Introduction
In just a few months, scenes of humanoid robots walking steadily, picking up boxes, and moving containers inside huge warehouses have become part of the digital daily: amazing short clips on platforms, followed by news of employment contracts, paid experiments, and quantum production plans.The irony is that for almost two decades this particular category has been synonymous with deferred promises: expensive mechanical bodies that stumble over things that seem intuitive to humans, turning into research projects, conference presentations or promotional videos without frequent use in a real work environment. So the question returns not only as a technical curiosity but also as an anachronism: Why now? What has changed technologically, economically and socially for robots to move from deferred promise to job candidate?
Part of the answer is in the numbers. TheInternational Federation ofRobotics ' WorldRobotics 2025reportstates that industrial robot installations reached 542,076 units in 2024 (the second-highest number historically), while global operational inventory reached 4,663,698 robots actually working in factories.Meanwhile, sales of professional service robots rose to over 199,000 units in 2024, with a 14% jump in the transportation and logistics category, and RaaS fleets growing 31% to over 24,500 units (International Federation of Robotics, 2025b).
The return of robots is not a sudden surge, but the result of the confluence of three forces: the maturation of artificial intelligence, the pressure of economic reality, and the changing structure of work. This paper deconstructs how robots came out of their comfort zone, why factories and warehouses need them, and why 2025 seems to be an inflection point when AI meets the mechanical body.
Second: From spectacle to function - how did humanoid robots get out of the spotlight?
If we go back a couple of decades, the issue was not a lack of ideas, but a lack of operating conditions. The humanoid robot was successful in showcase moments: a few minutes of walking, a hand gesture in front of an audience, and that was it. In a real working environment, limitations were multiplying: limited batteries, unstable motor control that makes falling a constant possibility, and rigid programming that breaks down with small changes in the position of a box or an unexpected light reflection or noise.Even in 2025, these limitations are still part of the list of realities that the International Federation of Robotics points out: battery life does not cover a full working day, and a human-like body does not automatically mean the ability to compete with industrial robots in speed, accuracy and repeatability (International Federation of Robotics, 2025c). This is why many earlier attempts turned into research projects, conference presentations or promotional videos, and the gap between mobility and repeatability in a real environment where small mistakes are repeated until they become costly.
The biggest change was not in the shape of the legs or the power of the motors alone, but in the mind that manages the body: control moved from explicit command logic to learning from data and experience, and then to contextual understanding. Deep computer vision models became more accurate in tracking objects and paths, but the leap came when language and vision began to merge with motor action in a single model, so that the robot can link what it sees to what it understands and what it does.The RT-2 paper provides an example of this trend: a vision-language-action model that integrates what it has learned from large-scale data with robotic trajectory data, and translates understanding into action, with better generalization to commands and tools that it has not seen in the same form within the robotic training data (Brohan et al., 2023).). At the industrial ecosystem level, major companies have been building platforms to accelerate the development of humanoid robots through simulation, synthetic data, and prototyping, such as NVIDIA's announcements at GTC 2025 about Isaac GR00T N1 as an open framework and prototype to accelerate the development of humanoid robots (NVIDIA, 2025).
It is not enough for a robot to walk: it needs to walk a thousand times in the same way without falling, pick up the same box under slight variations in position and weight, work long hours with a low error rate, and integrate with human safety procedures and warehouse systems. This is where the concept of industrial repeatability emerges as an economic contract: accuracy, stability, uptime, and ease of maintenance.When the business model itself begins to change via robot-as-a-service, the experience shifts from an expensive purchase to a measurable operation: hours worked, error rate, return on task, and gradual expansion. This is why the final question of the axis becomes more specific: when did the robot stop being a display and start being treated as a production item? The answer is not a single moment, but a moment when repeatability of performance becomes more important than beauty of movement, and measurement becomes more important than surprise.
Even in hardware, the story is no longer just about a more powerful motor, but a complete package: lighter and more durable materials, smaller components, touch and force/torque sensors that give the robot the ability to measure contact instead of guessing, compliance control that allows real-time correction for unexpected resistance, and more mature positioning and navigation systems.On the other hand, the standardization process is starting to catch up with the industry: ISO TC 299 has already started developing a global safety standard for autonomous unstable bipedal robots, which means that the industry is starting to treat the category as a product that will be subject to operational and liability requirements, rather than as a technical toy outside the rules of the market (International Federation of Robotics, 2025c).
Third: The pressure of economic reality - why do factories and warehouses need humanoid robots?
At the heart of the robotics resurgence is a demographic reality and a tense labor market, not science fiction. Many economies are aging, and dependency ratios are reaching unprecedented levels: the OECDEmployment Outlook 2025 states thatthe dependency ratio for older people in OECD countries will rise from 27% in 2023 to 48% by 2075, with a large transition from working age to retirement age within a few decades (OECD, 2025).In many industrialized economies, the gap between a high demand for repetitive, tedious work and a growing reluctance to replace it is widening. When "time" becomes the biggest cost in supply chains, the crisis turns into a daily operational pressure.
If we want to read the demand profile through the lens of robotics itself, the International Federation of Robotics figures show the center of gravity shifting towards large operating environments. Industrial robot installations in 2024 amounted to 542,076 units globally, with Asia/Australia dominating with 401,665 units, Europe with 92,985 units, and the Americas with 47,426 units (International Federation of Robotics, 2025a).Importantly, this investment is no longer confined to the closed factory; sales of professional service robots tell a different story: more than 199,000 professional service robots were sold in 2024, with transportation and logistics being the highest growth category (International Federation of Robotics, 2025b).
The classic industrial robot is static, great when the environment is designed for it, but costly to modify when tasks change. Here the humanoid form becomes an economic advantage rather than an aesthetic one: two arms, human-like stature, and the ability to work in environments designed for humans. The International Federation of Robotics summarizes this idea clearly: the humanoid form justifies itself when the goal is to work in an environment designed for humans and using human tools (International Federation of Robotics, 2025c).
In logistics, for example, Agility Robotics announced that its Digit robot went into commercial operation at a GXO facility near Atlanta, which it described as the first deployment of a humanoid robot in actual commercial operations, and then expanded with a multi-year RaaS agreement between GXO and Agility (Agility Robotics, 2024; GXO, 2024).In manufacturing, BMW announced in 2024 that it was testing the Figure 02 robot in a real production environment, while Figure AI later published operational results indicating 10-hour shifts, daily operation, and high handling volumes (BMW Group, 2024; Figure AI, 2025).With the introduction of "robot-as-a-service" models, whose fleets grew 31% in 2024, the investment barrier drops and the decision becomes closer to a monthly operating cost (International Federation of Robotics, 2025b). This begs the question: is robotics a technological solution or a forced response to a global labor crisis?
Fourth: Why 2025 is a pivotal year - when artificial intelligence meets the mechanical body
The fundamental difference at this moment is the robot's transition from a programmed machine to an intelligent agent that deals with uncertainty. Generative AI has changed the method of control: instead of writing rules for every situation, the robot understands instructions, relates them to what it sees and generates appropriate actions.The International Federation of Robotics describes this shift as new ways of acquiring capabilities by learning from demonstration and possibly self-discovering the task (International Federation of Robotics, 2025c). In industry, this is reflected in the building of a physical intelligence infrastructure that includes simulation, data, and underlying models (NVIDIA, 2025).
IFR figures indicate that the overall market for industrial robots is still above half a million installations per year, with installations expected to reach 575,000 units in 2025 and exceed 700,000 by 2028 (International Federation of Robotics, 2025a). With BMW announcing actual production tests and Figure AI publishing real operational indicators, the question shifts from technical feasibility to economic viability (BMW Group, 2024; Figure AI, 2025).
When a robot works where humans work, human skill is redefined. Reuters reported in March 2025 that Mercedes-Benz has invested in Apptronik and is testing the Apollo robot, with an estimate that the economic price will be in the tens of thousands of dollars per unit (Reuters, 2025).However, the IFR sets a realistic framework for expectations: humanoid robots will not compete with industrial robots in speed and accuracy, battery life does not cover a full working day, and safety standards are still being developed (International Federation of Robotics, 2025c). 2025 is therefore a watershed moment as the debate shifts from can to where, how, and at what cost.
V. Conclusion - Are we facing a robotic revolution or a labor revolution?
What the rise of humanoid robots reveals today is that the return is no longer a story of a human-like form, but of an economic system in search of new efficiencies.When the world records 542,076 installations of industrial robots in 2024, operational inventory reaches 4,663,698 robots, and sales of professional service robots exceed 199,000 units, robots have moved from the future to the infrastructure of the economy (International Federation of Robotics, 2025). The humanoid is an attempt to make this infrastructure work within a world designed for humans, while lowering the investment barrier.
If standards, safety, and social acceptance are catching up with technology, 2025 is not just the year of the robot, but the year of redefining the relationship between man, machine, and labor, based on numbers rather than fiction.
