For new robot applications, as medical robots, safety has became a major concern. The human sharing the working area with the robot led to integrate the field of human factors in the development. Hence, the human component has to be integrated in the early steps of the development process. Regards to the complexity of today’s robotic application, and to the requirements of a teamwork, we choose...

Esophageal duplication cysts are infrequent anomalies of the gastrointestinal tract that are predominantly found in children. The conventional surgical approach for removal of these cysts is an open surgery one with a posterolateral thoracotomy incision. However, more recently, these cysts have been excised via video-assisted thoracoscopic surgery (VATS). In this article, we present 2 pediatric...

Unicentric Castleman's disease (UCD) is a rare disorder of unknown etiology characterized by localized lymphoid tissue proliferation and interfollicular hypervascularity. A 33-year-old Caucasian female presented with vague abdominal discomfort and pain with pressure. Ultrasound and computed tomography detected a large peripancreatic mass. Robotic-assisted resection of the mass along with en blo...

Additive manufacturing technologies are applied in different industrial fields. It is possible to produce 3D parts complex form at a lower cost with faster production capability using additive compared traditional subtractive manufacturing. Robotic welding-based wire arc (WAAM) novel technology which offers various solutions. Many products can be produced through the fields of defense, aerospac...

BACKGROUND To evaluate intraocular pressure (IOP) changes in patients undergoing robotic-assisted radical prostatectomy and to evaluate complications from increased IOP. METHODS Thirty-one eyes scheduled for robotic prostatectomy were included. Perioperative IOP measurements were performed as follows: prior to induction of anaesthesia while supine and awake (T1); immediately post-induction wh...

in this paper, the researchers have investigated a concatenated robot move (crm) sequence problem and minimal part set (mps) schedule problem with different setup times for two-machine robotic cell. they have focused on simultaneous solving of crm sequence and mps schedule problems with different loading and unloading times. they have applied a simulated annealing (sa) algorithm to provide a go...

Flapping-wing robotic insects are small, highly maneuverable flying robots inspired by biologicalinsects and useful for a wide range of tasks, including exploration, environmental monitoring, searchand rescue, and surveillance. Recently, robotic insects driven by piezoelectric actuators have achievedthe important goal of taking off with external power; however, fully autonomous operation requir...

This paper proposes a discrete-time repetitive optimal control of electrically driven robotic manipulators using an uncertainty estimator. The proposed control method can be used for performing repetitive motion, which covers many industrial applications of robotic manipulators. This kind of control law is in the class of torque-based control in which the joint torques are generated by permanen...

In this paper, we develop a new mathematical model for a cyclic multiple-part type threemachine robotic cell problem. In this robotic cell a robot is used for material handling. The objective is finding a part sequence to minimize the cycle time (i.e.; maximize the throughput) with assumption of known robot movement. The developed model is based on Petri nets and provides a new method to calcul...
