Robots must have similar mechanical impedance characteristics to humans in order make safe and efficient contact. This requirement applies not only the surface but also actuation mechanisms. The objective of this research is develop inherently flexible actuator by realizing backdrivability. A class hydraulic called electro-hydrostatic was applied knee joint humanoid robots satisfy flexibility large torque output simultaneously. paper explains methodology performance evaluation actuators...
The impact of sesamin, episesamin and sesamolin (sesame lignans) on hepatic gene expression profiles was compared with a DNA microarray. Male Sprague-Dawley rats were fed experimental diets containing 0.2% or sesamolin, control diet free lignans for 15 d. Compared to lignan-free diet, caused 1.5- 2-fold changes in the 128 40, 526 152, 516 140 genes, respectively. modified not only mRNA levels many enzymes involved fatty acid oxidation, but also those proteins transportation acids into...
Background Kawasaki disease (KD) is a systemic vasculitis of unknown etiology. The innate immune system involved in its pathophysiology at the acute phase. We have recently established novel murine model KD coronary arteritis by oral administration synthetic microbe-associated molecular pattern (MAMP). On hypothesis that specific MAMPs exist sera, we searched them to identify KD-specific molecules and assess pathogenesis. Methods performed liquid chromatography-mass spectrometry (LC-MS)...
Coronary arteritis is a life-threatening complication that may arise in the acute stage of Kawasaki disease (KD), leading cause systemic vasculitis childhood. Various microorganisms and molecular pathogens have been reported to KD. However, little known about key molecules contribute development coronary KD.To identify causative for KD, we prospectively recruited 105 patients with KD 65 controls four different parts Japan from 2015 2018. During this period, conducted lipidomics analyses...
Woodpeckers have flexible and extendable tongues that they use to reach their prey through tiny openings in trees insect burrows. This unique capability of tongue represents a promising design for tool picking up handling objects unstructured environments. Although continuum robots can produce dexterous movements because few shape constraints, the lack structural stiffness has restricted deployment real-world Inspired by characteristics woodpeckers, we designed robot manipulator...
Essential tremor is a disorder that causes involuntary oscillations in patients both while they are engaged actions and when maintaining posture. Such face serious difficulties performing such daily living activities as eating, drinking, writing. We have been developing an electromyogram-controlled exoskeleton to suppress tremors support the eating movements of these patients. This designed voluntary movement at elbow terms flexion extension: essential movements. In this study, we examined...
The impact of sesamin, episesamin and sesamolin (sesame lignans) on hepatic gene expression profiles was compared with a DNA microarray. Male Sprague-Dawley rats were fed experimental diets containing 0.2% or sesamolin, control diet free lignans for 15 days. Compared to lignan-free diet, caused more than 1.5- 2-fold changes in the 128 40, 526 152, 516 140 genes, respectively. modified mRNA levels not only many enzymes involved fatty acid oxidation, but also proteins transportation acids into...
we present an evaluation method to qualify the embodiment caused by physical difference between master-slave surgical robots measuring activation of intraparietal sulcus in user's brain activity during robot manipulation. We show change based on optical axis-to-target view angle simulator manipulator's appearance monitor terms hand-eye coordination. The objective is explore according angle.In experiments, used a functional near-infrared spectroscopic topography (f-NIRS) imaging device...
An essential tremor (ET) is a disorder that causes involuntary oscillations. ET patients face serious difficulties in performing such daily living activities as eating, drinking, and writing. We have been developing an exoskeleton to suppress tremors support the eating movements of patients. The objective this study propose passive mechanism prevents appearance compensatory shoulder movement without using actuator. basic concept coordinate two DoF elbow joint. Two joint constrained one by...
To develop a gait rehabilitation robot for hemiplegic patients, quantitative evaluations of patient ability is needed. Patient's walk phase, which includes time balance stance and swing legs, one the most useful indexes. However, conventional methods measuring phase require laborious preparations. In this paper, novel algorithm estimating on treadmill by observing DC motor current proposed. comparison methods, it was verified that proposed had as same accuracy foot switch. Moreover, could...
We have developed a gait rehabilitation robot for hemiplegic patients using the treadmill. A walk phase, which includes time balance of stance and swing legs, is one most basic indexes to evaluate patients' gait. In addition, walking phase control our robotic system. However, conventional methods measure require another system such as foot switch force plate. this paper, an original algorithm estimate person on treadmill only current value DC motor velocity proposed. This was verified by...
In consideration of a large proportion stroke survivors with persistent deficits, current interventions have limited ability to restore normal motor function. We propose gait training system for rehabilitation hemiplegic patients convalescent stroke. It consists functional electrical stimulation (FES) device which is used influence the pattern instantly improve quality gait, and treadmill two separated belts. The stimulus triggers from FES could be controlled automatically by subject's phase...
We have been developing a new vehicle, "Tread-Walk 2", which supports walking for elderly. A control algorithm to improve the operability has constructed. As first step, we accurately estimated user's anteroposterior force from motor current value without sensor. This method is develop mechanical model that considers friction forces of treadmill and remove modeled losses output. However, need vertical in order model. Thus, proposed estimate paper describes approximate waveforms as square...
A split belt treadmill for gait rehabilitation was developed to improve the symmetry of stance phase time patients with stroke. The system, which increases affected leg and then realizes a well-balanced gait, is divided into two components. First, phases sound legs were measured presented visually in real patient physical therapist as biofeedback. Second, using biofeedback, sets different velocities belts legs. In an experiment, 11 chronic stroke participated short-term intervention trial...
Continuous, easy-to-implement, accurate inference of intended joint angles is important for effectively controlling powered prosthetic devices that can improve the lives and capabilities upper-limb amputees. Estimation difficult because conventional biosignals are not directly related to angle motion. In previous work, we began address this issue by confirming both transra-dial amputees intact subjects, measured deformation muscle bulge on skin surface change according wrist angle. This...
More and more stroke survivors are suffering from physical motor impairments. Current therapeutic interventions have various limits to the efficient recovery of normal function lower limbs. Therefore, we propose a novel gait rehabilitation system for hemiplegic patients after stroke. It integrates functional electrical stimulation (FES) with pelvis-supporting robotic system. A corresponding relationship between phase active lateral movement pelvis is first constructed experiments on...
Surgical robots have improved considerably in recent years, but their intuitive operability, and thus user interoperability, has yet to be quantitatively evaluated. Thus, we propose a method for measuring user’s brain activity while operating such robot, better enable the design of robot with operability. The objective this study was determine angle radius between an endoscope manipulator that best allows perceive as being part own body. In experiments, subject operated hand controller...
Continuum robots can produce dexterous movements and safe interactions due to their inherent compliance, but the lack of stiffness has restricted deployment in real-world environments.
