Team Vision for Subsystem Level Build & Test Phase
According to the following project plan, the main goals for this phase were to have all mechanical components manufactured, along with a detailed electrical diagram drafted and high lead-time electrical parts ordered. The goal for software at this point in time was to begin debugging of the data collection program in Labview, as well as preliminary ideation of the methods of data analysis.
MechanicalThe mechanical design was made to function in two different set-ups; the first is mounted directly to the optical breadboard to begin preliminary testing without adjusting any inputs. The second setup will incorporate adjustable angular and positional input as well as allow for ease of exchanging the couplings by using the slide. All parts are complete for the first set up, and one machined part and two 3D prints are needed to set up the later design. We expect to be complete with the final parts by 10/10 and anticipate there may be small adjustments made to the mechanical design to address any issues we may run into in terms of functionality.

The electrical design work and status was compiled into the following word document:
Data analysis will be conducted differently via different software programs. A DSP analysis will be carried out by Matlab (using the included dsp toolbox), while more general control charts and other statistical analyses will be carried out by Minitab. The essential analysis will be determining the differences between the input and output encoder values without a coupling inserted into the system. These differences will define the error due to the fixture.
Risk and Problem Tracking
All risks tracked remained unchanged throughout this phase:
Plans for next phase
As noted in the project plan above, the next steps for the upcoming phase are to complete manufacture and assembly of the mechanical subsystem, as well as the electrical subsystem. Following the combination of mechanical and electrical subsystems together will be a systems error test, set up to ensure the integrity of the test fixture data without any coupling error incorporated.
