Mobile robots that consist of a mobile platform with one or many manipulators mounted on it are of great interest in a number of applications. Combination of platform and manipulator causes robot operates in extended work space. The analysis of these systems includes kinematics redundancy that makes more complicated problem. However, it gives more feasibility to robotic systems because of the e...

The kinematics of manipulators is a central problem in the automatic control of robot manipulators. Theoretical background for the analysis of the 5 Dof Lynx-6 educational Robot Arm kinematics is presented in this paper. The kinematics problem is defined as the transformation from the Cartesian space to the joint space and vice versa. The Denavit-Harbenterg (D-H) model of representation is used...

The kinematics of manipulator is a central problem in the automatic control of robot manipulators. Theoretical background of the analysis of the MA-2000 educational robot arm kinematics is presented in this paper. The revolute robot consists of six rotary joints (6-DOF) with base, shoulder, elbow, wrist pitch, wrist yaw and wrist roll. The kinematics problem is defined as transformation from th...

Kinematics studies the motion of bodies without consideration of the forces or moments that cause the motion. Robot kinematics refers the analytical study of the motion of a robot manipulator. Formulating the suitable kinematics models for a robot mechanism is very crucial for analyzing the behaviour of industrial manipulators. There are mainly two different spaces used in kinematics modelling ...

the main objective of this article is to optimize the walking pattern of a 2d humanoid robot with heel-off and toe-off motions in order to minimize the energy consumption and maximize the stability margin. to this end, at first, a gait planning method is introduced based on the ankle and hip joint position trajectories. then, using these trajectories and the inverse kinematics, the position tra...

Abstract—Robot kinematics and dynamics is the basis of robotics research, providing the important basis for robot path planning and motion control etc. The paper focuses on the six degrees of freedom industrial robot which is developed independently, adopts the D-H method to do the forward kinematics analysis and inverse kinematics analysis for robot, establishes the kinematics model, and uses ...

This paper presents simulation and experimental results of position-based visual servoing control process of a 6R robot using 2 fixed cameras. This method has the ability to deal with real time changes in the relative position of the target-object with respect to robot. Also, greater accuracy and independency of servo control structure from the target pose coordinates are the additional advanta...

In order to obtain the optimal structure parameters of a quadruped robot, in this paper, a four-legged mammal (dog) is used as a model, and a quadruped robot configuration framework is set up by simplification of the model’s structure. In addition, the kinematics model of this robot is established. Based on the analysis of quadruped robot's kinematics characteristics, and taking the flexibility...
