Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Completed the primary goals of the project
Can control a single spherical object through proportional controller and maintain it within the field of view
Finished all hardware machining except honeycomb diffuser
Working on controlling plankton in the center of FOV and increasing the robustness of controller
Accomplishments from Previous Week
Troubleshooted all of the serial communication components and found that our pump (UART chip inside the pump) was at fault (Teng)
Purchased a new pump (Yuling)
Purchased a new set of RS485 cable and RS485 to RS232 converter. (Yuling)
Purchased shut off valves (Yuling Shen)
Successfully set up communication between PC and the new pump (Kimi and Teng)
Achieved proportional control and managed to keep the object at the center of the field of view (Kimi and Teng)
Designed a simple graphical user interface for the pump control code (Teng)
Complete serial communication between C++ result and MATLAB controller (Kimi and Teng)
Troubleshoot air bubbles (Damien)
Compiled results from prototype testing
Wrote 2nd draft of report / peer graded
Machined honeycomb diffuser in machine shop (Yuling)
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Fix the honeycomb deformation issue and test the machined honeycomb (Yuling and Damien)
Test the control algorithm on dead plankton (all)
Wait for etched or laser cut honeycomb quote and might consider for purchasing (Kimi)
Install shutoff valve (Damien)
Determine error in velocity measurement (Damien)
Draft of Poster / final revisions to Report (all)
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
No meeting with sponsor last week due to schedule conflict
Will meet with sponsor this Thursday for current design review and work on plankton.
Have updated sponsor on progress via email; they are very pleased
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
No meeting with instructor due to in class design review
Comments from Other Students in the Class (indicate date of comments and if via email or in person)
Student recommend use another material to resolve warping issue and we are working on that
Student recommend use integral controller to eliminate steady state error and we are working on that as well
Suggested bleeder valve for air bubbles
may not be feasible due to size of chamber and fasteners
Risks and Areas of Concern
