A fuzzy logic controllerfora two link functional manipulatorIJCNCJournal
This paper presents a new approach for designing a Fuzzy Logic Controller "FLC"for a dynamically multivariable nonlinear coupling system. The conventional controller with constant gains for different operating points may not be sufficient to guarantee satisfactory performance for Robot manipulator. The Fuzzy Logic Controller utilizes the error and the change of error as fuzzy linguistic inputs to regulate the system performance. The proposed controller have been developed to simulate the dynamic behavior of A
Two-Link Functional Manipulator. The new controller uses only the available information of the input-output for controlling the position and velocity of the robot axes of the motion of the end effectors

FORWARD KINEMATIC ANALYSIS OF A ROBOTIC MANIPULATOR WITH TRIANGULAR PRISM STR...IAEME Publication
To control robot manipulators as per the requirement, it is important to consider its kinematic model. In robotics, we use the kinematic relations of manipulators to set up the fundamental equations for dynamics and control. The objective of this paper is to introduce triangular prism structured manipulator and derive the forward kinematic model using Denavit-Hartenberg representation.
Pick and place task is one among the most important tasks in industrial field handled by “Selective
Compliance Assembly Robot Arm” (SCARA). Repeatability with high-speed movement in horizontal plane is
remarkable feature of this type of manipulator. The challenge of design SCARA is the difficulty of achieving
stability of high-speed movement with long length of links. Shorter links arm can move more stable. This
condition made the links should be considered restrict then followed by restriction of operation area
(workspace). In this research, authors demonstrated on expanding SCARA robot’s workspace in horizontal area
via linear sliding actuator that embedded to base link of the robot arm. With one additional prismatic joint the
previous robot manipulator with 3 degree of freedom (3-DOF), 2 revolute joints and 1 prismatic joint is become
4-DOF PRRP manipulator. This designation increased workspace of robot from 0.5698m2 performed by the
previous arm (without linear actuator) to 1.1281m2 by the propose arm (with linear actuator). The increasing
rate was about 97.97% of workspace with the same links length. The result of experimentation also indicated
that the operation time spent to reach object position was also reduced.
Large Convolutional Network models have

Mechanism Design and Kinematics Analysis of Display Bracket Based on AdamsIJRESJOURNAL
ABSTRACT: In view of the problem of conventional display support equipment which has a poor intelligent, low technological level, easy to cause the body with sub-health, and can't meet the needs of high level office, designed a new type of display bracket mechanism. The principle and force analysis was carried out on the display bracket mechanism, and to simplify the original mechanism with three linkages for facilitating analysis and simulation. Forward kinematics analysis was carried out on the bracket mechanism based on DH method and obtained pose transformation matrix between each joint coordinate, and expressed the relationship between the end speed and the velocity of each joint by using Jacobian matrix. Establishing simplified virtual prototype and kinematics simulation was carried out on displacement, velocity, acceleration, angular velocity and acceleration of bracket mechanism based on the software of ADAMS which verified the correctness of theoretical analysis. The simulation results showed that the design of bracket mechanism complied with the requirements of free readjustment of display. Realizing the combination between high-tech and high emotion, improving the body with sub-health at the present situation of office, and meet the needs of advanced intelligent office by using the new display bracket mechanism
This work presents the kinematics model of an RA-
02 (a 4 DOF) robotic arm. The direct kinematic problem is
addressed using both the Denavit-Hartenberg (DH) convention
and the product of exponential formula, which is based on the
screw theory. By comparing the results of both approaches, it
turns out that they provide identical solutions for the
manipulator kinematics. Furthermore, an algebraic solution of
the inverse kinematics problem based on trigonometric
formulas is also provided. Finally, simulation results for the
kinematics model using the Matlab program based on the DH
convention are presented. Since the two approaches are
identical, the product of exponential formula is supposed to
produce same simulation results on the robotic arm studied.
