X2 Humanoid Robot

Modular AI Humanoid Platform for Service & Industrial Applications

The X2 Humanoid Robot is a compact, enterprise-ready AI humanoid platform designed for service, research, and light industrial environments. With a human-friendly form factor, modular hardware architecture, and flexible perception options, X2 is built to operate safely and efficiently in spaces designed for people.

The X2 series is available in two configurations — X2 and X2 Ultra, allowing customers to choose the level of sensing, computing power, and expandability that best fits their deployment needs.

Human-Scale Design & Natural Mobility

X2 is designed to balance mobility, stability, and accessibility, making it suitable for indoor environments such as offices, laboratories, showrooms, and controlled industrial spaces.

• Height: approx. 1.31 m

• Compact footprint: 460 mm (W) × 210 mm (L)

• Walking speed: up to 1.8 m/s (typical 0.8 m/s)

• Stable bipedal locomotion with optimized center-of-mass control

Its compact size allows X2 to move comfortably through narrow spaces while maintaining human-like posture and motion.

Dexterous Motion with Modular Degrees of Freedom

The X2 platform provides flexible motion capabilities for interaction, manipulation, and research.

• X2: 25 total degrees of freedom

• X2 Ultra: 30 total degrees of freedom

• Arm DOF:

  • X2: 5 DOF per arm

  • X2 Ultra: 7 DOF per arm

• Waist DOF: 3

• Leg DOF: 6 per leg

This modular DOF design enables smooth upper-body interaction, object handling, and expressive motion.

Perception & Interaction Capabilities

X2 supports human-robot interaction through audio, visual, and touch-based sensing, with enhanced perception available on the Ultra configuration.

Standard Interaction Features (X2 & X2 Ultra)

• Interactive RGB camera

• Head touch sensor

• Microphone array and wireless microphone

• Built-in speaker

• Interactive display with lighting effects

Enhanced Perception (X2 Ultra)

• 3D LiDAR for spatial awareness

• RGB-D camera for depth perception

• Multi-camera layout (front + rear RGB)

These capabilities allow X2 Ultra to operate with higher autonomy and environmental understanding.

Intelligent Control & Computing

Both X2 models are built on a stable embedded computing architecture, with optional high-performance AI acceleration.

• Main compute board: RK3588 ×2

• X2 Ultra additional AI board: NVIDIA Orin NX (up to 157 TOPS)

• Support for OTA updates and mobile app control

• Handheld controller included

X2 Ultra is optimized for advanced perception, autonomous behaviors, and secondary development.

Energy System & Continuous Operation

The X2 platform is designed for practical daily operation.

• Battery capacity: approx. 500 Wh

• Operating time: approx. 2 hours at 0.5 m/s walking speed

• Charging time: ≤ 1.5 hours

• Battery system: direct charging with swappable battery

• X2 Ultra option: auto-charging dock

This enables flexible deployment with minimal downtime.
