1. UNIT 5 INTRODUCTION
Definition of a Robot - Basic Concepts - Robot configurations - Types of Robot drives - Basic robot motions -Point to point control - Continuous path control.

2. Definition of a Robot
A machine that looks and acts like a human being.
An efficient but insensitive person
An automatic apparatus.
Something guided by automatic controls.
E.g. remote control
A computer whose main function is to produce motion.

3. Law’s of Robotics Asimov proposed three “Laws of Robotics”
Law 1: A robot may not injure a human being or through inaction, allow a human being to come to harm
Law 2: A robot must obey orders given to it by human beings, except where such orders would conflict with a higher order law
Law 3: A robot must protect its own existence as long as such protection does not conflict with a higher order law

4. Robot anatomy Robot manipulator consists of two sections:
Body-and-arm – for positioning of objects in the robot's work volume
Wrist assembly – for orientation of objects

5. Wrist Wrist assembly is attached to end-of-arm
End effector is attached to wrist assembly
Function of wrist assembly is to orient end effector
Body-and-arm determines global position of end effector
Two or three degrees of freedom:
Roll
Pitch
Yaw

7. Robot configurations Rectangular (or) Cartesian
Cylindrical (or) Post-type
Spherical (or) Polar
SCARA (Selective Compliance Assembly Robot Arm)
