Hi, my name is Christian de Weck, and I created the T-pack. This is my evocative image and it shows a man frustrated over his broken down car. When building or repairing anything away from a workshop (roadside repair for example), it can be difficult to organize all the tools you may need in a toolbox, and it can be hard to come back to your work after you've found the right tool. read the problem and solution slide. This is my first precedent and it shows a concept drawing back attachable robotic arms. I really liked the look and the position of the robotic arms on the person's back and it seemed similar to my idea. My next precedent is a regular backpack because i wanted to incorporate all the standard straps  and make it feel like a backpack. My last precedent is a tool pegboard and I used this because it seemed like a very good and efficient way to hold tools on one plain..This is my first sketch and concept drawing of my project and I essentially Drew the image in a first and third person view. I wanted the tool sheet to be able to attach to your back when you are mobile, but when you are fixing something I wanted it to be right in front of you within reaching distance. The second sketch is a top view of how the pack would function and I wanted one giant arm that could swing out and bring the tool sheet in front of you. After that I started my first iteration out of card board and it was basically just two cardboard sheets connected to  by one arm. There were a few problems with this prototype the first of which was that when the sheet was swung out it was very bulky and hard to move in. The board was also too close to my body and was not able to be moved. In my second iteration. I changed having just one big sheet of tools to four small tool arms that could slide in and out on a track. This allowed me to move very easily and adjust the arm length from my body but there was now concern that the tiny arms on the pack could not hold many tools, negating the point. In my next iteration I changed that by using two larger tool arms that came out on each side of the person. This was a great compromise between mobility and storage and I used this prototype as a template for my final version. After this I designed a curved back piece in rhino which I then cover with foam and attached it to a copy of my previous prototype to make a fully functional and wearable backpack. This is the my construction Diagram and it shows how the entire pack is put together. This is my functional Diagram and as you can see it shows how the pack works with it's arms. These a some of my final images and these first two is just the pack in our Photo Booth. this is image shows me waring the pack and bringing out the arms. Thank you.
