Walker X

Overview

Walker X is UBTECH’s advanced humanoid robot platform focused on human-like mobility, interaction, and embodied AI experimentation. The platform integrates autonomous locomotion, dexterous manipulation, semantic navigation, and multimodal interaction capabilities within a compact humanoid form factor intended for research, demonstrations, and future service robotics applications.

Walker X stands 130 cm tall and weighs 63 kg, per UBTECH’s official product page. It has 41 degrees of freedom: 6 per leg, 7 per arm, 6 per hand, and 3 in the neck. Joint torque ranges from 4.5 Nm to 200 Nm. Maximum walking speed is 3 km/h. The robot can handle slopes up to 20°, steps up to 15 cm, and uneven terrain up to 3 cm. Payload capacity is 10 kg carrying, 3 kg two-hand walking, or 1.5 kg single-arm extended, with a 600 mm arm span. The battery is a 54.6V/10Ah lithium pack; charging time is 2 hours with 2 hours of combined working runtime.

Compute runs on dual Intel i7-8665U processors at 1.9 GHz and an NVIDIA GT1030 GPU with 384 CUDA cores. The software stack uses UBTECH’s ROSA framework on Ubuntu with Linux RT Preempt and Android, with Webots as the simulation platform. The perception system is a four-eye configuration with dual RGBD sensors. Navigation uses UBTECH’s U-SLAM with FPV AR navigation and 2.5D obstacle avoidance; localisation accuracy is 10 cm with fine localisation to 1 cm. Connectivity includes dual-band WiFi (2.4/5 GHz), Gigabit Ethernet, EtherCAT, and USB 3.0.

Walker X is classified by UBTECH as a commercial service robot, not an industrial platform. It is positioned for home assistance, office environments, and public service scenarios. UBTECH states it can operate refrigerators, coffee machines, and vacuum cleaners. Walker X has been commercially available since 2021 and is the predecessor to Walker C.
