Team Vision for Subsystem Level Build & Test Phase
- Clarify questions and mitigate risks via SME feedback
- Order most, if not all parts
- Finalize BOM
- Begin Preliminary Test Plans
- Update Test Plans & Results
SME FeedbackIn order to better understand labview & controls wiring, (see the Updated Pneumatic System Schematic) the team met with Dr. John Wellin of the Mechanical Engineering department & Dr. George Slack of the Electrical Engineering Department
LabviewDr. Wellin has much experience and understanding with Labview programming, which is the program used for the pneumatic controls. The system will be controlled based off of sensor & manual student inputs. The notes from the meeting minutes with Dr. Wellin are listed below.
Controls WiringSince the team lacked an electrical engineer, or anyone with high levels of electrical engineering experience, input was desired from someone with a much higher understanding than that of any of our team members. The main purpose of the meeting with Dr. Slack was to verify the feasibility of the current controls design and to gain ideas for part purchases.
Special thanks to Dr. Wellin & Dr. Slack for their time and feedback on this subject
Ordered / Acquired PartsDuring this phase, calculations required to confirm part specifications were confirmed, allowing the team to order several parts. Below is a table of several parts acquired, however, many others have also been ordered. Over 80% of all parts have been ordered or acquired, as seen in our Updated Bill of Materials
The main testing that was conducted this phase was to create a simple, working version of LabView, and to create a detailed test plan for the diaphragm / chamber, and the flow meter for measuring stroke volume. Since critical parts will be arriving next phase, the majority of testing will be completed then.
Ideas for stroke volume measurement were also explored, such as the use of an IR Sensor.
