Bueno, realmente la tesis no contaba con un cap´ıtulo de ’agradecimientos’ sino mas´ bien con un cap´ıtulo alternativo titulado ’viaje a Agra de Cimientos’. En dicho capitulo, el ahora ya doctor redacto´ un pequeno˜ cuento epico´ inventado por el´ mismo. Esta pequena˜ historia relataba las aventuras de un caballero, al mas´ puro estilo ’Tolkiano’, que cabalgaba en busca de un pueblo recondito.´ Ya os podeis´ imaginar que dicho caballero, no era otro sino el´ mismo, y que su viaje era mas´ bien una odisea en la cual tuvo que superar mil y una pruebas hasta conseguir su objetivo, llegar a Agra de Cimientos (terminar su tesis). Solo´ deciros que para cada una de esas pruebas tuvo la suerte de encontrar a una mano amiga que le ayudara. En mi caso, no voy a presentarte una tesis, sino los apuntes de la asignatura ”Robot Control and Programming´´ que se imparte en ingles.´ Aunque yo no tengo tanta imaginacion´ como la de aquel doctorando para poder contaros una historia, s´ı que he tenido la suerte de encontrar a muchas personas que me han ayudado en mi viaje hacia ’Agra de Cimientos’. Y eso es, amigo lector, al abrir estas notas de clase vas a ser testigo del final de un viaje que he realizado de la mano de mucha gente que de alguna forma u otra han contribuido en su mejora.

  • Creating and Running a Dynamic Analysis a Force Simulating The
    Creating and Running a Dynamic Analysis A force simulating the engine firing load (acting along the negative X-direction) will be added to the piston for a dynamic simulation. It will be more realistic if the force can be applied when the piston starts moving to the left (negative X-direction) and can be applied only for a selected short period. In order to do so, we will have to define measures that monitor the position of the piston for the firing load to be activated. Unfortunately, such a capability is not available in COSMOSMotion. Therefore, the force is simplified as a step function of 3 lbf along the negative X-direction applied for 0.1 seconds. The force will be defined as a point force at the center point of the end face of the piston, as shown in Figure 5-21. Before we add the force, we will turn off the angular velocity driver defined at the joint Revolute2 in the previous simulation. We will have to delete the simulation before we can make any changes to the From the browser, expand the Constraints branch, and then the Joints branch. Right click Revolute to bring up the Edit Mate-Defined Joint dialog box (Figure 5-22). Pull-down the Motion Type and choose Free. Click Apply to accept the change. Note that if you run a simulation now, nothing will happen since there is no motion driver or force defined (gravity has been turned off). Now we are ready to add the force. The force can be added from the browser by expanding the Forces branch, right clicking the Action Only node, and choosing Add Action-Only Force, as shown in Figure 5- 23.

Direct kinematics refers to the calculation of end joint is defined by the amount of linear slide of one relative effectors position, orientation, velocity, and acceleration when to the other one. This one parameter movement identifies the corresponding joint values are known. Inverse refers to the this joint as a one degree of freedom kinematic pair. opposite case in which required joint values are calculated for given end effector values, as done in path planning. Some special aspects of kinematics include handling of redundancy collision CYLINDRICAL JOINT: avoidance, and singularity avoidance. Once all relevant positions, A cylindrical joint is two degrees of freedom kinematic pair velocities, and accelerations have been calculated using used in mechanisms. Cylindrical joints provide single-axis kinematics, this information can be used to improve the control sliding function as well as a single axis rotation, providing a algorithms of a robot. Most of the industrial robots are described way for two rigid bodies to translate and rotate freely. This geometrically by their Denavit-Hartenberg (DH) parameters, which are also difficult to perceive for students. Students will find can be pictured by an unsecured axle mounted on a chassis, the subject easier to learn if they are able to visualize in 3 as it may freely rotate and translate.

    1. Terminology and Definitions-Degree of Freedom, Mobility Kinematics: The study of motion (position, velocity, acceleration). A major goal of understanding kinematics is to develop the ability to design a system that will satisfy specified motion requirements. This will be the emphasis of this class. Kinetics: The effect of forces on moving bodies. Good kinematic design should produce good kinetics. Mechanism: A system design to transmit motion. (low forces) Machine: A system designed to transmit motion and energy. (forces involved) Basic Mechanisms: Includes geared systems, cam-follower systems and linkages (rigid links connected by sliding or rotating joints). A mechanism has multiple moving parts (for example, a simple hinged door does not qualify as a mechanism). Examples of mechanisms: Tin snips, vise grips, car suspension, backhoe, piston engine, folding chair, windshield wiper drive system, etc. Key concepts: Degrees of freedom: The number of inputs required to completely control a system. Examples: A simple rotating link. A two link system. A four-bar linkage. A five-bar linkage. Types of motion: Mechanisms may produce motions that are pure rotation, pure translation, or a combination of the two. We reduce the degrees of freedom of a mechanism by restraining the ability of the mechanism to move in translation (x-y directions for a 2D mechanism) or in rotation (about the z- axis for a 2-D mechanism). Link: A rigid body with two or more nodes (joints) that are used to connect to other rigid bodies. (WM examples: binary link, ternary link (3 joints), quaternary link (4 joints)) Joint: A connection between two links that allows motion between the links.

Acknowledgments This study acknowledges with sincere gratitude and thanks the patience and guidance of my thesis advisor, Dr. Nir Berzak. Without his extreme accessibility and invaluable advice, this thesis would never have gotten its shape. Thanks are due to Dr. Richard Budynas, my program advisor for his support throughout my M.S. program. Sincere gratitude is extended to Dr. Joseph Torok and Dr. Wayne Walter for spending their valuable time in reviewing this work. Special thanks to Ms. Sandy Grooms of Department of Engineering Support who helped me in getting the typed version of this report. Last but not least deep gratitude is expressed to my mother, my brother, my sister and her family for their never-ending patience and support. ABSTRACT Mechanisms are means of power transmission as well as motion transformers. A four- bar mechanism consists mainly of four planar links connected with four revolute joints. The input is usually given as rotary motion of a link and output can be obtained from the motion of another link or a coupler point.

  • Robot Geometry and Kinematics
    V. Kumar 5. Introduction to Robot Geometry and Kinematics The goal of this chapter is to introduce the basic terminology and notation used in robot geometry and kinematics, and to discuss the methods used for the analysis and control of robot manipulators. The scope of this discussion will be limited, for the most part, to robots with planar geometry. The analysis of manipulators with three-dimensional geometry can be found in any robotics text1. 5.1 Some definitions and examples We will use the term mechanical system to describe a system or a collection of rigid or flexible bodies that may be connected together by joints. A mechanism is a mechanical system that has the main purpose of transferring motion and/or forces from one or more sources to one or more outputs. A linkage is a mechanical system consisting of rigid bodies called links that are connected by either pin joints or sliding joints. In this section, we will consider mechanical systems consisting of rigid bodies, but we will also consider other types of joints. Degrees of freedom of a system The number of independent variables (or coordinates) required to completely specify the configuration of the mechanical system. While the above definition of the number of degrees of freedom is motivated by the need to describe or analyze a mechanical system, it also is very important for controlling or driving a mechanical system. It is also the number of independent inputs required to drive all the rigid bodies in the mechanical system. Examples: (a) A point on a plane has two degrees of freedom.
