Research Activities

♦ Wearable wrist contour measurement device for hand gesture recognition
To realize a future sophisticated interface, we are developing a watch-type wearable device. This device measures the wrist contour using arrays of photo-reflectors and converts the wrist contour data to the label of hand gestures using machine learning techniques.

♦ Automatic construction system of modularized rail structure
The objective of this system is decommissioning operation at the Fukushima Daiichi Nuclear Power Plant (TEPCO), where humans cannot enter or work inside. This system constructs a rail structure platform that enables other robots to move easily in three dimensional space.

♦ A Tablet Interface for a Direct Vision Teleoperation of an Excavator
This study examines a new control system for an excavator using a tablet device. To realize an intuitive interface, we propose novel graphical user interfaces (GUIs). The experimental result concludes that proposed two GUIs superior to the conventional interface in task execution time, accuracy, and subjective usability evaluation.

♦ High-speed and Large-payload Ceiling Mobile Robot UsingCrawler (HanGrawler)
HanGrawler is a ceiling-mounted mobile robot with high-speed mobility and the ability to freely select and adjust its route under a ceiling plate. HanGrawler hangs from the holes of a perforated metal ceiling plate using newly developed mechanically constrained hanging mechanisms mounted on crawler-type traveling equipment. HanGrawler can travel linearly at 1.0 m/s, turn at an 8.5◦/s rotational speed, and carry a maximum load of 60 kg.

    Future Plan

    The discovery and establishment of basic and general knowledge and technologies are important tasks.
    My intention is to deploy such knowledge and technologies in real industrial and service applications, so, I welcome collaboration with various private companies and research institutions.

    Messages to Students

    I think the integration of creative design and computer science is quite important for conducting novel research. I am always pursuing ways of designing beautiful yet functional shapes and software.
    I want to share the pleasure of designing and developing novel things (robots, devices, software, and so on) with many students.
