NSK has developed a robotic guide dog that uses external recognition technology and guidance functions.
NSK has developed a four-legged, wheeled robot that utilises a newly developed external recognition technology and guidance function to detect the position of stairs, autonomously recognise the shape of the stairs and then guide the user up and down staircases.
The robot developed by NSK is equipped with drive wheels on each of its legs and is highly capable of manoeuvring over flat and stepped terrain. It is also capable of autonomously recognising stairs through the use of independent processing of external information detected through image and distance sensors, and then guiding the user up and down staircases.
This robot resulted from the development of technology aimed at achieving an autonomous robot capable of assisting human eyesight. This technology has potential application as an alternative to wheelchairs, guide dogs and service dogs. NSK exhibited this product at Tokyo Big Sight at iREX 2011 (International Robot Exhibition), where visitors had the opportunity to see a demonstration and gain insight into the expanding needs of the market. NSK will perform on-site verification in the actual market in order to confirm the practical use and safety of this product.
To date, NSK's involvement in robotics has been focused on the supply of products such as bearings, linear guides and ball screws. In 2007, NSK integrated advanced mechatronic sensor technology with the machine fundamental and component technology NSK had cultivated over the years to develop a robot guide dog capable of autonomous recognition of stairs and the ability to ascend and descend staircases. In this latest version of its robot guide dog, NSK has improved the external recognition, movement and drive functionality and performance, and has added guidance capability.
Through the development of robots designed for human assistance, NSK will continue working to identify underlying issues in this field, engaging its four core technologies - tribology, materials, analysis and mechatronics - to create robotic solutions to real human needs.
