- Able to overcome cables and uneven floor heights, and accurately recognize
human voice within background noise -
Tokyo, Japan, 18th June 2010 --- Hitachi, Ltd. (NYSE : HIT/TSE : 6501, hereafter Hitachi) today announced the development of technology enhancing the practical application of the human symbiotic robot, "EMIEW2", for the office and other environments. The newly developed mobility and voice recognition functions, enhances the functionality of "EMIEW2", enabling it to overcome cables or uneven floor heights as well as accurately recognize human voice within various background noises. Based on these results, Hitachi will be accelerating its research for the practical application of "EMIEW2" in providing guide or surveillance services within various environments such as offices and hospitals.
Recently, remarkable progress has been made in Robotics, with various types of humanoid robots being announced. Hitachi has been developing a human symbiotic support robot with a view of applying it to the service sector. "EMIEW2" is a light-weight compact robot, developed by Hitachi in 2007, capable of autonomous movement using a two-wheel mechanism to move at 6 km/h, about the same pace as a human walking quickly.
To ensure stable operation and appropriate control of "EMIEW2" in a actual environment such as offices or hospitals, the ability to detect unexpected obstacles such as differences in floor height due to cables, mats or thresholds and various unexpected noises such as background music or peoples' voices, and were considered an issue.
To solve these issues and increase the practicality of "EMIEW2" in offices, etc., Hitachi developed new technology to enhance mobility and voice recognition as follows.
The next step will be to collect data through pilot tests to further improve practicality with a view to the practical application of a human symbiotic robot which can provide guide or surveillance services in a safe symbiosis with human.
"EMIEW2" is based on new developments on technology developed as part of the New Energy Development Organization (NEDO) commissioned project on the practical application of next-generation robots (prototype development support program) for "EMIEW" in 2005.
