What is the Xiaqi X02?
The Digit Robotics XiaQi X02 is a wheeled humanoid service robot developed by Digit Robotics, a Chinese robotics firm. Standing 169 cm tall and weighing 69 kg, the X02 is designed for intelligent interaction in public-facing roles such as exhibition guidance, marketing, reception, and product demonstrations. It features 40 degrees of freedom including 29 in its dexterous hands, an embedded high-performance AI compute platform, and a 2-hour runtime. Unlike walking bipeds, the XiaQi uses a wheeled base for stable indoor navigation. Its blue aluminum-composite shell gives it a friendly, approachable aesthetic. Manufactured in China, it integrates electric servo motors and precision harmonic drives, and runs a Linux-based robotics framework likely based on ROS/ROS2. As of 2026, the X02 remains a prototype deployed in limited partnerships and not a commercial-off-the-shelf product.

The XiaQi X02 is not a commercial product, so no MSRP or lease pricing exists. Digit Robotics only provides quotes upon request, and the total cost likely includes hardware, integration, and software licensing. In the broader humanoid market, similar service-oriented platforms from Engineered Arts (Ameca) or UBTECH (Walker S) are often priced in the low six-figures, but direct comparisons are impossible without an official list price. Because the robot is not sold through retail channels, there is no used market and consequently no depreciation curve to analyze. Organizations considering the X02 should budget for custom application development and ongoing support, as the platform’s software ecosystem is immature compared to established alternatives. Until Digit Robotics announces a production version, the robot represents a bespoke investment rather than a commodity purchase.
Who Is It For?
Best for: - Exhibition and event organizers needing an interactive humanoid guide with strong hand dexterity and wheeled mobility.
Not for: - Field robotics or outdoor deployments (wheeled base not suited for rough terrain). - Any application requiring lifting over approximately 2 kg or substantial payload — arm strength is minimal.
Alternatives & Comparison
The XiaQi X02 competes in the niche of guide-and-interaction humanoids, where expressive faces and wheeled stability differentiate it from walking bipeds.
| Model | Price | Available | Key Difference |
|---|---|---|---|
| Engineered Arts Ameca | ~$200,000 (est.) | preorder | Expressive face, no mobility legs; stationary plinth. |
| UBTECH Walker S | ~$150,000 (est.) | enterprise-only | Bipedal walking, 38 DOF, more industrial use case. |
| Fourier GR-2 | Undisclosed (pre-commercial) | preorder | Full bipedal humanoid, 40 DOF, stronger payload. |
Verdict: If you need a wheeled, dexterous humanoid for indoor guided tours with low travel distances and no stairs, the XiaQi X02 is the most practical choice — its wheeled base ensures stability and its 29-DOF hands handle small-item interactions. For purely conversational engagement where expressiveness matters, Ameca is superior. For general-purpose humanoid mobility including walking and potential heavier lifting, the Walker S is the best option despite a higher price and complexity. Until Digit Robotics provides pricing and production readiness, the X02 remains a niche partner-only platform.
Use Cases & Capabilities
Exhibition Guidance & Visitor Reception
The XiaQi X02 shines as a guided tour companion in museums, trade shows, and corporate showrooms. Its wheeled base allows smooth, silent movement across flat exhibition floors, while the 40 degrees of freedom enable natural gesturing and pointing to exhibits. The robot can integrate with a facility’s Wi‑Fi to pull real-time event schedules and answer visitor questions via an external AI language model. With a friendly blue exterior and expressive hand movements, it can hand out brochures or small souvenirs using its dexterous five-fingered hands. The 2‑hour battery life limits continuous operation without a charging dock, but for short, high-impact interactions this is adequate. Because it does not walk, the robot avoids the instability and complexity of bipedal locomotion, making it safer around crowds.
Marketing & Brand Activation
In retail or brand‑activation environments, the X02 serves as an attention‑grabbing product ambassador. Its humanoid form can wear branded apparel and perform scripted routines to engage passersby. The 29‑DOF hands demonstrate fine manipulation, such as holding a sample product or posing for photos. High‑performance servo motors and harmonic drives enable fluid, realistic motion that enhances storytelling. The robot’s onboard AI compute can run perception algorithms to detect audience engagement and tailor interactions. However, the lack of published payload or strength limits its use to light‑touch promotional tasks, avoiding heavy lifting.
Technology Demonstration & Research
Universities and corporate R&D labs can utilize the X02 as a platform for human‑robot interaction (HRI) studies and AI integration research. Its ROS‑compatible framework allows researchers to develop custom navigation and dialogue modules, while the numerous DOF in the hands make it ideal for dexterous manipulation experiments. The wheeled base simplifies motion planning compared to bipeds, lowering the barrier for students. The robot’s relatively small size and 69 kg weight mean it can be moved between labs without heavy equipment. Since the XiaQi is not yet production‑hardened, research institutions may access early‑stage units through a partnership, providing valuable feedback to Digit Robotics. The 2‑hour battery life is sufficient for most lab sessions, and swappable batteries could be engineered if needed.
History & Background
Digit Robotics is a Chinese robotics company that emerged from the country’s growing service robotics sector. The firm launched the original XiaQi concept in the early 2020s, but public records are sparse. The XiaQi X02 was first shown in 2024, unveiled as a second‑generation model with enhanced degrees of freedom (40 total, 29 in hands), a more powerful AI compute platform, and a refined wheeled mobility system. The robot was demonstrated at exhibitions in China, performing as a receptionist and guide. Digit Robotics has not disclosed its headquarters city or founding year, but its domain digit.com.cn suggests a location in China. No known large‑scale deployment has occurred, and as of 2026 the XiaQi remains a low‑volume prototype platform available only to technology partners and research collaborators. The company has not announced any subsequent models or a definitive commercial launch date. Despite the limited availability, the X02’s design—compact, wheeled, and dexterous—positions it as a practical alternative to walking humanoids for indoor service tasks where wheeled mobility is accepted.
Buying Used — What to Check
Verify payload capacity Only 2 kg arm strength is mentioned in spec sheets; essential for any task requiring object handling.
Inspect battery health The 2‑hour runtime may degrade significantly on used units; replacing custom batteries could be difficult.
Confirm software stack maturity As a prototype, autonomous navigation and speech modules may need extensive integration; ensure application-ready functionality.
