Overview of Status of Analysis, Design, Fabrication, Tests, etc.
The CAD designs are being refined as input is given and 3D printed models of these designs are being fabricated and tested.
Calculations for the translation system are being carried out to make decisions on purchases.
Accomplishments from Previous Week
We 3D printed prototypes for the grippers to accommodate for the use of tension springs.
Testing showed that the current design was unfeasible because the parts are too small and fragile.
We also simplified the arm design for the translational robot such that a cantilevered portion supports the gripper
and allows it to access the spin coater.
We also narrowed down the list of required electrical components for the overall system and received some
components from our sponsors.
The translational system has been updated and calculations for selections of components were performed.
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Design an adapter to connect gripper to the cantilever beam (attached to the z-axis) - Angela
Begin coding some simulations to start code framework for automation system. Specifically, start simulation of translational
system that incorporates I2C communication between multiple boards - Manuel
Perform calculations on system performance (e.g. vibrational analysis, fatigue, etc) - All
Iterate the translation system as needed per sponsor and instructor input - Kieu, Alanna
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Sponsors delivered electrical equipment (breadboards, Arduino, power supply, electrical tape) to a team member (in person)
Sponsors would like to see work on automating the storage area of the system (Zoom)
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Instructor gave feedback on the use of tension springs in the gripper design such that the movement is not overconstrained.
Instructor suggested working on the pseudocode for the automation of the system.
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 the class during this week.
Risks and Areas of Concern
We still expect problems with the gripper because of the use of PLA filament. Printed samples have broken after extended use.
Position control is another area of concern considering that the system requires high precision
