designing, building and testing a simple
mobile robot

“A reprogrammable multi
-
functional manipulator
designed to move materials, parts, tools, or
specialized devices through varied programmed
motions for the performance of a variety of
tasks”.



The idea of a robot was first introduced by the Czech
writer Karel Capek in his play Rossum’s Universal
Robots published in 1920.



Capek’s robots are closer to the modern idea of
Androids such as one might see in a programme such
as Star Trek etc.


Modern Technology is making rapid strides towards
making such robots a real possibility.


The field of study concerning robots is known as
Robotics a word first used by Asimov in his work
“Three Laws of Robotics”

*
Robots come in all shapes and sizes performing a huge array
of tasks from simple applications to extremely complex
operations.


*
The most advanced robotic systems are usually mobile and
able to “become aware” of their surroundings through their
sensors.


*
Robotic systems which are able to “learn” are controlled by a
technology known as Artificial Neural Networking (ANN)
