This week, I met with David to come up with a plan to make my walker more efficient. One of the major issues of my robot was that it was too heavy, which caused the legs to bend under the enormous pressure. Furthermore, the motors I used were not powerful enough to propel such a heavy robot. Hence, David suggested that I should redesign some parts of the robot in order to reduce weight and to improve on a number of other problems. In addition, David also suggested that I should order a number of electronic parts that would be vital to the functionality of my walker. For instance, he suggested that I should use something to synchronize all of the motors to work at the same time and pointed out that I should use a much lighter battery pack. After this meeting, I went on to work on the new design of the body. In this iteration, I implemented several concepts David suggested, such as the fact that I should cut out as much material from the solid surfaces as possible in order to reduce weight. Furthermore, I also implemented a number of design choices of my own, including the notches I plan to use to fit the robot together. Sadly, I did not have enough time to cut and test out the new body. Hence, my goal next week would be to cut out the new body and to make changes according to the issues that may appear.
