With the increasing number of people who have problems with their walking, a new type of gait rehabilitation training robot has been put forward and designed. In order to meet the requirements of the gait rehabilitation training, the whole mechanical structure and control system have been designed, and the model machine for gait rehabilitation training robot has been made. Using the human gait ...

introduction: in this experimental study, the amount of smear layer (sl) remnants in curved root canals after chemomechanical instrumentation with two engine-driven systems or hand instrumentation was evaluated. methods and materials: forty-eight mesiobuccal roots of mandibular first molars with curvatures ranging between 25 and 35 degrees (according to schneider’s method) were divided into thr...

Received Jun 24, 2013 Revised Dec 27, 2013 Accepted Jan 20, 2014 This paper focuses on the development of a reliable, low cost, average size, light weight, simple, rugged, and compact design five fingers real time smart glove and a measurement hand gripper that emulate the human hand functions that can be used as a prototype model for hand rehabilitation systems for patients suffering from para...

Current myoelectric prosthetic hands enable the user to enact a simple grasp with a strength proportional to the contraction of certain muscle groups. This paper discusses the development of a system that will allow complex grasp shapes to be identified based on natural muscle movement. The application of this system can be extended to a general device controller where input is obtained from fo...

This article reviews several tools we have developed to improve the understanding of locomotor training following spinal cord injury (SCI), with a view toward implementing locomotor training with robotic devices. We have developed (1) a small-scale robotic device that allows testing of locomotor training techniques in rodent models, (2) an instrumentation system that measures the forces and mot...

The essentially active nature of vision has long been acknowledged but has been difficult to investigate because of limitations in the available instrumentation, both for measuring eye and body movements and for presenting realistic stimuli in the context of active behavior. These limitations have been substantially reduced in recent years, opening up a wider range of contexts where experimenta...

This study proposes a LabVIEW based autonomous agricultural robot which can be used for ploughing. The control logic is designed using fuzzy logic controller to operate the robot in autonomous mode. The robot can also be controlled from a remote place using internet and its position is monitored using Global Positioning System (GPS), Data Socket protocol and Wi-Fi connection. Two DC motors are ...

PURPOSE This work provides a quantitative assessment of the positional tracking accuracy of the NDI Wave Speech Research System. METHOD Three experiments were completed: (a) static rigid-body tracking across different locations in the electromagnetic field volume, (b) dynamic rigid-body tracking across different locations within the electromagnetic field volume, and (c) human jaw-movement tra...

statement of problem: root canal cleaning and elimination of the source of infection are the most important basis and the main requirements for successful root treatment since the main cause of failure in root treatment is the permeation of bacteria or their products into the periapical tissues. nowadays, the newly designed and prcsented instruments for canal instrumentation can improve root tr...

Damage to tooth root surfaces may occur during ultrasonic cleaning with both piezoelectric and magnetostrictive ultrasonic scalers. It is unclear which mechanism causes more damage or how their mechanism of action leads to such damage. Our null hypothesis is that tooth-surface defect dimensions, resulting from instrumentation with ultrasonic scalers, are independent of whether the scaler probe ...
