Active and Passive Range Sensing for Robotics

Integration of active and passive sensing techniques for representing three-dimensional objects

Optimization of Ankle-Foot Prosthesis with Active Alignment by Passive Elements

Today, often ankle’s active prosthesis is used for transtibial amputated people’s walking, because these prostheses have some advantages such as increasing power and decreasing metabolism. In most of active prosthesis in order to create a movement or increase the force at the push-off, electrical actuators are used like a motor. In cases where a higher-power motor is necessary, the capacity, we...

Acquisition and interpretation of 3-D sensor data from touch

Acquisition of 3-D scene information has focused on either passive 2-D imaging methods (stereopsis. structure from motion etc.) or 3-D range sensing methods (structured lighting, laser scarming etc.). Little work. has been done in using active touch sensing with a multi-fingered robotic hand to acquire scene descriptions. even though it is a well developed human capability. Touch sensing differ...

Comparison of Post Operative Early Active and Passive Mobilization of Flexor Tendon in Zone 2

Objectives: Despite numerous studies, having the best outcome is challenging after flexor tendon repairs in zone 2. This study were done to test the hypothesis that immediate postoperative active mobilization will achieve similar outcomes to passive mobilization. Methods: Fifty fingers in 38 patients with flexor tendon repair in zone 2 were enrolled in this trial. The patients randomly assig...

بررسی حس عمقی در مفصل زانوی بیماران مبتلا به استئوآرتریت اولیه زانو

Knee is a common site of osteoarthritis possibly because it is often subject to trauma. Primary knee osteoarthritis has no known etiology while secondary osteoarthritis can be traced to abnormal joint mechanics. Actually, osteoarthritis may be a physiologic response to repetitive, longitudinal impulse loading of the joint. Knee proprioception derives from the integration of afferent s...
