This week, I tried to improve on the existing iteration of my walker. I tried to reverse the positioning of the feet in order to give it more stability, but it had the opposite of the wanted effect. I also tried to replace the two piece body with one that is composed of only one section. While it did allow for some weight loss, it was insufficient to solve the core problems. In addition to my inability to improve the performance of the walker, I had issues with the electronic parts of the project. For some unknown reason, even if both the arduino and the motor shield were connected to the battery, the legs would not move. Hence, I also spent quite some time on trying to figure this out, which meant that I did not possess enough time to complete the major changes. I was able to start work on the remodeling the whole design, however, and to print out some pieces that I will need in the future. The new iteration would have some major differences when compared to its predecessor, as it would have 6 legs instead of 4, and all of the motors would power a set of gears rather than individual legs. The addition of new legs is meant to provide more stability when walking and the gears were added in order to allow a certain level of coordination between the 4 motors. Next week, I plan in completing these changes and to start working in my diagrams and presentations.
