In this paper, a stereo vision 3D position measurement system for a three-axial pneumatic parallel mechanism robot arm is presented. The stereo vision 3D position measurement system aims to measure the 3D trajectories of the end-effector of the robot arm. To track the end-effector of the robot arm, the circle detection algorithm is used to detect the desired target and the SAD algorithm is used...

Open carpal tunnel release is one of the commonest performed procedures in hand surgery. We performed a prospective randomised control trial to compare the efficacy and patient satisfaction of the traditional arm tourniquet versus infiltration of adrenaline and local anaesthetic solution to achieve haemostasis during the procedure. Using a combination of objective and subjective measures we con...

Following a brief survey of the historic development of pneuma­ tic prostheses the actual principles of prosthetic management in bi­ lateral shoulder disarticulation or bilateral amelia are explained. The active functions are re­ stricted to active pronation and supination, active gripping of the terminal device "hook" or "hand", combined with pneumatic locking of free swinging shoulder and elb...

appearing, the wound was brought together with plaster and carbolized oil applied ; the arm being placed in a sling. On 31st May he had a sudden rush of haemorrhage in the morning, and a small traumatic aneurism was found to have formed, which under examination burst out afresh. A tourniquet being applied to brachial and chloroform at once given, Surgeon A. E. Hayes, a.m.d., proceeded to operat...

Introduction Pneumatic artificial rubber muscle (PARM) is a pneumatically driven actuator that provides mechanical effects similar in principle to those of muscle contraction. PARM is a novel actuator that has a high weight-power ratio and maximum contraction over the nominal length is 20%. As shown in Figure 1 , PARM is composed of a rubber tube impregnated with fibers. Teleoperation of pneuma...

to assess the effectiveness of ondansetron pretreatment in alleviating propofol injection pain, 135 patients were randomly assigned to one of following three groups. group 1 who received up to 2 ml pretreatment 50 mg tramadol in the saline, group 2 cases who received up to 2 ml pretreatment 4 mg ondansetron in saline, and group 3 who received up to 2 ml solution saline. a 20 gauge cannula was p...

Total knee replacement (TKR) is one of the most common surgeries over the last decade. Patients undergoing TKR are at high risk for postoperative anemia and furthermore for allogeneic blood transfusions (ABT). Complications associated with ABT including chills, rigor, fever, dyspnea, light-headedness should be early recognized in order to lead to a better prognosis. Therefore, perioperative blo...

We applied Reinforcement Learning (RL) on a real robot arm actuated by two pneumatic artificial muscles that expose a highly nonlinear behaviour. To facilitate learning, we developed an empirical model based on real robot observations. Using the learned simulation model, reinforcement learning was able to quickly learn good robot controllers.

Arteriovenous fistulas (AVF) are the preferred for hemodialysis access with suitable (2.0-2.5 mm) veins. AVF maturation has been poor globally and often leads to increased catheter contact time costs. Intermittent compression of upper arm veins may aid in forearm vein dilation pre-surgery assist placement size expectations. This is was a prospective, IRB approved trial. A novel intermittent pne...

We applied Reinforcement Learning on a real robot arm, in order to control its movements. The arm is actuated by two pneumatic artificial muscles, that expose a highly non-linear behavior. To enable a significant speed-up of the learning process, an empirical simulation is constructed, based on real robot observations. Furthermore, we introduce a learning strategy to facilitate learning. Using ...
