qDefinition of Robot

A re- programmable, multifunctional manipulatordesigned to move material, parts, tool, or

specialized devices through various programmed

motions for the performance of a variety of tasks

q Great Moments in Robot History

Third Century B.C. Aristotle gets the robo-ball rolling by penning these words: "If

every instrument could accomplish its own work, obeying or anticipating the will of

others.

Eighteenth Century Automatons, These mechanically animated dolls can play musical

instruments, draw, and quack like a duck (well, the duck one could, anyway).

1801 Joseph Jacquard invents a "programmable loom" that operates via punch cards.

1898 Nicola Tesla, inventor of the induction motor, alternating current (AC)

transmission, and the actual inventor of radio

1956 MIT's John McCarthy coins the term "Artificial Intelligence" during a

Dartmouth computer workshop.

1973Ichiro Kato develops WABOT-1, the first humanoid walking robot.

1976 Robot arms in space.

1984 Mobile robots doing actual work

1994 CMU's six-legged extreme environments robot, aptly named Dante II.

1997 Honda stuns the world with its P3 humanoid robot.

1999 Sony begins selling its AIBO robotic pet. The product is almostaffordable and extremely sophisticated.

q Advantages of Robots

Robots increase productivity, safety, efficiency, quality, and consistency of products.

Robots can work in hazardous environments without the need.

Robots need no environmental comfort.

Robots have repeatable precision at all times.

Robots can be much more accurate than human.

Robots replace human workers creating economic problems.

Robots can process multiple stimuli or tasks simultaneously.


5/12

q Disadvantages of Robots

Robots lack capability to respond in emergencies.

Robots, although superior in certain senses, have limited capabilities in Degreeof freedom, Dexterity, Sensor, Vision system, real time response.

Robots are costly, due to Initial cost of equipment, Installation costs, Need forPeripherals, Need for training, Need for programming.

q Robot classification

The Japanese Industrial Robot Association (JIRA) is also chiefly concerned with industrial robotics-

Manually operated manipulators: Machines slaved to a human operator

Sequential manipulators: Devices that perform a series of tasks in the same sequence every time

they're activated

Programmable manipulators: An assembly-line robotic arm.

Numerically controlled robots(Playback): Robots that are instructed to perform tasks through the

receipt of information on sequences and positions in the form of numerical data.

Sensate r obots: Robots that incorporate sensor feedback into their circuitrytouch sensors,

proximity sensors, vision systems, and so forth.

Adaptive robots: Robots that can change the way they function in response to their environment.

Smar t robots: Robots that are considered to possess artificial intelligence (AI).

Intelligent mechat ronic systems: Here it refers to smart devices and embedded(Mechatronics)

systems

q Construction & working of the Robot

Mechanical platforms-The hardware base

Driving Mechanism

Actuators

R/C Servos

Sensors

Micro-processor System- Including Artificial Intelligence(AI)

Languages

Driving High current loads from logic

Controllers

q Robot Anatomy

Base

Link0

Joint1

Link2

Link3Joint3 End of Arm

Link1

Joint2

1. Manipulator consists of joints and links-

Joints provide relative motion

Links are rigid members between joints

Various joint types: linear and rotaryEach joint provides a degree-of-freedom

Most robots possess five or six degrees-of-freedom

2. Robot manipulator consists of two sections-

Body-and-arm for positioning of objects in therobot's work volumeWrist assembly for orientation of objects


9/12

q Robot Languages

Microcomp uter M achin e Language Level: The most basic and very efficient but

difficult to understand to follow.

Poin t-to-Poin t Level : Funky Cincinnati Milacrons T3, It lacks branching,sensory information.

Primitive Motion Level: VAL by Unimation Interpreter based language.

Structured Programm ing Level: This is a compiler based but more difficult tolearn.

Task-Oriented Level: Not exist yet and proposed IBM in the 1980s.


10/12

q Industr ial Robot Applications

Material handling applications-1. Material transfer pick-and-

place, palletizing2. Machine loading and/or

unloading

Processing operations-1. Welding

2. Spray coating3. Cutting and grinding

Assembly and inspection-

q FANUC LR Mate 200iBBasic Description: The LR Mate 200iB is a six-axis, modular construction, electric

servo-driven, tabletop robot designed for a variety of manufacturing and systemprocesses.
