26/01/2018: Prototype building and completion

This week, I made huge progress in the building process of the prototype of my leg. Initially, my first attempt to assemble a prototype of the leg failed. The structure I used was too weak and it could not hold the weight of the motor. In addition, it was separated into different pieces I had to glue together, making it very hard to assemble. It was also not very practical, as many pieces surrounding the motor were to be fixed permanently onto the leg structure. This would have been problematic if a change of motor was required, as I would have to strip these pieces away in order to access them. As a result, I decided to change my design. In my second attempt, I simplified the process with which the wood pieces were assembled by simply attaching them together with screws. It proved to be effective and yet simple. Once this problem was fixes, I moved on to attach the leg to the structure. At first, progress was slow, as I was not very accustomed to work with small pieces and screws. However, I managed to accelerate the pace once I got used to it and I was able to finish the assembly the majority of the leg structure pieces. In future classes, I plan in adding the motors and in linking them to the arduino and motor shields. I will then test the leg's capacity when powered by a motor. Once that is done, I plan in designing the foot and the body. So far, I am very satisfied with the progress of my project and I look forward for the completion of my new Walker
