The most recent meeting : 3/10/2009 sat

In this meeting we decided to work stuff in parallel ( we mean the two projects ), however our main focus was on the modeling of the " grass cutter" and the mechanical design

we come up with the last modeling which has been shown in here ,,,

the group members who were there in that meeting:

1- Mahmood Alkhudary ( 0515773 ) absent (excuse)

2- Mahmudur Rahman ( 0511331 ) absent ( no excuse)

3- Imama Ushama ( 0535421 ) absent (excuse)

4- Shawgi Younis ( 0526527 ) present

5- Saleh Ashmil ( 0415921) present

2009-09-01T20:00:00.000-07:00

A new change in layout, organization and work.

2009-08-31T17:20:00.000-07:00

A proper Functional Decomposition is drawn. It has to be checked with the lecturer.

The diagram is as follows:

FUNCTIONAL DECOMPOSITION

NEXT STEP

As stated earlier,

Morphological chart completed

the alternatives will be drawn,

pugh graph completed

Progress report completed

2009-08-31T16:49:00.000-07:00

To this moment, progress is very slow. I hope the team will buckle up and move faster. A drawing of functional decomposition was completed. The HOQ is nearly complete but there are some problems drawing it. The morphological chart is at the moment being sent around for updates. A meeting will be called to finalise it. Once that is done, a pugh graph will be drawn and the respective alternative will be chosen.

These are the follwong documents which can be seen. It's hard to upload it here, thats why I have uploaded it in another location.

a)Functional Decomposition

(this is just a rough)

b)Morphological Chart (modified)

c) Update on paper

Thank You

Needs only (done by Imama)


1	Small input should be given	Good
2	Parts should be replaceable easily	Should
3	Be safe for people as well as pets	Good
4	Height of grass to be cut- moderate	Must
5	Grass to be cut should follow the	Must
6	shape of ground	Must
7	Not produce harmful wastes (like burnt petrol)	Should
8	Expected to stop on its own if there is any blockade	Good
9	It is expected to be small	Good
10	Cutter should be able to move fast	Good
11	Weight is light	Nice
12	Expected to stay on grass all time	Should
13	Temperature remains cool	Nice
14	Less noise	Should
15	Less damage expected	Should
16	Cheap to repair	Should

Metric and Values (Incomplete) (done by Imama)

The new Metric values can be taken from the document at the top of the page

We have proceeded to Concept Generalisation and at the moment coming u with the functional deployment and morphological chart. We have yet to upload the that meeting's minutes and after preparing for the midterm, it has been realised that certain things are not done properly. Thats why we have a delay. Inshallah we will update the complete PDS as soon as possible.
Thank You,

The Intelligent Grass Cutter is the title

The WBS, LRC and PCM, GANNT CHART and team calendar will be uploaded shortly.

At the moment these are the questions that we want to ask our customers. After considerations, the best 6 has been chosen.

1) How fast do you expect the grass cutter to cut the grass?

2) What is said to be the average height of grass to be cut?
3) If your garden is not flat, would you want your grass to hide it, i.e. make it look like a flat ground or have the same shape of the ground (slightly up and down)?
4)Do you mind if the cutter has moderate sound (noise)?
5)How much will you invest in an intelligent grass cutter?
6) Do you expect your cutter to stop working when it goes out of field or should it stop at the place that it has started?

Progress is slow but we will catch up with our deadlines.

The next step is to interview them in a day's time and interpret the results.

The purpose of this blog is to update the team as well as the lecturer about our Mechatronics System Design (MSD) Project. Every single update will be done here.

Thank You
