How to enable wireless data transfer between arduino?

Question

Arduino

Good day to you, gentlemen!
Such a question arose, how to carry out wireless data transfer between arduino, namely data arrays, such as g-code.
To understand where and why this is all.
The task was set to implement a project demonstrating a swarm system, like in animals. The essence of the project will be that there is a guide robot that will go through the maze, find the shortest path and write it all into an array (like a map). Further, this array of coordinates is sent to other arduino robots and they immediately move along the shortest path, without any algorithms (except for regulators to position themselves relative to the walls).

Answer 1

I figured out how to implement your task, I’m writing the way I would do, I don’t pretend to optimize and novelty :)
Make each robot based on esp or arduino + wifi, set up access to a local server via wlan, receive, store and transmit to others on it data. In addition, if there are very large data arrays, the controller's capacity may not be enough to find the shortest path (this is for giant direct labyrinths), the calculation can be carried out on the server, and the robot can be given a ready route.
Thus, we launch a bunch of robots, in real time they transfer the route map to the server, it processes the data and the robots almost immediately receive the already formed route. And then they go to my house to kill for such nonsense. Joke. The idea is good, to look at ready-made implementations.
