ALLEX (short for ALL-EXperience) is a general-purpose humanoid robot developed by WIRobotics, a South Korean robotics company founded by former Samsung engineers. Unveiled on August 18, 2025, at the Robot Innovation Hub on the campus of the Korea University of Technology and Education (KOREATECH) in Cheonan, South Korea, ALLEX is designed around the principle of safe, compliant physical interaction with humans. The robot features proprietary ultra-low-friction backdrivable actuators, a 15-degree-of-freedom (DOF) compliant hand capable of 40 N fingertip force, and whole-body force sensing that operates without conventional external force or torque sensors.
WIRobotics describes ALLEX as "the first robot that truly experiences and responds to the real world," referencing its ability to detect and react to force, contact, and impact across its arms, fingers, and waist. The robot has attracted significant attention from global technology leaders including NVIDIA, Meta, and Amazon, and in March 2026 WIRobotics was selected for the Physical AI Fellowship powered by AWS, NVIDIA, and MassRobotics.
WIRobotics ("We Innovate Robotics") was founded in June 2021 by four former engineers from Samsung Electronics' Robotics Development Team. The founding team consists of Co-CEO Younbaek Lee, Co-CEO and CTO Yong-Jae Kim (a professor at KOREATECH who studied at the Korea Advanced Institute of Science and Technology, or KAIST), CFO Changhyun Noh, and COO Byungjun Choi. The company operates under the vision "Technology for People, Enhancing Quality of Life," with a stated goal of bringing robotic assistance out of laboratories and industrial facilities and into everyday life.
Before entering the humanoid robotics space, WIRobotics established itself through wearable robotics. The company's first product was WIBS (We Innovate Back Support), an unpowered back-support exoskeleton designed for industrial workers. This was followed by WIM (We Innovate Mobility), an ultra-lightweight walking-assist wearable robot weighing just 1.6 kilograms. WIM provides hip-joint actuation to both legs from a single motor worn at the waist and offers four operational modes: Assist Mode (reducing energy consumption by 20% during level-ground walking), Resist Mode (adding resistance for lower-body strengthening), Hiking Mode (stabilizing uphill and downhill movement), and Slow Gait Mode (enhancing control for rehabilitation). A four-week usability test with seniors demonstrated a 78% improvement in physical functions, including enhanced walking speed, endurance, and lower-body strength.
In 2025, WIRobotics expanded its wearable lineup with WIM Kids, a walking-assist device for children ages 4 to 15. Featuring a growth-adaptive modular leg frame and weighing only 990 grams, WIM Kids won the CES 2026 Innovation Award in the Digital Health category. This marked WIRobotics' third consecutive CES Innovation Award, following wins in the Robotics category in 2024 and 2025.
WIRobotics has raised capital through multiple rounds to support its expansion from wearable to humanoid robotics.
| Round | Date | Amount | Lead Investor | Other Investors |
|---|---|---|---|---|
| Pre-Series A | April 2023 | KRW 4 billion (~$3M USD) | Not disclosed | Not disclosed |
| Series A | March 2024 | KRW 13 billion (~$10M USD) | InterVest | GU Equity Partners, JB Investment, Company K Partners, Hana Ventures, FuturePlay |
The Pre-Series A funds were used primarily for the development, operations, and marketing of the WIM wearable robot, as well as team expansion. The Series A round was directed toward accelerating the commercialization of wearable robots and initiating the development of ALLEX.
ALLEX was designed with a fundamentally different approach from many competing humanoid platforms. Rather than relying primarily on vision and position control, the robot prioritizes force-based interaction. Its proprietary actuators provide ultra-low friction and high backdrivability, meaning the robot's joints can be moved easily by external forces. This makes the robot inherently safe for human contact, as the low mechanical resistance means the robot yields to unexpected forces rather than resisting them.
The name ALLEX reflects this philosophy: "ALL-EXperience" signifies the robot's capacity to perceive and respond to physical stimuli across its entire body. WIRobotics positions ALLEX not merely as a robot that replicates human movement, but as one that can sense and adapt to the physical environment in real time.
As of its August 2025 unveiling, ALLEX has been presented as an upper-body system (torso, arms, and hands), with plans for full-body configurations in subsequent development phases. The total system has 48 degrees of freedom.
The core of ALLEX's mechanical design is its ultra-low-friction, high-load actuator. According to WIRobotics, these actuators exhibit more than 10 times lower friction and rotational inertia than conventional collaborative robot arms. This low friction enables several key capabilities:
The shoulder-to-hand assembly weighs approximately 5 kilograms, yet the system can handle payloads of 3 kilograms or more per hand across the full workspace. WIRobotics claims this gives ALLEX performance equivalent to collaborative robots weighing over 20 kilograms.
The ALLEX hand is one of the robot's most distinctive subsystems and a primary differentiator in the competitive landscape. Each hand is human-sized, features five fingers, and provides 15 degrees of freedom.
| Specification | Value |
|---|---|
| Degrees of freedom (per hand) | 15 |
| Fingers per hand | 5 |
| Hand weight | ~700 g |
| Fingertip force | 40 N |
| Hook-grip strength | >30 kg |
| Fingertip repeatability | ≤0.3 mm |
| Force detection threshold | ~100 gf (without tactile sensors) |
The 40 N fingertip force is notable because it places ALLEX among the strongest high-DOF, human-scale robotic hands documented. For comparison, the human hand can typically exert between 7 N and 50 N of fingertip pinch force depending on the finger, making ALLEX's force output comparable to a moderately strong human grip. The hook-grip strength exceeding 30 kilograms further demonstrates the hand's capacity for heavy holding tasks.
Despite this grip strength, the hand maintains fine force sensitivity. WIRobotics reports that ALLEX's fingers can detect reaction forces as small as 100 gram-force (approximately 1 N) without any dedicated tactile sensors. This sensitivity is achieved through the mechanical compliance of the actuators themselves, which allows the control system to infer contact forces from motor current and position data. The fingertip repeatability of 0.3 mm or less enables precise manipulation of small objects.
This combination of high force output and fine sensitivity means ALLEX can perform both power grasps (carrying heavy bags, turning stiff door handles) and precision tasks (handling eggs, picking up thin objects) with the same end-effector.
ALLEX uses a motor-control algorithm that integrates position control, force control, and stiffness control. This allows the robot to switch smoothly between rigid positioning (for accurate placement tasks) and compliant behavior (for safe human interaction). The system implements whole-body force sensing across the arms, fingers, and waist, enabling coordinated responses to physical contact anywhere on the upper body.
The control architecture was also designed to minimize the sim-to-real gap for machine learning applications. By providing consistent, low-friction mechanical behavior, the real robot more closely matches the idealized conditions of physics simulators, which makes learned policies transfer more reliably from simulation to the physical platform.
ALLEX is equipped with onboard processors optimized for executing AI motion and force control algorithms in real time. The system supports large language model (LLM) integration and is compatible with cloud robotics architectures. The software stack is proprietary (closed source) but supports integration with external AI platforms.
For intelligence development, WIRobotics has partnered with RLWRLD, a South Korean physical AI startup that develops robot foundation models for industrial environments. RLWRLD, which has raised $42 million in total seed funding, uses ALLEX as a testbed for its AI models. This partnership pairs WIRobotics' hardware expertise with RLWRLD's capabilities in learned manipulation and physical reasoning.
The dexterous hand market for humanoid robots has become increasingly competitive. The table below compares ALLEX's hand specifications with several prominent systems.
| Robot | Hand DOF | Fingertip Force | Hand Weight | Actuation Type |
|---|---|---|---|---|
| ALLEX (WIRobotics) | 15 | 40 N | ~700 g | Backdrivable electric |
| Optimus (Tesla) Gen 3 | 22 | Not disclosed | Not disclosed | Tendon-driven electric |
| Figure 02 (Figure AI) | 16 | Not disclosed | Not disclosed | Electric |
| Phoenix (Sanctuary AI) | 21 | Not disclosed | Not disclosed | Hydraulic |
| GR-2 (Fourier Intelligence) | 12 | Not disclosed | Not disclosed | Electric |
While Tesla's Optimus Gen 3 and Sanctuary AI's Phoenix offer more degrees of freedom per hand, ALLEX's publicly documented 40 N fingertip force and 30+ kg hook-grip strength represent some of the highest force figures disclosed for a high-DOF, human-scale robotic hand. Many competing platforms have not published detailed force specifications, making direct force comparisons difficult. ALLEX's 700-gram hand weight is also notably light for the level of capability it provides.
WIRobotics has identified several primary application domains for ALLEX:
WIRobotics plans to develop ALLEX as a modular platform, offering arms, hands, body modules, and leader (teleoperation) systems either individually or in combination. A wheeled mobile base configuration has also been announced for deployment scenarios where bipedal locomotion is not required. The company has stated its goal of delivering a general-purpose humanoid platform that "anyone can use in everyday life" by 2030.
WIRobotics has built an extensive network of research and industry partnerships to accelerate ALLEX's development:
| Partner | Type | Focus Area |
|---|---|---|
| RLWRLD | Industry (physical AI startup) | Robot foundation models, AI intelligence |
| MIT | Academic | Robotics research |
| University of Illinois Urbana-Champaign (UIUC) | Academic | Robotics research |
| University of Massachusetts (UMass) | Academic | Robotics research |
| KIST (Korea Institute of Science and Technology) | Research institute | Robotics R&D |
| Maxon | Industry (actuator supplier) | Actuators and drivetrains |
| AWS / NVIDIA / MassRobotics | Fellowship program | Physical AI development |
In March 2026, WIRobotics was selected for the second cohort of the Physical AI Fellowship, a virtual program powered by AWS Startups and NVIDIA Inception. The 2026 cohort includes nine robotics startups spanning agriculture, construction, renewable energy, industrial automation, retail, logistics, and humanoid robotics. WIRobotics is the only humanoid robotics company in the cohort.
Through the fellowship, WIRobotics receives $200,000 in AWS credits, embedded support from the AWS Generative AI Innovation Center, access to NVIDIA's physical AI stack (including the NVIDIA Isaac frameworks and NVIDIA Cosmos world foundation models), free NVIDIA training courses, and access to MassRobotics' testbed facilities. The fellowship culminates in high-visibility showcases at AWS re:Invent 2026 and other industry events.
WIRobotics exhibited at CES 2026 in Las Vegas (Venetian Expo, Hall A-D, Booth #54635), showcasing both the ALLEX humanoid and its WIM S wearable robot. The ALLEX demonstration featured live movement and interaction sequences, including a natural handshake that showcased the robot's real-time force sensing and responsive grip adjustment. During the demonstration, ALLEX shook hands with visitors without crushing or applying excessive force, illustrating its inherent compliance and safety.
Following the demonstrations, representatives from major technology companies including NVIDIA, Meta, and Amazon expressed purchase interest. According to WIRobotics, several of these discussions progressed beyond preliminary contact to specific directions for technical collaboration and joint technology development. Media outlets and buyers from North America, the Middle East, and South America actively engaged with the company regarding its robotics portfolio and global expansion plans.
Co-CEO Younbaek Lee stated that CES 2026 represented "a pivotal transition from presenting technology to executing real collaboration," signaling the company's shift from demonstration phase to active commercialization.
ALLEX exists within a rapidly growing South Korean humanoid robotics sector. In April 2025, the South Korean government launched the K-Humanoid Alliance, a national initiative to position the country as a global leader in humanoid robots by 2030. The government has pledged approximately $770 million in investment, with $150 million allocated for 2025 alone.
The alliance includes major companies such as Rainbow Robotics (whose RB-Y1 robot benefits from Samsung's investment as the largest shareholder), Aeirobot, Holiday Robotics, BlueRobin, Robros, Angel Robotics, and Neuromeka. Over 20 universities and research institutions participate, including KAIST, Seoul National University, Yonsei University, and Korea University. The alliance's technical targets include producing humanoid robots weighing under 60 kilograms, with more than 50 joints, payload capacities exceeding 20 kilograms, and movement speeds over 2.5 meters per second.
WIRobotics occupies a distinctive niche within this ecosystem. While larger players like Rainbow Robotics (backed by Samsung) focus on full-body bipedal humanoids, WIRobotics differentiates through its emphasis on manipulation, compliance, and safe physical interaction. The company's background in wearable robotics gives it particular expertise in designing lightweight, energy-efficient systems that interact closely with the human body.
South Korea's humanoid robotics push is driven in part by demographic pressures. The country has the world's lowest birth rate and a rapidly aging population, creating urgent demand for robotic solutions in eldercare, service industries, and manufacturing. Companies like WIRobotics, with their dual focus on wearable assistive devices and humanoid platforms, are positioned to address both near-term (wearable rehabilitation) and long-term (autonomous humanoid assistance) segments of this market.
WIRobotics has outlined a phased approach to bringing ALLEX to market:
| Phase | Timeline | Milestone |
|---|---|---|
| Upper body unveiling | August 2025 | Demonstration of torso, arms, and hands at KOREATECH |
| CES 2026 showcase | January 2026 | Live demonstrations; industry partnership discussions |
| Research platform | Late 2026 | Commercial availability of research-focused platform |
| Wheeled mobile base | 2026 (planned) | Expanded configuration with mobile base |
| Modular platform sales | 2027+ (projected) | Individual arms, hands, body, and leader systems |
| General-purpose deployment | 2030 (target) | Everyday-use humanoid platform |
The research platform expected in late 2026 will allow academic and industrial partners to develop applications on ALLEX hardware. The wheeled mobile base configuration addresses use cases in logistics and service environments where bipedal locomotion is unnecessary. The longer-term modular platform strategy allows customers to purchase only the components they need, lowering the barrier to adoption.
