The Iterative Closest Point (ICP) algorithm is currently one of the most popular methods for rigid registration so that it has become the standard in the Robotics and Computer Vision communities. Many applications take advantage of it to align 2D/3D surfaces due to its popularity and simplicity. Nevertheless, some of its phases present a high computational cost thus rendering impossible some of its applications. In this work, it is proposed an efficient approach for the matching phase of the Iterative Closest Point algorithm...

PURPOSE: This work presents the mechanical design of 4 configurations of compliant fingers in order to address the need for commercially feasible prosthetic and robotic hands. METHODS: The fingers consist of a single part and utilize a compliant mechanism to reduce the cost and control complexity. The geometric parameters of the compliant finger designs follow the Fibonacci series. The first and second compliant fingers have 2 joints and 2 degrees of freedom. The others have 3 joints and 3 degrees of freedom...

Over the last decade there has been a resurgence in the use of plant protoplasts that range from model species to crop species, for analysis of signal transduction pathways, transcriptional regulatory networks, gene expression, genome-editing, and gene-silencing. Furthermore, significant progress has been made in the regeneration of plants from protoplasts, which has generated even more interest in the use of these systems for plant genomics. In this work, a protocol has been developed for automation of protoplast isolation and transformation from a 'Bright Yellow' 2 (BY-2) tobacco suspension culture using a robotic platform...

This paper addresses a fundamental question in folk metaphysics: how do we ordinarily view human agency? According to the transcendence account, we view human agency as standing outside of the causal order and imbued with exceptional powers. According to a naturalistic account, we view human agency as subject to the same physical laws as other objects and completely open to scientific investigation. According to exceptionalist naturalism, the truth lies somewhere in between: we view human agency as fitting broadly within the causal order while still being exceptional in important respects...

PURPOSE: Urinary biomarkers of renal injury urinary may identify loss of renal function following nephron-sparing surgery (NSS). This study was designed to evaluate whether urinary l-type fatty acid-binding protein (l-FABP) is an early biomarker of loss of renal function after NSS. Specifically, the kinetics of urinary l-FABP level after NSS and its correlation with factors related to ischemic renal injury were analyzed. METHODS: This study prospectively evaluated 18 patients who underwent NSS between July and December 2014, including 12 who underwent laparoscopic and six who underwent robot-assisted partial nephrectomy...

The highly efficient and agile water-surface locomotion of water striders has attracted substantial research attention. Compared with imitating the horizontal rowing motion, imitating the jumping capability of water striders is much more challenging because the strong interaction in the jumping process easily causes the robot to sink. This study focuses on designing a miniature robot capable of continuously jumping on the water surface. A spring-based actuating mechanism is proposed to produce a large jumping force...

BACKGROUND: This study aimed to compare perioperative outcomes of patients undergoing robotic, laparoscopic, and open colectomy using a procedure-targeted database. METHODS: Retrospective review of patients undergoing elective colectomy in 2013 was conducted using the procedure-targeted database of the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP). Robotic, laparoscopic, and open groups were matched (1:1:1) based on age, gender, body mass index, surgical procedure, diagnosis and ASA classification...

BACKGROUND: Transoral robotic surgery (TORS) is now a well-validated technique for resection of head and neck cancers. Benefits include reduced patient morbidity, swallowing preservation and rationalization of adjuvant therapies. METHODS: This was a single-centre, retrospective review of 35 patients who underwent TORS of oro-, retro- and parapharyngeal tumours between March 2014 and August 2015. Outcome measures included resection margins, swallowing function and impact on post-operative radiotherapy...

The objective of this study is to determine the cost and charge differences between patients undergoing open vs. robotic pyeloplasty. This is a retrospective analysis of the Pediatric Health Information System (PHIS) database in patients undergoing pyeloplasty between 2004 and 2013 conducted in large pediatric children's hospitals in the United States which contribute to PHIS. The participants included all pediatric patients undergoing pyeloplasty at these institutions. We assessed RCC-based cost, charge details, length of stay, and the presence of complications, and compared them between open and robotic cases...

INTRODUCTION AND HYPOTHESIS: There has been a trend toward robotic sacrocolpopexy in the United States despite longer operating times and higher costs compared with traditional laparoscopy. The current study objective was to evaluate incision to closure times of laparoscopic sacrocolpopexy in a urogynecologic practice with extensive experience in the laparoscopic approach for pelvic reconstruction. METHODS: We conducted a single-center retrospective evaluation of consecutive patients undergoing laparoscopic sacrocolpopexy for vaginal vault prolapse using a permanent polypropylene Y-mesh over a 1-year period...

Growth in human populations causes habitat degradation for other species, which is usually gauged by physical changes to landscapes. Corresponding habitat degradation to air and water is also common, but its effects on individuals can be difficult to detect until they result in the decline or disappearance of populations. More proactive measures of pollution usually combine abiotic samples of soil, water or air with invasive sampling of expendable species, but this approach sometimes creates ethical dilemmas and has limited application for threatened species...

Delayed sequelae following conservative management of renal trauma in the pediatric population are uncommon. Reports of delayed operations to manage these sequelae are even less common. Here we present the case of a 16-year-old male patient who had delayed development of upper urinary tract obstruction with recurrent infections following high-grade renal trauma managed conservatively. Ultimately he required a robotic-assisted partial nephrectomy two years after initial non-operative management. This is unique as no prior studies to our knowledge have described delayed hydronephrosis and delayed partial nephrectomy over a year following renal trauma...

Because of the remarkable developments in robotics in recent years, technological convergence has been active in this area. We focused on finding patterns of convergence within robot technology using network analysis of patents in both the USPTO and KIPO. To identify the variables that affect convergence, we used quadratic assignment procedures (QAP). From our analysis, we observed the patent network ecology related to convergence and found technologies that have great potential to converge with other robotics technologies...

PURPOSE OF REVIEW: Although open ureteral reimplantation remains the gold standard for surgical correction of vesicoureteral reflux (VUR), robotic-assisted laparoscopic ureteral reimplantation (RALUR) holds promise and is becoming more widely utilized. The present article outlines primary operative techniques for RALUR, summarizes the current literature with respect to surgical outcomes and costs, and discusses early applications of RALUR to complex and reoperative cases. RECENT FINDINGS: Intravesical and extravesical techniques for RALUR have been described...

Visual odometry estimates the ego-motion of an agent (e.g., vehicle and robot) using image information and is a key component for autonomous vehicles and robotics. This paper proposes a robust and precise method for estimating the 6-DoF ego-motion, using a stereo rig with optical flow analysis. An objective function fitted with a set of feature points is created by establishing the mathematical relationship between optical flow, depth and camera ego-motion parameters through the camera's 3-dimensional motion and planar imaging model...
