The inherent dynamics of the master manipulator of a teleoperated robot-assisted surgery (RAS) system can affect the movements of a human operator, in comparison with free-space movements. To measure the effects of these dynamics on operators with differing levels of surgical expertise, a da Vinci Si system was instrumented with a custom surgeon grip fixture and magnetic pose trackers. We compared users' performance of canonical motor control movements during tele-operation with the manipulator and freehand cursor control, and found significant differences in several aspects of motion, including target acquisition error, movement speed, and acceleration. In addition, there was preliminary evidence for differences between experts and novices. These findings could impact robot design, control, and training methods for RAS.

For diverse applications in optical, electronic and consumer industries, the use of glass and glass ceramics as substrates for functional coatings is becoming of outstanding interest in order to develop advanced composites. Atmospheric Plasma Spraying (APS) is an adequate technology for the deposition of a wide variety of materials on glasses. Glass and glass ceramics are characterised by their specific thermo physical properties like low or even negative CTE, low heat conductivity and high dimensional stability. Consequently, modified production processes in comparison to the established coating operations on metal surfaces are required regarding the substrate activation methods or a more accurate heat transfer guidance to the substrate by optimized robot trajectories. This paper aims to give an overview of the investigations carried out at the IMTCCC for the development of plasma sprayed layer composites on borosilicate glass and glass ceramic substrates.

The world shipbuilding industry since the beginning of the last century with flux cored wire material.Since the flux cored wire material use welding materials has developed into a more efficient submerged arc welding consumables and gas shielded welding welding consumables and can be more easily combined with automated welding and robot welding.So far,flux cored material applications favored.Gas shielded arc welding consumables mainly divided solid wire and flux cored wire,flux cored wire applications has increased year by year because of its practicality and efficiency.Flux cored wire as the main welding consumables trends,especially in the thick carbon steel plate welded favored.In order to understand the nature of the thick-walled components weld cracking and produces original Due on a thick-wailed T-joints butt weld ultrasonic flaw found Two crack metallographic and SEM fracture analysis.

The Ukrainian medical device market is expected to grow by a CAGR of 1.5% over the 2013-2018 period, a large fall compared with previous forecasts, caused by poor economic performance that has resulted from increasing political tensions with Russia. Demand for expensive medical equipment is largely met by imports, although the domestic industry is gradually accounting for a larger share. Diagnostic imaging exports have increased by five times since 2005, and they accounted for over 30% of total exports in 2013.

The Glove-Enabled Computer Operations (GECO) system enables an extravehicular activity (EVA) glove to be dual-purposed as a human-computer interface device. This paper describes the design and human participant testing of a right-handed GECO glove in a pressurized glove box. As part of an investigation into the usability of the GECO system for EVA data entry, twenty participants were asked to complete activities including (1) a Simon Says Games in which they attempted to duplicate random sequences of targeted finger strikes and (2) a Text Entry activity in which they used the GECO glove to enter target phrases in two different virtual keyboard modes. In a within-subjects design, both activities were performed both with and without vibrotactile feedback. Participants mean accuracies in correctly generating finger strikes with the pressurized glove were surprisingly high, both with and without the benefit of tactile feedback. Five of the subjects achieved mean accuracies exceeding 99 in both conditions. In Text Entry, tactile feedback provided a statistically significant performance benefit, quantified by characters entered per minute, as well as reduction in error rate. Secondary analyses of responses to a NASA Task Loader Index (TLX) subjective workload assessments reveal a benefit for tactile feedback in GECO glove use for data entry. This first-ever investigation of employment of a pressurized EVA glove for human-computer interface opens up a wide range of future applications, including text chat communications, manipulation of procedureschecklists, cataloguingannotating images, scientific note taking, human-robot interaction, and control of suit andor other EVA systems.

Although France continues to rank among the top five largest medical device markets in the world, growth rates are modest by global standards. The continuing drive to hold down costs and the more restrictive measures being implemented to regulate medical device expenditure in a similar manner to drug expenditure will continue to constrain spending on medical devices.

Two-wheeled self-balanced robot based on the inverted pendulum model belongs to the category of the wheeled robots and it shares many characters with inverted pendulum,which are nonlinear,strong coupling,multi-variable and parameter uncertainty.Because there are many methods to keep this unstable robot self-balanced,this kind of robot has become an ideal platform to verify various kinds of control theories.In this paper,the two-wheeled robot is built on LEGO NXT set and depends on the sensors like gyro,angle transducer to keep upright.The mathematic and kinetic model of the robot is established according to the Lagrangian Dynamics and state-space equation of the whole system is presented.At last,a kind of state feedback control with the state observer is set up to make the system closed and stable.

Dexterous robotic hands are changing the way robots and humans interact and use common tools. Unfortunately, the complexity of the joints and actuations drive up the manufacturing cost. Some cutting edge and commercially available rapid prototyping machines now have the ability to print multiple materials and even combine these materials in the same job. A 3D model of a robotic hand was designed using Creo Parametric 2.0. Combining "hard" and "soft" materials, the model was printed on the Object Connex350 3D printer with the purpose of resembling as much as possible the human appearance and mobility of a real hand while needing no assembly. After printing the prototype, strings where installed as actuators to test mobility. Based on printing materials, the manufacturing cost of the hand was $167, significantly lower than other robotic hands without the actuators since they have more complex assembly processes.
