Product overview
About AeiROBOT Alice 4
Alice 4 is a bipedal humanoid from AeiROBOT, a South Korean robotics company. AeiROBOT's event report says the fourth-generation Alice was newly shown at RobotWorld 2024, held from 23 to 26 October, and received an award in the personal-service-robot category. At CES 2026, Korea Herald reported that Alice 4 recognized a tumbler, placed it in a box and adjusted its grip while the wheeled Alice M1 moved the organized items to a conveyor.
AeiROBOT lists Alice 4 at 160 cm, about 45 kg and 41 degrees of freedom. The total comprises two 6-DoF legs, two 7-DoF arms, two 6-DoF hands, a one-DoF waist and a two-DoF head. An AeiROBOT and Hanyang University team specification submitted for RoboCup 2025 gives a 1.0 m/s omnidirectional walking speed and four 140.4 Wh batteries, while noting that the design remained under development.
The robot uses AeiROBOT's proprietary linear actuators, an Intel Core i7-1370PE control computer and NVIDIA Jetson Orin NX perception compute. Officially listed sensors include a stereo depth camera, a six-axis IMU and foot force sensors.
In October 2025, AeiROBOT said Alice 4 was being deployed in shipbuilding and construction for large-scale field trials. No general order page or public price is available, so the robot is classed as a pilot.
