This paper presents a simple and intuitive approach to determining the kinematic parameters of a serial-link robot in Denavit and Hartenberg notation. Once a manipulator’s kinematics is parameterized in this form a large body of standard algorithms and code implementations for kinematics, dynamics, motion planning and simulation are available. The proposed method has two parts. The first is the...

This paper deals with the kinematic synthesis of manipulator. A new method based on distributed solving is used to determine the dimensional parameters of a general manipulator which is able to reach a set of given tasks speciied by orientation and position. First, a general Distributed Solving Method (DSM) is presented in three steps : the problem statement, the objective functions formulation...

Krang is a 19 degree of freedom robot with actuators along three different major axes with a unique physical structure. Moreover, in comparison to most robots on which kinematics is studied, Krang is neither a stationary robot with a fixed base nor is it a legged humanoid for which somewhat a standard has been established. Still, we would like the kinematics for Krang to be easy to understand, ...

Dynamic identification models allow for system parameters such as mass and inertia to be computed by combining knowledge of the system’s configuration, and the forces applied to the system. These methods are often used to calibrate individual dynamic models in robots, and have also been used to estimate human parameters. While commonly used, the Denavit-Hartenberg approach can lead to modelling...

Robots find their applications in various fields and are used to perform repetitive and adaptive tasks very accurately. This requires exact kinematic parameters of the robot. Generally, for a serial robot, these parameters are represented using the Denavit-Hartenberg (DH) parameters, whose nominal values are provided by the robot manufacturers. In this paper, a technique is proposed to determin...

RoboAnalyzer is a software based on 3Dmodel of robots. It was developed primarily for teaching and learning of robot mechanics, although it is robust enough for the use by researchers as well. The motive behind the development of RoboAnalyzer was mainly to help teachers and students get started with teaching/learning of robotics using template-based skeleton models or CAD models of serial robot...
