The Science of Robotics: How Robots Are Made and How They Work Introduction The field of robotics has advanced rapidly, becoming an integral part of modern society. Robots have moved beyond industrial use into healthcare, military, space exploration, and even personal life. From autonomous drones and robotic vacuum cleaners to life-saving surgical robots, their versatility and efficiency are revolutionizing multiple sectors. As technology evolves, robots become more intelligent, autonomous, and capable of performing complex tasks that benefit humanity. This article delves into the science of how robots are made and how they work, covering their components, engineering processes, applications, and the critical role artificial intelligence (AI) plays in shaping robotic systems. I. What is a Robot? Definition and Classification A robot is a programmable machine designed to carry out tasks autonomously or semi-autonomously, often performing tasks that are either repetitive, dangerous, or beyond human capability. There are several classifications of robots based on their function and design: Basic Characteristics of Robots Regardless of the specific classification, all robots share three core characteristics: II. The Components of a Robot Robots are composed of several key components, each contributing to their overall functionality. 1. Sensors Sensors act as the “eyes” and “ears” of a robot, collecting data from the environment. Types of sensors include: 2. Actuators Actuators serve as the “muscles” of a robot, converting electrical or mechanical energy into movement. They drive components such as wheels, robotic arms, or even legs. Common types of actuators include: 3. Control System (Brain) The control system is essentially the robot’s “brain,” consisting of a central processor or microcontroller. It executes software programs that control the robot’s actions, making real-time decisions based on the data received from sensors. AI and machine learning can further enhance the robot’s ability to make complex decisions and adapt to changing environments. 4. Power Supply A robot’s power supply is critical to its functionality. Different robots use various power sources: 5. End Effectors End effectors are the tools or attachments that a robot uses to interact with the world. These can be simple grippers, welding torches, or even surgical instruments. End effectors are often customizable to perform specific tasks in industries like healthcare or manufacturing, allowing robots to handle fragile objects or manipulate heavy machinery. III. How Robots Are Made: The Engineering Process Creating a functional robot involves multiple stages of engineering, from design to assembly and programming. 1. Designing the Robot The process begins with designing the robot’s structure and systems. Robotics engineers use Computer-Aided Design (CAD) software to create detailed blueprints of the robot, considering its purpose, mobility, and operational environment. For instance, a robot designed for underwater exploration will differ greatly from a robot built for factory automation in terms of materials, mobility, and power systems. 2. Building the Frame (Chassis) The robot’s frame is its skeletal structure, which supports its components and enables movement. Lightweight materials like aluminum or carbon fiber are often used to ensure durability without compromising on mobility. 3. Assembling Mechanical Components The next step involves assembling the motors, actuators, and other mechanical components. This process can be complex, particularly when creating precision tools like robotic arms for surgery or robotic grippers that handle delicate objects. Ensuring proper alignment and calibration of moving parts is crucial for the robot’s overall functionality. 4. Wiring and Electronics Wiring the robot involves connecting sensors, cameras, and control systems. Engineers ensure proper communication between the control system and the mechanical components by testing connectivity and diagnosing any potential errors during assembly. 5. Programming Once the hardware is assembled, software engineers write the code that dictates the robot’s actions. Robots are programmed using languages such as Python, C++, or specialized platforms like Robot Operating System (ROS). These programs translate user commands into specific movements and tasks. Programming is also where AI algorithms are incorporated, allowing robots to process sensor data, make decisions, and even learn over time. IV. How Robots Work: Key Functions and Processes Once built, robots operate through a series of functions that allow them to perceive their environment, move, and interact with the world. 1. Perception Robots use their sensors to perceive the world around them, converting raw data into actionable information. For example, autonomous vehicles use LIDAR, radar, and cameras to detect obstacles and plot routes. Similarly, robotic vacuums scan rooms to create a map for efficient cleaning. 2. Movement and Mobility Robots employ different movement mechanisms, including wheels, legs, or even propellers (in the case of drones). Each movement system is suited to specific environments. Drones fly using propellers and gyroscopes for stabilization, while legged robots like Boston Dynamics’ Spot can traverse uneven terrain. 3. Interaction with the Environment Robots use their end effectors to interact with objects or their surroundings. For example, manufacturing robots equipped with welding torches perform precise welds on assembly lines, while surgical robots like da Vinci perform delicate operations in healthcare settings. AI enhances these interactions by improving precision and adaptability. 4. Autonomy and Decision-Making Autonomous robots leverage AI to make decisions without human intervention. This includes everything from drones adjusting their flight path to avoid obstacles to industrial robots that can detect and compensate for production line errors. V. The Role of Artificial Intelligence in Robotics 1. Machine Learning and Robotics AI, particularly machine learning, plays a pivotal role in making robots smarter and more capable. Machine learning algorithms allow robots to learn from experience, improving their performance over time. For instance, robots used in warehouses can learn to optimize their routes for picking and packing goods, reducing time and errors. 2. AI-Powered Vision and Sensing AI enhances the way robots perceive their environment. Through computer vision algorithms, robots can identify objects, track movement, and make intelligent decisions. For example, medical robots can analyze imaging data to identify abnormalities such as tumors, while AI-powered drones can create detailed maps of landscapes for military or agricultural purposes. VI. Applications of Robots in the Real World 1. Manufacturing Industrial robots are transforming manufacturing, handling repetitive tasks with unmatched

Omegle, a popular website that allowed people to chat, talk and interact with strangers from all over the world, has shut down after 14 years. The website’s owner- Leif K-Brooks, said he made the decision because “stress and expense of operating Omegle, and fighting its misuse – are simply too much.” Founded in 2009, Omegle was a platform that allowed users to interact with random people on the internet without having to reveal any details about themselves. The anonymous online chat service did not require users to register to chat, which might be one of the reasons why the service gained massive popularity. The online chat service saw an increase in usage during the COVID-19 pandemic, as many people were stuck in the vicinity of their homes and couldn’t talk or meet with others. Omegle users could choose if they want to engage with strangers via text, voice or videos. The platform also had an ‘Add your interests’ option where people could narrow down their search to meet people with similar interests. However, the online chat service often found itself in hot waters, with users often complaining about paedophilia, racism, abuse and sexism. In the last few years, Omegle has also seen a multi-fold rise in child sex abuse and nudity. While Omegle tried to fix the issue by introducing moderated chat rooms, working with law enforcement agencies and increasing the minimum age limit from 13 to 18 years, the problem was that there was no age verification process and most people engaged in nudity and racism faced no consequences. Omegle, a chat service that pairs users with a random person so they can talk via text or video, is shutting down. Leif K-Brooks, who launched the service when he was 18 years old, announced its closure and talked about its humble beginnings, as well as how it grew organically because “meeting new people [is] a basic human need.” While he didn’t delve into the specific reasons for Omegle’s shutdown, he admitted that “some people misused [the service], including to commit unspeakably heinous crimes.” Critics have raised concerns about the website’s safety over the past years, with some even calling it a “magnet for pedophiles.” In 2021, an American woman sued the website for pairing her with a person who coerced her into sending explicit images for three years, starting when she was just 11 years old. Her legal team said that the way the platform works allows it to become a “hunting ground for predators.” Last year, two men in the US were sentenced to federal prison for exploiting children they met on apps, including Omegle, forcing them to perform sexual acts and to send them explicit photos and videos. A BBC investigation also revealed a rise in cases of users exposing themselves on Omegle chat. These users included minors, because while the website is technically meant for use by people 18 and older, it has no age verification in place. In his farewell note, K-Brooks said he worked with law enforcement agencies, as well as “the National Center for Missing and Exploited Children, to help put evildoers in prison where they belong.” His website, he said proactively collected evidence against these people and tipped authorities to put them in jail. However, he said the fight against crime is “a never-ending battle” and that the “world has become more ornery” in recent years. He also said that there’s been “a constant barrage of attacks on communication services… based on the behavior of a malicious subset of users.” In the end, he found the “existing stress and expense of operating Omegle, and fighting its misuse” to no longer be sustainable, both financially and psychologically. “Frankly, I don’t want to have a heart attack in my 30s,” he added.
