Laparo-Endoscopic Single Site (LESS) Robotics Surgery is an advanced technology in the field of Minimally Invasive Surgery (MIS). The LESS surgical robots significantly improve the surgeon’s accuracy, dexterity and visualization, and reduce the invasiveness of surgical procedure results in faster recovery time and improved cosmetic results. In a standard robotic endosurgery, the palpation of tissues is performed by laparoscopic graspers located at the end effectors. The master-slave configuration in robotic surgery leads in remote access to the operation site. Therefore, surgeon’s ability to perceive valuable sensory information is severely diminished. Sensory information such as haptics, which is essential for safe …

Various studies aim to understand the fundamentals of kicking, primarily the instep kick commonly used by soccer players. Of those studies, most are limited to a 2D analysis using high-speed cameras for position tracking and electromyography to observe muscle activity. The few studies that investigate a 3D model are limited in their position tracking capabilities and focus mainly on joint flexion potentials and foot speed. To the authors knowledge no study of this caliber has been performed on the kinematics and dynamics of place kicking in American football. This thesis uses a 12 camera high-speed motion tracking system to investigate …
