Week 4

Week 4 is Eidul Fitri ceremony week.
A little progress was done during this week by designing the sensor (potentiometer) holder that needed to be attached on the surface of the mechanical part.
This is important element for this overall project because the sensor act as feedback for micro-controller to operate. Without it, the ROM cannot be measured correctly.
This is basic sketch for the sensor holder

Week 3

For electronics circuit, I have done some research on what components that are related this project during previous semester. But this time, the research is more toward on micro-controller circuit which is Arduino board. These are components that I have bought for testing the project. All the components are bought at Jalan Pasar near Pudu.

List of components:

1.   Potentiometer
2.   Push buttons
3.   Crystal 16Mhz
4.   Resistor
5.   Ceramic capacitors
6.   Electrolytic capacitors
7.   Liquid Crystal Display (LCD)
8.   Light Emitting Diode (LED), variable colours
9.   H-bridge (IC L293D)
10. 5V voltage regulator
11. 12V 1A adapter
12. DC jack for adapter

Week 2

For the construction of mechanical parts, I have consult with the 3rd party person, which is Mr. Fitri that has specialization doing steel works.
He ask for duration to designing the mechanical parts into AutoCAD (Computer Aided Design) for 2~3 week(s).
I agreed to deal with him by conditions to follow the design of the sketch.

Degree Semester 2, Week 1

For this week, I have sketch the mechanical structure for KJT device.
It is consists of bearing, screw shaft, ball nut, hinge, guiding set, and others.
All were made from mild steel because it is to reduce cost as to achieve the main purpose for this project.
I have measured all the length of leg parts for common people.
By referring to measurement that has been done, the first sketch was to shown the basic concept for leg movement or motion during treatment.
The second sketch is the re-improved sketch after doing some discussion with supervisor.
