FORAY - Testing adafruit feather board software and hardware

Zhaoliang Zheng

I've been testing the adafruit feather board software and hardware recently and I found some very interesting problems: Upload program In the windows, when upload program to the feather board, it doesn't have to press the reset button. But in the Linux, it has to press the button in order...

BTO-RRT algorithm has been released

Zhaoliang Zheng

According to the reply from the editor of Journal of Intelligent & Robotic Systems(JINT). The system returned it back to author because it was incorrectly submitted. I'm still communicating with the editor to find out why. The previous reason I thought was I need to link the repository, which it h...

FORAY - Near-perfect calculation of ball location and scope for better estimation

Aaron John Sabu

Over the last two weeks, I have been working on the existing code by Parth Agrawal for the estimation of the location of the green ball from images that were shot at different angles. The code had estimated the position of the ball quite well for the hi-def images but not so for the 800x600 images:...

Blimp autonomy block diagram

Shahrul Kamil bin Hassan (Kamil)

The general idea of the blimp autonomy is that the controller that we are using for the blimp will receive multiple inputs which will determine how the blimp is going to move. On a high level, the camera detect the objects like the green balloon, opponent's blimp, and the goal post. That, along with...

Mesh Network: What is the best way to create a mesh network for our blimps?

Bhavik Joshi

Over the past week, I have been looking into what are the best tools/ways to create a mesh network for our ESP32 boards that will be attached to the blimps. The three frequencies we want to add to diversify are 2.4 GHz, 433 MHz radio, and mmWave 20 GHz. For the 2.4 GHz option, ESP-now looked like...

Dashboard requirements

Grace Kwak

Dash I worked with the team of undergrads to develop this initial list of requirements for the dashboard. It's based on the kinds of experiments we plan to run and what kinds of data will be relevant. Of course, this is a preliminary list only, but I've specified that we will use modular design so...

FORAY - Testing the streaming function of opti-track system

Zhaoliang Zheng

Current progress: In the past week, I tested the opti-track system streaming function. Before, after I used opti-track to capture the motion of our flying blimps, I had to manually import the data to a csv file and then process the csv file. This whole process took a very long time since in the...
