AlphaBot 2 by AI² Robotics vs Walker Tienkung by UBTECH

AlphaBot 2 puts a humanoid upper body with more than 34 degrees of freedom on a wheeled base, with a waist-and-leg lift that gives a vertical working range of 0 to 240 cm and 700 mm of reach per arm. Walker Tienkung is a 172 cm, 73 kg biped with up to 42 degrees of freedom, including configurable 7-DoF arms. AI² Robotics has not published AlphaBot 2's height or weight. AlphaBot 2 is built to reach high shelves and low bins, while Tienkung is built to walk like a person.

AlphaBot 2 moves on a wheeled base and uses what AI² Robotics calls 360° × 360° full-space perception to get around; its speed has not been published. Walker Tienkung moves at up to 7 km/h and is built to handle stairs, slopes and uneven ground. Tienkung can go where wheels cannot. AlphaBot 2's wheels suit the flat floors of factories, labs and cleanrooms.

AlphaBot 2 sees through a 360° ring of cameras and stereo cameras, backed by force feedback sensors, a microphone array and proximity sensors. Walker Tienkung combines RGB and stereo cameras with LiDAR, ultrasonic sensors, an IMU and force sensors. Both carry force sensing for handling. Tienkung adds LiDAR and ultrasonic ranging, while AlphaBot 2 adds a microphone array.

AlphaBot 2 thinks with AI² Robotics' GOVLA model, in which a slow System 2 reasons through tasks step by step and a fast System 1 drives whole-body movement, with DeepSeek technology built in. AI² Robotics also says it learns on site from real industrial data without manual reprogramming. Walker Tienkung can run autonomously or semi-autonomously, leaving research teams free to try their own control methods. AlphaBot 2 is a ready-made autonomous worker; Tienkung is a platform for developing new AI.

AI² Robotics rates AlphaBot 2 for more than six hours of continuous work. Walker Tienkung lasts more than 3.5 hours per charge, quick-swaps between two batteries and recharges in 2 hours. AlphaBot 2 lasts longer on a charge. Tienkung's quick swap makes up for it in a lab with spare batteries.

AlphaBot 2 targets automotive, semiconductor and biotech manufacturing, with airports and residential communities planned, and has been shown cooking, doing sterile filling, packing and inspecting. Walker Tienkung is UBTECH's robot for scientific research, education, proof-of-concept projects, logistics trials and rescue research. AlphaBot 2 is a production robot and Tienkung a research one. Choose AlphaBot 2 for multi-step lab and factory tasks over long shifts, or Walker Tienkung for research, education and proof-of-concept projects.

AlphaBot 2's software is AI² Robotics' AlphaBrain embodied-AI platform, updated over the air. Alongside UBTECH's own software, Walker Tienkung supports ROS 2, Python and C++. Tienkung is the more open choice for developers who want to write their own code. AlphaBot 2 improves through AI² Robotics' own model updates.

For work near people, Walker Tienkung has force limiting, collision detection, an emergency stop and a collaborative mode. AlphaBot 2's safety features and certifications have not been published by AI² Robotics. Tienkung is therefore the easier robot to assess for shared spaces. AlphaBot 2's wheeled base does avoid the fall risk of a walking robot.

Walker Tienkung is priced at around $65,000 to $115,000. AI² Robotics has not published a price for AlphaBot 2, so the two cannot be compared on cost directly. Tienkung's value lies in open software, terrain handling and quick battery swaps for research. AlphaBot 2 would need to be quoted against its six-hour runtime and factory task range.
