Abstract: This paper deals with the calculation of the angles of rotation of the robots elements. Determination of the position of the gripping device orientation occurs when it touch the working object. The position of working object will determine and rotation of the manipulator elements that must perform database actions.

Abstract: The study of the best conditions to accomplish the robotic assembling imposes the determination of the restrictions imposed by the characteristics of the desired assembling. To analyze the requirements imposed to the assembling robot in this paper there have been considered Petri Graphs with dynamic markings. These schemes allow a synthetic representation of the assembling process and they praise clearly the active phases of the robot.

Abstract: To achieve high efficiency in a robotic manufacturing system, an optimized layout arrangement and material flow path design are important due to the large percentage of product cost that is related to material handling, equipment positioning, material flow path, and products variety and volume (flexibility). Facility layout problem (FLP) can be considered as a multi-criteria problem due to presence of the qualitative criteria such as flexibility and the quantitative criteria for instance total cost of handling material. In this paper, we combined a well-known facility layout algorithm (CRAFT) with Analytic Hierarchy Process (AHP) technique and decision matrix method to facilitate a multi criteria evaluation. The proposed approach aims to incorporate qualitative criteria in addition to quantitative criteria for evaluating facility layout patterns. A case study on a robotic system for manufacturing plate type oil coolers reveals the effectiveness of the proposed approach.

Abstract: In this paper are presented aspects concerning new method of winding carbon wire to obtain composite structure using two cooperative industrial robots. The goal of this study is to use two robots working together for creating only one part obtaining faster cycle time like manual method. For this are proposed some collaboration methods between robots and different methods of trajectory plan. First proposed obstacle is when the position of the robots between them is unknown. For this is proposed a calibration algorithm for robot positions. The collaboration must be very fast. For this the proposal is to use direct communication between robots using digital inputs and outputs. For trajectory planning is involve the virtual space for designing and testing the trajectory and then transpose the results in real robots controller.

Abstract: The integrated system concept involves the development of the mechanization and automatization of the handling, transfer storage and assembly operations in process at the same level with the actual processing operations. For safe handling and to not introduce errors during a trial robot technology, the movement of the object to be manipulated and controlled before both gripper and attached equipment manufacturing plant so that the position of technology and technology base gripping be a unique link. The paper analyzed a device sensing and motion control in robotic technology systems and the technological equipment and targets the complex phenomenon of sliding (moving object manipulated during the technological process)

Abstract: In this paper we have presented a method to solve the inverse kinematics problem of a redundant robotic arm with seven degrees of freedom and a human like workspace based on mathematical equations, Fuzzy Logic implementation and Simulink models. For better visualization of the kinematics simulation a CAD model that mimics the real robotic arm was created into SolidWorks® and then the CAD parts were converted into SimMechanics model.

Abstract: Serial industrial robots are able to perform point to point movements with a great degree of accuracy and flexibility. Thus, they are mostly used for welding, painting and pick-and-place task. Manufacturing processes require the control of movements on the entire path, so industrial robots are seldom used for this kind of task. The paper presents a research about using industrial robots for manufacturing prosthetic devices. The approach was to build a kinematic model of the robot and to implement it in a commercially available CAM program and to design and manufacture a milling unit as the end-effecter of the robot.
