You n1-ay have seen n1-achines that artisans n1ade that try to inuc hun1an n1-otions and behavior. Exan1ples in. Toys, fron1 si1nple types to sophisticated 1nachines with rep eating n1ove1nents, are other exan1ples. Although in principle humanoids are robots and are designed and governed by the san1e basics, in this book, we will prin1.
This book covers so1ne basic introductory n1aterial that familiarizes you with the subject; it presents an analysis of the mechanics of robots including kinen1atics, dynarnics, and traj ectory planning; and introduction to robotics niku pdf download discusses the elen1ents used in robots and in robotics, such as actuators, sensors, vision systen1s, and so on.
Robot rovers are no different, although they usually have fewer degrees of freedom and generally move in a pla11e. Exoskeletal and hun1anoid robots, walking 1nachines, and robots that c animals and insects h ave n1any degrees offreedom DOF and may possess unique capabilities.
However, the same principles vve learn about n1anipulators apply to robot rovers too, whether kinen1-atics, differential n1otions, dynan1-ics, or control.
Robots are very powerful elements of today's industry. They are capable of perforn1- ing n1any different tasks and operations, are accurate, and do not require coon safety and cornfort elem. H owever. Early industrialist predictions about the possible nun1ber of robots. Figu1e 1. As a result, although there are 1nany thousands of robots in industry working tirelessly and satisfactorily for the intended jobs, robots have not overvvheln1- ingly replaced ,;vorkers.
Like hun1ans, robots can do certain things, but not others. As long as they are designed properly for the intended pu1poses, they are very useful and continue to be used. The subject of robotics covers n1any different areas. R obots alone are hardly ever useful. They are used together with other devices, peripherals, and other 1nanufacturing n1achines, introduction to robotics niku pdf download.
They are generally integrated into a system, which as a ,vhole, is designed to perforn1 a task or do an operation. In this book, we will refer to son1e of these other devices and systen1. If you con1. Both possess a nun1ber offu1ks attached serially to each other,-vithjoints, where each joint can be In both systen1s, the "hand" of the n1. Each one can carry a certain load and is controlled by a central controller that controls the actuators. However, one is called a robot and one is called a n1anipulator or, in this case, a crane.
Similarly, n1. The funda1nental difference betvveen the two is that the crane and the manipulator are controlled by a hun1. Figure 1. Printed with permission from Dalrnec S.
Reprinted with permission from Faauc R. Ainerica, lnc. Both have sirnil. This difference between the two dete1nlines whether a device introduction to robotics niku pdf download a simple manipulator or a robot. In general, robots are designed and meant to be controlled by a con1puter or sinlilar device.
The n1otions of the robot are controlled through a controller under the supervision ofthe computer, whicl1is 1unning se type ofa program. Therefore, if the progran1 is changed, the actions of the robot ,vill change accordingly.
The intention is to have a device that can perforn1 rnany different tasks; consequently, it is very :flexible in what it can do without having to be redesigned. T herefore, the robot is designed to be able to pe1for1n n1any tasks based on the running progran1 s sin1ply by changing the progran1. The sin1ple 1nanipulator or the crane cannot do this with out an operator running it all the tin1e. Different introduction to robotics niku pdf download have different standards for what they introduction to robotics niku pdf download a robot.
In An1erican standards, a device must be easily reprogranable to be considered a robot. Therefore, n1anual handling devices devices that have n1ultiple degrees of freedon1 and are actuated by an operator or fixed sequence robots devices controlled by hard stops to control actuator n1otions on a fixed sequence that are difficult to change are not considered robots. Fundarnentals Class 2: Fixed Sequence Robot: a device that pe1forms the successive stages of a task according to a predetern1ined, unchanging n1ethod, vvhich is hard to modify Class 3: Variable Sequence Robot: sa1ne as in class 2, but easy to n1odify Class 4: Playback Robot: a hurn.
Type A: handling devices with 1nanual control to telerobotics Type B: auton1atic handling devices ,vith predetermined cycles Type C: progran1n1able, servo controlled robots with continuous or point-to-point trajectories Type D: san1e as C but with capability to acquire inforn1ation fro1n its environn1ent.
Robotics is th e art, kno,vledge base, and the know- ho,v of designing, applying, and using robots in hun1an endeavors. Robotic syste1ns consist of not just robots, but also other devices and systen1s used together with the robots.
Robots n1ay be used in n1anufacturing environn1ents, in undervvater and space exploration, for aiding the clisabled, or even for fun. In any capacity, robots can be useful, but they need to be progran1n1ed and controlled. Capek drea1ned of a scenario where a bioprocess co uld create hun1an-like machines, devoid of en1otions and souls, who vvere strong, obeyed their m.
Soon, the Eventually, the robots decided that they were actt1ally superior to the humans, took over the whole ,vorld, and ki1Jed everyone. In this story, th.

T he first robots were controlled by strips of paper with holes, which electric eyes cou1d detect and which controlled the robot's overn en ts. As industry i1nproved, the strip of paper gave way to magnetic tapes, to meory devices, and personal con1. T he following is a summary of events th. Robots and introduced the word rabota worker. Eckert an. The first robot was imported to Japan for paint spraying applications.
It eventually developed the IBM for sale. M any progra TM was sold to Introduction to robotics niku pdf download estinghouse Corporation, ,vho subsequently sold it to the Staubli of Switzerland in First Asi1n.
Fundamentals 1. Robots can work in hazardous environments such as radiation, introduction to robotics niku pdf download, darkness, hot and cold, ocean botton1s, space, and so on without the need for introduction to robotics niku pdf download support, con1fort, or concern for safety.
Robots need no environn1ental comfort hke ligl1ti11g, air conditioning, ventilatio11, arid 11oise protection. Robots work conti11uously without tiring or fatigue or boredon1. They do not get mad, do not have hangovers, and r1eed no medical insurance or vacation. Robots have repeatable precision at al1 ties unless so1nething happens to the1n or unless they.
Robots can be 1nuch n1ore accurate than hu1T1a11s. Typical linear accuracies are a few ten- thousandths of an inch.
New wafer- handling robots have m. Robots and tl1eir accessories a11d sensors can have capabilities beyond those ofhun1ans. Robots can process n1tiltiple stin1uli or tasks si1nulta11eously, introduction to robotics niku pdf download. Hun1a11s can only process one active stin1ulus, introduction to robotics niku pdf download. Robots replace hu1nan workers, causing econo1nic hardship, worker dissatisfaction and resentment, and the need for retrai11ing the replaced workforce.
Robots lack capability to respond in emergen. Robots are costly due to : o Witlt other ele1nents, the 1nanipulator alone is not a robot Figure 1. End effe ctor: T his part is connected to the last joint hand of a anipulator that generally handles objects, 1nakes connections to other n1achines, or performs the required tasks Figure 1.
Robot manufacturers generally do not design or sell end effectors. In ost cases, all they supply is a si1nple gripper. Generally, the hand of a robot has provisions for connecting specialty end effectors specifically designed for a purpose. This is the job of a con1pany's engineers or outside consultants to design and install the end effector on the robot, introduction to robotics niku pdf download, and to make it work for the given situation.
A welding torch, a paint spray gun, a glue laying device, or a parts handler are but a few possibilities, introduction to robotics niku pdf download. In n1ost cases, the action of the end effector is either controlled by the robot's controller, or the controller comunicates with the end effector's controlling device such as a PLC. Introduction to robotics niku pdf download Actuators are the "1nuscles" of the anipulators. T he controJler sends signals to the actuators, which, in turn, n1ove the robot joints and links.
Coon types are servomotors, stepper 1notors, pneu1natic actuators, and hydraulic actuators. O ther novel actuators are used in specific situations this will be discussed later in Chapter 7. Actuators are under the control of the controller. As in hu1nans, the robot controller needs to knovv the location of each link of the robot in order to know the robot's configuration, introduction to robotics niku pdf download. When you v.
This is because feedback sensors in your central nervous system en1bedded in rnuscle tendons send information to the brain. The brain uses this info1mation to deter1nine the length of your n1uscles and, consequently, the state of your arn1s, legs, and so on. The san1e is true for robots, where sensors integrated into the robot send inforn1ation about each joint or link to the controller that detennines the configuration of the robot.
