 WEEK 2

I currently have a small project that I'm very passionate about and have been working on: an embodied intelligence/edge AI project.

It's similar to a companion-type desktop robot. My main goal with this project is to build and manage a complete system encompassing perception, cognition, decision-making, and execution.

Below are the hardware circuits I've already built, along with some of my structural plans.


This is the current hardware circuit design, and it's unlikely to undergo significant modifications in the future. The speaker, servo motors (which are inductive loads), and multiple power-consuming sensors may generate various frequencies of noise, as well as voltage drops or instability issues when operating simultaneously (especially the servo motors; I didn't use a driver board due to size constraints). Therefore, the circuit primarily utilizes filtering circuits composed of small-capacity ceramic and electrolytic capacitors (multi-stage decoupling), as well as large-capacity electrolytic capacitors to stabilize the voltage.

In terms of signal processing, due to the specific characteristics of the I2S digital microphone and the power amplifier module driving the speaker, I mainly employed damping resistors and AC coupling circuits.

In addition, there are self-resetting fuses to protect the servo motors, as well as small surface-mount components for electrostatic discharge and surge protection.

This link contains my structural framework and the perception module, which I have mostly completed.


For the project ideas for this course, I mainly have two ideas, both revolving around the main project I'm currently working on.

First, my first idea is to build a solar power station for my small robot to provide auxiliary power to the system. I hope this can save some power consumption and allow for quantifiable monitoring of how much electricity is generated and saved each day. I think this is quite interesting and meaningful.

My second idea is that the initial design of this small robot was to serve as a companion/assistant.  Therefore, it should be able to obtain some of my biological information, such as heart rate, blood oxygen levels, and other basic biochemical information. So I'm wondering if I can create a small device that generates electricity using my body heat, collects my biochemical information, and then sends it to the robot. This information would then be used as part of its PERCEPTION STATE to help it build its COGNITIVE abilities and react according to my different states.

I have already purchased an LTC3108 power manager to receive and manage the generated ultra-low voltage electricity. I have also purchased dozens of solar panels that can be freely soldered with positive and negative terminals and connected in series or parallel. I also have bismuth telluride semiconductor thermoelectric generators. For energy storage, I have lithium batteries and am considering purchasing supercapacitors.

 WEEK1 I watched the video and read the article, and also briefly skimmed through the optional articles. I found the concept of "deep listening" mentioned in the TED talk to be the most insightful. The explanation in the talk was somewhat vague and general, so I did further research on this concept myself. Here are my thoughts: First, listening is a subjective experience, influenced by each person's background, and differs from purely physical "hearing." If I were to define "deep listening," I would say it is an acquired ability to perceive and understand; but I prefer its philosophical meaning: it is a way of observing the world and experiencing one's own existence by transcending personal biases and integrating one's limited life experiences into a broader historical and environmental context. Deep listening should encompass both time and space dimensions: Time encompasses both the past and the future. For example, the sound of a piano isn...

 WEEK1 I first brought my photo into Photoshop so I could use the Mesh tool to get the coordinates of any point. My main challenge was choosing which function to use to draw my image. I initially used Bezier curves, but I found their two control points too abstract and difficult to manipulate. I then tried curves, but again, I struggled to accurately control the curve's shape using the control points. Finally, I settled on the beginShape and endShape functions, which allow me to draw irregular shapes using precise point coordinates, which perfectly met my needs.

What I wanted to achieve was that as I moved the mouse, the pattern would disappear within the circular area around the cursor. First, I used a grid and a for loop to draw the pattern across the entire screen. Then, to determine whether a portion of the pattern wa...

 Week 1 I have read the rant about basic electricity, DC power supplies, introduction of different components and the two readings rants.  I also the attachment rant about smell in the e-mail that was sent by teacher. I learn a basic concept about these basic knowledge, and I also learn a lot of new English vocabularies and so no. The point of view in the  Bret Victor,  A Brief Rant on the Future of Interaction Design  inspires me a lot, human capability is the thing that I really ignored before. WEEK 2 In the third picture is my understanding adout the components structure of processor after I had read the rant. I hope teacher can take a look and give me some error correction. This is the vedio of practicing digital output and input. This is practicing the analog input. I didnt use the  potentiometer, but I use a pressure sensor to control the brighten level of the LED. So I have to change the circuit. I put a 10k resistense in series with the sensor in or...
