How to Build a Startup for Remote 4G Drone Operations
udemy. com/course/lets-build-startup-for-remote-4g-drone-operations
In this Project/Course we are building a Cloud Application for Remote Drone Operations
from the grounds up - line by line - from 0 to the complete working solution.
Application main capabilities:
- on the web page user will be receiving very low latency live video stream from all of
the drones
- sharing video link with anyone anywhere in the world,
- seeing all of the drones on the interactive map,
- full manual control of each of your custom build DIY Drone
- control it from anywhere in the world,
- at any time to setup and activate missions on any of those drones while they are
flying.
Tech used:
- Java, to build a single file easy to deploy backend of our cloud platform that will
manage drone connections. This is a control station app in the form of a Uber Jar that can
be deployed either on a VPS or at the home server. This application exposes frontend on
the http port so the user, knowing VPS IP address can access app from anywhere and any
device. This app allows user to see on a map location of each of his drone, access their
video feed, talk from a drone loud speaker and manipulate each drone to perform
missions or FPV flights.
- Python, to build a drone control app that runs on a companion PC mounted on the
drone itself. On drone startup it automatically connects to the Java Control Station app
and constantly transmits drone telemetry data, video feed and also receives and executes
command coming from the Control Station.
- JavaScript, to write a single page application for our interactive user interface
We integrate all those applications to work together as a single cloud platform for remote
drone operations
By the end of this course, students not only learn a useful skills in Java, Python and
JavaScript, but most importantly, they see how all these technologies could work together
as one coherent distributed application that could easily have a real world usage.
Tech Stack:
Java / Python / JavaScript, Spring Boot, Sockets, Protobuf, Multi-threading, WebSockets,
MAVlink APIs, DroneKit framework, HTML/CSS, JQuery
