Robotic-assisted esophagectomy has been introduced as a minimally invasive esophagectomy; however, transhiatal esophagectomy with extended lymphadenectomy in the middle retromediastinal field has never been reported so far. We have developed a totally transhiatal robotic manipulation which enables middle retromediastinal lymph dissection. With this method, transthoracic approach, which is assoc...

In this project, a tele-operated anthropomorphic robotic arm and hand is designed and built as a versatile robotic arm system. The robot has the ability to manipulate objects such as pick and place operations. It is also able to function by itself, in standalone mode. Firstly, the robotic arm is built in order to interface with a personal computer via a serial servo controller circuit board. Th...

Acknowledgments First of all, I wish to thank my advisor Armin B. Cremers for his guidance, encouragement, and patience. I thank Wolfram Burgard for his willingness to be the co-referent. I am grateful to both of them for offering me the opportunity to work on the Robotic Tele-Presence Lab (RTL) Project, a part of KI-NRW/Virtual Knowledge Factory, headed by Armin B. Cremers and Wolfram Burgard,...

PURPOSE We sought to evaluate the feasibility and safety of open or robotic radical prostatectomy (RP) after rectum, sigmoid, or colon surgery. MATERIALS AND METHODS Sixty-four patients with a median age of 65 years (range, 46-73 years) who underwent RP after previous pelvic surgery were included. Twenty-four patients (38%) underwent robotic RP and 40 patients (62%) underwent open RP. Bilater...

We propose a semi-autonomous teleoperation framework, developed in (Lee & Spong 2005), as a means for robotic missions to establish infrastructure and preparations for the sustained presence of humans on the Moon. This semiautonomous framework consists of the two control loops: 1) local autonomous control and interagent communication on the Moon ensure secure cooperative manipulation of objects...

In the bilateral hydraulic servo control system of a construction tele-robot with in-situ force sensing, the p-f type force feedback architecture is liable to result in an impact on the operator hand, and its high amplitude will cause the control unstable. In order to solve this problem an improved force feedback control method with the feature of a T-S fuzzy feedback coefficient, which could b...

One of the main reasons for the development of space manipulators is to replace astronauts to perform tasks that involving long, repetitive operations and unhealthy, hazardous environment. Due to the particular harsh environment of space and the increasing demands of satellite maintenance, on-orbit refueling and assembly etc., the application of space robot has received significant attention. S...

OBJECTIVE To describe the management of bilateral oral ranulas with the use of the da Vinci Si Surgical System and discuss advantages and disadvantages over traditional transoral resection. STUDY DESIGN Case Report and Review of Literature. RESULTS A 47 year old woman presented to our service with an obvious right floor of mouth swelling. Clinical evaluation and computerized tomography scan...
