Abstract

The main objective of this paper is how Robot motion is controlled with the help of Kinematics principles and other graphic motions, In this paper we primarily focused on different Robot motions and how they are related to Kinematic principles . Here we are going to take Robot Arm and how it is moved with respect to Kinematic principles . the analytical study of the geometry of motion of a mechanism:

¢ With respect to a fixed reference co-ordinate system,¢ without regard to the forces or moments that cause the motion. In or ....etc

Chance of Loss
The Probability that an event that causes a loss will occur

Objective probability
A PRIORI Probability: Determined by deductive reasoning / Logical deductions such as in games of chance.
Empirically determined by inductive reasoning through analysis of data

Subjective probability: A personal estimate of the chance of loss. It need not coincide with objective probability and is influenced by age, sex, intelligence, educa ....etc

BASIC REFRIGERATION PRINCIPLES
If you were to place a hot cup of coffee on a table and leave it for a while, the heat in the coffee would be transferred to the materials in contact with the coffee, i.e. the cup, the table and the surrounding air. As the heat is transferred, the coffee in time cools. Using the same principle, refrigeration works by removing heat from a product and tran ....etc
