WEEK 13 FYP 2

Title of activity:

TROUBLE SHOOTING FORMS

Title: ROBOTIC WHEELCHAIR FOR SPECIALIZE OPERATIONS

Date started: 10.10.2012

Date ended: 12.10.2012

Time taken: 2 days

Equipment: Digital Multimeter, supply and jumper

Observation / information: LED (indicator) at motor driver (reclining part) circuit not turns ON

STEP:

1.      ON supply; the LCD display is display the stage of reset condition.

2.      Press switch forward right; the wheelchair is move forward right and indicator is ON.

3.      Press switch recline leg’s part forward; indicator not turn on but the leg’s part is not recline.

4.       Press switch recline body’s part forward; indicator not turn on but the body’s part is not recline.

5.      Check input voltage at indicator and noted the value of voltage. The voltage is 0V then checks the value of other component and check their connection.

6.      OFF supply; check the connection of supply and circuit wiring. Find wrong connections supply from the input to the motor driver circuit. Repair the wiring and check again the connection.

RESULT: Since the supply is connected to the motor driver circuit. Therefore, the indicator at motor driver circuit is turns ON and the leg and body’s part is reclined.

WEEK 8 FYP 2

 

Title of activity:

Combine the hardware of mechanical part with the circuit programming.

OBJECTIVES:

To make the prototype operate with the main program.

1. use the screw and screw drill.

2. make a hole at base by using screw drill.

3. screw the circuit to the base.

 ANALYSIS:

Conclusion:

it will be great if can put the circuit in upper seat but the prototype is small so it's can't. But if upgraded it can be change ;)

WEEK 7 FYP 2

Title of activity:

 Make the programming by using assembly language and pic 16F877A

OBJECTIVES:

To make sure the prototype can function by using the instruction in programming.

CONTENT/ PROCEDURE:

1. Do the programming based on process of flowchart and block diagram.

ANALYSIS:

By using this pic and the function of each pin the prototype can function very well, insyaALLAH. PIC is a family of modified Harvard architecture microcontrollers made by Microchip Technology, the name PIC initially referred to "Peripheral Interface Controller". PICs are popular with both industrial developers and hobbyists alike due to their low cost, wide availability, large user base, extensive collection of application notes, availability of low cost or free development tools, and serial programming (and re-programming with flash memory) capability. We used this pic in our circuit to control the wheelchair.

CONCLUSION:

The hardware or the mechanical part cannot function if the programming have the problem. Pic is like the main brain for this project.

Title of activity:

Put the component at PCB for each circuit.

CONTENT/ PROCEDURE:

1. Make the design where to put the component and the connection.

2. using the solder to connect the component.

3. use the multimeter to check the connection.

ANALYSIS:

below is the circuit of driver motor circuit that after solder.

below is the circuit that combine with lcd panel and switch

CONCLUSION:

When doing this, must make sure the connection is okay. therefore the output can be okay.

WEEK 5 FYP 2

Proposing the circuit for etching in PCB board. 

OBJECTIVES:

Showing the circuit for etching purpose.

CONTENT/PROCEDURE:

Here, I would like to present the circuit drawn after the schematic circuit. This is where I should print on the PCB board.

ANALYSIS:

this layout for ecthing is the motor driver Circuit.

below is the pcb layout for PIC circuit for this project.

CONCLUSION:

by using this etching for PCB it is more easy to design the circuit and to solder the circuit. it ease our problem and more easy.

ANALYSIS:

 do you think what it will be? can you imagine my prototype?

this is my prototype after i redo many time due to mechanical problem.

CONCLUSION:

from doing this mechanical part, the design is the important thing in this part. make sure all the material, size, design is suitable and fix with objective in this project.

WEEK 3 FYP 2

Title of activity:

Block diagram and flow chart

Objectives:

To explain clearly about process of this project

Content/Procedure: 

1. list all the input and output.
2. State the process of the project.

ANALYSIS

 The switch is the input of this project. The users give instruction by using this switch. Then the input from the switch is fed to PIC micro controller. The pic microcontroller will control the program and give instruction to the DC motor control which is the H bridge circuit. This make the dc motor get instruction and perform the results in wheelchair which we can see the results in mechanical performance. PIC that will use in this project is PIC 16F877A that working like a brain to receive the input from the switch and give instruction to motor to operate. It also produces output to the blinking of Led and LCD’s display.

The flowchart is discussed about the whole of process of project. This project will program that this prototype will operate when get command from the user by switch. Then the command from the user is the input for pic program and will produce output which is LCD display, red and green led that act as indicator, the movement of wheel and reclining’s part.

 CONCLUSION

The blcok diagram and flow chart must correct so the flow or process this project can be smooth. InsyaAllah.

WEEK 1 FYP 2

Title of activity:

Research on the circuit

Objectives:

To make a clearer vision on what circuit that i will be use.

Content/Procedure: 

1. Since this week is the first week of new semester, I got a lot of issue with my time table. Hence, I don't have too much time to meet my advisor. 

2. But, although I got a lot of things to be done by week 1, I still make a research on schematic circuit through the internet, reference book at library and also asking to my friends. 

3. Based on my research i need to find the PIC 16F877A circuit which is can control my project and motor driver circuit to control direction of motor. Circuit of PIC i use the common circuit but i add on some switch and lcd panel in the circuit as input and output for this project.

4. Then i find H-bridge circuit that use L298  as my ic motor driver and i need to construct the circuit based on data sheet that i got from the internet at website solarbotic.

ANALYSIS:

This circuit of motor driver L298 is important to control the direction of motor for movement of wheel and the movement of reclining part.  I choose, the stage of motor operated can see by the blinking LED as an indicator in this project. I try stimulate in multism and look the output before use in my project. after that i know this circuit is suitable with my project.

All the program will be setting in Proteus by using this schematic that contain PIC circuit to run the program.  From the beginning there have mention about the wheelchair need the instruction from the user to operate the wheelchair. Therefore the programming is needed in this project. The microcontroller is using to program the project by using assembly language. The project is start when the user gives their instruction using switch whether to move the wheelchair or to recline the wheelchair. Then the programming is needed to run the dc motor. The dc motor is controlled by using H bridge circuit like i said before.

Conclusion:

The simulation of this circuit is going well, Alhamdulillah so i will use this circuit in my project.
