Industrialists interested automates their factories to increase production, reduce costs and improve quality by using robots in leadership and finishing most of the production processes, where robots characterized as mechanical structures programmable to perform tasks accurate, speed and reliability. Research depend in concluding the optimal path on generating virtual paths (triangular, curved, square) reflects the robotic arm movement to reach the target point, where as it has been known moving time and angles of rotation and torque in the joints under the influence of gravity through the study of horizontal and vertical movement of the robotic arm. A study of suggested trajectories for the robotic arm shows that the best paths on the safety of robotic arm motors is semi-circular path as limiting the occurrence of mechanical shocks or the appearance of high values of the joints torques. while showing that the path that achieves less time to reach the target point and less amount of energy is the triangular path in the case of horizontal motion of the robotic arm despite the emergence of sharp deviations in the torque and power schemas as a result of the sudden change in the direction of movement. The negative impact of gravity is especially apparent when the second joint up or down movement, causing the appearance of peaks in energy curve reflects the high values of determination in this joint.

Most robotic industries depend on using (servo motors) and (stepper motors) orcontinuous current motors (DC motors) for movement transition, which increases the cost and complicates the robot’s controlling process, as well as its driving circuits. This essay deals with using pneumatic in the new design and building of a robot’s arm, that can manage to do many tasks with a much lower budget than the one needed for any of the above mentioned methods, that’s because it can be used for tasks that need high speed and capacity, but don’t need precision.
We describe work in progress for training a humanoid robot to produce iconic arm and head gestures as part of task-oriented dialogue interaction. This involves the development and use of a multimodal dialog manager for non-experts to quickly program' the robot through speech and vision. Using this dialog manager, videos of gesture demonstrations are collected. Motor positions are extracted from these videos to specify motor trajectories where collections of motor trajectories are used to produce robot gestures following a Gaussian mixtures approach. Concluding discussion considers how learned representations may be used for gesture recognition by the robot, and how the framework may mature into a system to address language grounding and semantic representation.
Motion Planning is an important and potential issue in Robotics, because it gives the robot the ability to reach its target automatically with collision free, which increase the robot performance and reduce its operational cost. The robot motion pl anning is commonly divide into two approaches: finding the appropriate path and making the robot tracking this path until it reaches its goal. This research depends on one of the most common obstacles avoidance path planningtechniques (Bug algorithms) to find global path of robot. And make the Boe-Bot robot (differential drive robot) tracking the paths generated by these algorithms in a certain environment.
Robot navigation is challenging for building intelligence mobile robots. To find Proper possible path from starting point to target point, that reduces time and distance, avoiding collision with obstacles is a current potential research area. Rapid ly exploring random trees (RRTs)is considered as one of the fastest methods to find solutions. Moreover, this algorithm is computationally efficient; therefore, it can be used in multidimensional environments. This paper reviews the RRT algorithm, and provides application of path planning to differential robot in two different workspaces using Virtual Robot Experimentation Platform) V-REP(simulator. This research clarifies the algorithm’s ability to find suitable path in relatively short time, and demonstrated the ability of V-rep to model and 3D simulate of mobile robot’s movement efficiently and smoothly.
In this paper, we introduce an Effective algorithm to find the shortest path in Multiple – Source Graph, by choosing the path between the source and the distance that gives at least the length of the path down to the sink. This algorithm is based on the principle of iteration to access the optimal solution of the shortest-path problem, Where the algorithm steps are repeated for all the darts in the Graph. We proved that the time of implementation of the proposed algorithm in this paper is linear time O(n+L) and This is considered the best times of the algorithms at all.
