Robotics: How Machines Can Sense, Think, and Act
Robotics: What You Need to Know
Robotics is the science and engineering of designing, building, programming, and operating machines that can perform tasks that are normally done by humans or animals. Robotics is a fascinating field that has many applications in various domains such as healthcare, manufacturing, logistics, education, entertainment, and more. Robotics also poses many challenges and opportunities for society, economy, environment, ethics, and security.
In this article, we will explore the different types and applications of robots, the main challenges and opportunities for robotics development, and the future of robotics. We will also answer some frequently asked questions about robotics at the end of the article.
Types of Robots
Robots come in different shapes, sizes, functions, and levels of autonomy. Depending on how they move, interact, sense, think, and perform tasks, we can classify robots into six main types: autonomous mobile robots (AMRs), automated guided vehicles (AGVs), articulated robots, humanoid robots, collaborative robots (cobots), and hybrid robots. Let's look at each type in more detail.
Autonomous Mobile Robots (AMRs)
AMRs are robots that can move freely in an environment without following predefined paths or relying on human guidance. They use sensors, cameras, and artificial intelligence (AI) to perceive their surroundings and make decisions on how to navigate obstacles, avoid collisions, and reach their destinations. Some examples of AMRs are self-driving cars, delivery drones, and warehouse robots.
AMRs have many advantages such as increasing efficiency, reducing human errors, and improving safety. However, they also have some disadvantages such as high cost, complexity, and unpredictability.

Automated Guided Vehicles (AGVs)
AGVs are robots that move along fixed tracks or predefined paths using sensors, magnets, or wires. They require human input or supervision to operate. They are often used to transport materials or goods in controlled environments such as factories, warehouses, or airports. Some examples of AGVs are forklifts, trolleys, and trains.
AGVs have many advantages such as simplicity, reliability, and scalability. However, they also have some disadvantages such as low flexibility, limited adaptability, and dependency on human intervention.
Articulated robots are robots that have jointed arms or legs that can bend and rotate in multiple directions. They are often used to perform tasks that require precision, speed, or flexibility such as welding, painting, assembling, or picking and placing. Some examples of articulated robots are industrial robots, surgical robots, and robotic arms.
Articulated robots have many advantages such as high accuracy, versatility, and dexterity. However, they also have some disadvantages such as high maintenance, complexity, and safety risks.
Humanoid robots are robots that resemble the human body in appearance and behavior. They have a head, torso, arms, legs, and sometimes hands and feet. They can walk, talk, gesture, and interact with humans and other robots. Some examples of humanoid robots are Sophia, Pepper, and Atlas.
Humanoid robots have many advantages such as natural communication, social interaction, and human-like skills. However, they also have some disadvantages such as high cost, ethical issues, and technical challenges.
Collaborative Robots (Cobots)
Cobots are robots that work alongside humans in a shared space or task. They are designed to be safe, friendly, and adaptable. They can sense human presence and actions and adjust their behavior accordingly. They can also learn from human feedback and improve their performance over time. Some examples of cobots are Baxter, Sawyer, and YuMi.
Cobots have many advantages such as enhancing productivity, quality, and creativity. However, they also have some disadvantages such as limited autonomy, liability issues, and social implications.
Hybrid robots are robots that combine features or functions of two or more types of robots. They can switch between different modes of operation depending on the situation or task. They can also integrate different sensors, actuators, and controllers to achieve optimal performance. Some examples of hybrid robots are snake robots, flying cars, and amphibious robots.
Hybrid robots have many advantages such as increased functionality, adaptability, and robustness. However, they also have some disadvantages such as increased complexity, cost, and difficulty of integration.
Applications of Robotics
Robotics has many applications in various domains that can benefit from automation, intelligence, and interaction. Here are some of the most common and promising applications of robotics in different sectors:
Robotics is transforming the healthcare industry by providing new ways of delivering care, diagnosis, treatment, and rehabilitation. Robots can assist doctors, nurses, and patients in various tasks such as surgery, therapy, monitoring, drug delivery, and prosthetics. Some examples of robotics in healthcare are da Vinci surgical system, Paro therapeutic robot, and ReWalk exoskeleton.
Robotics in healthcare has many benefits such as improving quality, efficiency, and accessibility of care. However, it also has some risks such as ethical dilemmas, human error, and cyberattacks.
Robotics is revolutionizing the manufacturing industry by enabling new levels of productivity, quality, and flexibility. Robots can perform tasks that are repetitive, dangerous, or difficult for humans such as assembly, welding, painting, and inspection. Some examples of robotics in manufacturing are KUKA industrial robots, Fanuc assembly robots, and ABB painting robots.
Robotics in manufacturing has many benefits such as reducing costs, waste, and accidents. However, it also has some risks such as job displacement, skill gap, and environmental impact.
Robotics is transforming the logistics industry by providing new ways of managing and moving goods and materials. Robots can handle tasks that are labor-intensive, time-consuming, or complex for humans such as warehousing, delivery, inventory, and sorting. Some examples of robotics in logistics are Amazon warehouse robots, Starship delivery robots, and Fetch inventory robots.
Robotics in logistics has many benefits such as increasing speed, accuracy, and customer satisfaction. However, it also has some risks such as legal issues, security threats, and social concerns.
Robotics is enhancing the education industry by providing new ways of teaching and learning. Robots can act as tutors, mentors, or companions for students and teachers in various subjects such as STEM (science, technology, engineering and math), languages, arts, and social skills. Some examples of robotics in education are NAO, KIBO, and Cozmo.
Robotics in education has many benefits such as improving motivation, engagement, and outcomes. However, it also has some risks such as privacy issues, ethical challenges, and pedagogical limitations.
Robotics is enriching the entertainment industry by providing new ways of creating and enjoying content. Robots can act as performers, artists, or gamers for humans and other robots in various forms such as music, art, and sports.
