FORAY - Test live video with ML color detection and color threshold methods

Zhaoliang Zheng

Color threshold + web cam: Video size: 800 * 500 ML model + web cam: Video size: 400 * 250 The reason why this is slow most of the reasons are because this section takes too long to run: # take too long this step for i in range(h): for j in range(w):...

foray- ESP32 Cam range check with and without antenna

Warnakulasuriya Shelard R. Fernando

ESP32 Cam Range check This week we tested the Wi-Fi connectivity range of ESP32 cam with and without antenna. ESP32 Cam with Antenna: We were able to achieve a range of 130ft. When it reached 130ft it had slow response time. ESP32 cam without Antenna: We were only able to achieve a range...

Mean-field Improvement1: add the observation range

Zida Wu

This improvement is based on the previous posts, corresponding to the first step: Step 1: Deal with information problem: using only closest neighborhood information. Code is here The main improvent is to set the observation field. Current mean-field assumes all agents' information are av...

Board Design Tools for the 21st Century and Introductions

Richard Lin (Ducky)

Hi everyone! I'm a new postdoc with LEMUR, and I'll be working on modern tools for circuit board level electronics design. So that's a lot of words, let's unpack that. Modern board design tools (like KiCad) consist of schematic capture (drawing the schematic) followed by layout (placing components...

FORAY - Setup the prototype

Zhaoliang Zheng

This week, we started to get all the new members know how to build a blimp from sketch. Next week, we will be working on the altitude control using ultrasonic sensor. Meanwhile, some ideas that we are thinking about: (1) Modify the propulsion system, use only 1 motors at the side of blimp...

How to use git for collaborative code development

Zhaoliang Zheng

Problems that I've been thinking about: How can collaborative code development be more efficient? How do avoid conflict when multiple people are developing? How make the code more readable, easy to maintain and debug? A successful Git branching model: (Simplified version) A example...

What is a Quantum Kalman Filter?

Cody Fan

A quantum Kalman filter is a recursive Bayesian filter used to predict and estimate the state of a quantum system, and was first introduced by Viacheslav Belavkin. It is described in his work (Belavkin, 1999). Another interesting work is the quantum extended Kalman filter. However, much of the r...
