摘要:Abstract(#br)Electro-hydrostatic actuators (EHAs) possess excellent power/weight ratio and space-saving properties. However, uncertainty exists with respect to the presence of non-linear behaviors and dynamic characteristics. Servo pumps, hydraulic motors, and oil-filled pipes ca...

摘要:Abstract(#br)Hydraulic actuators have high power-to-weight ratios, making them suitable for high-power robotic applications such as in walking robots and construction machines. However, large frictional forces in hydraulic actuators, rotary hydraulic actuators in particular, degr...

摘要:SUMMARY(#br)This paper describes an estimation method for the physical parameters of human arms. The parameters are used in the medical and kinematic analysis fields. Personal differences are important, but some of the conventional methods do not consider personal difference...

摘要:SUMMARY(#br)Working in extreme environments (e.g., at disaster sites) is dangerous for humans. Hence, it is important to use teleoperated robots in such extreme environments. Because heavy lifting work is involved, hydraulic actuators with high output are more commonly used than ...

摘要:Abstract(#br)Hydraulic actuators have good power/weight ratio, and electro-hydrostatic actuators (EHAs), which is a way to control oil flow, are recently keeping attention. EHAs are directly driven by servomotors resulting in high power efficiency, low cost, and small systems. Ho...

摘要:Abstract(#br)In this paper, a force‐based disturbance observer (DOB) and a force control system using the DOB are proposed to obtain dynamic force control under disturbances. A DOB can reduce the effect of disturbances and modeling errors on robots. In a conventional DOB, an...

摘要:The purpose of this study is to compensate for the hysteresis in a six-axis force sensor using signal processing, thereby achieving high-precision force sensing. Although mathematical models of hysteresis exist, many of these are one-axis models and the modeling is difficult if t...

摘要:Abstract(#br)A force/torque sensor is a useful tool for detecting an external force acting on a robot. Techniques to detect a contact position from a single force/torque sensor have also been developed, but these have used rigid materials in the contact areas. In terms of safety,...
