circuit construction...

14 Disember 09

today, we construct the circuit for the wall climbing robot race to operate.
there is 4 circuits that mainly operate in the robot that are Sk40A circuit operation, SC16A circuit, sensor circuit and servo motor circuit. all these 4 circuits is combine into 1 pieces circuit board.

sensor...transmitter and receiver that will used in detection the suction cup on the wall


combination of 4 circuits...

programming robot...

10,11, & 12 Disember 09

for this 3 days, we are concentrating to the study or revision about the programming of the robot. we have already borrow the burner or the UIC00A socket for programming the PIC microcontroller. therefore, for these 3 days, we spend a lot of time in programming the robot. In other means, we try to program the wall climbing robot to do its work, as fast as possible.

UIC00A socket...

the programming cover the movement of servo motor for make the rotation. there is two type of servo motor in this robot, first is the 180 degree servo and second is the 360 degree servo motor. so, we must make the programming for these 2 type of servo motor to applied it to the robot movement.

programming + testing...

more than that, we also make an adjustment or improvement to the robot include its stability, reduce the weight that is very important in this robot and others. about the stage for the robot to move, the progress is 70% finish and we are waiting the perspect material from the supplier to complete the last section of that stage.

stage...

meeting and some problem!

9 Disember 09
today is our first meeting of the Singapore Robotoics Competition(SRG). all the groups that involve in SRG attend this meeting at lecturer room at 11am. all the responsibe lecturer for SRG also attend this meeting to know the progress from all the groups that will participate for SRG. the groups consist of Sumo Robot, Colony Robot and Wall-Climbing Robot.

the first problem that cover during this meeting is that the budget! there is a cancellation from the Presiden of UniKL for not allow all the groups to go for SRG. the reason is that the budget for SRG is over. therefore, the responsibe lecturer for this SRG, Mr Lukman Hakim will discuss again with the Dean of MFI for the confirmation of this problem. so, we need to focus to our project only.

the work for today is that, we continue our revision about all the board that will be used in our wall climbing robot race. in addition, we also research about the suitable optic sensor that will be used in wall-climbing robot. optic sensor is used to sense the exact distance that the suction cup will do its work properly.

MU 3-1 Wolfsburg

Manchester United made it right last night...
3-1 terhasil semalam apabila MU berjaya mengalahkan Wolfsburg.
dengan keadaan skuad yang huru-hara disebabkan ramai cedera, MU masih berjaya untuk menang.


hatrik dari Owen....

revision period...

8 Disember 09

today, we concentrate about the programming of our servo motor. we choose to used the board of SK40A for the programming of servo motor to communicate. actually, we have already used this board last semester when we take the subject of Mechatronics Design Project. after a little discussion with Mdm Siti Khadijah, we choose the SK40A board from Cytron Malaysia for our programming of wall climbing robot race. therefore, today is just for the revision day or a study period for us to understand the function of SK40A board. although we have already know the basic guide to used that board, we still need to renew our knowledge for the convenience of us.

SK40A board with cable...we borrow this board from the technician of MFI.

in addition, we also study the SC16A board that will used to communicate with SK40A board. SC16A board is a 16 channel servo controller that we bought from Jalan Pasar on yesterday. this board also supplied by Cytron Malaysia.

SC16A board...

another work that we have done today is making the joining process of suction cup, servo motor and the part that comes from suction cup for the convenience when the sucking process happen.

Jalan Pasar...

7 Disember 09
I and my partner continue our FYP today after we hold our process about 2 days because of a problem from my partner, he goes back to KT.

today, actually one of our servo was break down a few days before Raya Haji because of its gear was stuck or cannot function as usual. this problem brought us to Jalan Pasar to buy again another servo motor. at first, we want to claim the broken servo motor but that electronic shop can't help us because that servo is broken because of us. we accept it! however, we got what we want and 3 servo motor was bought by us, costs RM 270 (RM 90 each). another device that we bought is 16 channel servo controller that cost us RM 165. therefore, the total we spend today is RM435!

MU 4-0 West Ham

Manchester United got it 4 again...
Scholes, Gibson, Valencia dan ROONEY melengkapkan kemenangan MU mlm tadi.
kemenangan dicapai bermakna MU hanya dipisah dua mata shaja dgn Chelsea.

4 gol dihasilkan smlm!!!

GO GO GO Mancheeeeeeeeeeeeester Uniteeeeeeeeeed....

servo breakdown + claim!

4 Disember 09
welcome to the world of screws!!!

this is the recycle screw, bolts, nuts, and whatever they called as joining material. these world of screws is help us very much in designing and joining all the robot's parts.

for today, the same process happen based on yesterday process that we test our robot in the lab again to know the exact voltage and current that support the weight of robot. the test have already done and the result is need to calculate again because they is a calculation between force of material and the length of our robot. we cut the main body of robot that is aluminium tube to the length of 1feet because the force of material problem. therefore, our robot will smoothly move between section to another section.

this is the new look of our robot...the length is reduce to 1feet only!





below is the video for the testing process in the lab. the maximum voltage that the servo will supplied is 7.2V but we use only 6V voltage combine with the high current to make the robot operate smoothly.

however, the most important is that our servo actually cannot operate smoothly due to the broken of its gear, as we assume only!
and the best thing is we got our first claim that is RM550 for the costs of our budget...

whole day in LAB!!!

3 Disember 09

I have spend the whole day in the Robocon Lab today.
but the result that I and my partner got can be said as successfull.
however, not all parts are success, certain must be check and do it again, again and again!!!

but today, the success part is that we got to build the main body of our project consist of suction cup, servo motor that are joint together with another suction cup and another servo motor. all these material we connect with the 'recycle material' that comes from the Robocon Lab including screws, bolts, nuts, aluminium tube and others.


this is our main body of robot...

the testing have been made to the joining part of suction cup, servo motor together with aluminium tube and the results is successfull!!!









the testing is done and the robot able to support the weight consist of two 6V rechargeable battery....

servo makes me sick....

1 & 2 Disember 09

FYP is still alive with a new intention after Hari Raya Aidiladha that we celebrate a few days ago. for this two days, I and my partner is concentrate to the servo motor. because of this servo motor, our sleep is disturb totally.

at first, the servo motor supplied by technician is not running properly after we demonstrated it.


the need for servo motor is very important because the servo that supplied by the technician is not highly help us due to the lack of specification that cannot be given. we don't know the exact value for the voltage supplied by that servo. the spec is very very important for the construction of a proper suction process combining the application of servo and suction cup.

therefore, we proceed this poblem to Jalan Pasar and all this probem is settle. we bought two type of servo motor that is for 360 degree and 180 degree. we bought two servo motor for each type that cost us RM360 nett. these 4 servo motor is supplied by cytron malaysia. but the most important thing, we got the spec for our servo motor!!!

we have test it after we got it and the result is nearly successfull...



for this two day, we also finish the painting process of our stage that needed by the rules of competition. but the important thing for the stage is to wait for the material (plastic composite/prospek) that we ordered.


FYP!!!!!!!!!

FYP hold...

Tuesday, 24 Nov 09
today, just a revision or some called as a research day for our FYP progress.
this happen because of the some adjustment or replacement method that we need to discuss with the supervisor and co-supervisor.

therefore, today we have a discussion with the supervisor only because our co-supervisor have a work to do.
the replacement include the used of suitable motor to the robot, that is servo motor and the concept of gear. actually, there is a link between the used of servo motor and the concept of gear in giving the proper movement for our wall-climbing robot.

in addition, mr yusman also gave a few input to us for the research of a suitable servo motor to be used to our robot.

so, there is what happen today and we now focus to the HARI RAYA QORBAN that will be celebrate next friday...
and our FYP is HOLD for a few days...

SELAMAT HARI RAYA!

just look around...

Monday,23 Nov 09
not much work we have don't today due to the arranging plan that we want to build again with the supervisor and co-supervisor...
actually, for now we have a difficulty in determining the right solution for the problem that we had...
include the right material to be used, the right method to be apply to the application and the dreaming result that we want to achieve.
today, we had a discussion with the technician only because our supervisor and co-supervisor have a work to do...thanks to Encik Marzukee for his co-operation as a technician!


however,there is a work that we have done today. it is a painting or spraying process to our wall of the stage for our robot to move on properly. this process actually not very important because painting or spraying the wall is just only a guide to know whether the robot used a sensor or not to make it move on....
for the fact, we don't make a sensor to make the robot move on...
and therefore, the spraying process is just to fulfill the requirement for the competition...

we found a new one

Sunday,22 Nov 09

actually, our FYP progress is need to rest because the shortage of some materials.
but the stage is on its way to be settle in a few hours again..section B is a big problem for us because the material is being ordered.
today is a little holiday for us.

the stage or wall...section A and C that is finish!!!

however,we make a new improvement or a new things to our project because we eliminate the old suction cup with the new one..that is bigger and harder than before..we bought it from Cheras after we search it from lelong.com.my...

this is our new suction cup...RM38!


that suction cup manage to support the wall of stage..we experiment it!

MU 3-0 Everton

Kerinduan melihat aksi Manchester United terubat semalam setelah hampir 2 minggu liga EPL bercuti. MU menggunakan sepenuhnya kelebihan bermain di Old Trafford selepas berjaya menumpaskan Everton 3-0. Mu dah naik ke tangga kedua sekarang selepas musuh utama, Arsenal tewas kepada Sunderland 1-0. Gol-gol semalam dijaringkan oleh Fletcher, Carick dan Valencia...


superb dari Fletcher..


slow motion dari Carrick


fired dari Valencia...

stage almost done!

Saturday, 21 Nov 09
stage construction continue again with the work for the postponed work yesterday.
today, all the needed material is provided by the technician except the plastic composite or some called as 'prospect' material for the middle part of the stage. work is very hard today but the technician help us a lot in designing and building the stage as fast as possible.

the machines used in this work are MitreSaw and JigSaw.

these are the section parts from three section that is A,B and C that we have to build for the stage to complete.
the two sections that are A and C is almost complete except the last section that is section B is hold to wait for the material being ordered.

suction cup with 5.25kg

this is an addition to the weight that the suction cup can support.
there is 5kg & above that this suction cup manage to support.
the experiment has been made and the result is calculated that 5.25kg!
after 5.25kg, the suction cup look heavy to support above that value.

2kg....


5.25kg...

shortage become longtage..haha!

Friday, 20 Nov 09
what is means by that longtage...just for kidding!

this day start when we looking for shortage material that is bolt and nut for the construction of stage.
we got it and the frame for that stage is finally being progress.
the bolts and nuts cost us RM15...!




but the stage is secondly postponed due to the lack of materials at the Robocon Lab.
the lack materials are bolts and nuts again, plywood and material that used for joint the frame of stage.

the progress of suction cup is still in its way. the new thing is we add the adhesive glue to the suction cup and solenoid to tighten its together and the result is see below:


the most important things this day is, we are cheated by the chinese hardware for the cost of bolts and nuts. the chinese hardware cost us RM15 for 50 bolts and nuts. but the malay hardware cost us only RM12 for 100 bolts and nuts...so outrageous! however, all the cost we can claim it under the FYP project and Robotics Competition.
