Lean Six Sigma


Now i can saying " I finished this book ( What is Lean Six Sigma )" . I have begun to read this book for five month ago. I know more time to read this book but i have more work behind reading ( My pre master & My job). I took more experience and ideas from this book. For example. How can i set small project? Howcan i pick up the project idea? How can i make time schudel? How can i market my product? And the important thing how can i reduce the waste in my process?
I recommend this book to read for every one want to improve his work or improve preformance for himself
for any one you can get this book from any e.Book site or give my your E-Mail (command) and i will send to you

My Graduation Project

Two Wheel Balancing Mobile Robot

Basic Idea

my graduation project is two wheel balancing mobile robot. . It is a small robot balanced with two parallel wheel only . The main idea of this project is how to make the robot balance. First we decide to use the gyroscope to make it balanced . gyroscope is angular sensor give us the tilt angle and the direction . it is a new technology used in air plane navigator, helicopter , tanks and segway. But we were failed to bought the gyroscope because it was expensive . so we are search for another component that can used in detect the tilt angle. Finally we decide to use two infrared sensors to detect the tilt angle of the robot to make it balanced


Design

We are used Catia system to design and draw our project . Catia is the best and first Cad/Cam system in the world . We used only cad system in our project . We are used part design, assembly, fitting, drafting and kinematics.




Electronic component

PIC16F876 Microcontroller


This power full ( 200 nanosecond instruction execution) , easy to program, have three port , analog to digital convert and acapture/compare/pwm.





L298 Dual Full-Bridge Driver


The L298 is used in balancing robot to drive the two DC motors. it is a high voltage , high current dual full bridge driver. two enable inputs are provide toenable or disaple the device independently of the input signals



Sharp GP2D120 Infrared Range Finder


The GP2D120 is a compact, self-contained ir ranging system incorporating an IR transmitter, receiver, optics, filter, detection, and amplification circuity the range of the sensor is between 5 to 30 cm


LCD Interface



LCD is the most inexpensive and simplest user interface you can provide when interfacing with such processors as the Basic Stamp, PIC, etc, in displaying user prompts, messafes and displaying data




Design & Make Electronic Board




Control


We are use Pic Basic Plus language to programming our robot . it is simple programming language and it is easy to use . it is similar to visual basic language that give use flexibility to use it . you can used assembly or C language to programming your robot . we were used pic basic to make PID control to our robot

Final Result



supervisor


Professor / Ahmed Elkeran

Mansoura University (Egypt)

Production & Mechanical Design Department

If you ask me about professor who has more information about production, mechanical, electronics, electricity and mechatronics? i only answer professor Ahmed Elkeran


Team WORK

My Ideas & Project

I thought more and more …. How I connect to the engineering society ? & How I can publish and show my engineering ideas and projects?????? . for it I was searched for the best way to show my ideas . finally I find the way. I decided to created this blog to publish my ideas , projects and searches.
