Upper Limb Prosthetics and Orthotics

We are conducting research and development on the mechanisms and control methods of prosthetic limbs with the aim of social reintegration and work support for persons with limb loss. We also focus on research on measurement and analysis for the evaluation/assessment of prosthetic limb.
  • Research Theme
  • Multimodal sensor-controlled transradial prosthesis
  • Myoelectric + Body powered Bowden cable mixed interface and control for upper limb prosthesis
  • Evaluation test methods for Body-powered upper-limb prosthesis components
  • Activity prosthetic terminal device
  • Powered-prosthetic hand for infants
  • Pediatrics upper limb prosthetic socket design to assist play
  • 3D motion analysis of compensatory movements for prosthetic hand use
  • Myoelectric manipulation trainers for infants

Robotic for assistive systems

We are conducting research to introduce robot technology not only to support the daily lives of people with disabilities but also to physically assist caregivers in nursing tasks and to support the recovery of motor and sensory functions of the limbs.
  • Research Theme
  • Upper limb therapeutic systems
  • Hand therapy system
  • Hydraulic bilateral servo type transfer assistance robot
  • Robotic teaching aids for assisting standing up movements
  • Multi-motor control
  • Robotic leg for ball kicking

Bionic Systems with Mechatronic Design

We are conducting research on a measurement system that combines electromyography sensors, joint angle sensors, and other sensors for measuring motor function with sensors for physiological signals such as respiration, blood flow, body temperature, and sweating (skin potential).
  • Research Theme
  • Inner-socket multimodal-sensor atmosphere control
  • Ultrasonic blood flow diagnostic system
  • MyoElectric sensor and signal processing
  • Multimodal sensor control of Prosthetic hand and wrist
  • Surface-mounted joint angle-meter
  • Respiration measurement using a depth sensor
  • Driving seat vibration disturbance presentation simulator

Haptic Systems for Skill Improvement and Transfer

We are conducting research to develop devices and high-precision measurement instruments with improved operability by combining sensor measurement, signal processing, and control technologies. This includes quantifying the operational skills of manipulating tools with the hand using robotic sensing technology and providing haptic feedback based on information obtained from image processing technology
  • Research Theme
  • Hydraulic/pneumatic bilateral servo system
  • Haptic recorder for surgical cutting procedures
  • Pedestrian crossing guidance system for visually impaired - people using image processing and haptic feedback
  • Center of gravity sway system for small mammals
  • Steer-by-wire system for autonomous vehicles
