One important issue in a machining robotic cell is the location of the workpiece with respect to the robot. The feasibility of the task, the quality of the final work and the energy consumption, just to mention a few, are all dependent upon it. This can be formulated as an optimization problem where the objective functions are chosen in order to meet desired perf...

For the welding cell in manufacturing process of large excavation motor arm workpieces, a system framework, based on digital twin robot cell, is proposed and constructed order to optimize robotic collaboration workstation with technology. automated combined actual process, physical entity was digitally modeled 3D, operating posture beats other data were updated real time, through real-time inte...

stroke is one of the most common diseases among the elderly with high personal and societal costs. in recent years, robotic rehabilitation for stroke has become an active area of research for assistance, monitoring and qualifying the rehabilitation treatments. the key issue needed for improving rehabilitation system is that patient feedback should be taken into account by the robotic rehabilita...

PURPOSE Robotic surgery is known to provide an improved technical ability as compared to laparoscopic surgery. We aimed to compare the efficiency of surgical skills by performing the same experimental tasks using both laparoscopic and robotic systems in an attempt to determine if a robotic system has an advantage over laparoscopic system. METHODS Twenty participants without any robotic experi...

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...

Robotic workcell simulation is a modeling-based problem solving approach developed for the design, analysis, and offline programming of robotic workcells. Current industrial practices show that commercial robotic simulation software packages are able to provide designers with an interactive and virtual environment in which credible solutions for robotic workcell designs can be obtained. However...

We report on the discovery of three new pulsars in the first blind survey of the north Galactic plane (45◦ < l < 135 ; |b| < 1) with the Giant Meterwave Radio telescope (GMRT) at an intermediate frequency of 610 MHz. The timing parameters, obtained in follow up observations with the Lovell Telescope at Jodrell Bank Observatory and the GMRT, are presented.

A marsupial robotic fish system including a mother robotic fish and a daughter robotic fish is proposed. The mother robotic fish, with strong ability of movement, can transport the daughter robotic fish in its cabin. The structures of these two robotic fish are presented and fish-like motions are introduced. A dynamic light source tracking method of the daughter robotic fish is given to follow ...
