Week 4 Instructor Meeting

Post date: Feb 01, 2012 11:8:53 PM

Overview of Status of Analysis, Design, Fabrication, Tests, etc.

• • Our sponsor Dr. Strain volunteered to lend the entire XY stage and microscope to our workspace in EBU 2 for the remainder of the project.

    • So far we have taken ONLY the XY Stage

    • Primary goal is to tie this XY system into provided vertical motor stage, controller, and power supply.

  • Continuing research on methods to lift and place: Fernando and Clark will report on meeting with Professor Talke

  • Found a suitable camera; order has been placed in system.  No image processing will be necessary.

  • In process of getting a Micro-Injector to test.

Accomplishments from Previous Week

• • Initial Design Proposal and outlined tasks to Week 6.

  • Sponsor meeting: status update & equipment gathered

Objectives for the Upcoming Week

• • Full computer control of X-Y axis (using provided VI program) (greg, jonathan)

    • purchase serial cable adapter (greg)

    • verify USB COM drivers

    • gain an idea of precision

      • perform a test to measure length per step

      • is there accuracy over large distances? (perform a test to see if 400 counts equals same distance in one corner of the slide as the other)

    • CAD of assembly (laith)

  • (by sponsor's suggestion), meet with Professor Talke (Fernando, Clark)

    • present problem definition and our idea for magnetic materials

    • ask for feedback

  • 'SIXPACK' controller Manual and Wiring (Everyone)

    • map wire diagram from output on controller board to stepper motor (z-axis)

  • LabView VIs (Greg)

    • gain insight into VI controller program

    • devise possible ways to incorporate third motor into same program

  • Be ready to test the Micro-injector when it arrives:

    • Mount for the Z axis or arm for tool ( Clark, Fernando )  

Sponsor Comments from Last Meeting and Actions Taken to Address these Comments

• • We discussed taking the microscope from his lab.

    • Took everything but the microscope and the pneumatic table that it rests on.

  • Camera

    • Told him we were ordering a Cmount camera he approved

Instructor Comments from Last Meeting and Actions Taken to Address these Comments

• • Powerpoint updated to reflect instructor's comments (posted to site)

Student Comments from Last Meeting and Actions Taken to Address these Comments

• • Highlights of Feedback from Design Proposal Presentation

    • Nanoindentors to be used for z-axis precision

      • Piezos could be used as sensors for depth but we are not trying to make contact with anything so this will most likely be used.

    • "Will the cells burst when sucked into micro-injector?"

      • Sponsor is doubtful this would occur

    • Majority consensus saw most promise in the vacuum (via microinjector) method

Risks and Areas of Concern

• • In meeting with Prof. Talke we will discuss our concerns regarding magnetic methods.

Schedule

• • Turn on the XY stage (1/31)

  • Understand how to use the LabView VI. (by 1/3)

  • Plug Z axis into the power/control box.

    • Figure out how we have to wire in the third axis to the SIXPACK (1/5)

Budget (list amount spent and amount remaining)

• • Camera

  • USB - Serial converter

  • Microinjector
