Accomplishments:
- Updated codebase to detect facial curvature and three-dimensionality; work-in-progress
- Emily’s camera sort of works now; using 3D data from the camera to update my code as well
Upcoming Work
Still trying to integrate my code with Emily’s facial data, and hopefully that will be done next week, since she has a better understanding of how to use the camera.
Schedule
I had a midterm this week, and an essay due by the end of the week, so I’ve been working on that a lot, which meant I was unable to work on capstone too much. The whole team will be meeting up next week to combine some of our work together.

This week has been busy, with midterms and big homework assignments. However, I was able to get the proper python libraries to build on my computer and put point cloud data to .ply file for now. I have been working on building the python bindings on the raspberry pi. It seems that the raspberry pi does not have enough memory to support the compiling with the desktop at the same time. Even then, it often runs out of memory. I configured a 1Gb swap file to finally make it compile. This was already after I had tried to cross-compile using an ubuntu vm, which ended up being a cmake file disaster. For the servos, I was able to move around some weak servos at home using the metro. The bigger servos just came and I will be testing those, and starting to design the housing.
I am slightly behind due to work from other classes, and I hope to make up ground by finishing up integration with Jason. We have several meetings planned to get the 3D face detection up and running so we can do testing. As for the servos, after I make sure that the higher torque servos will work, I can start planning out the enclosure so that they actuate the deadbolt, and then most of our project will be done.

This week I ordered a bunch of more parts. I should have all the components I need to finish the inductive power. It’s hard to judge how efficient the power transfer is, given that the function generator seems to supply different max currents for different frequencies. While I have been waiting for components to arrive, I have been trying to characterize the max power transfer, and depending on the efficiency of the DC adapter I bought from amazon, I should be able to achieve about 2x the power requirement I had set during the design phase. Another aspect I have been working on is to design the circuit for the 2.1 mhm 555 timer to output at 100khz pwm. I believe that my math is correct, and once the timer arrives I can build the circuit and verify via oscilliscope.
The goal for next week is to spend most of my time building circuits, and have significant testing and data on those power systems.
Whole Team:
Despite having a lot of other work this week, we think that we made a decent amount of progress. 2/3 subsystems are nearing completion, arguably the most important 2 subsystems (embedded stuff and software), so we think that we are on good pace to close out the project.
