- Humanoids, industrial and service robots on the upswing- humanoid robots are no longer a science fiction
The current technology landscape
The development of humanoid robots has made significant progress in recent years, driven primarily by advances in artificial intelligence. These machines can now perform complex movements that were previously considered impossible. Boston Dynamics has set new standards with its Atlas robot, which has switched from hydraulic to electric systems, resulting in more precise movements and a greater range of motion. The electric actuators enable Atlas to perform sophisticated actions and incorporate advanced machine learning algorithms that allow it to recognize and manipulate objects in real time without human intervention.
Tesla is working intensively on its Optimus robot, the second generation of which is slated for introduction in 2025. The company plans to produce several thousand units by the end of 2025 and potentially even build 10,000 Optimus robots. Tesla is leveraging its expertise in automotive and battery manufacturing to gain a competitive edge. The Optimus features a new robotic hand with 22 degrees of freedom and is expected to be positioned at a price of $20,000 in the medium term.
Figure AI has already achieved its first commercial sale of a humanoid robot with its Figure 02. This 1.68-meter-tall robot weighs 70 kilograms, can lift 20 kilograms, and operates for five hours on a single battery charge. Through its collaboration with OpenAI, Figure 02 can respond to natural language commands and is intended to become a thinking robot capable of making independent decisions.
Technical skills and application areas
Modern humanoid robots are characterized by their versatility, which distinguishes them from conventional industrial robots. They can operate in environments originally designed for humans without requiring extensive infrastructure modifications. This flexibility makes them particularly valuable for tasks in logistics, assembly, and maintenance.
Initial pilot projects are already demonstrating practical applications: Amazon is testing Agility Robotics' Digit in its warehouses for physically demanding tasks such as handling and transporting containers. Mercedes is testing Apptronik's Apollo, which is 1.73 meters tall, weighs 73 kilograms, and can lift 25 kilograms. BMW is using the Figure 02 in its car body shop, where it autonomously inserts sheet metal parts into machines.
Technological advances now enable these robots to automate up to 40 percent of tasks previously performed manually. Experts expect the capabilities of humanoid robots to improve by 35 to 40 percent between 2023 and 2025. In the first phase of development, they will primarily be able to handle logistical tasks such as sorting, transporting, and staging. From 2028 to 2030, they should also be able to manage highly varied tasks and complex processes in assembly.

Market development and economic prospects
The global market for humanoid robots is experiencing explosive growth. Various studies predict different development scenarios: the market was valued at US$1.68 billion in 2023 and is projected to reach US$23.73 billion by 2032, representing a compound annual growth rate (CAGR) of 34.2 percent. Other estimates project a market size of US$4.16 billion in 2023 and anticipate a CAGR of over 37 percent until 2032.
The most ambitious forecasts come from industry experts: Goldman Sachs estimates that the global market will reach a volume of US$38 billion by 2035. ARK Invest sees a maximum market potential of US$24 trillion. A Horváth study predicts that by 2030, 20 million humanoid robots will be in use worldwide, compared to the approximately 4.3 million industrial robots and cobots currently in operation.
Cost trends are positive: While manufacturing costs currently stand at around $250,000 per unit, a remarkable cost reduction is already underway. High-end humanoid models have seen their prices drop from $250,000 to $150,000 within a year – a decrease of 40 percent. Elon Musk predicts that costs will fall to around $20,000. Simpler models like the Unitree G1 are already available for $16,000.
Practical challenges and limitations
Despite impressive progress, humanoid robots face significant practical challenges. A key point of criticism concerns occupational safety: The European Machinery Directive and harmonized standards such as ISO 12100 place high demands on machine safety. The introduction of human-robot collaboration has already revealed significant challenges, which become even more complex with humanoid robots.
The complexity of human design is critically questioned by experts. Stefan Lampa, a robotics expert, argues: “The human body is not ideally configured for a car manufacturer. Why two arms, why two legs? This makes control much more complex.” Many of the abilities shown in marketing videos are remotely controlled and not autonomous, which raises the question of true autonomy.
Technical limitations persist in generalization and consistent planning over extended periods. Vision language models also struggle with generalization, posing a fundamental problem for autonomous decision-making. The scarcity of training data for robot models means that much of the training takes place in simulations, but transferring these simulations to the real world presents new challenges.

Social and ethical implications
The integration of humanoid robots into the workplace will have far-reaching societal consequences. Jobs could be significantly affected: An ING-Diba study predicts that, in the long term, 59 percent of jobs in Germany could be at risk, which would correspond to approximately 18 million out of 30.9 million employees. Office and administrative workers are particularly threatened, with an 86 percent probability of being replaced.
A recent Ifo survey shows that 27.1 percent of German companies expect artificial intelligence to make jobs redundant within the next five years. In the industrial sector, this figure is even higher, with 37.3 percent of companies anticipating job losses due to AI. If job cuts do occur, affected companies expect an average reduction in their workforce of 8 percent.
Ethical questions are gaining increasing importance. The moral and legal status of humanoid robots is among the top current topics in philosophy and legal theory. Philosophy professor Wolfgang Schröder argues that avoiding disrespectful treatment of robots could help preserve a fundamental normative ethical continuum in human behavior. Those who treat humanoid robots respectfully could also retain respect for other people.
Robot ethics distinguishes between different perspectives: robots as mere machines, robots with an intrinsic ethical dimension, robots as moral agents, or even as a new species. This discussion is fueled by the increasing autonomy of robots, which are achieving new levels of independence through artificial intelligence.
Regional development disparities
The development of humanoid robots is strongly influenced by regional factors. China is pursuing an aggressive strategy and aims to begin mass production by 2025. The Chinese Ministry of Industry and Information Technology has presented a plan according to which humanoid robots should reach mass production readiness by 2025. By 2027, China aims to develop humanoid robots that can think, learn, and innovate. At the World Robot Conference 2024 in Beijing, Chinese companies presented 27 new robots.
The US is experiencing a robotics renaissance, driven by software-oriented service robots and significant investment. Companies like Tesla, Boston Dynamics, and Figure AI are leading the technological advancements. The focus is on mobile robots, humanoids, and quadrupeds, with solutions that are more substantial than in other regions.
Europe is more reserved, focusing primarily on hardware and cost-efficient business management. One of the few exceptions is the German company Neura Robotics, which has developed the 4NE1, a humanoid robot that works autonomously and safely alongside humans in real-world environments. The Cologne-based company igus also offers a humanoid robot, the Iggy Rob, for under €50,000.

Ten billion humanoid robots by 2040: How our working world will fundamentally change
The future of humanoid robots will be shaped by several trends. Technological advances in the coming years will focus on AI and motion control, energy efficiency and battery technology, materials science and production techniques, as well as sensors and environmental perception. Elon Musk predicts that by 2040 there will be approximately ten billion humanoid robots on Earth.
Business models are expected to shift from direct sales to Robot-as-a-Service. Manufacturers will rent or lease their robots, with customers paying a fee per operating hour. This will allow manufacturers to earn significantly more per robot than through direct sales. Hourly labor costs could be 68 to 74 percent lower than those for human workers.
Initial applications will focus on industrial environments before humanoid robots find their way into private homes. Experts predict it will take another 5 to 8 years before robots can take over all major household tasks. Humanoid robots are better suited to the structured environments of factories than to private homes.
Societal adjustments will require new concepts for education, social systems, and work organization. Models such as machine taxes, hybrid income structures, and technological participation are moving into the focus of concrete policymaking. The education system is under pressure to prepare future generations for a technological world while simultaneously supporting the existing workforce through this transition.
Humanoid robots: Between future vision and industrial reality
Humanoid robots are at a turning point between visionary possibilities and practical realities. Technological advances in recent years, particularly in artificial intelligence, have transformed these machines from science fiction objects into serious industrial tools. While the first commercial applications are already a reality and market forecasts predict exponential growth, significant challenges remain in technical implementation, workplace safety, and social integration.
The development is largely shaped by an international race between China and the United States, while Europe risks losing connection. The economic potential is considerable, but they are associated with fundamental changes in the labor market and social structures. The coming years will be crucial for whether humanoid robots can redeem their promise as universal helpers or whether they end as an overpriced technical gimmick. However, it is certain that their integration into society will require well -thought -out political, ethical and economic framework conditions to maximize the opportunities and minimize the risks.
