In the paper, a low friction pneumatic cylinder and a sliding table, and both of them are embedded with aerostatic bearings are designed. A low friction pneumatic table is constructed by combining the pneumatic cylinder and the sliding table. The characteristics for the friction force versus velocity of the pneumatic cylinder and the pneumatic table are measured. Moreover, a hybrid self-tuning ...

BACKGROUND AND STUDY AIMS  Road Map (RM) fluoroscopy is a radiological technique that enables visualization of anatomic structures using image subtraction at peak opacification. RM fluoroscopy has never previously been evaluated for use in endoscopy. The aim of this study was to evaluate the usefulness of RM in guiding endoscopic intervention in the esophagus. PATIENTS AND METHODS  This was a...

The performance of the pneumatic servo systems improved greatly as the pneumatic servo valves became commercially available in the late 1980s. At present, one of the best pneumatic servo valves has a dynamic response of 100 Hz and a spool position accuracy of 2% to the full stroke. By using these pneumatic servo valves, the precise position control by the pneumatic servo system has entered a pr...

Based on flexible pneumatic bending joint and flexible pneumatic spherical joint, a kind of flexible pneumatic 5-DOF finger is proposed, which is composed of two bending joints and a spherical joint. The mathematic model of flexible pneumatic spherical joint is further analyzed. On the researching foundation of flexible pneumatic bending joint and flexible pneumatic spherical joint, the kinemat...

Development of automation and robotization in manufacturing process stimulates interest in pneumatic servo-systems whose advantages include low manufacturing costs, high dynamics and reliability (Situm et al., 2004). Unsatisfactory positioning accuracy of multiaxis pneumatic servosytems considerably reduces their application in manipulating machines, manipulators and robots. Rapid advance in pa...
