156B Week 10

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

• • Resistance force feedback tested

  • tracking / recording algorithm tested

  • Sound feedback algorithm developed and implemented

  • More iterations of extensions piece with different offsets of the slots printed

  • Construction of base initiated

  • Range of motion measured

Accomplishments from Previous Week

• • Universal joint remodeled and reassembled to account for the press-fitted bearings issue

  • Extension piece with slots with different offsets tested

  • Combined arms, trajectory, and resistance code confirmed (without connecting to the arms) that they run

  • Found the encoder on one of the motors was broken. Switched with the one on a motor that we’re not using and confirmed it works

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

• • Alex & Eric:

    • Polish code

  • Jackie & Daniel:

    • Determine the orientation of the arms that is the most suitable

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

• • Given information of the manekins and discussed ideas for the base to mount the arms (in-person 6/1)

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

• • Tackle mechanical component first to determine the cause of misbehavior (in-person 6/1)

  • Tackle the data gathering process (in-person 6/1)

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

• • N/A

Risks and Areas of Concern

• • Range of motion with the actual manekin

    • Seemed sufficient before but some issues arose when tested with the manekin

  • Durability of the cables

Resources or Information Required but not Available

• • N/A

Schedule

• • Milestones (FINALS WEEK)

    • Prepare for the poster
