Welcome to Hirata Laboratory!!


Actuators and sensor technologies are essential in science and industry for the creation of robots, automobiles, home electronics etc. We at Hirata Lab are conducting research on cutting-edge, next generation actuators and sensor devices that uses new operating principles and new materials. Examples of some of the research being conducted include multiple degrees of freedom actuators, linear actuators that are modeled after the human wrist, contactless torque transmitting magnetic gears, magnetic fluids, giant megnetostrictive elements, thermo-sensitive magnetic materials, and nano ion devices.

In doing research on said devices, we are also developing various coupled computational analysis methods. We aim to elucidate the mechanism of complex systems in coupled physics phenomena that include electromagnetics, mechanics, thermodynamics, and fluids by using the Finite Element Method (FEM) and Moving Particle Semi-implicit method (MPS). Based on the analysis results, we determine the optimum design parameters, and evaluate the best control method for our prototype.

At Hirata Lab, it is our policy that members are involved in the entire process of creating the new device; from the idea proposal, to the analysis method development, design optimization, prototype making, control method development etc.

key words: actuator, sensor, robotics, smart material, finite element method, moving particle semi-implicit method, coupled analysis, control method, computeraided design.
