Overview of Status of Analysis, Design, Fabrication, Tests, etc.
Received the last parts needed for cabling and U-joint
Cabling of the arms has been completed
Electronics Boxes from Jonas received and are being assembled
U-joint will be assembled and tested along with roll joint later this week
Accomplishments from Previous Week
Micro-controller code received and minor code changes implemented
U-joint CAD complete
Roll Joint Prototype made and will be tested with U-Joint
Physics software is functional and ready for live testing once robot is fully built
Goals for Next Week (list names after each item). Use specific and measurable objectives.
Alex and Eric: Put together Electronics Boxes, implement point-tracking code, test physics code when system is ready
Jackie & Daniel: Test U-joint and roll joint. Adjust design (dimensions, weight etc.) accordingly
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
To test the program, test each arm individually with gravity compensation first in order to confirm that it works at least for one arm (via email 5/7)
To have a “kill switch” in case the system starts acting wildly (via email 5/9)
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
N/A
Comments from Other Students in the Class (indicate date of comments and if via email or in person)
A student commented on the weight difference between the 3D-printed laryngoscope handle and a real handle. With the motor, the replica feels close to the actual weight but will adjust accordingly although the important thing is that the shape of the handle is easy to grip (5/4 in class)
Abstract needs more clarification on the specific terms (WoodenHaptics, Chai3D) as well as “numbers” (test results, force etc.) (5/9 in class)
Risks and Areas of Concern
Inevitable software issues
Simultaneous connection to multiple micro-controllers
Large amounts of code developed without intermediate physical verification
Durability of 3D-printed laryngoscope handle
Durability of motor shaft, will adjust design to mitigate this risk
Durability of U-joints
Resources or Information Required but not Available
How many grams is $100 of 3D printed materials? (Note to selves: Ask Chris Cassidy)
Durability of 3D printed materials (still need testing)
Laser cam speed/power setting that best cuts our parts without burning the wood too much and how to change the settings
Schedule
Milestones (Week 7)
Finish “Sanity Check” software testing of kinematics and experimentation of haptic feedback and force tool to stay in 1 spot
Test the arms with joints
Dimensions need to be fixed?
Can withstand input force?
Budget (list amount spent and amount remaining)
Total Spent: $4139.92
Total Remaining: $160.08
Progress on Report and Webpage
Delegated weeks 6 report/webpage responsibilities, Submitted the first draft of the final report
