The AgiBot A2 Ultra (Chinese: 远征A2 Ultra, Yuanzheng A2 Ultra) is a full-size bipedal humanoid robot developed by AgiBot, a Chinese robotics company headquartered in Shanghai. It is the perception-enhanced flagship variant of the AgiBot A2 series, distinguished from the standard A2 by an expanded sensor suite that includes 3D LiDAR, RGB-D cameras, multiple RGB and fisheye cameras, and an NVIDIA Jetson Orin 64G GPU. These additions give the A2 Ultra more capable autonomous navigation, environmental mapping, and obstacle avoidance than any other bipedal member of the A2 family.
Standing 169 cm tall and weighing approximately 69 kg, the A2 Ultra features 40 active degrees of freedom, 6-DOF dexterous hands with fingertip sensors, and a 200 TOPS AI computing system powered by AgiBot's proprietary WorkGPT multimodal engine. The robot is designed for complex service environments where high autonomy and rich human-robot interaction are critical, including guided tours in large facilities, interactive exhibitions, commercial marketing, and front desk reception. It supports Wi-Fi and 4G/5G connectivity, over-the-air (OTA) software updates, and swarm control for coordinating multiple units simultaneously.
The A2 Ultra gained international recognition by winning a gold medal in group dance performance at the World Humanoid Robot Games, demonstrating coordinated multi-robot choreography.[1] It has also appeared on major Chinese television broadcasts, including CCTV and Hunan TV's 2026 New Year's Eve Gala.[2] Along with the rest of the A2 family, the Ultra shares the distinction of being the world's first full-size humanoid robot certified across all three major global markets (China, United States, and European Union) simultaneously, having received CR, FCC, and CE certifications in May 2025.[3]
AgiBot was founded in February 2023 by former Huawei engineers Peng Zhihui (CTO) and Deng Taihua (CEO). The company's first product, the RAISE A1 (Expedition A1), debuted in August 2023 as a 175 cm bipedal humanoid with 49 degrees of freedom and proprietary PowerFlow joint motors.[4] The A1 served as a technology demonstration platform for industrial applications.
In August 2024, AgiBot introduced the A2 series as its commercially oriented successor to the A1. The initial launch included three variants: the standard A2 for general-purpose service, the heavy-duty A2 Max for industrial handling, and the wheeled A2-W for flexible factory manufacturing. The A2 Lite and A2 Ultra were introduced subsequently to address cost-sensitive and perception-intensive applications, respectively.[5] While the A2 Lite stripped down sensors to reduce costs for entertainment roles, the A2 Ultra went in the opposite direction, adding the most comprehensive sensor and computing stack of any bipedal variant in the lineup.
In May 2025, the A2 series became the first full-size humanoid robot platform to receive safety and quality certifications from China, the United States, and the European Union simultaneously. At the 2025 Zhangjiang Embodied Intelligence Developers Conference, the Shanghai Robot Industrial Technology Research Institute awarded the CR001 certificate to the A2. The platform also holds FCC certification for the U.S. market and CE marking (both CE-MD for machinery and CE-RED for radio equipment) for the European market. These certifications evaluate mechanical and electrical safety, electromagnetic compatibility, functional safety, and intelligent performance.[3]
The A2 Ultra specifically features PLd-level safety protection (Performance Level d, per ISO 13849) and is certified under ISO/TS 15066 for collaborative robot safety. Its three-layer safety monitoring architecture operates at the business, system, and hardware levels, with redundant computing, a dedicated safety center backup, and a dual-path control architecture.[2][6]
The A2 Ultra achieved notable recognition at the World Humanoid Robot Games, where it won a gold medal in the group dance performance event. During the competition, multiple A2 Ultra units performed coordinated multi-robot choreography, with one robot (designated "GUANGZI," empowered by the AgiBot A2 team) appearing dressed as a Terracotta Warrior. The demonstration showcased breakthroughs in artistic expression, precise motor coordination, and multi-unit synchronization using AgiBot's swarm control software.[1][7]
AgiBot made its U.S. market debut at CES 2026 in January 2026, where the A2 Ultra was displayed alongside the full A2 Series, X2 Series, G2 Series, and D1 quadruped series. The A2 Series received multiple "Best of CES 2026" awards, including a Netzwelt Innovation Award 2026 and recognition from MacStories. Bloomberg recognized AgiBot as the top humanoid robot producer globally, based on its estimated 5,168 units shipped in 2025.[7][8]
The A2 Ultra has been featured on several prominent Chinese media platforms. Appearances include CCTV, the 2025 CMG (China Media Group) Science and Innovation Gala, and Hunan TV's 2026 New Year's Eve Gala. These broadcasts demonstrated the robot's capacity for scripted performances, audience interaction, and choreographed movement in live entertainment settings.[2]

The A2 Ultra runs on AgiBot's integrated software stack, which is shared across the A2 family and other AgiBot products. The software ecosystem includes several proprietary components that together enable the robot's interaction, navigation, and task execution capabilities.
WorkGPT is AgiBot's proprietary multimodal AI engine, serving as the core intelligence layer for all A2 variants. It processes text, audio, and visual inputs simultaneously, achieving 96% accuracy even in noisy environments. WorkGPT supports full-duplex conversation (the robot can listen and speak at the same time), a 99% face wake-up rate for proactive greeting when it detects a human face, and retrieval-augmented generation (RAG) for custom knowledge bases. This allows operators to load domain-specific information (product catalogs, facility maps, company FAQs) so the robot can answer contextual questions relevant to its deployment environment.[6][9]
AimMaster is the A2 Ultra's client-side control application, designed for non-technical operators. AgiBot claims the interface can be learned in approximately five minutes. Through AimMaster, users can customize the robot's facial expressions, walking speed, movement duration, and action sequences. Action blocks can be dragged, reordered, and combined to create choreographed routines for performances, presentations, or guided tours. The software also provides scheduling, status monitoring, and remote diagnostics.[2]
The Linksoul platform handles the A2 Ultra's personality and conversational configuration. Operators can customize the robot's knowledge base, wake words, persona, voice characteristics, and greeting behavior through a web interface. This enables rapid adaptation to different deployment contexts; for example, a hotel lobby deployment might use a welcoming, service-oriented persona, while an exhibition deployment might use a product-focused persona with detailed technical knowledge.[2]
The A2 Ultra supports multi-robot coordination through AgiBot's swarm control software. This capability allows multiple A2 Ultra units to operate as a coordinated fleet, sharing navigation data, synchronizing movements, and executing choreographed routines. The gold medal dance performance at the World Humanoid Robot Games was a direct demonstration of this swarm control capability. In commercial deployments, swarm control enables scenarios such as multiple robots providing coordinated coverage across a large exhibition hall or shopping center.[1][2]
AgiBot's Genie Operator-1 (GO-1) foundation model, released in March 2025, introduced the Vision-Language-Latent-Action (ViLLA) framework, combining a Vision-Language Model (VLM) with a Mixture of Experts (MoE) architecture. GO-1 consists of a Latent Planner for general action understanding and an Action Expert trained on over one million real robot demonstrations for high-frequency dexterous manipulation.[10]
The second-generation GO-2 model, released in 2026, uses a dual-system architecture: a low-frequency Semantic Planning Module for high-level reasoning and a high-frequency Action Following Module for real-time motor refinement. GO-2 achieved a 98.5% average success rate on the LIBERO benchmark, outperforming comparable models from NVIDIA and Physical Intelligence.[11]
Genie Sim 3.0 is AgiBot's next-generation robot simulation platform, built on NVIDIA Isaac Sim and unveiled at CES 2026. It provides a complete toolchain for environment reconstruction, scene generalization, data collection, and automated evaluation. AgiBot has released over 10,000 hours of open-source synthetic data through the platform, covering more than 200 tasks with multi-sensor modalities including RGB-D, stereo vision, and whole-body kinematics. The platform includes more than 100,000 simulation scenarios for model evaluation.[12]
Lingqu OS, released in July 2025, is AgiBot's embodied intelligent operating system. It consists of three layers: a real-time middleware layer built on AimRT (a custom C++20 runtime that outperforms ROS 2 in benchmarks), a standardized intelligent agent service layer, and a comprehensive toolchain for simulation, training, and deployment. AimRT's codebase is under 50,000 lines, compared to approximately 200,000 lines for ROS 2, and reduces communication latency by up to 30% in multi-node scenarios.[13]
The A2 Ultra is equipped with 6-DOF dexterous hands as standard. For applications requiring greater manipulation capability, AgiBot offers the OmniHand series as an upgrade path. While the standard 6-DOF hands on the A2 Ultra are suitable for basic grasping, gesturing, and light object handling, the OmniHand series provides substantially greater dexterity for precision manipulation tasks.
The OmniHand 2025 series is AgiBot's standalone dexterous hand product line, available in multiple configurations.

The OmniHand Agile 2025 is notable as the first high-DOF robotic hand priced under 10,000 RMB, breaking the cost barrier for dexterous manipulation in commercial robots. The Pro 2025 variant adds higher fingertip force (up to 25 N versus 5 N), optional 6-axis force/torque sensing, and enhanced tactile resolution, targeting logistics sorting, laboratory automation, and teleoperation workflows. Both models support position/angle mode, torque control, hybrid modes, and velocity operations, with Python and C++ SDKs available for secondary development.[14][15]
AgiBot has demonstrated the OmniHand's capabilities through tasks such as threading a needle, sorting parcels of various sizes and materials on production lines, and performing delicate assembly operations. The hands are designed as modular end-effectors that can be integrated into any robot platform using standard CANFD or RS485 communication protocols.[14]

The A2 Ultra sits between the standard A2 and the A2 Max in terms of technological sophistication, but it occupies a distinct niche focused on perception and autonomy rather than physical strength.
A2 Ultra vs. A2 (Standard): The Ultra adds 3D LiDAR, an RGB-D camera, fisheye cameras, and an NVIDIA Jetson Orin 64G GPU on top of the standard sensor suite. This expanded perception stack enables more capable autonomous navigation, environmental mapping, and obstacle awareness. The trade-off is a lower maximum walking speed (1.2 m/s versus 3.3 m/s for the standard A2) and a lower per-arm payload (~2 kg versus 15 kg). The standard A2 is a generalist for service and retail, while the Ultra targets environments where autonomous operation and environmental understanding are paramount.
A2 Ultra vs. A2 Lite: The A2 Lite strips the LiDAR and RGB-D camera systems entirely, relying on a simplified perception suite to reduce costs (roughly $44,500 versus ~$110,000 for the Ultra). The Lite targets price-sensitive applications like marketing events, exhibition hall performances, and entertainment. The Ultra targets high-value deployments requiring autonomous navigation and advanced AI interaction.
A2 Ultra vs. A2 Max: The A2 Max trades perception for brute force. Standing 175 cm tall and weighing 85 kg, the Max features 53 active DOF, 19-DOF industrial-grade dexterous hands, and a 40 kg payload capacity. The Ultra weighs 16 kg less, walks faster, and has substantially better sensors and computing, but can only carry approximately 2 kg per arm. The Max is a specialist for logistics and heavy manufacturing; the Ultra is a specialist for intelligent interaction and autonomous service.
A2 Ultra vs. A2-W: The A2-W replaces bipedal legs with a four-wheel-drive base, making it a wheeled dual-arm robot weighing 230 kg with a 2,000 Wh battery (5 hours of runtime). The A2-W targets factory floor automation with embodied AI algorithms like UniGrasp and Uni6DPose. The Ultra's bipedal locomotion allows it to navigate stairs, uneven terrain, and human-oriented spaces that wheeled robots cannot access, but with shorter runtime and lower payload.
The A2 Ultra is designed for environments where rich human-robot interaction and autonomous navigation are central requirements. Its expanded sensor suite and NVIDIA Jetson Orin GPU make it particularly well-suited for complex indoor environments with dynamic obstacles and varied interaction scenarios.
The A2 Ultra serves as an autonomous receptionist in hotel lobbies, corporate offices, and government buildings. Using its 99% face wake-up rate, the robot proactively greets visitors when it detects their presence. WorkGPT enables natural bilingual conversation, allowing the robot to answer questions, provide directions, and handle basic service requests. The Linksoul platform allows operators to load custom knowledge bases tailored to the specific venue.
At trade shows, museums, and shopping centers, the A2 Ultra provides guided tours and product demonstrations. Its autonomous navigation capability, powered by HIMUS 3D-SLAM algorithms, enables it to follow predefined routes while dynamically avoiding obstacles and pedestrians. The AimMaster software allows marketing teams to create custom choreographed routines and presentations without technical expertise. Multiple units can be coordinated via swarm control to provide coverage across large venues.
The A2 Ultra's dance choreography support and swarm control make it suitable for staged performances and brand activations. Its gold medal at the World Humanoid Robot Games and appearances on CCTV and Hunan TV demonstrate its performance capabilities. Action sequences can be freely composed in AimMaster by dragging and combining movement blocks.
With Python and C++ API support, ROS 2 compatibility via AimRT, and access to the AgiBot World dataset (over 1 million trajectories), the A2 Ultra can serve as a research platform for embodied AI and human-robot interaction studies. The NVIDIA Jetson Orin 64G provides sufficient compute for running custom deep learning models on-board.
The combination of 3D LiDAR, RGB-D cameras, and L4-level autonomous mobility makes the A2 Ultra effective in large indoor facilities such as airports, convention centers, and hospitals. It can autonomously navigate complex floor plans, ride elevators (with integration), and provide wayfinding assistance to visitors navigating unfamiliar spaces.
The A2 Ultra features a three-layer safety monitoring architecture designed for deployment in environments shared with humans.
| Layer | Function |
|---|---|
| Hardware level | Dedicated safety center backup; dual-path control architecture; emergency stop button; wireless remote emergency stop |
| System level | Redundant computing; real-time force/torque monitoring; collision detection algorithms |
| Business level | Configurable safety zones; speed limiting near detected humans; PLd-level protection per ISO 13849 |
The 360-degree LiDAR and six HD cameras provide comprehensive obstacle detection and proximity sensing. The robot's force-limiting and collision-detection systems comply with ISO/TS 15066 for collaborative robot safety, enabling it to operate in close proximity to humans without physical barriers. An emergency stop can be triggered via the wireless remote controller or a physical button on the robot.[2][3][6]
The A2 Ultra is in active production as of 2026. It is part of AgiBot's broader production program that reached 10,000 cumulative robot shipments by March 30, 2026, doubling from 5,000 to 10,000 in approximately three months. AgiBot projects annual shipments in the "tens of thousands" for 2026.[16]
The A2 Ultra is available for purchase through AgiBot's direct sales channels and authorized distributors. U.S. retail pricing through distributors such as American Satellite is listed at $109,995 USD.[17] Enterprise deployments are typically quote-based and may include customization, installation, training, and ongoing support services.
The robot is available in China, the United States, Canada, Germany, Japan, and South Korea. Colors include white, silver, and black. AgiBot also offers leasing options through its BotShare platform, a robot rental service covering 50 cities across China with plans to expand to over 200 cities by 2026.[7][18]
The A2 Ultra competes in the service-oriented humanoid robot segment, where interaction quality and autonomous navigation are valued over payload capacity.
