DEDICATIONS

I dedicate this design work to my family and all my friends for their inspiration and assistance even in times of difficulty.

ACKNOWLEDGEMENT

The completion of this project would have been impossible without the help received from many people. First I would like to thank the Almighty Father in heaven for having brought me this far. To God be glory forever and ever. I would also like to thank Dr. A.N. Mayaka for the priceless moral and technical advice he gave throughout the design process of this project. Thank you for the shared documents and materials and the precious time you gave, out of your ever busy schedule. I acknowledge the assistance of the Head of Department, Dr. Boaz Korir for coming to my aid when Dr. A.N. Mayaka was away. I would like to acknowledge all my lecturers for the tireless effort they have put in my training. Mr. Kimutai the effort you put towards this project cannot go unmentioned. I want to also extend my sincere appreciation to all the Mechanical Engineering Department technicians, specially mentioning Mr. Akwiri and Mr. Oduor My parents, I will not forget your self sacrifice in an effort to support me all through my college life. Last but not least, all my classmates, I am very grateful.

May God bless you all.
ABSTRACT
In this project an introduction on the need of adequate training on automation in higher learning institutions is looked into in a systematic way. First there is a general introduction of robotics in chapter one, robot classifications and robot applications is in chapters three and four. Chapter five consists of the design alternatives and their analysis. General introduction on component manufacture is given in chapter six. Cost analysis and the conclusion and recommendations are done in chapters seven and eight. TABLE OF CONTENTS
