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...

The kinematics of robot manipulators is a corner stone in the study of robotics in general. The computational complexity of the kinematics quite often prevents robotics instructors from using robots of general structure in their illustrative examples and assignments. The software discussed in this article, developed from recent research to support an undergraduate course in robotics, offers com...

In the context of controlling a robot arm with multiple joints, the method of estimating the joint angles from the given end-effector coordinates is called inverse kinematics, which is a type of inverse problems. Network inversion has been proposed as a method for solving inverse problems by using a multilayer neural network. In this paper, network inversion is introduced as a method to solve t...

This paper presents a 3D visual servo system using fuzzy controller for the command of a manipulator arm. The vision system is composed of two cameras; the first is installed above the robot, while the second is located on the lateral side of this one. These two cameras need no calibration, thus we can install them in any position and orientation with just the condition that the joints and the ...

In this study the current usage of each associated joint of a humanoid robot (NAO) during stand up process is analyzed. This study is the extension of our previous study [1] where the energy consumption of single and overall joints of a NAO robot during the walking process was researched while keeping the same stiffness values for all joints. This paper analyzes current stiffness relation of in...

In this paper, we propose a sliding mode controller for a robot manipulator with passive joints. A robot manipulator with passive joints which are not equipped with any actuators is a kind of underactuated system. Underactuated systems have some advantages compared to fully-actuated ones. For example, they weigh less and consume less energy because they have smaller number of components than fu...

This paper presents simplified hydrodynamics model for a biomimetic robot fish based on quantitative morphological and kinematic parameters of crangiform fish. The motion of four Pangasius sanitwongsei with different length and swimming speed were recorded by the digital particle image velocimetry (DPIV) and image processing methods and optimal coefficients of the motion equations and appropria...
