Preliminary investigation for the design of mechanical physiotherapist to deflect a robotic arm by 10° / Lee Chee Keong

Preliminary investigation for the design of mechanical physiotherapist to deflect a robotic arm by 10°_Lee Chee Keong_E3_2008_NI
Fisioterapi adalah suatu proses melibatkan gerakan manusia and berfungsi untuk memaksimumkan kebolehan seseorang. Dalam project ini, suatu lengan robot digunakan untuk menjalankan latihan fisioterapi. Lengan robot tersebut dicipta and disimulasi dengan menggunakan perisian “Computer Aided Design (CAD)” yang dikenali sebagai “SolidWorks” sebelum ia dibina dan dipasangkan. Lengan robot tersebut berupaya membengkok pada sudut 10°, 20°, dan 30°. Bengkokan ini membolehkan pesakit merehatkan tangannya di atas lengan robot tersebut. Bukan itu sahaja, lengan robot tersebut juga berupaya menolong pesakit menjalankan latihan pemulihan yang mudah. Bagi mengawal gerakan lengan robot itu, satu perisian khas ditulis dengan menggunakan perisian daripada Microsoft iaitu dikenali sebagai “Visual Basic 6”. Untuk membolehkan lengan robot berfungsi dengan sempurna, isyarat dari computer dimanipulasikan. Jika perisian yang ditulis berfungsi dengan bersendirian, ia tidak dapat mengawal gerakan lengan robot itu. Dengan itu, litar elektrik and elektronik yang bersesuai mesti dicipta and dilaksanakan. Oleh kerana isyarat dari computer tidak dapat mengerakan motor di lengan robot, suatu pemandu digunakan dalam litar. Pemandu adalah terdiri daripada komponen elektrik dan elektronik seperti transistor, perintang dan geganti. Geganti digunakan untuk mengawal arus voltan yang mengalir ke motor pada lengan robot. Untuk memandukan geganti tersebut, isyarat dari komputer dikuatkan dengan menggunakan transistor. Dengan itu, arus kecil dari computer dapat memandukan motor di lengan robot supaya ia dapat berfungsi and membengkok dengan sempurna. _________________________________________________________________________________________ Physiotherapy is a health care profession related with human movement and function to maximizing potential. In this project, a robot arm is used to conduct the physiotherapy exercises. The robot arm is designed and simulated using a Computer Aided Design (CAD) tool called SolidWorks before it is fabricated and assembled. The robot arm must be able to deflect by 10°, 20°, and 30°. This deflection may help to support the arm of the patient. Not only that, the robot arm is also able to help the patient to do simple exercises. To control the movement of the robot arm, a special program is developed using Microsoft Visual Basic 6. The signal form computer is manipulated so that the robot arm can function perfectly. The program alone does not able to control the robot arm. As a result, a suitable electrical and electronic circuit is designed and implemented. Because of the signal from computer does not able to drive the motor in the robot arm, a driver is used in the circuit. The driver consists of some electronic and electrical components like transistors, resistors and relays. Relays are used to control the high current voltage to the motor in the robot arm. To drive the relay, the signals from computer are amplified using transistors. A small current signal from computer is able to drive the motor in the robot arm so that it can able to function and deflect perfectly. As a result, the robot arm will be able to deflect by 10°.
