Team Vision for MSD II

Vision for Subsystem Build and Test Phase

The scope of this phase encompassed a few key tasks that needed to be accomplished by the team prior to building. Due to the long period of time between MSD I and MSD II, it was important for the team to conduct a meeting to ensure a seamless transition from design to construction. From there, the main objective was to have all the test plan written in order to account for all the engineering requirements provided by the customer. Much like the previous phases, the team split the test plans into the Mechanical (system integration) side and the Electrical side. There were a total of 22 test plans to be written, 8 ME test plans and 14 EE test plans.

Current Vision for End of MSD II

Complete the project. By the end of MSD II, the team wants a have a functional temperature acquisition system that can be integrated into Biomass' BGR in order to record useful data. Additionally, the team would like to present their results at ImagineRIT.
