Swarm robots are a branch of robotics that draws inspiration from biological swarms to mimic their collective behavior. Automatic design methods are part of swarm engineering, depend on artificial intelligence algorithms to produce the collective behavior of robots. In general, they follow two-approach evolutionary algorithms like practical swarm optimization and reinforcement learning. This paper studies these approaches, illustrating the effect of modifications and enhancements of algorithms for both directions, showing important parameters considered for the best performance of the swarm, and explaining the methods and advantages of using deep learning to reinforcement learning.

The project presents the development of a system for monitoring environmental parameters. At the base of this system is the ESP-32S board that collects, processes and transmits data from the three sensors to the two web interfaces. The role of these web interfaces is to display the data collected from the sensors. The local web interface consists of two windows, the first window contains the table of sensors that displays the data measured by the sensors at that time. In the second window you can see the data measured by the sensors through graphs. They store the sensor data, giving the user the ability to view previously measured data. The local web interface provides sensor data only in the Wi-Fi network coverage area, and its data is deleted when the server is closed. The global web interface displays data using graphs. At the base of this web interface is the ThingSpeak platform that allows the system to transmit data anywhere in the world, store data in the Cloud space and the possibility of using special analysis functions.

This article introduces a basic LED control using the USB6001 hardware, which is a LabVIEW product. It may be thought of as an extension device for real-time testing of simulation results. LabVIEW2014 is the software used. TCP is the communication technique, which has already been incorporated in LabVIEW via one of the communication modules. It might also be done on the same platform. There are two objects in this article, a server and a client, that may transport data or messages between these two applications. The Transmission Control Protocol governs the transmission process.

The embedded operating system is a task-oriented computing platform that can be tailored, low-cost, and has high requirements for reliability and real-time performance. It plays an extremely important role in engineering applications. With the gradual application of embedded systems in various fields, the shortcomings of its insufficient ability to respond to security threats have gradually emerged, and many hackers have turned their attack targets into embedded systems. The important reason for these attacks is that embedded systems lack sufficient multi-layer protection mechanisms. This article focuses on the threats embedded systems face in terms of communication security. Then analyze the existing communication security-related technologies from the perspectives of the network layer, the transport layer, and the application layer. Finally, it summarizes the research direction of embedded system security countermeasures.
