The Components

Assalamualaikum w.b.t

So for this entry I will explained about the components that I used:

• Roboduino Romeo

Romeo is an All-in-One microcontroller especially designed for robotics application. Benefit from Arduino open source platform, it is supported by thousands of open source codes, and can be easily expanded with most Arduino Shields. The integrated 2 way DC motor driver and wireless socket gives a much easier way to start your robotic project.

• Ultrasonic Sensor URM37 V3.2

This sensor is perfect for any number of applications that require you to perform measurements between moving or stationary objects. Naturally, robotics applications are very popular but you'll also find this product to be useful in security systems or as an infrared replacement if so desired. Sensor measures distance using sonar; an ultrasonic (well above human hearing) pulse is transmitted from the unit and distance-to-target is determined by measuring the time required for the echo return.

The URM37 V3.2 Ultrasonic Sensor uses an industrial level AVR processor as the main processing unit. It comes with a temperature sensor which is unique in its class. The sensor has unique three output mode (PWM, RS232 or TTL) which let it easy to adapt to most devices and applications. The sensor provides one channel servo control output which can be used for sweep function.

• Rover 5 Tank Chasis (DF055)

Rover 5 is a new breed of tracked robot chassis designed specifically for students and hobbyist. Unlike conventional tracked chassis’s the clearance can be adjusted by rotating the gearboxes in 5-degree increments. “Stretchy” rubber treads maintain tension as the clearance is raised.

Inside of the chassis are 4 noise suppression coils at the bottom and a battery holder that accepts 6x AA batteries (not included). It is recommended to use NiMh batteries as they last longer and have a higher current output than Alkaline batteries.

Each gearbox has an 87:1 ratio. The chassis can be upgraded to include four motors and encoders making it ideal for mecanum wheels.

Part 4 (week 4)

Assalamualaikum w.b.t

Its been a month already. After had several discussion with Madam Sabrina and do some research. Finally, I got the ideas for my project.

the idea.

This is called Guide Cane. It provide blind or visually impaired pedestrians with the several abilities. Such as:

• safe and fast navigation among obstacle
• position determination and
• guidance

* please be note that, this is the idea/example. Not the real one.. :) for the real one I will upgrade two or three spec into the what my advisor and I was discussed.*

Part 3 (week 3)

Assalamualaikum w.b.t

Alhamdulilah, starting for this week I had started draft my final year project proposal. So, for this proposal I need to completely explained about my final year project and the flow of the project. How its function, the cost of the project and my work plan timetable to completed the project. So far, I had drafted about 60%.

block diagram sketching.

flow chart of the program to make the prototype works.

roughly estimate the cost.

Part 2 ( week 2)

Assalamualaikum w.b.t

As stated on the previous entry, the first week are mainly about how to kickstart the FYP. On this week there will be another FYP briefing. The agenda in this second briefing the FYP coordinator will explain to us about the proposal and the presentation session.

Alhamdulilah, for my final year project, I had selected Madam Sabrina as my advisor. after discussing with Madam Sabrina, I had decided to do "ultrasonic path planning for the blind person".

The goal of this research is to develop a wearable tool that assists the blind person to accomplish his local navigation tasks. It consists of a sensory systems controlled by the user. In order to give the blind person freedom of movement, he/she must be able to control the focus of attention of the sensory system. This project designed to aid visually impaired or blind people to detect,identify and avoid obstacle on their way and assists in finding their way to a specific target.
