The Power of Many: Arduino Uno-Based Swarm Intelligence in Robotics

Description:

The main goal of this project is to build swarm intelligence robots in the course of the work. Arduino Uno with autonomous teamwork capabilities to tackle difficult problems with the help of decentralized communication and coordination.

In the realm of robotics, one concept that has garnered increasing attention is swarm intelligence. Unlike traditional robotics, where a single robot is programmed to perform specific tasks, swarm robotics leverages the power of multiple robots working together in a coordinated manner. At the heart of this approach lies Arduino Uno, a versatile microcontroller board that serves as the brain of these intelligent swarms.

Understanding Swarm Intelligence:

Swarm intelligence draws inspiration from nature, where collective behaviors observed in colonies of insects, flocks of birds, or schools of fish enable them to accomplish complex tasks without centralized control. Similarly, in robotics, swarm intelligence involves multiple robots (or agents) interacting with each other and their environment to achieve common goals.

The Role of Arduino Uno:

Arduino Uno serves as the cornerstone of swarm intelligence in robotics due to its flexibility, affordability, and ease of use. With its rich ecosystem of sensors, actuators, and communication modules, Arduino Uno enables robots to perceive their surroundings, communicate with one another, and make autonomous decisions in real-time.

Collective Decision-Making:

 One of the key advantages of swarm intelligence is its ability to facilitate collective decision-making. Rather than relying on a single decision-maker, each robot in the swarm contributes to the decision-making process based on local information and interactions with neighboring robots. This decentralized approach not only enhances the scalability of robotic systems but also improves their robustness and adaptability in dynamic environments.

Adaptive Behaviors:

 Another remarkable aspect of swarm intelligence is its capacity for adaptive behaviors. By continuously exchanging information and adjusting their actions in response to changing conditions, swarm robots can exhibit emergent behaviors that are greater than the sum of their individual parts. This adaptability allows swarm robotics systems to tackle a wide range of tasks, from exploration and search to monitoring and surveillance, with unparalleled efficiency and resilience.

Applications of Arduino Uno-Based Swarm Intelligence:

The applications of Arduino Uno-based swarm intelligence in robotics are diverse and far-reaching. In agriculture, swarm robots can collaborate to optimize crop management practices, such as planting, watering, and harvesting, leading to increased yields and reduced environmental impact. In disaster response scenarios, swarm robots can autonomously navigate hazardous environments, locate survivors, and coordinate rescue efforts, thus saving lives and minimizing risks to first responders.

Challenges and Future Directions:

Despite its promise, swarm intelligence in robotics still faces several challenges, including scalability, coordination, and robustness. Addressing these challenges will require advances in algorithms, hardware, and interdisciplinary collaboration. Looking ahead, the integration of artificial intelligence, machine learning, and swarm robotics holds tremendous potential for revolutionizing various domains, from manufacturing and logistics to healthcare and environmental monitoring.

Conclusion:

In conclusion, Arduino Uno-based swarm intelligence represents a paradigm shift in robotics, enabling robots to collaborate and adapt like never before. By harnessing the power of many, swarm robotics systems can accomplish tasks that would be impossible or impractical for individual robots alone. As we continue to unlock the full potential of swarm intelligence, the possibilities for innovation and discovery in robotics are truly limitless. More info

tested an ips tft display i have since ahh... spring. not so long ago ive got an idea to embody a scene from 8:11, when ryker got splashed with blood at the screen with leon.

its a wip now but i hope i would not be eaten by exams due this week..

heres more photos of display, but now in a dark.

less interesting - while writing the code it turned out that i didnt have the library i needed, which wasn't even in the built-in ide library search. so i went to github, and there it turned out that the library was outdated and in its place there was a new one (since 2020 ig), the version of which was already downloaded. i had to download the archive and upload it to ide to make everything work. also, i need to edit the program a little and clean it from unnecessary #includes, so there is no confusion.. and i also used a breadboard

Нет - это не гирлянда. Заливаю прошивку в умную розетку. Теперь она настолько умная что держит сайт и больше не дружит с китайскими облаками ( да и вообще с любыми кроме моего собственного)

Skaven warpstone lantern prototype!

Warning: flashing lights

Here's a little Arduino project I've been working on for my Skaven themed LARP group! It's a multifunctional lantern with three different modes, an unstable warp stone powered light, a standard flame lantern and a full bright white light for those late-night toilet runs.

I'm pretty proud of the warpstone effect, I made it so when the light dims the warpstone becomes unstable and starts crackling unpredictability as it tries to restabilize, then eventually once it destabilizes it glows more solidly and more brightly for a time before it fades and destabilizes again.

Anyone wanna see a dope robot my class made?

[ordinarymagician2000]

Today I fixed up my Mini-Hakkero prop for my cosplay!

Originally made it last year, but bringing it to cons ended up killing my terribly loose solder and crimp jobs for the admittedly janky internal wiring. For my fix I ended up having to skip 3 unreachable LEDs and attach new wires to the LED spiral (the shell stuck too much together and I could not reach under the battery holder anymore). A compromise, but one that ended up looking alright.

It's not the cleanest thing, but it was my first ever arduino project and with the new pattern i set up, it works decently enough as a cosplay prop :)

DIY Laser Tripwire Security System Using Arduino

The project consists of a laser module that continuously emits a beam aimed at a laser receiver sensor. When an object (such as a person) obstructs the laser, the receiver detects the interruption and triggers an alarm via a buzzer. This system is ideal for securing doorways, hallways, or any restricted area.

COMPONENTS REQUIRED

Laser LED Module

Laser Receiver Sensor Module

Buzzer

Jumper wires

Breadboard

Circuit Diagram

CODE

#define LASER_PIN 7  

#define RECEIVER_PIN 8  

#define BUZZER_PIN 9  

void setup() {

  pinMode(LASER_PIN, OUTPUT);

  pinMode(RECEIVER_PIN, INPUT);

  pinMode(BUZZER_PIN, OUTPUT);

  digitalWrite(LASER_PIN, HIGH); // Laser ON

  Serial.begin(9600);

}

void loop() {

  int status = digitalRead(RECEIVER_PIN);

  if (status == 1) {  // If laser beam is blocked

    Serial.println("⚠️ Intruder Detected!");

    digitalWrite(BUZZER_PIN, HIGH);  

  } else {

    Serial.println("✅ Area Secure");

    digitalWrite(BUZZER_PIN, LOW);  

  }

  delay(500);

}

Numpad Jr

My thinkpad doesn't have a numpad and could use something more portable than the average USB ones, so… just made one! Used Kailh square mouse buttons and an Arduino Pro Micro.

Sure, tactility's compromised due to size… but look at the cute lil' thingy lol.
