Though my research was about prosthetic arm, I didn't want to focus solely on the arm, I also wanted to consider the elbow and hand loss and the need for an artificial limb to replace them. My sketches consist of two sketches of prosthetic arms, two of elbows and two of hands, total up altogether is 6 sketches (just nice!).
My sketches were merely just different designs of prosthetic limbs, and I didn't really know what else to draw as my sketches than different designs. I try to be creative yet at the same time try out different colour on different designs. Black and white seems a bit too common for me, but I still use them because they look nice with other colours (take blue for example). I also made them look metallic or robotic. When I did my 3D model, I took reference from my very first sketch of the prosthetic arm. I also tried making the artificial limbs pose in different ways like a peace sign or waving in a way to show that people can move their artificial limbs like their normal limbs. An important consideration in the design and fabrication of a limb prosthesis is the type of material used for its construction. Interface materials will influence the comfort of the socket. Structural materials will affect the strength and weight of the overall prosthesis. The prosthetist has a vast array of materials to choose from in designing the optimal prosthesis for a particular individual. Plastic Polymer Laminates (Thermosets)

We were supposed to make the 3D model in sketchup, but i don't think it was possible because there were no 3D models that we could use (or reference) from the 3D warehouse, thus we had to do it in real life. Since my my research and limb is the arm, I had to make a prosthetic arm. Materials used:
Procedure: So first, I had to make the palm of the hand. Next I needed to make the fingers. I wanted to make it look fake/robotic so I used another colour clay to make the fingers look separated. I stuck the wires in the fingers and on to the top of the palm. Next was the arm (or half of the arm). I cut a manila card into half, rolled one half and tape it together. Next I wrapped it around aluminium foil to make it look metallic and all I had to do to finish my work was sticking the hand to the arm. But because the top part had a hole, I had to use clay and cover it up to use as a support and not to mention I also used wires to hold the hand as well. I just had to tape them to the sides of the manila card. And ta-daaaa! It's done! Reflection: The 3D model wasn't hard to do, I kinda enjoyed making it but I think I could've have wires to make the shape and later cover it with clay or maybe paper mache. Since the clay is heavier than the manila card, I'm still surprise it could stand without falling. I had encountered problems during the limb making process. I had difficulty with the wires where some were too short, they would fall off or they would come out when I push them into the clay. Another problem was the fingers. Since they're clay made, their not stuck very well to the palm even with the wires there, it's... fragile. The fingers can come off easily if or sometimes bent and I had to take all of them out to avoid any more harm and later stick them back inside. Overall, I'm quite proud of my model, even though it's not the best look arm, I'm still happy. Next time when we're doing real life model making like this, I need to think carefully and consider some other possible ways to make this and hopefully easier ways too. References:

There are lots of people who have missing limbs. They could've lost their arms in many ways, by disease or an accident and had to amputate it or they could have been born with it due to passing down of genes. Some have said that they weren't comfortable when they first tried or wore artificial limbs (prosthetic arms). Today, I'll be focusing on the arm only and my goal is to create a comfortable ad efficient prosthetic arm for these disabled people. In a website, Linda Bannon was born without arms due to a "hereditary condition called Holt-Oram syndrome or heart-hand syndrome". When she was young, Linda had tried prosthetic arms but said it made her uncomfortable. Linda taught herself how to do everyday mudane chores (which was quite a challenge for her). She's married and had a son called Timmy, who like her, is born without arms. "The doctors had told Lina there was a 50% chance their child would be born like her". This supports the hereditary condition Linda had and passed it onto her child.
