156A Finals Week
Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Acrylic anchor for string broke on one segment. Was fixed by drilling and installing a metal pin to anchor string.
String snapped on second segment. Different string materials and strengths should be tested to increase maximum tension.
Five sleeve iterations created to increase stiffness and reduce failure of segment. Must continue to work on sleeve fabrication process.
Accomplishments from Previous Week
Individual Component Analysis research: IMUs (Torin)
Individual Component Analysis research: Twisted string actuation (Carver)
Individual Component Analysis research: Motor ( Yuan)
Individual Component Analysis research: Spring (Byron)
Risk Reduction (all members)
Manufactured 5 versions of a sleeve to increase stiffness of robot
Designed experiment to test stiffness of each sleeve
Tested performance of robot with sleeve
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Correct CAD design to leave increase space for wiring and PCBs and increase strength of acrylic string anchors
Fabricate new segment
Connect and test two segments
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Contacted sponsor to order IMUs for next quarter.
Risks and Areas of Concern
Strings break under excessive tension, as do acrylic anchors for string.
Progress on Report and Webpage
Individual Component Analysis reports completed
Risk Reduction experiment and presentation completed.
