot Zone and Service Robot Zone. In the Industrial Robot Zone, NSK will use dynamic and video displays to showcase its latest technology for smarter robotics such as sensors and other products for longer life, higher rigidity, faster speeds and greater compactness.

NSK is a participant in the Kanagawa Sagami Robot Industry Special Ward Robot Demonstration Support Business. The company will be exhibiting its products in the Kanagawa Pavilion's booth.

Guide robot with indoor navigation and obstacle avoidance

(1)Guide robot with indoor navigation and obstacle avoidance
Wheeled robot that guides users to the entered destination while recognizing, autonomously avoiding and stopping for obstacles. Designed for helping all patients around large hospitals, especially the elderly and visually-impaired. NSK will have a demonstration of this robot at its booth.

In addition to the conventional obstacle avoidance and navigation guidance features, NSK has made the following improvements leading up to practical application:

  • Height optimized for the elderly
  • Touch panel for entering destination
  • Music plays while in motion to increase awareness of those nearby
(2)Proximity sensor

This product under development uses an array of infrared LED sensors to quickly detect the distance to and location of objects over a wide range. In addition, it employs a flexible printed circuit board to make it usable in a variety of shapes of robot arms and for easier assembly in production lines. It has a blind spot-free detection range from 0 to 300 mm, whereby making situational controls possible for adjusting robot speeds and stopping robot movement as necessary.

(3)Dual axis integrated motor

This product under development is designed with simpler and more compact actuator structures. In addition, through application of NSK Megatorque Motor™ technology, NSK has realized 2.62 million count/rotation high resolution. Combine with dual axis integration, this technology makes for simpler cable and wiring layout as well as higher performance of actuators and less maintenance thereof.
