In this paper, motion-reproduction system for picking by multiple-DoFs manipulator with a stereo camera is proposed. The conventional motion-reproduction is able to pick different sized objects because of considering force in the control system. However, the conventional system has difficulty in picking the positional changed objects in motion-reproduction. The proposed method compensates the positional...
Image navigation systems and robotics are leading technologies to improve the accuracy of dental surgery. In this paper, stereo vision based navigation system is implemented to the three degrees of freedom implant surgery assistant robot. The aim of this research is to achieve cooperative guide system for teaching the information of “where to start cutting”. To achieve this aim, modulated potential...
Advancement of the technology in the modern world facilitate for the development of many human supported machines such as robots. These machines use different kinds of mechanical structures and electrical dive systems with the use of proper controllers to achieve the desired task. However most of these robots need to be miniaturized although it is constrained due to various problems such as the actuator...
Robots are taken attention as one of key solutions for nursing care field along with aging of population. In the nursing care field, the robots have to work in the limited space and contact with humans directly. Therefore miniaturization and precise force control are two important issues for nursing care robots. Then a tendon-driven rotary actuator with thrust wires and a polyethylene (PE) line was...
In the future, robots will be important device widely in our daily lives to achieve complicated tasks. To achieve the tasks, there are some demands for the robots. In this paper, two strong demands of them are taken attention. First one is multiple-degrees of freedom (DOF), and the second one is miniaturization of the robots. Although rotary actuators is necessary to get multiple-DOF, miniaturization...
The use of robotic devices in surgical applications has been growing in recent years. Surgical robots are beginning to find applications in minimally invasive surgeries. The control issues pertaining to many of the applications of robotics to surgery are similar. In all cases, the ability to accommodate unique special-purpose mechanical designs is important, as is the ability to restrict the motions...
