Robots have become integral to modern society, especially amid the rapid pace of technological advancement. Their presence is felt in various facets of daily life, transforming how tasks are accomplished. This document serves as an informative overview, defining what robots are, categorizing them, and detailing the essential components that make up these machines. It is designed to be a valuable resource for students, complemented by accompanying slides that will deepen their understanding of the dynamic field of robotics.
The field of robotics encompasses the engineering discipline dedicated to the design, construction, operation, and application of robots. It focuses on creating machines capable of performing tasks autonomously—often with minimal or no human oversight—across a wide array of settings, including personal, industrial, commercial, and everyday environments.
Seven key types of robots, classified by their functions, play significant roles in various industries:
1. Autonomous Mobile Robots (AMRs)
These sophisticated robots are engineered to navigate and execute tasks independently, devoid of fixed routes. Utilizing advanced sensors and artificial intelligence, AMRs adeptly traverse their surroundings, skillfully avoiding obstacles and adapting to changing conditions. Their growing adoption in logistics, manufacturing, and other sectors allows them to efficiently manage tasks like transporting goods, overseeing inventory, and handling materials.
2. Automated Guided Vehicles (AGVs)
AGVs are self-propelled robotic vehicles designed to autonomously move materials within structured environments, such as warehouses and factories. By employing a range of navigation technologies—such as magnetic tape, painted lines, lasers, or cameras—AGVs follow predetermined paths, significantly reducing the need for human operators and enhancing operational efficiency.
3. Articulated Robots
Often referred to as six-axis robots or robotic arms, articulated robots are prevalent in many industrial applications. They are characterized by multiple joints that allow for an impressive range of movement and dexterity. Resembling the human arm, these robots excel in versatile tasks, including welding, assembly, and painting, delivering precision and efficiency in manufacturing processes.

4. SCARA Robots
The term SCARA stands for Selective Compliance Assembly Robot Arm, a specific type of industrial robot renowned for its speed and accuracy. SCARA robots are primarily employed in pick-and-place operations and assembly tasks, where rapid movement and precise alignment are crucial for successful outcomes.
5. Humanoid Robots
Humanoid robots are advanced artificial creations designed to mimic human form and function, enabling them to interact seamlessly with human environments and tools. Their applications span diverse fields, including research, space exploration, healthcare, education, and entertainment, showcasing their versatility and potential for human-like interaction.
6. Collaborative Robots (Cobots)
Cobots are exceptionally designed to work alongside humans in shared spaces. They are distinguished by their built-in safety features that facilitate direct human-robot interaction without the need for costly barriers. Cobots are particularly effective at performing repetitive, monotonous, or physically demanding tasks, allowing human workers to concentrate on more complex and creative responsibilities.
7. Hybrid Robots
The term “hybrid robot” can denote two main concepts: biohybrid robots, which merge living biological components with artificial robotic systems, and hybrid mobile robots, which incorporate various locomotion methods, such as combining wheels and legs for enhanced mobility.
Robots are revolutionizing industries by driving efficiency, streamlining processes, improving safety, and enriching user experiences across a multitude of applications.
Robots are increasingly integrated into various sectors, revolutionizing how tasks are performed by enhancing efficiency, precision, safety, and productivity.
Below are some significant applications of robots across key industries:
1. Manufacturing
In the manufacturing sector, robots play a vital role on assembly lines, especially in the automotive industry, where they handle tasks like welding, painting, and assembly with incredible accuracy. In electronics production, robots expertly carry out precision tasks, such as placing tiny semiconductor chips on circuit boards. Additionally, robots are utilized for packaging and labeling products, streamlining operations that require speed and consistency.
2. Healthcare
The healthcare industry has seen transformative advancements through robotic technology. Surgical robots, such as the da Vinci Surgical System, assist surgeons with minimally invasive procedures, enhancing precision and reducing recovery times for patients. Rehabilitation robots are employed in physical therapy to help patients regain movement and strength. Moreover, robotic prosthetics and exoskeletons provide individuals with mobility challenges the means to walk again. In hospitals, logistics robots streamline operations by efficiently delivering medications and supplies to various departments.
3. Space Exploration
In the realm of space exploration, robots have become indispensable. Mars rovers like Perseverance and Curiosity are equipped with advanced instruments for scientific research and exploration of the Martian terrain. In orbit, satellite maintenance and exploration robots are tasked with critical repairs and inspections. Furthermore, astronaut assistance robots, such as Robonaut, support human crews in various missions by performing tasks that might be too risky for humans in the harsh environment of space.
4. Defense and Security
Robots are playing a crucial role in enhancing defense and security operations. They are used for bomb disposal and handling hazardous materials, ensuring the safety of personnel in dangerous situations. Surveillance drones and patrolling robots monitor areas for security threats, providing real-time intelligence. Additionally, autonomous military vehicles and robotic guards offer enhanced protection and situational awareness on the battlefield.
5. Agriculture
The agriculture sector is experiencing a technological revolution with the introduction of robots. Automated tractors and harvesters increase efficiency in planting and gathering crops. Drones are employed for crop monitoring, analyzing health, and even spraying pesticides with precision. Weeding and planting robots are gaining traction, helping farmers manage fields more effectively while reducing labor costs.
6. Service Industry
In the service industry, robots are transforming customer experiences. Cleaning robots, like the Roomba, autonomously vacuum floors while minimising human effort. Reception and hospitality robots are increasingly found in hotels and shopping malls, assisting guests and providing information. Food delivery robots are now making their way through neighborhoods, while cooking robots are designed to prepare meals with minimal supervision.
7. Logistics and Warehousing
The logistics and warehousing sectors are heavily reliant on automation. Automated guided vehicles (AGVs) efficiently transport goods within warehouses, reducing the manual handling of products. Robotic arms are utilized for sorting and packing items, ensuring speed and accuracy in fulfilling orders. Inventory robots also play a pivotal role by monitoring stock levels and helping maintain optimal inventory.
8. Research and Education
In research and education, robots facilitate a vast array of tasks. Lab automation robots streamline experiments, enabling scientists to focus on analysis rather than manual work. Educational robots are designed to teach coding and robotics to students of all ages, fostering interest and skills in technology. Additionally, robots are being deployed for scientific exploration in challenging environments such as deep oceans or hazardous laboratories.
9. Household Use
At home, robots are becoming invaluable companions. There are robots designed for vacuuming, window cleaning, and lawn mowing, making household chores easier than ever. Companion robots provide support for the elderly, offering companionship and assistance for daily activities, while entertaining them when needed.
10. Entertainment and Arts
The entertainment industry has embraced robotics as well. In theme parks and shows, robots create engaging experiences for visitors, enhancing the overall entertainment value. AI-powered performers, from musicians to dancers, showcase impressive talents, while other robots contribute to creating unique art, music, or storytelling content, blending technology with creativity in new and exciting ways.
