Sweating robot? Rapid progress in Bionics Robotics with myofiber art muscles and skeletal cooling systems

Humanoid robots and their key role in the upcoming technological transformation

The rapid development of humanoid robotics stands on the threshold of a paradigm shift, which will not only bring technological but also profound social changes. We are at the beginning of an era in which humanoid robots are no longer just the subject of science fiction and research laboratories, but are increasingly entering our everyday life, our working world and our global technological landscape. The progress in this field is so dynamic that they not only transform industries, but also redesign labor markets and intensify international technological rivalry, especially between China and the Western nations.

The past ten years have experienced remarkable acceleration in humanoid robotics. Innovations in biomimetic design, the integration of artificial intelligence and strategic geopolitical considerations are the driving forces behind this development. What was once considered a futuristic vision, namely human -like robots that can take on complex tasks and interact with us, is now within reach. This transformation is made possible by breakthroughs in synthetic muscle skeleton systems, fluid-powered actuators and adaptive heat management systems. These technologies have developed humanoid robots from curious laboratory prototypes into a technology that is about to enter the market.

The progress is visible in different areas. Companies like Clone Robotics with their Protoclone V1 impressively demonstrate the possibilities of the latest biomimetic designs. At the same time, state -funded initiatives, as can be observed at UNTERREE Robotics, are driving the development on an even greater yardstick. At the same time, innovative cooling systems show how they are used in robots such as Kengoro and Andi that functional realism in robotics is becoming increasingly important. These cooling systems based on the principle of human sweating allow robots to work longer and more efficiently even under demanding conditions.

Bionics or biomimetics: Learning from nature for innovative technologies

A central term in the context of humanoid robotics is biomimetics, also called Bionik or Biomimikry. This discipline describes the approach of designing technical systems, materials or processes based on the model of nature. Nature has produced an immense variety of structures, functions and mechanisms over the course of millions of evolution, which are often surprisingly efficient and elegant. Biomimetics uses this evolutionary expertise as a source of inspiration for technological innovations.

The basic idea of ​​biomimetics is to analyze natural phenomena and to understand the underlying principles. These principles are then transferred to technical problems to develop new and improved solutions. The advantage of this approach is that it is based on proven and optimized solutions of nature, which have proven themselves in real environments over long periods of time.

There are countless examples of biomimetic developments that are used in various areas of technology and science. Some particularly relevant examples in the context of the robotics are:

Myofiber art muscles

These innovative actuators are inspired by the structure and functioning of human muscles. They enable robots smooth and natural movements and open up new opportunities for fine motor skills and dynamic movements.

Skeleton cooling systems

Robots like Kengoro use a cooling system that is modeled on human sweating. Due to the evaporation of liquid over a porous skeletal structure, heat is efficiently dissipated, which increases the operating time and performance of the robots.

Lighter shapes of aircraft

The aerodynamics of bird wings and whale fins have contributed significantly to the development of more efficient wing shapes for aircraft. Thanks to the imitation of natural designs, aircraft can save fuel and optimize their flight performance.

Velcro

A classic example of biomimetics is the Velcro fastener, which was developed based on the model of clets. The small checkmarks and loops of the burdock served as inspiration for a simple and effective closure system that is used today in numerous applications.

Biomimetics: How natural principles transformed technology

However, biomimetics are more than just imitating nature. It is an interdisciplinary approach that combines biology, engineering, material sciences and computer science. The aim is to understand the fundamental principles of nature and to creatively apply them to technical challenges. In robotics, biomimetics play a key role in developing humanoid robots that can move in natural environments and interact with people.

Clone Robotics: Anthropomorphic Robotics redefined

Lone Robotics is a company that is committed to developing state -of -the -art anthropomorphic robots and has set a remarkable milestone in this area with its protoclone V1. The Protoclone V1 is an impressive example of combining anatomical precision and engineering. This robot is the most comprehensive attempt to reproduce human biomechanics in a synthetic platform.

With a complex structure that includes 206 polymer-based bone analogue, 1,000 myofiber art muscles and a hydraulic vascular system, the protoclone V1 achieves remarkable mobility. It has 200 degrees of freedom, which even exceeds the human skeleton with its approximately 360 joints in terms of targeted articulation. This high number of degrees of freedom enables the robot a wide range of movements and poses that come close to that of a person.

A core of Clone Robotics technology are the myofiber art muscles. These actuators are inspired by McKibben pneumatic actors, but use an innovative construction with water-flowed stitch tubes. Under pressure, these tubes contract longitudinal and enable a contraction of up to 30 percent in less than 50 milliseconds. The power ratio of 3 grams to 1 kilogram shows the efficiency and performance of these art muscles. They enable fine -engine finger movements that are required for precise manipulation, as well as dynamic full -body poses, which were impressively demonstrated in a viral demonstration video in January 2025.

However, the Protoclone V1 is not only an impressive prototype, but also the forerunner for the "Clone Alpha" initiative, which provides for a limited market launch in 2025. The clone alpha is intended to integrate synthetic organ systems that imitate human metabolic processes. A grid-based “vascular network” distributes hydraulic fluid throughout the robot, while dual cameras and 320 pressure sensors create a proprioceptive feedback loop that resembles the biological nervous system. This feedback enables the robot to perceive its position and movement in the room and adapt its actions accordingly.

The polymer skeleton of the Clone Alpha contributes to a significant reduction in weight. It is 40 percent lighter than comparable aluminum frames, but still retains its stability under side loads of up to 200 Newton. This combination of lightness and stability is crucial for the agility and energy efficiency of the robot.

The first users of the Clone Alpha include luxury hotel chains and automobile manufacturers. These companies test the platform for various applications, including concierge services and precise assembly processes. In luxury hotels, for example, robots could help guests with check-in and check-out, provide information or transport luggage. In the automotive industry, they could be used in assembly processes, in which precision and repeatability are decisive.

Despite the impressive technical achievements of Clone Robotics and the Protoclone V1, the design of the robot also raises questions about public perception. The lack of facial features in combination with the hyper-realistic movements of the limbs can trigger the so-called "Uncanny Valley" phenomenon in some people. The Uncanny Valley describes a feeling of discomfort or rejection that arises when human -like robots or animations are similar, but at the same time have subtle differences that make them appear "scary" or "creepy".

Researchers, such as Dar Sleeper from Openaai, have observed that the design of the Protoclone V1 can potentially cause such reactions. In response to this, Clone Robotics adapted his marketing strategy. The focus is now less on the cosmetic humanity of the robots, but rather on its functional anthropomorphia. Clone robots are positioned as "powerful tools" and not as a human companion. This strategic realignment aims to increase the acceptance of the robots in public and to minimize possible negative reactions due to the Uncanny Valley.

Unitree Robotics and China's strategic robot offensive

UNITREE ROBOTICS is another company that plays a key role in the development of humanoid robotics, especially in the context of China's strategic focus on this technology field. The presence of UNITREEE CEO Wang Xingxing in the front row at an economic symposium with President Xi Jinping in February 2025 sends a clear signal: Humanoid robotics is viewed in China as a central pillar of the "new productive forces" and encouraged accordingly.

In his speech on the symposium, Wang Xingxing emphasized the remarkable progress in reinforcement learning architecture, which made it possible to significantly shorten the training cycles of the G1 robot for complex tasks. For demanding tasks such as folk dance choreography, the training cycles from 10,000 were reduced to just 800 iterations. This increase in efficiency in training of robots is crucial for the faster development and the broader use of humanoid robots in various areas of application.

The government program "Robotics+", which was launched in 2024, emphasizes China's commitment to robotics. This program provides $ 2.3 billion annually for the development of national actuator and sensor systems. This state funding directly benefits suppliers such as Zhejiang Changsheng, who had an impressive growth of 600 percent in the year. The massive state support shows that China considers robotics as a strategically important industry and invests in its development.

The G1 platform from UNTREE Robotics is a concrete example of China's pragmatic strategy for introducing humanoid robots. With 43 degrees of freedom, including 26 in each hand alone, the G1 achieves a considerable precision of 15 centimeters in object manipulation. It is noteworthy that Unitree relies on cost -efficient harmonious gears instead of proprietary actors. This approach indicates a strategy that is geared towards scalability and economy instead of maximum performance at all costs.

The “Yang Bot” spring festival performance was an impressive example of the skills of the G1 and the swarm robotic from Unitree. During this demonstration, 12 G1 robots demonstrated synchronized movements with an impressively low latency of only 0.2 seconds. This swarm coordination technology is of crucial importance for industrial swarm applications in which several robots have to solve complex tasks together.

In contrast to Clone Robotics, which focuses on a luxury positioning, Unitere is pursuing a strategy of scalable production with a comparatively low basic price of $ 45,000 for the G1. This pricing aims to make the robot accessible to a wider audience and to promote use in various industries. Partnerships with companies such as Alibaba Cloud integrate advanced language models such as Tongyi Qianwen-LLMS to enable natural language programming of tasks. This simplification of the programming lowers the entry hurdle for small and medium -sized companies (SMEs) and facilitates the integration of robots into existing workflows.

The Unitreree production facility in Shenzhen is currently producing 200 G1 units per month. The company pursues ambitious goals and plans to achieve a market share of 30 percent in the Asian market for logistics automation by 2027. This strategic focus on the logistics sector, which has enormous growth potential, underlines China's ambitions to play a leading role in the global robotic industry.

Biomimetic heat management: sweating robots for longer operating time

 

One of the biggest challenges in robotics, especially for humanoid robots with complex movements and high power consumption, is heat management. The electronic components and actuators installed in robots generate heat in operation, which must be removed to avoid overheating and associated loss of performance or damage. Biomimetic approaches offer innovative solutions that are inspired by nature.

A remarkable example of biomimetic heat management is the skeletal cooling system of the robot Kengoro, which was developed at the University of Tokyo. Kengoro has a thermore-regulating skeleton made of 3D printed porous aluminum. Due to the structure, microcapillars with a diameter of only 50 micrometers. Deionized water is directed through these capillaries, which evaporates with a rate of 30 milliliters per hour. This evaporation process takes heat and enables a cooling capacity of 488 watts, compared to 359 watts with conventional air cooling.

This innovative cooling system enables Kengoro to continuously work even with strenuous exercises such as pushups over a longer period of time, without the engines to overheat the engines. In tests, Kengoro was able to complete 11-minute push-up operations without the engine output. However, the system also has a disadvantage: it leads to a weight gain of 12 percent compared to conventional cooling systems.

The Arizona State University's Andi project has further developed and improved the concept of the sweating robot. Andi has 35 independent welding zones and carbon fiber “pores”, which can adaptively adapt their evaporation rates based on the data of 200 internal temperature sensors. In tests in Phoenix, Arizona, at an ambient temperature of 47 degrees Celsius, the system was able to maintain the temperature of critical components below 85 degrees Celsius. At the same time, Andi used 23 percent less coolant than closed fluid cooling systems. This adaptive welding model shows that biomimetic cooling systems can not only be efficient, but also resource -saving.

Despite their efficiency, sweating cooling systems also have challenges, especially with regard to maintenance and long -term stability. For example, Kengoro needs weekly descaling rinsing to free the microcapillars of deposits that could affect cooling performance. At Andi it was found that the epoxy resin skin tends to degradation symptoms after 200 heating cycles. These maintenance and durability problems are important aspects that must be taken into account in the further development and industrial use of sweating robots.

Passive cooling methods are also researched as an alternative to liquid -based cooling systems. Clone Alpha, for example, relies on phase change material layers (PCM) in the muscles. PCM are materials that change their kit at a certain temperature and absorb or release heat. This passive cooling does not require any liquid systems, but has a 18 percent lower heat absorption capacity compared to active, fluid -based systems. The choice of the appropriate cooling system ultimately depends on the specific requirements of the robot application, including the required cooling performance, weight, maintenance requirements and the operating environment.

Global market dynamics and ethical considerations in humanoid robotics

Humanoid robotics is not only an exciting technology field, but also a high -growth market with considerable global effects. In 2024, the risk capital volume in the humanoid robotics sector reached impressive $ 17.4 billion. The Asian-Pacific area made up the largest share of 61 percent, which underlines the importance of Asia, especially China.

In addition to the primary robotics manufacturers, secondary markets also benefit from this growth. Suppliers of special components and technologies record disproportionate growth. An example of this is the company Harmonic Drive SE, the stock of which rose by 89 percent after it was able to secure the UNTERRE reduction gear. This development shows that the value chain of humanoid robotics is diverse and offers numerous business opportunities.

With the increasing use of humanoid robots in various areas, regulatory and ethical questions also come to the fore. The European Union works, for example, on a draft guideline on artificial liability law (probably in 2026). This guideline could stipulate that humanoid robots have to meet certain safety standards, such as limited skin pressure forces of less than 80 Newton per square centimeter and emergency shutdowns. Such regulatory measures aim to ensure security in dealing with humanoid robots, but could also increase the costs per unit by an estimated $ 12,000. It is important to find a balanced approach that promotes both the safety of people and the innovative strength of the robotics industry.

In addition to regulatory questions, ethical dilemma also plays an increasingly important role. The "synthetic people" rhetoric used by companies like Clone Robotics raises profound philosophical questions about identity, autonomy and the relationship between man and machine. A study by the one from 2024 showed that 68 percent of the participants attributed intentional will to protoclone V1, although they were informed about its programming. These results indicate that the perception of humanoid robots is complex by humans and is influenced by various factors, including the design of the robots and the way they are presented in public.

The increasing humanity of humanoid robots also raises questions about its role in society. Do you become a job competitor or valuable helpers in various areas of life? How does your presence influence our social interactions and our self -image as humans? These questions require a broad social debate in which experts from various disciplines, politicians, companies and the public must be involved. This is the only way to ensure a responsible and ethically justifiable handling of humanoid robots, which optimally uses the opportunities of this technology and at the same time minimizes possible risks.

The future of humanoid robotics - a balancing act between technology and society

The humanoid robotics is located in a dynamic and exciting stage of development. Rapid technological progress, especially in the areas of biomimetics, artificial intelligence and material sciences, enable the development of increasingly efficient and human -like robots. Companies such as Clone Robotics and UNTREE Robotics drive this development significantly with their innovative approaches and products.

The future of humanoid robots is not only decided technically, but also socially

At the same time, we face the challenge of reconciling the technological possibilities with social needs and ethical considerations. Regulatory framework conditions must be created that promote security and innovation equally. An open and broad social debate is necessary to discuss the ethical and social implications of humanoid robotics and to design a responsible dealings with this technology.

The future of humanoid robotics is not only decided by technological innovations, but also largely through social acceptance, ethical guidelines and a responsible handling of this transformative technology. It is up to us to set the course in such a way that humanoid robots become an enrichment for humanity and not to a source of conflicts or inequality. The potential is enormous, but it requires a clear compass and a common effort to use this potential for the benefit of everyone.
