Development of intuitive user interface of a dexterous forceps with wrist joint for minimally-invasive surgery (MIS) is important for reducing the surgeon's confusion and fatigue. In this paper, a wearable robotic forceps manipulator is proposed. By measuring the wrist attitude of the surgeon by a motion sensor and driving the forceps tip by actuators, intuitive operation is realized, compared with...
In aging societies, there is a strong demand for robotics to tackle problems caused by the aging population. Patient transfer, such as lifting and moving a bedridden patient from a bed to a wheelchair and back, is one of the most physically challenging tasks in nursing care, the burden of which should be reduced by the introduction of robot technologies. We have developed a new prototype robot named...
Transapical aortic valve replacement under MRI guidance in a beating heart is a recent minimally invasive technique that could benefit from a surgical assistant system. We present a robotic surgical assistant system that can precisely and repeatably deliver aortic valve prostheses. The surgical system consists of an imaging system, an Innomotion robotic arm, a 3-DoF valve delivery module and user...
This paper presents the development of new prismatic actuation approach and its application in human-safe humanoid head design. To reduce actuator output impedance and mitigate unexpected external shock, the prismatic actuation method uses cables to drive a piston with preloaded spring. By leveraging the advantages of parallel manipulator and cable-driven mechanism, the developed neck has a parallel...
It is well known that the massage therapy is useful for the rehabilitation of various diseases (i.e. oral health problems, etc.). Although various apparatus have been developed for the massage of the torso and limbs, there is still little knowledge about their real effectiveness. For this purpose, authors have proposed the development of a robotic system that provides massage therapy of the maxillofacial...
In typical teleoperated surgeries, skilled staff are still necessary in the remote surgical room to change manipulator tooling and to manage surgical supply delivery and removal. This paper describes the development of a nurse robot to provide automated support to a teleoperated surgical manipulator system in environments where the presence of skilled surgical support staff may not be practical. The...
This paper discusses the extension of sample-based planning methods to the application of sensor planning for a partially unknown, moving target. This is achieved by modeling the target as a time-varying stochastic process with known mean and variance. Using the unscented transform, the target's statistics are then propagated through a user-supplied sensing effectiveness metric. The planner is demonstrated...
This paper describes a multi-joint robot finger with soft compliant mechanism for safe and comfortable nursing-care services. In proposed mechanism, we utilize 2 different types of elastic elements at fingertip and MP joint (Metacarpa-Phalangeal Joint), respectively, so as to realize soft and stable contact with human body. At fingertip, a hemisphere shaped silicone gum cushion is mounted, while eight...
