C364(h)* - Industrial Robotics

Brief Description

This course introduces the important elements of robotics through particular emphasis on automatic flexible assembly. The emphasis of the material is to provide an understanding of the software aspects of flexible automated assembly, though set in the wider context of general robotics and other computer-based automation. The particular challenges of this application area are presented along with the techniques currently available to tackle them.

an overview of robotics for software engineers;
the software issues in the discipline as examples and extensions of the concepts introduced in other modules;
the problems characteristic of the discipline;
the range of techniques and algorithms brought to bear on these problems.

Objectives

On successful completion of this half unit, students should

have an understanding of basic robotic equipment;
have an understanding of the basic functional requirements of a software system for robot task definition;
be familiar with the specifically robotics facilities of a range of robot programming languages and environments;
understand the range of planning problems in the field and have a knowledge of some representative techniques used to solve them;
understand the challenge which robotics and the `behaviours' model represent to traditional AI techniques.
