Foto Pusat Pengajian Kejuruteraan Kelautan, UMT dari Udara

Standard

Pagi tadi dalam jam 10.20am, saya dan Master’s degree student saya, Israr telah meluangkan masa untuk menjalankan maiden flight (penerbangan pertama) quadrotor drone yang kami develop sejak dari 2012 (TPM grant, UMT). Sesi berjalan lancar dalam keadaan angin yang tidak terlalu laju (mungkin next time saya perlu bawa anemometer untuk mengukur kelajuan angin).

Bangunan Pusat Pengajian Kejuruteraan Kelautan ini mempunyai 6 tingkat dengan ketinggian 24 meter. Oleh yang demikian, secara kasarnya kita boleh menganggarkan ketinggian penerbangan ini adalah setinggi +- 40 meter.

Spesifikasi quadrotor drone yang kami gunakan adalah seperti berikut:
1. Emax Brushless Motor 2213-935 KV
2. Emax 25A Electronic Speed Controller (ESC)
3. Emax 1045 propellers
4. Ardupilot Mega Flight Controller (APM) 2.0 (firmware V 3.15)
5. LiPo battery 2200 mAH
6. Frame X-type, 400 mm
7. Camera: GoPro Hero 3

Event: Fundamentals and Building of Quadrotor Drone Bersama UMT-Petrosains

Pada 3 Julai yang lepas, saya telah menyampaikan sebuah bengkel latihan yang diberi nama Fundamentals and Building of Quadrotor Drone. Event ini telah dijalankan di Universiti Malaysia Terengganu, yang mana ia dihadiri oleh jemputan dari Petrosains dan ahli-ahli kumpulan penyelidikan saya iaitu Ocean Robotics & Optimization Group.

Bengkel Latihan ini dipecahkan kepada beberapa bahagian, iaitu; pengenalan asas elektronik & robotik, pengenalan kepada konsep quadrotor drone dan amali pemasangan quadrotor drone.

Bengkel amali ini adalah yang pertama seumpamanya diadakan di Universiti Malaysia Terengganu, dan mungkin pertama di Malaysia :-)

Setiap peserta diberikan peluang untuk menerbangkan sendiri model drone dan juga diberikan sijil penyertaan.

Ucapan terima kasih saya sampaikan kepada para peserta, iaitu; Petrosains Outreach Programmes Department Director, En Kamaruddin Kassim (KK), Cik Nurhidayah Nordin (Hani), En. Johan Shah Arif (Joe), Cik Tengku Hafidah Tengku Hussian, En. Ahmad Israr Ihsan Mainong dan Dr. Syibrah di atas penglibatan mereka di dalam bengkel latihan ini.

InsyaAllah, bengkel ini akan diperluaskan lagi mengikut demand kepada peserta-peserta bermula dari peringkat lepasan SPM, universiti dan masyarakat umum.

Di dalam wiki Ardurover, ada diterangkan berkenaan dengan sambungan diantara Receiver (RX) dan RC Input pada APM board. Akan tetapi, di dalam gambarajahnya, ia tidak menerangkan dengan jelas, yang mana satu RX output dari segi Throttle, Rudder dan Auto mode. Bagi mereka yang memerlukan gambarajah grafik, sila rujuk gambar di bawah untuk bantuan.

Lessons Learned from Industrial Visit 2014

This year I’ve managed to spend my time with some companies for the purpose of formal annual industrial visit, arranged by the university. Last year the most notable company was North Port Berhad (they would like to see Malaysia to develop its own underwater robots and systems). This year I manage to sat down with important people from Katsu Engineering, KJB Sdn Bhd, Sinco Automasi, TGS Maritime Technology and Malaysia Marine Heavy Engineering (MMHE).

Based from the meetings, there are some important lessons that I would like to note:

1- Malaysia used to be the best marine builders (ship, coastal & offshore) in the early 1990′s to 2000. Nowadays, the better services come from Singaporean companies. This is due to the advancement of technologies, the increase of efficiency in sourcing and innovative business strategies. Our undergraduates in School of Ocean Engineering in UMT should be exposed with these knowledge through case studies and practical research in order to match with such capabilities offered by our neighbour.

2- With that said, we should realize that technologies will come and go. However, experiences are things that could not be bought, and needed to be accumulated with time. Therefore, an age well spent is very important to the young engineers.

3- Age itself is something that could not be bought, but a young company can bring in experienced engineers (age 55 and above, post-retirement age) to come and mentor the operational and business aspects. This will introduce the use of best practices, especially regarding the importance of time-keeping, ledger records, work documentations and the dynamics of pricing.

4- Today, a young company could have a mentor, but how about the future? During the establishment of a young company, a system needs to be developed in such sense that if the mentor is not available, the company shall be able to steer itself automatically and maintaining her pace and directions. Therefore the need to have proper web-based data records, marketings, lead and sales in and out, expenditures and closures are critical.

5- Finally, a company should have some modes/strategies for it to at least, survive. It should have long-term vision for 20-40 years ahead in order to develop a culture of success.
