156B Week 6

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

• • Gripper is being iterated and tested

  • Working on software aspect of automation

  • Waiting on parts for translation system

Accomplishments from Previous Week

• • Prototype of the tension gripper was made and another iteration was tested with new springs

  • Continued writing Arduino libraries for automation processes

  • Parts for translation system were purchased

    • OX plates are to be 3D printed for now by sponsor

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

• • Finalize gripper design (Angela)

  • Have "rough drafts" of most Arduino libraries completed (Manuel)

  • Start construction on the translation system as parts arrive (All)

    • Troubleshoot any problems with implementation (Alanna, Kieu)

  • Integrate wiring into translation system (Alanna, Kieu)

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

• • The sponsors approved of purchases for the translation system

    • Sponsors were concerned about high cost of OX plates

    • Sponsors want to 3D print modified (toleranced) OX plates for the prototype

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

• • There were no comments from instructors during the proof of concept presentation

    • Darren remarked that we should upload all updated files to the website

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

• • There were no comments from other students in the class during the proof of concept presentation

Risks and Areas of Concern

• • Gripper motor overheating over long period of usage

  • Alignment of translation system (expected, not seen yet)

Resources or Information Required but not Available

• • OX plates are very expensive

    • Could machine our own, but no access to machine shop

    • Still expensive on eBay and other sites

Schedule

• • Mechanically build the translation system prototype

  • See Gantt chart tab for updates

Budget (list amount spent and amount remaining)

Progress on Report and Webpage

• • Report and webpage are being updated as more progress is made.
