Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Finished creating scaled prototype for the ratchet design and tested functionality with rubber bands as makeshift nerves (Kevin)
Finished creating to-scale motor enclosure assembly (Andrew)
Accomplishments from Previous Week
Assembled prototype motor assembly and enclosure (Andrew)
Tested one-way bearings for backlash. (Andrew)
Tested scaled ratchet-mechanism prototype with rubber bands, (Kevin)
Created CAD numbering/naming system. (Andrew)
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Finish interfacing of the motors with the Arduino. (William,Wesley)
Order more bearings for the spool design. (Andrew)
Refine enclosure/mechanical stop design for better DFM WRT endmill max lengths of cut. (Andrew)
CAM motor-spool assembly parts. (Kevin)
Machine said parts (Andrew, Kevin, Wesley, William if time is available)
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Dead Rabbit should be available for testing this week. (1/30, in person)
Working on Arduino implementation of motor in order to proceed with testing.
External actuator is viable if detachable between each nerve lengthening step. (1/30, in person).
We view this as a worst case scenario
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Found o-rings that can be used in motor design, but it might not be needed, seems that it sealed enough. (1/29, in person)
Comments from Other Students in the Class (indicate date of comments and if via email or in person)
Risks and Areas of Concern
The ratchet prototype is working but its not very smooth, need to test further.
Resources or Information Required but not Available
Schedule
Will be able to test designs in a dead rabbit soon. Hopefully within a week or two
Budget (list amount spent and amount remaining)
$79.07 Spent
