Hi all,

It will be my turn (Leonard) to update the blog.
These are the updates for the project so far.

At last, the carbon fiber plates have arrived on tuesday 6/05/2014. The long wait has been over. Now, it is time to construct our very own quadrojak.  All the components that are required for the construction, have been placed on the table so that it will be much easier for the rest of the members to build the structure. Looking from figure 1, the four longer carbon fiber tubes will be used and be mounted on the quadrojak structure. They are used to provide mounting for the crash cage that will be constructed at a later time

The four big motors will be used for the rotation of the propellers. Each of them will be placed at the end of each support arm of the quadrojak.

Figure2: Motors To Be Used

 For the construction of the quadrojak, the system engineer aka Angus, the control engineer aka Jonathan Daryl and the structural engineer aka Edwin were all involved. Working hand in hand together, they have to ensure that the wirings for the control system are connected correctly, the carbon fiber tubes are tightened into position, the parts of the structures are joined appropriately. Here are some pictures  of the construction process.

 After a tiring day working on the quadrojak, with a big smiles on their faces, they are happy with the final product of the quadrojak.

Even though the main structure of the rojak has been completed, they have to test out on the control system to see if the motors are able to be powered up so that they can allow the propellers to rotate. This is the result that is shown in the video after they have test out on their control system. Note that in the video, the bottom part of the crash cage has been built unto the quadrojak's structure.

Hearing from the sounds of the motors that are being generated, it should be fast enough to provide the right amount of thrust to lift up the system.The construction of the whole crash cage is not complete yet so the bottom part of the crash cage will be removed from the quadrojak first. In order to protect the propellers of the quadrojak during flight testing, a PVC tubing structure was being constructed around the quadrojak.

Any advancements such as flight testings will be postponed to a later date as we will be focusing on their individual report, presentation and poster for FYP submission. After the FYP submission, we will also be preparing for their exams. Do look forward to hear from us very soon when everything is completed. Thank you very much!
