“…Its solution, however, is much more complex than direct kinematics since there is no unique analytical solution. Each manipulator needs a particular method considering the system structure and restrictions [10]. In the inverse kinematics the user specifies the desired goal position of the end-effector in cartesian space as (x, y, z) where z is the height of the end effector From figure (4) θ 1 can be calculated from the following equation θ 1 = atan2 (py,px).…”

This work proposes a close form solution algorithm to solve the inverse kinematics for a five degree of freedom (DOF) robot manipulator, close form solution is preferable to numerical solutions because analytical ones yield complete solutions and are computationally fast and reliable. The motion path of a robot arm is calculated using the geometric analysis. The proposed algorithm is verified using developed simulation modules. Computer simulation is conducted to demonstrate accuracy of the proposed algorithm to generate an appropriate joint angle for reaching desired Cartesian coordinate. The algorithm has been tested yield fair, which have also compared with the robot arm's actual reading.

“…Robot arm kinematics explain the analytical description of the motion geometry of the manipulator with the reference to a robot coordinate system fixed to a frame without the consideration of the forces or the moments causing the movements. [8] For the direct kinematics the inputs are the joint angle vectors and the link length parameters, while the output of the problem is the orientation and the position of the tool or gripper. The block diagram representation of the direct kinematics shown by Many methods can be used in the direct kinematics calculation.…”

“…These four parameters are called Denavit-Hartenberg (D-H) parameters. The D-H representation provides a systematic method for describing the relationship between adjacent links and gives a mathematical description for all serial manipulators depending on the robot geometry [5], [8], [9]. It defines the position and orientation of the current link with respect to previous one.…”

This paper present a direct kinematics modeling of 5 DOF stationary articulated robot arm which is used for educational tasks, and presents an adopted modeling method to represent and simulate the simultaneous positional coordinates for each joint of the robot while it moving from one target to another, where a Lab Volt R5150 robot arm has been taken as a case study. the Denavite -Hartenberg (D-H) model of representation is used to model robot links and joints in this paper. It utilizes Matlab 2010a software as the tools for manipulation and testing. The adopted modeling solution was found to be identical with the physical behaviors.

“…In [37], designed a system of controlled Robotic arm on wheelchair containing 7-DOF arm with 2-DOF control of wheelchair for the disabled people. In paper [38], using AutoCAD and MATLAB as testing tools, Kinematics, path planning, and Jacobian velocities were evaluated in an AL5B Educational Robot. This study [39] combined two distinct approaches that are axis-invariant and dual quaternions for the location and orientation of the endeffector with the least amount of error to simulate the inverse kinematics for the 6 DOF manipulator.…”

In disaster areas, robot manipulators are used to rescue and clearance of sites. Because of the damaged area, they encounter disturbances like obstacles, and limited workspace to explore the area and to achieve the location of the victims. Increasing the degrees of freedom is required to boost the adaptability of manipulators to avoid disturbances, and to obtain the fast desired position and precise movements of the end-effector. These robot manipulators offer a reliable way to handle the barrier challenges since they can search in places that humans can't reach. In this research paper, the 9-DOF robotic manipulator is designed, and an analytical model is developed to examine the system’s behavior in different scenarios. The kinematic and dynamic representation of the proposed model is analyzed to obtain the translation or rotation, and joint torques to achieve the expected position, velocity, and acceleration respectively. The number of degrees may be raised to avoid disturbances, and to obtain the fast desired position and precise movements of the end-effector. The simulation of developed models is performed to ensure the adaptable movement of the manipulators working in distinct configurations and controlling their motion thoroughly and effectively. In the proposed configuration the joints can easily be moved to achieve the desired position of the end-effector and the results are satisfactory. The simulation results show that the redundant manipulator achieves the victim location with various configurations of the manipulator. Results reveal the effectiveness and efficacy of the proposed system.
