156B Week 7
Overview of Status of Analysis, Design, Fabrication, Tests, etc.
All the components are ready for integration. Enclosures for the base station consisting of the raspberry pi and calibration rig need to be 3D printed.
CADs of wrist and hand enclosures are being finalized
Data from 1 pressure sensor can be graphed via the raspberri pi
PCB boards came in the mail yesterday
IMU code still needs some more time to get to work
Calibration rig board broke, new ones on the way.
Accomplishments from Previous Week
One Tactilus sensor is linked to the ESP32 and then send data to the raspberri pi which can be graphed after recording the data. In other words, we can graph it but not live stream
Resistor value has been chosen for the needed resolution using the 1M ohm potentiometer
New CADs of enclosure for the components on the wrists has been created
Goals for Next Week (list names after each item). Use specific and measurable objectives.
3D print enclosures and any CAD (Euan)
Integration (everyone)
Attempt live feed of sensor (Kyle, Michael)
Send data from more than one finger pressure sensor
Finish cads for enclosures (John)
Sponsor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
Keep in mind the file size limitations in the file formats that data will be saved in (try to make sure you can fit at least 5 operations at ~2 hours each)
Think about including both a USB stick and a microUSB cable in the project
Try to find an easy way to reset the Raspberry Pi safely
Coworker(s) will be coming to the sponsor meeting week 8 and if the test goes well, we can test in the endoscopy unit week 9
Dr. Chang is attending a GI meeting in Washington during week 10 so we will be scheduling the poster session soon
Instructor Comments from Last Meeting and Actions Taken to Address these Comments (indicate date of comments and if via email or in person)
The chosen wire connector might be too large (might be meant for lower gauge wires) and it might cause issues (especially considering its size at approximately 1.2x1.2 inches)
Think about how you're going to calibrate the IMUs (like absolute calibration versus relative calibration)
Comments from Other Students in the Class (indicate date of comments and if via email or in person)
N/A
Risks and Areas of Concern
Report needs to be worked on.
Resources or Information Required but not Available
N/A
Schedule
There is another presentation next week and we will try to have all the sensors ready for that event
Budget (list amount spent and amount remaining)
Most of the parts have been purchased from last week. There may be some smaller parts needed costing <$100 total
Progress on Report and Webpage
Report is being revised by team 20 Cough Simulator
Webpage will be update soon!
