Carnegie Mellon ECE Capstone, Spring 2020: Ashika K, Abha A, Jade T
This week, all three of us worked on integration and improving our system to prepare for the demo next week. Ashika and Abha worked on improving the display, and Jade worked on improving the pi to laptop socket communication. Abha also continued to work on …
This week I worked on improving the pi’s main function as well as cleaning up the socket code. Specifically I worked on making it so that the program would close the sockets when done running and also not hang if something happened to a socket …
On Sunday, I cut out the cardboard pieces for the head, and one of the arms.I also found a mini servo motor in my home, so I attached that to the arm. I soldered the motor shield that came in last week, and attached it …
This week, Jade created a server/client program for laptop to raspberry pi communication, primarily for the audio input/output. Abha worked on installing all the necessary packages and tools, both on her laptop and the raspberry pi, to run the storytelling algorithm and the audio components. …
This week, for the storytelling component alone, I finally finished grammar correction for nouns and I worked on creating a few more templates. I changed the format slightly to improve sentence tokenization, which makes it easier to send the story sentence by sentence to the …
On Monday I worked on cleaning up the socket interface code. I wrote read and write functions for both the server and the client. On Wednesday I worked on integrating socket code into our program, this consisted of creating a new main file for the …
On Sunday, I tried to debug the issues with showing an image on the eyes display through an SD card. Initially, my plan was to put an image of a cat eye on the SD card, and the eye display would read it. Most of …
This week I started integration with Abha for the text display. On my end, I created a display window (shown above) in Python that runs on a separate thread from the main program. This window is the same size as the pi and displays the …
What we did: Abha worked on the face display on the hardware side, updated the CAD files to reflect the design changes for the head, and wrote code to move motors via a Raspi. Ashika wrote code to display the sentence output on a graphic …
On Sunday I decided to tackle the choppy audio quality that I was getting from the audio playback. I was using pydub’s AudioSegment to play the sound back, but it was choppy, so, I investigated a few other audio processing packages including pyglet, pygame, tkSpeak, …
