Individual Reflection- Calvin Chiu


            ME 250 was definitely one of the more interesting classes that I have taken at The University of Michigan thus far. It was the first class that allowed me to take advantage of real design and manufacturing, which is something that I have always been fond of since a little child. If I had to describe design and manufacturing (in general), I would say that it all boils down to creativity, time management, and simplicity.
            The design aspect of the course caught me off guard because I have never used any sort of computer-aided design modeling in my life before, so using SolidWorks was a change for me. It really tests your ability to creatively come up with an idea that can physically be manufactured, as opposed to a wild one that isn’t exactly feasible. Then, taking those ideas and refining them down to modules was something else that was new to me. I had never done this before so being able to do so now proved a worthy experience for me.
            Manufacturing parts was also a new experience for me. We learned how to use most of the machines in the Mechanical Engineering Machine Shop, and then we were allowed to use them to manufacture our own parts. Manufacturing our own parts made me realize that designing a part isn’t about how complex a part is, but rather about how efficient you can be with the simplest design. I learned that simplicity is key because the more complex a part is, the more ways it can malfunction and fail.
            Teamwork on a project like this was entirely new to me. I feel like I definitely benefited from this course because it taught me valuable lessons in regards to being a part of a team. Everyone has a shared responsibility, so everyone is expected to carry his or her own weight throughout the project. As far as time management goes, this course showed me that working around peoples’ schedules is extremely tough because everybody has different things going on at different times. It is extremely important to organize set meeting dates every week as opposed to winging it every week. Our team had issues with meetings at first, but once we laid the hammer down and organized set times, we flowed a lot better towards the end (except for the actual end).
            The end of the course proved to be one of the busiest time crunches I have ever experienced. There was just too much work to be done in too short of a time, but we somehow managed to complete our robot.
            To be honest, there are too many ways in which this course can be improved. First of all, the task of having an inexperienced team design a robot and manufacture it from scratch within 3 months is just too tough to be done (Unless the robot design is very simple and requires little work). There really isn’t any way to make this aspect of it easier. Also, a lot of the lectures proved useless to me, especially the ones about hole sizing and etc. The information provided to us was just too difficult to absorb mainly because I feel as if we had no basis to build the information off of. It was just free-floating information, so as a result, I did not retain much of it. A lot of the lessons I learned were through experience, not lecture information. Also, some deadlines were too ridiculous. For example, one of the final Milestone assignments where we had to go from having 50% of our MCM’s done to nearly 100% of our MCM’s done over break (within 2 working days) was absolutely ridiculous. The grading for these Milestones proved to be too harsh, so I feel as if these assignments should either be worth less, or should be omitted entirely. On top of that, the shop times weren’t very convenient for our team (and many others as far as I know). The shop should definitely be open later because a lot of people still have class during current peak machining times, and as a result a lot of teams don’t get to register for shop time because of it.
            Personally, there is a lot that I could have done better to improve my performance on this team. For one, I should have studied a little harder for the midterm. Although I feel as if the time constraint on the midterm was inane, there is much more I could have reviewed prior to taking it. Also, I should have managed my time better for team meetings; that definitely would have made a difference. There are also other ways I could have improved my score but were not under my discretion. If we had later shop times, then I could have made more towards the beginning because my schedule often didn’t free up until after 6 or 7 on most days (4 out of 5 weekdays). I would highly suggest that any student who plans on taking this course should reconsider his or her schedule before committing to this class. For a 200 level course this class was definitely too much of a time commitment.
