Available in PDF, EPUB and Kindle. Book excerpt: This master’s thesis presents a novel approach to finding trajectories with minimal end time for kinematically redundant manipulators. Emphasis is given to a general applicability of the developed method to industrial tasks such as gluing or welding. Minimum-time trajectories may yield economic advantages as a shorter trajectory duration results in a lower task cycle time. Whereas kinematically redundant manipulators possess increased dexterity, compared to conventional non-redundant manipulators, their inverse kinematics is not unique and requires further treatment. In this work a joint space decomposition approach is introduced that takes advantage of the closed form inverse kinematics solution of non-redundant robots. Kinematic redundancy can be fully exploited to achieve minimum-time trajectories for prescribed end-effector paths.

This book was released on 2010 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: Inverse Kinematics Solutions (IKS) as well as control of hyper-redundant robots are being under investigation by the robotics researchers due to the flexibility of configurations in achieving the same goal. End effectors attached at the tip of such robot are capable of reaching targets avoiding obstacles between the base of the robot and location of the target. Such robots can be programmed to continue operations successfully even after mechanical failure of few joints. However, it is very difficult to manage this flexibility due to the involvement of mathematical complexity in determining inverse kinematics of these robots, especially, handling of pseudo inverse of non-square matrices. Various techniques have so far been proposed by the researchers for inverse kinematics of hyper-redundant robots that involve wide range of mathematics including nonlinear optimization, Artificial Neural Network, Fuzzy Logic, etc. Most of these methods are often found to fail due to singular IKS. In this thesis a new technique has been proposed that assumes an initial configuration with a virtual layer. The virtual layer assumes an isosceles triangle formed of two subrobots each consisting of same number of links, and the imaginary line joining the location of the target and the base of the robot. Thus two sides of the isosceles triangle appear in singular configuration. In the successive steps the singularities are removed by first shifting the vertex towards the base of the triangle along the median of the triangle and then adjusting links on both subrobots to assume a coil shape. This ultimately leads to inverse kinematics of the hyper-redundant robot free from any singular configuration. Kinetics analyses are then done based on the IKS and appropriate actuators are selected accordingly. Total energy required to run the robot is found to depend on the selection of the point on the median line and is minimum corresponding to a point close to the base of the triangle. To verify the proposed IKS technique a laboratory scale four link prototype is built. Off-the-shelf servo motors are used as actuators in actuating the joints of the prototype. Results of the experiment show very good agreement with the analyses. Comparison of the proposed technique shows superiority over ANFIS, one of the recent techniques used for IKS of hyper-redundant robots. The proposed IKS technique and control approach is designed for planner robots with even number of links only. To make it generalized it needs to be studied for any number of links as well as robots in 3D space.

This book was released on 2020-07-23 with total page 220 pages. Available in PDF, EPUB and Kindle. Book excerpt: In order to control a robot we have to know its kinematics (what is attached to what, how many joints are there, how many degree of freedom, ect.). This book presents an approach that formalizes all of these mathematically for several robot configurations and get equations that can: 1) Convert from angular position of each joint (joint space) to the cartesian positions of the end effector called forward kinematics. 2) Convert from cartesian space to the joint space that is called inverse kinematics. The derived equations for forward kinematics and inverse kinematics have been invested in this work to represent the work space for different physical structures of robots. In this work an adopted user interface software (Visual Basic) that contains several types of windows have been built to simplify the solution for both forward and inverse kinematics for different robot configurations. In addition a program has been built using mat lab for representing, modeling and simulating the joint positions and the work space.
Download or read book Inverse Kinematic Analysis of Robot Manipulators written by Rachid Manseur and published by . This book was released on 1988 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: Computer controlled robot manipulators are becoming an important part of automated manufacturing plants thereby creating a need for reliable and fast control algorithms that can improve the performance of robot manipulators in industrial applications. An important part of such control algorithms is the inverse kinematics portion which consists of computing the values of the robotic joint variables corresponding to a desired and effector position and orientation. This work is based on a new approach that uses orthogonality of rotation matrices to reduce the problem to a simpler form. The reduction techniques are first used to analyze to the kinematics of four-degree-of-freedom (DOF) robots. The results obtained are then applied to the study of five- and six-degree-of-freedom manipulators. Fast one-and two-dimensional numerical techniques for solving five- and six-DOF arms of arbitrary geometry are developed. These new methods provide a large reduction in computational complexity and can be easily implemented in real-time applications. another contribution of this work is a classification of robot geometries in terms of inverse kinematic complexity. Some new sufficient structural conditions for the possibility of closed-form solutions for five- and six-DOF robot manipulators are described. In the case of six-DOF arms, structural conditions for the applicability of a one-dimensional iterative technique are also provided. Finally, in the example applications of the techniques presented here, we describe a six-degree-of freedom manipulator capable of achieving a particular end-effector pose in sixteen distinct configurations.

This book was released on 2019-11-06 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: Alexander Reiter describes optimal path and trajectory planning for serial robots in general, and rigorously treats the challenging application of path tracking for kinematically redundant manipulators therein in particular. This is facilitated by resolving both the path tracking task and the optimal inverse kinematics problem simultaneously. Furthermore, the author presents methods for fast computation of approximate optimal solutions to planning problems with changing parameters. With an optimal solution to a nominal problem, an iterative process based on parametric sensitivities is applied to rapidly obtain an approximate solution. About the Author: Dr. Alexander Reiter is a senior scientist at the Institute of Robotics of the Johannes Kepler University (JKU) Linz, Austria. His major fields of research are kinematics, dynamics, and trajectory planning for kinematically redundant serial robots as well as real-time methods for solving parametric non-linear programming problems.

Download or read book Robot Manipulator Redundancy Resolution written by Yunong Zhang and published by John Wiley & Sons. This book was released on 2017-11-13 with total page 319 pages. Available in PDF, EPUB and Kindle. Book excerpt: Introduces a revolutionary, quadratic-programming based approach to solving long-standing problems in motion planning and control of redundant manipulators This book describes a novel quadratic programming approach to solving redundancy resolutions problems with redundant manipulators. Known as ``QP-unified motion planning and control of redundant manipulators'' theory, it systematically solves difficult optimization problems of inequality-constrained motion planning and control of redundant manipulators that have plagued robotics engineers and systems designers for more than a quarter century. An example of redundancy resolution could involve a robotic limb with six joints, or degrees of freedom (DOFs), with which to position an object. As only five numbers are required to specify the position and orientation of the object, the robot can move with one remaining DOF through practically infinite poses while performing a specified task. In this case redundancy resolution refers to the process of choosing an optimal pose from among that infinite set. A critical issue in robotic systems control, the redundancy resolution problem has been widely studied for decades, and numerous solutions have been proposed. This book investigates various approaches to motion planning and control of redundant robot manipulators and describes the most successful strategy thus far developed for resolving redundancy resolution problems.

Download or read book Redundancy in Robot Manipulators and Multi Robot Systems written by Dejan Milutinović and published by Springer Science & Business Media. This book was released on 2012-10-12 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: The trend in the evolution of robotic systems is that the number of degrees of freedom increases. This is visible both in robot manipulator design and in the shift of focus from single to multi-robot systems. Following the principles of evolution in nature, one may infer that adding degrees of freedom to robot systems design is beneficial. However, since nature did not select snake-like bodies for all creatures, it is reasonable to expect the presence of a certain selection pressure on the number of degrees of freedom. Thus, understanding costs and benefits of multiple degrees of freedom, especially those that create redundancy, is a fundamental problem in the field of robotics. This volume is mostly based on the works presented at the workshop on Redundancy in Robot Manipulators and Multi-Robot Systems at the IEEE/RSJ International Conference on Intelligent Robots and Systems - IROS 2011. The workshop was envisioned as a dialog between researchers from two separate, but obviously related fields of robotics: one that deals with systems having multiple degrees of freedom, including redundant robot manipulators, and the other that deals with multirobot systems. The volume consists of twelve chapters, each representing one of the two fields.
