Alice is a series of humanoid robots developed by AeiROBOT Co., Ltd., a South Korean robotics startup headquartered in Ansan, Gyeonggi-do. The Alice platform has evolved through multiple generations, beginning as an autonomous soccer robot for the RoboCup Humanoid League and progressing into a commercially oriented humanoid designed for manufacturing, logistics, and service applications. The current flagship model, Alice 4, is a bipedal humanoid standing 160 cm tall with 41 degrees of freedom and proprietary gearless linear actuators that enable precise force control and quiet operation. A companion model, Alice M1, is a wheeled semi-humanoid mobile manipulator optimized for factory environments.
AeiROBOT operates under the motto "A Robot for All," reflecting its goal of making capable humanoid hardware accessible for education, research, and practical automation at price points significantly lower than many Western competitors. At CES 2026, the Alice robots were featured in NVIDIA CEO Jensen Huang's keynote address as an example of real-world physical AI applications.[1][2]
AeiROBOT was founded in January 2017 (with formal incorporation in 2018) as a spin-off from the HERoEHS (Humanoid Robot for Emotional and Human Interaction Services) laboratory at Hanyang University ERICA campus. The lab is led by Professor Jeakweon Han of the Department of Robotics Engineering, who serves as AeiROBOT's Chief Technology Officer.[3][4] Professor Han is an Associate Professor specializing in humanoid robotics, with research spanning bipedal locomotion, human-robot interaction, and autonomous robot control systems. His academic work has been cited over 500 times in the scholarly literature.[5]
The company is headquartered at the Startup Incubation Center at 55 Hanyang University Road, Sangrok-gu, Ansan-si, Gyeonggi-do, South Korea. As of 2026, the company employs between 11 and 50 people.[6]
On July 11, 2025, AeiROBOT completed a Series A funding round of approximately $7.2 million (KRW 10 billion). The round was led by new investors including BonAngels Venture Partners, Korea Development Bank (KDB), NH Venture Investment, and Innopolis Partners, with existing investors Hana Ventures and SGC Partners also participating.[7]
AeiROBOT has been selected for the NVIDIA Inception Program, gaining access to technical guidance, hardware resources, and global partnership opportunities. The company is an early adopter of NVIDIA's Isaac GR00T platform, an AI system optimized for full-body humanoid control that integrates walking control, environmental perception, and autonomous decision-making.[8]
In 2025, AeiROBOT partnered with Advantech, a global leader in edge AI and embedded computing, to integrate Advantech's AFE-R360 computing platform into the Alice M1. The AFE-R360 is a compact 3.5-inch single board computer powered by an Intel Core Ultra series processor, providing real-time sensor fusion and AI-driven decision-making capabilities.[9]
Before its commercial pivot, the Alice robot platform earned international recognition through the RoboCup Humanoid League, one of the most prestigious competitions in autonomous robotics. The HERoEHS team from Hanyang University competed in the AdultSize category using successive versions of the Alice robot (Alice 1 through Alice 3.5), building a strong track record over multiple years:[10]
| Year | Location | Placement | Technical Challenge |
|---|---|---|---|
| 2018 | Montreal, Canada | Quarterfinals (8th) | N/A |
| 2019 | Sydney, Australia | 5th place | N/A |
| 2021 | Virtual | 3rd place | N/A |
| 2022 | Bangkok, Thailand | 2nd place (Runner-up) | 2nd place (17 pts) |
| 2023 | Bordeaux, France | 2nd place (Runner-up) | 1st place (37 pts) |
| 2024 | Eindhoven, Netherlands | 3rd place | 1st place (25 pts) |
The team achieved consecutive runner-up finishes in 2022 and 2023, losing both finals to the University of Bonn's NimbRo AdultSize team, one of the dominant forces in the league. Their consistent first-place finishes in the Technical Challenge category demonstrated strong capabilities in areas such as vision, ball handling, and high-level behavior. These competition results validated the control technology that enables Alice robots to make decisions and walk autonomously in complex environments, and the technological assets from the competition platform now carry directly into the commercial Alice 4.[1]
AeiROBOT is a founding member of the K-Humanoid Alliance, a national consortium launched by South Korea's Ministry of Trade, Industry and Energy on April 10, 2025. The alliance includes over 40 domestic robotics manufacturers, component suppliers, and research institutions, with the goal of making South Korea a global superpower in humanoid robotics by 2030. The South Korean government has committed to investing over KRW 1 trillion (approximately $770 million) in the initiative by 2030.[11]
Professor Jeakweon Han leads the robot manufacturing group within the alliance. The alliance's first major objective is to develop a "robot AI foundation model" by 2028, creating a shared AI platform that can be used by various robot manufacturers. The second mission is to develop humanoid hardware that meets the highest global specifications.[11]
AeiROBOT is notable within the alliance as the first humanoid robot company in South Korea to receive Regulatory Sandbox approval for conducting field demonstrations of humanoid robots in manufacturing factories.[2]
Alice 4 is the fourth-generation bipedal humanoid from AeiROBOT, designed for safe collaboration in service and industrial settings. It represents the culmination of the company's RoboCup experience translated into a commercially viable platform. Standing 160 cm tall and weighing 45 kg, Alice 4 features 41 degrees of freedom and in-house-developed gearless linear actuators mounted on all joints.[6][12]
The robot is capable of rough-terrain walking, stair navigation, and precise force control. It can operate with standard human tools without requiring facility modifications, making it suitable for deployment in existing workspaces alongside human workers. Alice 4 supports multi-modal perception through depth cameras and inertial measurement units, and enables natural-language dialogue and context-aware gestures driven by AI processing.[12]

The most distinctive technical feature of Alice 4 is AeiROBOT's proprietary gearless linear actuator system. Unlike conventional humanoid robots that rely on rotation-motor and reducer-based systems (such as harmonic drives or cycloidal gearboxes), AeiROBOT's actuators use a direct-drive linear mechanism that eliminates the reducer entirely.[1][12]
This design choice offers several advantages over traditional approaches:
| Characteristic | AeiROBOT Gearless Linear Actuator | Conventional Rotary + Reducer |
|---|---|---|
| Force control precision | High (direct force sensing) | Lower (gear backlash, friction) |
| Noise level | Low (no gear meshing) | Higher (gear noise) |
| Energy efficiency | Higher (no gear losses) | Lower (friction losses in reducer) |
| Back-drivability | Excellent (low friction) | Limited (high reduction ratio) |
| Current sensitivity | High | Moderate |
| Durability | Improved (fewer wear parts) | Gear wear over time |
| Manufacturing cost | Lower (fewer precision components) | Higher (precision gear sets) |
| Physical interaction safety | Natural, compliant | Stiffer, less compliant |
By mounting multiple parallel linear actuators on each joint, Alice 4 simultaneously achieves the force output needed for stable bipedal walking on uneven terrain and the fine control required for delicate manipulation tasks. The actuators are highly sensitive to current changes, making them inherently back-drivable, which is a critical safety feature for robots that operate alongside humans. If a person pushes or bumps into the robot, the joints can yield rather than resisting rigidly.[1]
AeiROBOT manufactures most of these components in-house, maintaining control over quality and costs. The company describes the linear actuator as the "muscle" of its robots and considers it a key factor that simultaneously improves performance and reduces manufacturing costs compared to competitors relying on off-the-shelf harmonic drives or similar components.[1]
Alice 4 runs on a dual-compute architecture combining an NVIDIA Jetson Orin NX module for real-time AI inference with a GENE-RAP6 processor for additional computing tasks. Together, these handle live vision data and AI workflows for object detection, autonomous task execution, and environmental understanding.[12]
The software stack includes several key capabilities:
Real-time Field-Oriented Control (FOC): A control algorithm optimized for the linear actuators that enables smooth, responsive joint movements with minimal latency. This is essential for maintaining balance during dynamic walking and for precise force control during manipulation tasks.
Vision and AI pipelines: The depth cameras feed into object detection and scene understanding models running on the Jetson Orin NX. These pipelines enable Alice 4 to recognize objects, estimate their positions in 3D space, and plan grasps accordingly.
Natural language processing: Integrated NLP capabilities allow Alice 4 to understand voice commands and respond with contextually appropriate speech and gestures. This feature is powered by cloud-based large language model integration over Wi-Fi.
VR teleoperation and imitation learning: Alice 4 supports VR-based teleoperation, where a human operator wears a VR headset and controls the robot's movements in real time. The movements captured during teleoperation can be recorded and used as training data for imitation learning algorithms, allowing the robot to gradually acquire new skills without explicit programming.[12]
The integration of NVIDIA Isaac GR00T, a full-body control AI platform for humanoid robots, is a significant software milestone. Isaac GR00T provides a unified framework for walking control, environmental perception, and autonomous decision-making, enabling Alice 4 to understand natural language commands and translate them into coordinated whole-body actions in industrial settings.[8]
Alice M1 is a semi-humanoid mobile manipulator that pairs a humanoid upper body with a wheeled mobile base. Designed as a complement to Alice 4, the M1 prioritizes stability and operational endurance over bipedal locomotion, making it suitable for immediate deployment in manufacturing environments where the primary requirements are mobility, reach, and manipulation rather than walking.[1][9]
| Category | Specification | Value |
|---|---|---|
| Physical | Height | 130 to 180 cm (adjustable) |
| Physical | Weight | 97 kg |
| Mobility | Total degrees of freedom | 31 |
| Mobility | Arm DOF | 7 per arm |
| Mobility | Base type | Wheeled (omnidirectional) |
| Mobility | Waist | Horizontally and vertically movable |
| Computing | Platform | Advantech AFE-R360 (Intel Core Ultra) |
| Sensing | Sensors | Stereo cameras, IMU, 3D LiDAR, laser |
The M1's adjustable height (1.3 to 1.8 meters) is achieved through a movable waist structure that allows the robot to work at varying heights in confined factory aisles. The 7-DOF robotic arms provide dexterous manipulation capabilities for picking, placing, and assembly tasks.[9]
At CES 2026 in Las Vegas (January 6 to 9, 2026), AeiROBOT exhibited at the HUMANOID M.AX Alliance Pavilion alongside nine other South Korean robotics companies as part of the K-Humanoid Alliance's first collective international showcase. The companies included Tomorrow Robotics, Blue Robin, ROBROS, Robotis, Neuromeka, Tesollo, Aidin Robotics, Faraday Dynamics, and SBB Tech.[2]
AeiROBOT demonstrated a coordinated workflow between Alice 4 and Alice M1, showcasing their ability to collaborate on manufacturing and logistics tasks. In the demonstration, Alice 4 recognized a tumbler on a table, automatically adjusted its grip strength and wrist angle to grasp it, and transferred it into a box. Alice M1 then picked up the organized items, placed them onto a conveyor belt, and sent them to the next process station. This sequence illustrated how bipedal and wheeled humanoids could work together in a real production line without requiring any modifications to the existing facility.[2]
NVIDIA CEO Jensen Huang selected AeiROBOT's demonstration as a use case during his CES 2026 keynote address, in which he declared that "the ChatGPT moment for physical AI is here." The mention highlighted AeiROBOT's integration of the Isaac GR00T platform and positioned the company as a notable player in the emerging physical AI ecosystem.[2][8]
In addition to the Alice humanoid series, AeiROBOT develops two other robot platforms:
AIMY is an autonomous welcome and service robot standing 150 cm tall and weighing 44 kg, with 23 degrees of freedom. It is equipped with an AMD Ryzen 5 7600 CPU and NVIDIA RTX 4060 Ti GPU, providing substantial processing power for AI-driven interactions. AIMY features depth, infrared, and tracking cameras alongside laser sensors for spatial navigation and obstacle detection. An 8-inch head display and 13.3-inch torso touchscreen enable visual content delivery. AIMY is designed for hospitality, retail, and customer service environments, where it provides interactive wayfinding, content promotion, and LLM-powered conversational engagement.[13]
EDIE is a companion robot designed for emotional interaction and social support. Detailed specifications have not been publicly released as of early 2026.[6]
AeiROBOT focuses on industries facing severe labor shortages, positioning its humanoid robots as practical solutions rather than research curiosities. The company's primary target sectors include:
Manufacturing: Factory floor tasks such as parts handling, assembly, quality inspection, and conveyor operations. AeiROBOT has conducted field demonstrations at manufacturing sites including HL Mando (automotive components) and Amorepacific (cosmetics), validating the robots' ability to operate alongside human workers in real production environments.[4]
Shipbuilding: Demonstrations at HD Hyundai Heavy Industries and Samsung Heavy Industries shipyards, where humanoid robots can navigate confined and hazardous spaces typical of ship construction environments.[4]
Construction: Tasks in construction sites where labor shortages are particularly acute and where the robot's ability to navigate unstructured environments with stairs and obstacles is valuable.
Service and hospitality: Customer-facing roles in hotels, retail stores, and public venues, leveraging Alice 4's natural language dialogue and gesture capabilities.
Research and education: University laboratories and research institutions that need an accessible humanoid platform for studying bipedal locomotion, reinforcement learning, computer vision, and human-robot interaction.
Alice 4 enters a rapidly growing global market for humanoid robots. The following table compares Alice 4 with other humanoid platforms in a similar size and price range.

Alice 4's key differentiator is its proprietary gearless linear actuator system, which sets it apart from the vast majority of humanoid robots that use conventional rotary motors with gear reducers. Its 41 degrees of freedom is among the highest in its class, and its RoboCup competition pedigree provides a proven track record in autonomous locomotion. However, the robot faces stiff competition from Chinese manufacturers, who often benefit from lower production costs and larger engineering teams.
AeiROBOT has outlined an ambitious roadmap for the Alice platform and the company's broader business strategy:
Proof-of-concept validation (by 2028): The company plans to complete proof-of-concept demonstrations across manufacturing, shipbuilding, and construction, transitioning from pilot testing to revenue-generating deployments at real work sites.[1]
European expansion: AeiROBOT plans to supply Alice 4 and Alice M1 to European countries including Germany, the United Kingdom, France, and Italy, targeting nations that face labor shortages and structural industrial changes. The company is proactively pursuing global certification processes in compliance with the EU AI Act and the new Machinery Regulation.[1]
Robot as a Service (RaaS): In the longer term, AeiROBOT envisions transitioning beyond hardware sales to a Robot as a Service model that bundles the AI platform (the robot's "brain") with ongoing maintenance and support services. This subscription-based approach would lower the upfront cost barrier for customers while providing AeiROBOT with recurring revenue.[1]
Continued NVIDIA collaboration: As an early adopter of Isaac GR00T, AeiROBOT is positioned to benefit from ongoing improvements to NVIDIA's physical AI platform, including advances in large action models (LAMs) that enable robots to interpret high-level instructions and autonomously plan multi-step actions.[8]
