Brain-machine interface technology enabling control of a robot by human thought alone

March 3, 2010

HONDA | Honda Research Institute Japan Co., Ltd. (HRI-JP), a subsidiary of Honda R&D Co., Ltd., Advanced Telecommunications Research Institute International (ATR) and Shimadzu Corporation have collaboratively developed the world’s first Brain Machine Interface (BMI) technology that uses electroencephalography (EEG) and near-infrared spectroscopy (NIRS) along with newly developed information extraction technology to enable control of a robot by human thought alone. It does not require any physical movement such as pressing buttons.

This technology will be further developed for the application to human-friendly products in the future by integrating it with intelligent technologies and/or robotic technologies. During the human thought process, slight electrical current and blood flow change occur in the brain. The most important factor in the development of the BMI technology is the accuracy of measuring and analyzing these changes.

The newly developed BMI technology uses EEG, which measures changes in electrical potential on the scalp, and NIRS, which measures changes in cerebral blood flow, with a newly developed information extraction technology which enables statistical processing of the complex information from these two types of sensors. As a result, it became possible to distinguish brain activities with high precision without any physical motion, but just human thought alone.
