Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Iterations on the gripper and translation system are being continued
More prints of the gripper are being put together and tested
This includes the use of different motors and operating mechanisms
Proof of concept for the gripper has been achieved
We are still continuing to optimize the gripper
The translation system has been updated per review of instructional staff
Accomplishments from Previous Week
Made improvements to the translation system model
Established proof of concept of the gripper
Performed simulations on cantilever
Made progress on code used to operate the system
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Receive parts for the translational system and begin constructing apparatus (All)
Continue to iterate the gripper design and possibly modify for machinability (Angela, supported by all)
Continue work on the code for the system (Manuel, supported by all)
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Sponsors expressed preference for a gripper mechanism that has two free-to-translate parallel grippers
Gives more room for error in alignment of slides
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Instructors gave input on both the gripper and translation system mock-ups.
The large amount of friction created during the gripper's motion was addressed. The professor suggested a design that rotates the moving gripper
into place (rather than translating)
Concerns with precision and vibrations in the translational system were discussed. We scheduled a second meeting with Steve and he gave input
on how to mitigate problems in these two areas. For example, he suggested the use of an A-frame to help the system achieve linear motion.
Comments from Other Students in the Class (indicate date of comments and if via email or in person)
There were no comments from other students in class during this week
Risks and Areas of Concern
We are still using 3D printed models for the sake of testing. This is not completely accurate as the sponsors would prefer that parts be machined to
increase their reliability and robustness.
Resources or Information Required but not Available
We do not have access to machining
We have experienced longer shipping times from manufacturers
Schedule
Construct the translation system
The GANTT is updated under its tab
Budget (list amount spent and amount remaining)
Fasteners and bearings for the gripper were purchased. Motors for the translation system were also purchased.
We were allotted $1250 in fund and have spent $192.53
We have $1057.47 remaining in our budget
Progress on Report and Webpage
The report and webpage are being updated as the design process continues. The first full draft of the report is being written and the webpage is being updated regularly.
