In recent years, minimally invasive surgery (MIS) has been developed in medical field. MIS is performed by inserting some tools such as forceps into holes made on a patient's body. MIS requires surgeons of skills and experiences because of the limited space to operate tools and the slight tactile sensation which the operator can feel through the forceps. To improve the performance of surgeons, this...
2-DOF haptic surgical multi drive robot is driven by multi drive linear motors, and does not separate hand function (manipulating mode) and arm function (grasping mode) of the human motion mechanically. Conventional method has one problem. When the operator want to grasp an object, he have to drive forceps open. This make operator difficult to use forceps finely and powerfully. A proposed method separates...
In this study, we achieve haptic communication between different structures. In haptic communication, tactile sensation is transmitted to a remote place by cooperating robots. Conventional haptic communication is implemented under the assumption that the masses of the actuators are equal. We have found that haptic communication system is a kind of position/force hybrid control system and that it is...
