156A Finals Week
Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Additional risk reduction we considered was the internal battery power requirements needed to power the previous team's system. This information was used for Chikeng's component analysis.
Accomplishments from Previous Week
Completed risk reduction presentation
Completed 4 individual component analysis
Goals for Next Week (list names after each item). Use specific and measurable objectives.
No set goals over the spring break besides optional work on creating new system designs
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
The sponsor told us to come up with multiple designs for the nerve lengthening system and to be prepared to present them to him next quarter. Currently we have two system designs, not including the previous team's design. The two designs are:
lead screw - stepper motor design
electromagnetic - dc motor design
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Look at previous team's work to build off of (3/28/19 during Risk Reduction presentation)
Comments from Other Students in the Class (indicate date of comments and if via email or in person)
The lead screw system we showed in the presentation would need a rail to ensure that the nerve gripper does not spin (3/28/19 during Risk Reduction presentation).
Risks and Areas of Concern
Satisfactory stepper motors are very expensive while cheaper stepper motors might not fit the size constraints
Encasing of lead screw system to allow bio-compatibility
Research bio-compatible materials
Resources or Information Required but not Available
None
Schedule
Describe upcoming milestone
Come up with new system designs
Update Gantt chart.
Budget (list amount spent and amount remaining)
$0.00 spent
$1500.00 remaining
Progress on Report and Webpage
Preliminary risk reduction and 4 component analysis are complete
Received previous work from prior team's nerve lengthening system
Internal pages up until the current week are complete
