Robot-integrated microfluidic chip is a promising tool to realize mechanical characterization of a single cell with high throughput and high accuracy. The microfluidic chip used in our system has a pair of mechanical microprobes to measure deformation and reaction force of cells. In our previous studies, we measured the elasticity of cells in this measurement system. However, there were some problems...
We developed a ‘hybrid actuator system’ to precisely control the position of a micro-particle at high speed in a microfluidic chip. The hybrid actuator system benefits from two actuator systems by combining an electroosmotic flow generator and pressure-driven flow induced by a piezoelectric actuator-driven syringe pump system. We also implement an image processing algorithm using a high speed vision...
"A fair measurement is possible only under one unknown", which is an iron principle in instrumentation technology. In other words, it is difficult to evaluate two unknowns simultaneously, through the measurement of just one output from sensor. The main topic is to evaluate cell deformability through a micro fluidic channel. When a cell passes through a micro channel whose size is a bit smaller...
In this paper, additional manipulating function for limited narrow space with omnidirectional driving gear was described. The validity and advantage of the proposed function was also confirmed through experiments using the actual prototype of the planar omnidirectional driving gear units for the parallel gripper.
The finger mechanism equiped with omnidirectional driving roller is shown. The omnidirectional driving roller has two active rotational axes at the touching point. The finger mechanism with this roller can manipulate the grasped object with any arbitrary directional axes. Prototype model has been developed and basic motion of the finger has been confirmed though the experiments.
This paper describes a combination mechanism of a wheeground a paddle to realize an effective movement on the border of ground and water. For the conventional mobile mechanisms on water or on ground the combination of the mechanism to the body of the robot separately, and each one can be the interruption to the other in each field. In this research, we propose a hybrid mechanism of a wheeground a...
This paper discusses an active shaping method for an unknown rheological object by considering the characteristics of viscoelasticity. By utilizing a four-element model for approximating the dynamic characteristics of object's deformation, we drive the deformation decomposition into the elastic response and the plastic one. For shaping the object, we then propose a two-phase strategy for controlling...
