*156B Week 8

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

• • Established electronics communication to hardware

  • Built linux workspace

  • Tested position code and working on testing code with combined arms

  • Discovered possible broken encoder

  • ReCAD, recut, and reassembled U-Joints

  • Testing extension handle prototypes

Accomplishments from Previous Week

• • Wiring of electronics boxes and WoodenHaptics arms complete

  • Micro-controllers flashed with necessary software

  • Installed Ubuntu 16.04 to run Chai3d software

  • Existing code double-checked for errors

  • Redesigned the extension handle piece to allow more translational movement

  • Recut some pieces and re-cabled so the wires have more tension

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

• • Alex & Eric: implement combined arm code, expert trajectory, and resistance.

  • Jackie & Daniel: test the arms and compute some “numbers”

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

• • Integrate light source into laryngoscope handle (in person 5/12)

  • Treat roll motor as a stretch goal (in person 5/12)

  • Re-do some aspects of cabling (in person 5/12)

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

• • Split time spent on report writing more evenly (in person 5/11)

  • Jumper wires available on campus (in person 5/11)

  • Work on finishing U-joint as soon as possible (in person 5/11)

Comments from Other Students in the Class (indicate date of comments and if via email or in person)

• • Dress more professionally for presentations (via email 5/11)

  • More information on software in presentations (via email 5/11)

  • More annotations/diagrams and less words in presentations (via email 5/11)

Risks and Areas of Concern

• • Undetectable roll caused by larger slots on attachment piece (meant to allow for more translational motion)

  • Durability of 3D printed components, especially new attachment piece

  • Hidden software errors/problems not discovered through inspection

Resources or Information Required but not Available

• • N/A

Schedule

• • Milestones (week 9)

    • Test the software to track the movement of laryngoscope

Budget (list amount spent and amount remaining)

• • Total Spent: $4213.77

  • Total Remaining: $86.23

Progress on Report and Webpage

• • Revisions for the second draft have been made but will be continued

  • Some images/CAD files have been added to the website
