| Outline of Final Research Achievements |
We've been promoted researches on optical rotary link joint that provides a high-speed bi-directional digital link between mutually rotating objects and power transfer function from the fixed side to the rotating part. Coaxial type plastic optical fiber (POF) is used for forming a optical bi-directional digital link, and wireless power transmission scheme is applied for electric power transmission. As a result, the feasibility of optical rotary link joint with characteristic of transmission speed 2 Gb / s and transmission power 8 W with the diameter and length of the connector size can be realized with less than 20 mm and 80 mm respectively. Furthermore, it was revealed that the application area of the optical rotary link joint can be applied to an extremely wide range such as flexible arms of robot, electric cars and other various machine tools where video monitoring / sensing and power transmission are indispensable.
