Robotics is an exciting and rapidly growing field, but it’s also surrounded by plenty of myths and misconceptions. From the idea that robots will one day take over the world to the belief that all robots are powered by artificial intelligence, there’s a lot of confusion about what robots can actually do. By exploring some of the most common myths about robotics, we can better understand the real-world capabilities of these fascinating machines and how they’re shaping our future—without all the sci-fi drama!
Robots will replace all human jobs
This is one of the most prevalent myths. Robots are designed to assist and automate specific tasks, particularly repetitive, dangerous, or precision-based ones, but they cannot replace human intuition, creativity, and adaptability. In fact, as robots take over mundane or hazardous jobs, humans are freed to focus on more complex, strategic roles, such as design, oversight, and creative problem-solving. New jobs are also emerging in robotics maintenance, programming, and AI training, which require human expertise.
Robots are intelligent
Intelligence in robotics is artificial, meaning robots can only process data and execute tasks they are specifically programmed for. The algorithms that enable robots to make decisions or perform tasks are far from true intelligence or consciousness. They rely on data inputs and pre-defined logic to operate, lacking self-awareness, understanding, or the ability to reason like humans. Robots are as “smart” as the engineers and data they are given to work with.
Robots have feelings
While advancements in AI have led to robots simulating emotions through voice tone, facial expressions, or reactions to certain stimuli, these are merely programmed behaviors. Emotions are a human experience, rooted in biology, and while robots may mimic empathy in customer service or caregiving roles, they do not experience feelings as living beings do. Their “emotions” are simply programmed responses.
All robots are humanoid
Most robots do not resemble humans. The form of a robot depends entirely on its purpose. Industrial robots, for example, are often stationary arms designed to weld, assemble, or paint, while service robots may have wheels, tracks, or even spider-like legs for mobility. Only a small subset of robots, called humanoid robots, are designed to imitate the human form, often for research in human-robot interaction.
Building robots is only for experts
Thanks to open-source platforms, easy-to-use robotic kits, and comprehensive tutorials, building a basic robot is now possible for beginners, students, and hobbyists. Modern microcontrollers like Arduino and Raspberry Pi allow for simple and accessible robotics projects, requiring little to no prior experience. Robotics is increasingly being introduced to younger audiences as a way to foster interest in STEM fields.
All robots are expensive
While industrial robots and advanced AI systems can indeed be costly, there are plenty of affordable robotic kits available for educational and hobbyist purposes. For instance, basic kits for building line-following or obstacle-avoiding robots can be bought for under $50, and the components for building custom robots are widely available at low cost. The rise of 3D printing has further reduced the cost of custom parts.
Robots are always complex
Not all robots are built for complex tasks. Some robots have simple designs and functionalities, like those used in warehouses for sorting, or vacuum robots that only clean floors. Complexity in robotics scales with the intended use, so while some robots are incredibly sophisticated, many perform simple, repetitive functions efficiently without the need for intricate programming or design.
Robots can fix themselves
While some research focuses on creating robots that can perform self-repair (for example, through modular designs or self-healing materials), this is not the standard. Most robots rely on human intervention for repairs and maintenance. Diagnostic systems can alert humans to faults, but robots generally do not have the autonomy or tools to physically repair themselves, especially for mechanical or electrical failures.
Robots can think like humans
Human cognition is deeply complex, involving emotional, moral, and creative dimensions that robots cannot replicate. A robot’s “thinking” is limited to processing inputs according to predefined algorithms. Even advanced AI-based robots like those used in machine learning are still bound by the data they are trained on. They may be able to solve specific problems, but their capabilities are narrow and task-specific.
Robots will take over the world
This myth has been perpetuated by science fiction for decades, from “Terminator” to “The Matrix.” In reality, robots are tools created by humans to perform specific tasks. The idea of robots rebelling or taking over is not feasible, as robots operate based on programming and cannot develop independent agendas or desires. Control over robots and AI remains firmly in human hands through regulations, ethical programming, and ongoing supervision.
Robots don’t make mistakes
Although robots are built to be precise, they are not infallible. Robots can malfunction due to software bugs, hardware failures, or unexpected environmental factors. They may also interpret input data incorrectly or fail to adapt to changes in their environment. In fields like manufacturing, small deviations from specifications can lead to significant issues, which is why human oversight and error-checking are critical.
Robots are always faster than humans
In tasks requiring precision or repetition, robots excel at maintaining high speeds and consistency. However, in situations where adaptability, dexterity, or complex decision-making is required, humans often outperform robots. For example, certain fine motor skills in surgical procedures or delicate craftsmanship tasks can still be performed faster and more effectively by humans.
You need a PhD to work with robotics
While a PhD can open doors to advanced research in robotics, the field is increasingly accessible to enthusiasts and professionals without advanced degrees. Many industries require technicians, software developers, and hardware engineers who can work with robots but do not necessarily need a deep theoretical background. Numerous online courses, certifications, and bootcamps offer hands-on learning opportunities to enter the field without a PhD.
All robots need to be programmed from scratch
Pre-built software libraries, APIs, and frameworks have simplified the programming of robots, allowing developers to build upon existing code instead of starting from scratch. Tools like ROS (Robot Operating System) offer a collection of software frameworks and functions that can be integrated into robotic systems, significantly reducing the need to code every function manually.
Robots are always made of metal
Many robots are constructed from a combination of materials suited to their task. Lightweight plastics, rubber, carbon fiber, and silicone are often used for mobile robots or those requiring flexibility. For instance, soft robotics utilizes elastic materials to create flexible, adaptive robots that can grip objects gently, mimicking biological structures.
Only engineers can build robots
While engineers play a central role in the design and development of robots, robotics is a multidisciplinary field that involves input from computer scientists, artists, designers, psychologists, and even ethicists. For instance, the design of humanoid robots often requires input from specialists in anatomy and human interaction to ensure the robot moves and communicates effectively with humans.
Robots can feel pain
Pain, as experienced by living beings, is a biological response to harmful stimuli. Robots, on the other hand, can detect damage or malfunction through sensors, but they do not “feel” in the emotional or biological sense. A robot’s system might signal the need for repair or shutdown due to an error, but this is purely a functional, mechanical response, not an emotional one.
Robots can instantly learn new skills
Robots, particularly those powered by AI, require training and programming to learn new skills. Even machine learning algorithms, which allow robots to adapt to new tasks through experience, require significant amounts of data, time, and computational power to develop proficiency. Robots do not “magically” learn new tasks but must go through rigorous training processes similar to how humans learn but within their specific domain.
Robots can solve any problem
A robot’s capabilities are constrained by the algorithms it runs and the hardware it uses. While robots excel at repetitive, rule-based tasks, they struggle with open-ended, creative problem-solving that requires intuition and adaptability. For example, a robot programmed to play chess can’t bake a cake unless it is reprogrammed or equipped with entirely different modules designed for the new task.
Robots are always futuristic-looking
Robots are often imagined as sleek, humanoid machines with advanced features, but in reality, many robots are utilitarian and designed specifically for their function, without any focus on aesthetics. For example, industrial robots are typically large, metallic arms with no attempt to make them look futuristic. In contrast, robots designed for consumer interaction, like robotic pets or humanoid assistants, may adopt more stylized designs to appear approachable.
Robots can replace human creativity
Creative problem-solving, innovation, and artistic expression are inherently human traits, deeply tied to emotion and subjective experience. While robots can generate music, art, or design through algorithms, the creative process in humans involves factors like inspiration, intuition, and personal experience, which robots cannot replicate. Robots can assist in creative tasks by automating repetitive aspects or providing new perspectives, but they do not possess creativity in the same way humans do.
All robots have AI
Not all robots are equipped with artificial intelligence. Many robots function purely based on pre-programmed logic or simple automation routines. For instance, robotic arms in manufacturing plants operate through strict programming, moving according to specific instructions without any need for AI. AI is typically used when a robot must interact with dynamic environments or make decisions based on changing data.
Robots are a recent invention
The concept of automata (self-operating machines) dates back thousands of years. Ancient civilizations built mechanical devices that could mimic certain human or animal behaviors. For example, the ancient Greeks had mechanical statues, and the 11th-century Islamic scholar Al-Jazari developed water-powered automatons. The modern concept of a robot, however, emerged in the 20th century, particularly with the rise of computers and automation.
All robots are autonomous
Not all robots operate independently. Many robots require human control, often through remote systems or semi-autonomous setups. Drones, for instance, may have autonomous features like altitude control, but they often rely on human operators for navigation or mission execution. Telepresence robots allow humans to remotely control the robot’s actions, particularly in scenarios where autonomy is either not possible or not desirable, such as in hazardous environments or precise operations.
Robots are only used in factories
While robots initially gained popularity in industrial automation, their applications have expanded far beyond the factory floor. Robots are now used in healthcare (surgical robots, rehabilitation robots), agriculture (harvest and planting robots), entertainment (robotic performers, amusement parks), exploration (space, deep sea), and even in households (vacuum robots, lawn-mowing robots). Each industry adapts robotic technology to its specific needs.
Robots can make moral decisions
Robots are inherently incapable of making moral or ethical judgments. They follow programmed instructions and cannot discern right from wrong. Even robots using advanced AI can only simulate decision-making processes based on algorithms, which are inherently amoral. Ethical dilemmas, such as determining the best course of action in complex situations like healthcare or warfare, still require human oversight. In fields like autonomous vehicles, designers implement safety protocols and decision-making algorithms, but these are pre-programmed responses, not genuine ethical reasoning.
Robots are indestructible
While robots can be engineered to withstand harsh environments, no robot is truly indestructible. They are vulnerable to wear and tear, corrosion, impact damage, and software issues. Robots designed for industrial use often need regular maintenance to ensure proper functioning, and those used in extreme environments (like space exploration or deep-sea missions) are subject to technical failures and environmental limitations.
Robots don’t need humans anymore
Even the most advanced robots still depend on humans for development, programming, and maintenance. While autonomous systems have improved, they still require human intervention for complex decision-making, repairs, and upgrades. Robots also rely on humans to define their tasks, goals, and operational limits. For instance, AI systems might process data on their own, but humans are needed to set the initial objectives and interpret the results.
Robots can read your mind
This myth is rooted in science fiction. While brain-computer interface (BCI) technology is making strides in allowing humans to control devices with their thoughts, the idea that robots can “read minds” is far from reality. BCI relies on detecting electrical signals in the brain and translating them into commands, but this is a far cry from the kind of mind-reading abilities often depicted in movies. Robots can’t interpret thoughts, emotions, or intentions without explicit input through sensors or commands.
Robots are dangerous to humans
While robots can pose a risk if not properly designed or used, most are built with safety features to minimize harm. In industrial settings, robots are often equipped with sensors to detect human presence and stop operations to prevent injury. Collaborative robots, or “cobots,” are specifically designed to work alongside humans safely. Additionally, robots in service sectors, like healthcare or hospitality, are programmed with stringent safety protocols to ensure they don’t cause harm.
Robots will eventually evolve on their own
Evolution is a biological process driven by natural selection, and robots do not “evolve” in the same way. Their development is entirely dependent on human engineers and researchers who update software, design new hardware, and introduce new functionalities. While machine learning allows robots to “improve” their performance through experience, this is not the same as evolution, as it still relies on human-provided data and algorithms.
Robots are emotionless workers
While robots don’t have emotions, advancements in AI have enabled some robots to simulate emotional responses. For instance, social robots designed for customer service or companionship can interpret facial expressions and tone of voice, responding in ways that appear empathetic. This is particularly useful in applications like elderly care, where emotional engagement can improve user experience. However, this emotional interaction is artificial—robots don’t “feel” anything; they just respond based on pre-programmed patterns.
Robots are magic machines
Many people view robots as almost magical, especially when they perform complex tasks autonomously. However, robots are fundamentally machines driven by algorithms and physics. Every movement, action, or decision a robot makes is based on pre-programmed instructions or data-driven algorithms. There’s no mystery to how they work—just careful engineering and sophisticated programming that harness modern technology.
You can make a robot with any materials
While creativity is encouraged in robotics, you can’t just use any materials to build a robot. The choice of materials depends on the robot’s function and environment. For instance, industrial robots require sturdy metals for durability and strength, while mobile or soft robots may use lightweight plastics or silicone for flexibility. Electronic components like sensors, actuators, and processors must also be carefully integrated, as improper materials can lead to malfunctions or inefficiency.
Robots are a single technology
Robotics is actually an interdisciplinary field that combines various areas of technology, including mechanical engineering, electrical engineering, computer science, artificial intelligence, control systems, and more. Building a robot requires knowledge of how to integrate sensors, actuators, control algorithms, and communication systems. It’s the convergence of these fields that gives robots their functionality and versatility.
Robots can repair other robots
Although there are projects exploring self-repairing or modular robots, it’s far from mainstream. Most robots require human intervention for repairs. While robots might assist in diagnostics or maintenance tasks, human oversight and control are usually necessary. Robotic systems designed to operate in hazardous environments might include redundancy or modularity, where damaged parts can be replaced, but these systems are still far from being fully self-sufficient.
All robots can walk
Walking is one of the most complex forms of locomotion for robots to achieve. Many robots, especially industrial or service robots, use wheels or tracks for movement because these systems are simpler, more efficient, and less prone to failure. Walking robots, particularly bipedal ones, must maintain balance, navigate uneven surfaces, and deal with complex dynamics, which require advanced control systems and algorithms. As a result, walking robots are still a niche subset, often used in research or specialized applications.
All robots have arms
Many robots don’t have arms because their tasks don’t require manipulation of objects. For instance, vacuum cleaning robots, warehouse inventory robots, or drones don’t need arms to perform their designated functions. Robots are designed with the most efficient structure to carry out their intended task, and arms add complexity, cost, and power requirements that aren’t always necessary.
Robots are superhumans
Though robots can outperform humans in specific tasks, like precision assembly, data analysis, or heavy lifting, they are not “superhuman.” Robots lack the general adaptability, creativity, and problem-solving ability that humans possess. Robots can also malfunction and make mistakes if their environment changes in ways their programming doesn’t account for. In many areas, humans remain more versatile, capable of adapting to unexpected situations.
Robots will become our overlords
The fear of robots turning against humans and taking over society is a popular narrative in science fiction, but it is not grounded in reality. Robots and AI are tools created and controlled by humans. Any power they hold is limited to the tasks we assign them, and they lack autonomy beyond their programming. Ethical AI development, governance, and safety standards ensure that robots and AI systems are kept under human control, with strict limitations on their capabilities.
All robots have cameras for vision
While cameras are a common sensory tool in robotics, especially for visual recognition or navigation tasks, not all robots use cameras for sensing. Many robots rely on other types of sensors, such as infrared, ultrasonic, LiDAR, or tactile sensors, depending on their task. For example, some autonomous vehicles use LiDAR to create a 3D map of their surroundings, and robots used for object manipulation may rely more on touch sensors than visual inputs.
Robots have humanlike brains
A robot’s “brain” is typically a computer processor or microcontroller, which runs software and processes inputs based on predefined algorithms. These systems can perform calculations and follow logic patterns, but they are not at all like human brains, which involve complex biochemical processes, emotions, and consciousness. Even the most advanced AI systems, which can mimic certain cognitive functions, are far from replicating human thought processes in their entirety.
Robots are self-aware
Self-awareness means being able to see yourself as a unique person, different from other people and your surroundings. No robot or AI system has reached this level of consciousness. While robots can be programmed to act autonomously, detect obstacles, or even identify their own components, they do not have any sense of self. Current research in AI is far from achieving anything resembling true self-awareness.
You can build a robot in a day
While it’s possible to assemble simple robots in a short time using kits or pre-built components, building a fully functional, complex robot from scratch can take weeks, months, or even years. Factors such as mechanical design, electronics integration, software development, and testing require time and iteration. Even experienced teams may take significant time to refine a robot for specific tasks or environments.
Robots can do anything
Robots are typically designed for specific tasks and are optimized to perform those tasks efficiently. They are not universally adaptable to all situations like humans. For example, a robot built for welding in a factory cannot suddenly be reprogrammed to assist in surgery without a complete overhaul of its design, software, and functionality. Robotics systems are highly specialized tools, and while some are versatile, they are still far from being universally applicable.
Robots are only for men
Historically, STEM fields, including robotics, have been male-dominated, but this is changing rapidly. Women play crucial roles in robotics research, engineering, and leadership across industries. Organizations and educational programs are increasingly encouraging women to enter the field of robotics, leading to greater diversity. Women have been pioneers in AI, automation, and robotics, and their contributions are essential to the future of these technologies.
Robots will make humans obsolete
Rather than replacing humans, robots are more likely to augment human capabilities. In fields like healthcare, manufacturing, and agriculture, robots take on repetitive tasks, allowing humans to focus on more complex, creative, and strategic activities. Instead of making humans obsolete, robots create new opportunities for collaboration, where humans and machines work together to achieve greater efficiency and productivity. In many cases, robots enhance human capabilities, extending our ability to perform tasks that would be too dangerous or labor-intensive.
Robots don’t need maintenance
Robots, like all machines, require regular maintenance to function properly. Components wear out over time, sensors need calibration, software requires updates, and sometimes mechanical parts need replacement. Without proper maintenance, even the most advanced robots can malfunction or become inefficient. Maintenance is a crucial aspect of robotic systems, especially in industries where downtime can lead to significant productivity losses.
All robots are controlled by AI
Not all robots rely on artificial intelligence. Many robots operate using pre-programmed algorithms and respond to simple inputs or environmental triggers without any AI involvement. For example, robotic arms in factories follow specific motion sequences and don’t need to “learn” or adapt to new data. AI is typically used in applications where robots must process large amounts of data, interact with humans, or adapt to changing environments.
Robots are always reliable
While robots are designed for precision and consistency, they are not infallible. Robots can malfunction due to software bugs, hardware failures, or unforeseen environmental conditions. Even advanced AI systems can make errors, especially when confronted with situations outside their training data. This is why human oversight is often required, especially in critical tasks like healthcare, space exploration, or autonomous driving. Backup systems and regular monitoring are necessary to ensure reliability.

Robots might seem like something out of a sci-fi movie, but when you look beyond the myths, the reality is just as fascinating! While they’re incredible at certain tasks, robots aren’t here to replace humans, take over the world, or read our minds. They’re powerful tools we’ve built to help with specific jobs, but they still need us to program, maintain, and guide them. So, next time you think of robots, remember that while they’re impressive, they’re not magical—they’re a result of human ingenuity, working with us, not against us.
