In this study, a wearable sensor system was developed to measure finger motions, which consisted of soft and stretchable silicone filled with the electro-conductive liquid metal, called eutectic Gallium Indium (EGaIn) alloy. Due to the light weight and highly stretchable properties of the silicone, the wearable sensor system allowed natural movements for the users, and it was able to adapt various...
To develop a mechanism that will smoothly support the standup motion of elderly people, we reconsidered the operation-start timing of our previously developed device using a measurement apparatus. In the experiments with elderly subjects, the mechanism did not work as well as it did with younger subjects. For younger subjects, the floor's reaction force decreased when the support mechanism was used,...
The final goal of our research is to develop a rehabilitation support robot for self-standing-up training of hemiplegic stroke patients to restore normal standing-up motion. To improve the motor function of the patient's paralyzed leg, a guided standing-up training is effective. The therapist controls the patient's left/right load balance by pulling or pushing the patient's waist during standing-up...
The Doppler-Bearing Target Motion Analysis (DBTMA) problem arises in various military applications related to target tracking. The DBTMA problem is to estimate the position and velocity of a target using both frequency and bearing measurements. As the method to increase the estimation accuracy in the DBTMA problem, this paper introduces observer motion controls under the following motion constraints:...
In this paper, the design of a hand rehabilitation system is introduced for evaluating the hand function and performing the hand rehabilitation. In an attempt to evaluate the hand function such as a finger stiffness, a finger independency, a multi-finger synergy quantitatively, the finger joint angles and the external force to the finger should be measured via the device. In addition, the device assists...
