And the build being...

We are all getting bored of the paper works, equations and theories. Finally moving on from paper warriors to the fabrication of Quad Rojak. Before anything tangible can happen, there are a little more paper works to be conquered. While waiting the the shipment of raw materials, we should proudly present to you our concepts through the posters 

From the System Level Design (SysLeD), Angus, my point of view. The parameters of Quad Rojak had been established after numerous experiment with in house design and 3D printed equipments.

From the Control System Design, JD, point of view. The configuration and programming of the Microprocessor and Electronic speed controller had also been decided. Meanwhile, JD will use his understanding of the new Microprocessor and attempt to fly the existing quad copter Flame Wheel 450 (the one we disassemble during the first week).

Up next we have Edwin Goh who is in charge of the structure. Material selected are mainly carbon fiber and some aluminium. We knew that Edwin had made the right choice for material when he mentioned that it was harder to cut carbon fiber rod than metal rod. Before making any major decision in the detail design Edwin intended to use acrylic and 3D printing to build our first Quad Rojak prototype.

Jeremy Yeo the Battery loader designer. After tremendous effort and time spending on researching, computer aided design (CAD) software and 3D printing Jeremy was finally able to come out with all the require components down to the smallest details (number of teeth in the rack and pinion).

It is now Wong B.Z turn, he who is in charge of crash protection cage.The material chosen is also mainly carbon fiber and some rubber for connections purposes. Anyone must know that with more protection it is going to weight more on Quad Rojak. Therefore for now, B.Z is still trying to find a balance between protection and weight before the fabrication of crash protection cage can being.

Finally, we have Leonard our terrestrial drive designer. After much discussion with the team, Leonard had decided to change some design features of the current Terrestrial Drive. A very exciting prototype to look forward to, stay tuned folk.

Special Thanks to Jeremy Yeo and Daniel Ng Chi Koon for preparing Spaghetti for the class this week. It was out of goodwill seeing how hard we work for the Quad copter project Jeremy Yeo decided that he should encourage us with home cooked food. Such group mate, heart warming.
