Schedule and WBS
A significant tool that we used in our project was our Projectlibre schedule. This allowed us to list all of the tasks that we had to do on this project and plan deadlines. As the project went on we could see where we stood in terms of completion date. A copy of our schedule is seen below.
Above is the final schedule for the RoSco. The tasks that were of concern for us were the 3D printed parts and the PCB layout. We were able to send the 3D printed parts out fairly early but there were a lot of problems with the prints. It would have been beneficial to get our 3D printed parts early so that we could have a lot of time to catch some of our design flaws. However, that is not the way things go sometimes. There were a lot of problems with the 3D printers that we were using because they were printing bad parts. This ultimately had a big effect on our project because we got our parts too late to make changes to our rover. Another area of concern was our PCB. We cut it very close when we sent it out. Our PCB was sent out on the 20th of November and arrived two weeks later. When we soldered all the parts on the PCB everything worked but if it did not work, we would not have had time to fix the problem and get a new PCB. All in all, we moved things along very well in this project but got punished for our manufacturing mistakes.
Mid-way through the semester we had to change around our project positions which made our tasks a little bit unclear in terms of who does what. Below is a final work breakdown structure.
In the above diagram it shows our work breakdown structure. There was a change in the project manager position when Todd Cook moved to Electronics division while Gary Fong and Will McKinney decided to co-project manage. Todd’s was now in charge of the PCB wiring and layout. Youssef Al-shanti was in mission systems and test.
Youssef was in charge of most of the coding in this project which included the code for the servos, motors, control panel design, and the bluetooth.
Will McKinney started helping Gary with some solidworks design because with the switch, Will’s tasks went down and Gary’s increased. With Will helping Gary with some of the 3D design, it would even the load. Along with the 3D design, Will conducted multiple experiments, built parts for our prototype and worked on the schedule.
Gary Fong worked long hours on the 3D modeling of the wheels, brackets and tread. This was a new program for him to learn and he was able to pick it up very quickly. Gary also conducted a trade-off study along with tracking costs.
