Boat actuation mount design

Grace Kwak

I have begun testing different designs for mounting servos and DC motors in any orientation and at any position on each of the boat hull morphologies, as shown in these photos: servoMountDesigns.pdf. I'm testing them by hand first (using tape and scissors), before sending them off to Jill for her...

Three Node Mesh Network Demonstration Using painlessMesh

Bhavik Joshi

This week, I used the painlessMesh library to create a very simple mesh network of three nodes. I wrote the code to resemble how I believe our blimps/ RoCo robots should use the network once they are automated: they send instructions to one another that is interpreted in a switch statement, these in...

Camera Setup for Visual Processing

Marisa Duran

This past week, I have been working on setting up the camera hardware for the visual processing that I will be working on. I started by setting up the ESP32 Cam, which uses the Arduino IDE. There is an example for ESP camera boards that can be used to set up a video stream on a web server, which is...

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...

ESP Wifi Module and Blynk Software

Ryan Chen

Recently, I have been working on connecting the ESP Wifi Module and the Blynk software. I have been looking into both emulation and ESP Now. Additionally, the Blynk software for controlling the motors does have capabilities with Bluetooth, so I will also be testing the Blynk software with my HC-05 m...

FORAY Integration Test - Motor Driver + WIFI

Parth Agrawal

Microcontroller - ESP32 Motor Driver - TB6612FNG Dual Motor Driver Propeller Size - 45mm (diameter) Communication - WIFI Module using Blynk I also found out that ESP32 does not have a native implementation of the AnalogWrite function. This has led to problems for PWM. I will look for a...
