AgiBot A3 Ultra Humanoid Robot

Humanoid Robot for Service and Research Tasks

AGIBOT A3 Ultra is a full-sized humanoid robot with a height of 174 cm and a weight of 60 kg, designed for autonomous service scenarios, scientific research, and artificial intelligence system development. Its design features 51 degrees of freedom (DoF) and is capable of carrying up to 5 kg payload per arm. Navigation and spatial orientation are managed by a sensor suite that includes 3D LiDAR, a binocular RGB camera, RGB-D sensors, and panoramic cameras. The NVIDIA Thor computing module, with a performance of up to 700 TOPS, handles artificial intelligence algorithms, while the integrated power system ensures up to 8 hours of autonomous operation.

Main Advantages of AGIBOT A3 Ultra

• Flexibility and precise handling of objects. AGIBOT A3 Ultra features 51 active degrees of freedom with functional OmniHand hands. Its kinematics include 2 DoF in the neck, 7 DoF in each arm, 3 DoF in the waist, and 6 DoF in each leg.
• Manipulation of objects of various shapes and sizes. Each arm is designed for a nominal load of up to 5 kg. The tactile OmniHand hands allow working with both thin sheets of paper and heavier objects within the permissible weight limit.
• 360-degree environmental perception for autonomous movement. The sensor suite with 360° coverage combines 3D LiDAR, a binocular RGB camera, RGB-D cameras, and three wide-angle cameras. They are used for object recognition, terrain assessment, and obstacle avoidance.
• Precise positioning indoors and outdoors. UWB is used for indoor localization, while RTK is used for outdoor precision. The coordinate determination accuracy can be up to ±1 cm.
• High computational performance for complex algorithms. An additional module based on NVIDIA Thor provides computing speeds of up to 700 TOPS. It is designed for autonomous planning, route building, sensor data processing, and intelligent robotic system development.
• Extended autonomous operation. A 1152 Wh battery ensures up to 8 hours of autonomous functioning.
• Expanded capabilities for custom software development. The platform provides software interfaces for motion and navigation control, sensor data acquisition, and audio work. OTA updates and custom software scenarios are also supported.

Mobility and Structure of the Humanoid Robot

The kinematics of AGIBOT A3 Ultra include 51 active degrees of freedom: 2 in the neck, 7 in each arm, 3 in the waist, 6 in each leg, and articulated hands. The 174 cm tall body is made of magnesium alloy and carbon fiber-reinforced nylon, adapting the robot to standard human infrastructure—furniture, work surfaces, and equipment. Each arm is designed for a payload of up to 5 kg, and the peak torque of the knee joint reaches 320 Nm. The model supports several speed modes: from basic walking at 1.2 m/s and everyday movement up to 1.8 m/s to laboratory acceleration up to 2.5 m/s and a special running mode at speeds up to 5 m/s.

Perception System and Navigation

The 360° sensor suite is responsible for environmental perception in AGIBOT A3 Ultra. It includes 3D LiDAR, a binocular RGB camera, three wide-angle panoramic cameras, and RGB-D cameras. The working area is assessed by the camera, while the lower RGB-D camera reads the surface condition and terrain in front of the robot.

Positioning is provided by GPS, RTK, and UWB modules: UWB is used for indoor navigation, and RTK for precise coordinates in open areas. A3 Ultra has basic functionality for map building, localization, point and route following, as well as dynamic obstacle detection and avoidance. Wireless communication is supported via Wi-Fi, Bluetooth, and 4G/5G networks.

Autonomy and Power System

The power supply of AGIBOT A3 Ultra is implemented through a dual-battery system with a total capacity of 1152 Wh. In a mode with a 1:1 ratio of standing to walking time, the comprehensive autonomy reaches 8 hours, but the actual operating time depends on movement speed, load, and specific scenario.

The design supports several modes: direct charging, automatic recharging, and quick battery replacement. Full charging from a 110–220 V network takes no more than 2 hours, and battery replacement takes about 10 seconds. This combination of auto-charging and replaceable power elements is designed for long-term commercial operation.

Computing System and Software Development

The computing complex of AGIBOT A3 Ultra combines three specialized modules with a total performance of up to 700 TOPS. The MDU block based on RK3588 is responsible for motion control algorithms, the HDU module based on RK3588S2 processes head system functions and interaction scenarios, and the ADU computer on the NVIDIA Thor platform implements resource-intensive artificial intelligence models. This is aimed at autonomous task decomposition, dynamic route planning, sensor stream processing, and real-time obstacle avoidance. The platform is fully open for secondary development, providing engineers with direct access to navigation, kinematics, audio system, sensor, and system control interfaces.

Applications of AGIBOT A3 Ultra

• Hotels and HoReCa. For interaction with visitors in restaurants, hotels, and other service spaces. The robot can greet guests, orient them in space, provide consultations, accompany them, and perform auxiliary operations.
• Office spaces. Working with documents, objects, and elements of office infrastructure in a corporate environment. Autonomous navigation helps move between work areas and follow specified routes.
• Retail and restaurants. Tactile hands and machine vision system allow interaction with goods and other items: restocking shelves, demonstrating products, packaging, and providing service support.
• Universities and R&D. A platform for research in humanoid locomotion, autonomous navigation, computer vision, manipulation, and human-machine interaction. Open software interfaces simplify the development of custom algorithms.
• Embodied AI. The NVIDIA Thor computer with a performance of up to 700 TOPS allows working with complex models that process sensor information and control the robot's physical actions. Used for training and testing autonomous behavior.
• Industrial tasks. Automation of operations with parts, equipment, and objects. The selection of specific functions depends on the configuration of manipulators, the working environment, and software.
• Cultural and tourist sites. Information and service tasks in museums, exhibition centers, and tourist locations: from navigation and communication with visitors to working with equipment.
• Demonstration and commercial projects. Full-sized design, multimodal interaction, and autonomous navigation allow presenting A3 Ultra at exhibitions, showrooms, presentations, and interactive spaces.
