156B Week 2

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

• • CAD of structure is completed

  • Motor and electronics CADs are being completed/researched

  • Probes have been 3D printed for future testing

Accomplishments from Previous Week

• • Completed CAD with updated design for SonoHand

  • 3D printed sample probes

Goals for Next Week (list names after each item). Use specific and measurable objectives.

• • Complete CAD of electronics and motors that are to be added as actuators

  • Start to purchase parts (mainly McMasterr)

  • Test hand to see if it can clip onto the probe well

Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)

• April 3, 2020; Zoom

  • • The locking mechanism should be actuated via motors+button (plugged into an outlet) or a foot pedal. Knobs will not work because it takes too much time during a procedure to adjust

      • Changed our CAD design to respect this decision

    • The arm fixture needs to be around an arc with a 2-3 foot radius

    • Probes that we will work with are Sonosite's HFL38XI and C60.

      • We will receive dimensions of the probes from Preetham and CAD one out and find STL files online of other probes to 3D print one for prototyping

Instructor Comments from Last Meeting and Actions Taken to Address these Comments  (indicate date of comments and if via email or in person)

• • April 2, 2020; Zoom

    • Conduct more simulations

    • Create more CAD

    • Start on the report ASAP

    • Utilize Onshape or Fusion 360 if SolidWorks issues arise

    • A physical prototype is desired still, but we should take it as far as we can

      • We will conduct simulations to ensure a working product before sending it to shops. In addition, Simon has access to a lot of equipment at his dad's company to help create the products and budgeting issues
