A3 Ultra is a full-size humanoid robot designed for autonomous service work all day long. The manufacturer lists receiving and guiding visitors, shopping assistance, patrols and monitoring, research and education, data collection and stage performances. It goes to its charging point by itself, connects and disconnects the charging gun, and both batteries can be swapped one after the other. Voice interaction supports many languages; using sound source localisation and vision the robot detects the speaker, turns towards them and addresses users with a registered face by name. Personality, voice, knowledge and skills are configured on the LinkSoul platform, and dances and performances are created on the LinkCraft platform. The robot supports teleoperation with controllers and VR equipment, data collection, managing several robots at once and further development through service drawers in the waist and head. Safety is provided by compliant arm motion, arms stopping when a person stands within reach, obstacle avoidance and a software emergency stop via the app or remote control.

01

Full-size humanoid

A3 Ultra is 174 cm tall and weighs 60 kg. The base version has 51 active degrees of freedom, up to 71 with optional dexterous hands: 2 in the neck, 7 in each arm, 3 in the waist and 6 in each leg. The frame combines magnesium alloy with a carbon fibre reinforced nylon composite.

Up to eight hours on two batteries

1,152 Wh of power in two battery compartments gives up to 8 hours of work in total, measured at an equal share of standing and walking. Actual runtime depends on walking speed and load. It charges directly, by battery swap or automatically, and charging takes at most 2 hours.

Sensors on every side

A 3D LiDAR, a front binocular camera, three fisheye cameras for all round vision and RGB-D depth cameras in the chest and sides let it perceive the space around it. It determines its position to the centimetre with GPS RTK and UWB.

Hears front and back

An eight microphone array front and back, an omnidirectional microphone, speakers, a curved face display and omnidirectional signal lights enable conversation. Sensors on both shoulders detect touch. It connects via Wi-Fi, 4G/5G and Bluetooth.

Hands with up to 20 degrees of freedom

Each hand has 10 degrees of freedom as standard, and models with up to 20 can be fitted. Each arm carries 1 kg rated and 5 kg max. A Thor board handles demanding computing and two RK3588 boards handle basic tasks.
