In this paper, a BCI control approach for the assistive robotic system FRIEND is presented. The objective of the robot is to assist elderly and persons with disabilities in their daily and professional life activities. FRIEND is presented here from an architectural point of view, that is, as an overall robotic device which includes many subareas of research, such as human-robot interaction, per...

Obtaining accurate percutaneous renal access when treating intrarenal disease requires substantial skill. Robotic devices have been used in a variety of surgical applications and have been successful in facilitating percutaneous puncture while improving accuracy. Laboratory models of robotic devices for percutaneous renal access have also been developed. However, several technical hurdles need ...

The aim of trajectory navigation is to position a surgical instrument along a planned trajectory. Computer assisted navigation systems show maximal flexibility but are limited by the costs and accuracy of the used optical tracking system and the human errors during free-hand navigation. Robotic devices can reach highest accuracy but are expensive and potentially safety critical due to active el...

Robot teleoperation systems have been limited in their utility due to the need for operator motion, lack of portability and limitation to singular input modalities. In this article, the design and construction of a dual-mode human–machine interface system for robot teleoperation addressing all these issues is presented. The interface is capable of directing robotic devices in response to tongue...

OBJECTIVES/HYPOTHESIS To evaluate the performance of human subjects, using a prototype robotic micromanipulator controller in a simulated, microlaryngeal operative setting. STUDY DESIGN Observational cross-sectional study. METHODS Twenty-two human subjects with varying degrees of laser experience performed CO2 laser surgical tasks within a simulated microlaryngeal operative setting using an...

OBJECTIVE Robotic procedures using the Vessel Sealer are not well reported in the literature, especially given the advantages of sealing devices already studied in standard laparoscopic procedures. This study reports our experience with the EndoWrist(®) One™ Vessel Sealer in robotic hysterectomy for myomatous uteri. STUDY DESIGN In this retrospective cohort study of the first 50 consecutive p...

The term "frameless image-guided surgery" has become as well-known to surgeons as computerized tomography or operating room microscope over the past several years. The technologies behind this new surgery option include robotic arms, infra-red camera arrays (1D and 2D), ultrasound, robotic microscopes and magnetic field digitizers. The authors have shown the magnetic field technology incorporat...

We describe a new tactile sensor for use in dexterous manipulation and telemanipulation. The sensor consists of an array of curvature-measuring elements embedded in a compliant membrane. The resulting sensor is inexpensive and robust, and can be used in robotic hands with soft fingertips for object handling and exploration. The curvature measurements provide information for manipulation plannin...

The work is designed to develop a pick and place dual arm tele robotic vehicle with a soft catching gripper that is designed to avoid extra pressure on the suspected object (Like Bombs) for safety reasons. The robotic vehicle is android application controlled for remote operation. At the transmitting end using android application device, commands are sent to the receiver to control the movement...

This paper proposes the design of a 4 DOF exoskeleton robotic arm for rehabilitation. This proposed robot arm can be used easily with either the user’s left or right arm. This robot arm is designed to have low inertia, high stiffness link, and zero backlash transmissions. It supports the patient’s arm during rehabilitation which is a repetitive task and takes a period of time. Each joint of thi...
