Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Began analysis of slider crank method and brainstorming ideas for actuation.
Solidworks analysis of variable rotations for slider crank method.
Accomplishments from Previous Week
Model built for slider crank design.
CAD files ready for 3D print, however 3D printer was out Friday, so printed had to be postponed until Monday.
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Linear actuator research and spec/pricing. Brian
Sensor analysis, placement, ongoing. Chris
Slider Crank CAD model transitioning to actual materials (Alum Tubing, etc) Meagan.
3D print of covering model (delayed due to printer downtime). Chase
Casing and unit display research/CAD. Randy
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments
Sponsor was satisfied with overall progress, and urged us to continue generating ideas.
Space footprint for unit is not a concern, we can decide to go with a vertical or horizontal unit at our discretion.
Sponsor recommended treating leg as a truss element for sensor analysis.
Access to 3D printing at DJO if required.
Instructor Comments from Last Meeting and Actions Taken to Address these Comments
Views of linkage mechanisms generated in side view to display range of motion.
Slider Crank linear bearings, linear slider problem. Investigating use of a linear actuator to alleviate issue.
Investigated worm gear drive mechanisms.
Risks and Areas of Concern
Linear Actuator pricing/lifespan
Bearings for linear slider portion of slider crank.
Sensors sensors sensors.
COTS parts vs machining custom parts
Enclosure
Resources or Information Required but not Available
Anthropometric Data from DJO.
CAD models of specific knee braces and leg from DJO.
Schedule
Describe upcoming milestone
Update Gantt chart.
Budget (list amount spent and amount remaining)
$9.14 spent
~$2490 remaining.
Progress on Report and Webpage
Webpage is up to date with design history and multimedia uploaded including videos. Sponsor has access to webpage and is now tracking group progress through announcements and updates.
