In Page I Will Show You The Pictures Of My Final Project Before Earning My Diploma In UNITEN. The Title Is PC-Based Wireless Control Of Mobile Robot. The Main Goal Of This Project Is To Control A Device, In This Case A Robot Via A Computer. All The Transition Of Data Between The PC And That Device Is Done Wirelessly. 

To Accomplish The Objective Of This Project I Should Be Able To Know Wireless System (RF), Which In This Case Is Using FM. A Lots Of Programming (VB6). DC-Motor Characteristic. Shaft Diffential System And Lastly The Circuit Theory Between The Device. 

The Program That Been Written Not Only Allowed The User Control The Device, It Must Also Capable To Show The Position Of The Device, Adapt The Pre-Path Assigned By The User And Sent A Visual Back To The User's PC. The Last Capabilities Is Quite Hard To Accomplish And I'm Cannot Promise Anything About This. This Is Because The Device (Visual Transition) Is Very Expensive And I Don't Think I Will Have Enough Time. 

To Communicate Between The Program And The Transmitter I Choose To Use The Parallel Port a.k.a Printer Port. The Reason To Use This Port Is Because Parallel Port Have The Capabilities To Sends 8 Bits Of Data (1 Byte) At A Time. These 8 Bits Are Transmitted Parallel To Each Other. The Standard Parallel Port Is Capable Of Sending 50 To 100 Kilobytes Of Data In  A Second.

Until Today (19th January 2004) I Already Finished Build The Robot Body (I Choose A Shovel/Dozer Type From TAMIYA Corp.). From This I Will Transform It To A Wireless Device (Original Design Is Not). After That I Will Calculate The Amount Of Power Produce By Both Of It's Motor. Only After I Get All This Data, I Will Be Able To Make A Final Program (Beta Version Was Already Completed). 

I Always Remember That Many Of The Information Is Building/Creating/Designing This Robot And This Project, Were Collected From Many Of My Friends All Over The World Whose Many Of Them Are Qualified Engineer (Both Electrical And Mechanical), Computer's Programmer, Computer's Hacker And Robot Enthusiasts. So I Promise To Publish All My Work Regarding This Project To World Wide Web (WWW). I Always Believe That We Need To Share Our Expertise To Other Because We Get It Also From Others. 

Many Thanks And Tribute To My Project Supervisor, Mr. Zulkifli Ishak. My Academic Advisor, Mr. Ya'acob Raja Omar. Thanks For Introduce Me To The Exciting/Thrilling/Dangerous World Of Robotic And The Hardcore World Of Computer (Both Architectures And Programming).

Yesterday (23/01/04) I Finished Writing A Program To Trace All The Movement Of My Mobile Robot. I'll Show You The Picture....

The Top Side Of The Picture Show The Maze That Will Be The Path For The Robot. User Then Will Enter The Direction And Will Also Enter The Length Of The Movement. After All This Complete, User Will Need To Click The Start Button And The Robot Will Move Accordingly. Next I'll Show You The Picture When The Execution Completed.

I Had Already Completed Build The Mobile Robot Body Complete With 2 Receiver, 2 DC Motor And All The Essential Things/Components. After The Robot Completed I Test It. At First The Robot Move Accordingly. But After A Few Experiment I Encountered That The Left Track Move Much Slower Than The Right Track. At First I Suspect The Problem Come From The Overall Weight. Then I Done A Few Other Experiment And I Very Sure The Problem Is Nothings To Do With The Weight. After I Get The Latest Picture I Will Surely Publish It Here.

The Cause Of Unparallel Move Between Track 1 And Track 2 Was Identified. The "Tin" Used In Soldering Process Accumulate A Huge Resistance. This Problem Is A Very Major Concerned Especially To Left Track.
