研究実績の概要

1 conference paper (as a co-author) and 2 journals (as a first author) have been published in this fiscal year.
The preliminary result of the first wearable sensor that can measure 3-axis force from human hands has been published at the Robomec 2017.
This device will be used for extracting human manipulation skills and later for teaching a robot.
A soft digital skin sensor (uSkin) for robot hand has been developed, was demonstrated at the ICRA 2017 - Soft Component Technologies Challenge (won a 2nd place award), and has been published at the IEEE RA-letters.
Compared than other sensors, it has a 4 mm thickness, can measure 16 x 3-axis force in 27 x 28 mm area, and requires only 4 wires.

理由

Although 3-axis force data can be extracted from a human finger using a wearable sensor (i.e. while manipulating the stick of wayang puppet), teaching a robot to replicate a similar motion is not possible using the current robot.
This is due to the majority of end-effectors (robot gripper) available in the market are usually do not have a built-in tactile sensor to perform a force control.
Therefore, a tactile sensor for a robot gripper has to be developed first and its development was initially planned to be conducted in the next fiscal year.
However, I realized that integrating these two devices could be a challenging task and would be better to be conducted at the earlier stage so that if some critical adjustments are required, it could be found as soon as possible.

今後の研究の推進方策

Force vector on human fingers generated during an object manipulation will be recorded using a wearable sensor. The recorded human finger motion data will be reproduced using a robot gripper covered with a skin sensor through force control. A machine learning model such as neural network will be utilized to find parameters for mapping the wearable sensor data into robot gripper movements.

A real-time beat tracking system for gamelan music will be developed using HARK-Music to obtain its SIRE (Strength, Intensity, irRegularity, and Extent) representation for a direct mapping of emotion from music to robot movements.

Finally, all results will be submitted to an international journal such as RA-Letters or IEEE Transactions on Robotics and Automation.
