RoboTera: Tsinghua's Humanoid Bet Is Now a $1.4 Billion Unicorn

RoboTera spun out of Tsinghua University in 2023 with a single goal: build a full-size bipedal humanoid capable of factory work. By January 2025, the company had raised roughly $140 million at a valuation of approximately 10 billion RMB ($1.4 billion), with Sequoia China leading the Series C. The flagship robot, XBot-L, stands 185 cm tall, weighs 80 kg, and carries 61 degrees of freedom across its full kinematic chain.

The company competes directly with Unitree, UBTECH, and Agibot in China's crowded humanoid market, while drawing comparisons to Western players like Figure AI and Agility Robotics. RoboTera's edge is its Tsinghua pedigree, a proprietary actuator stack, and a whole-body control system developed entirely in-house. With around 200 employees and active factory trial deployments as of 2025, it is one of China's most-watched humanoid startups.

The Tsinghua Connection

Chen Xiaoping spent years at Tsinghua University studying bipedal locomotion and whole-body humanoid control. In 2023, he left to found RoboTera (星动纪元) in Beijing, taking a team of researchers with him. The academic spinout model is well-established in Chinese deep tech, and RoboTera fits the pattern: university lab IP commercialized with venture backing, operating at the boundary between research and product.

The company closed a Series A of approximately RMB 100 million ($14 million) in 2023, then a Series B of roughly RMB 300 million ($42 million) in 2024. The Series C, led by Sequoia China (HongShan) with participation from CITIC PE and Hillhouse, came in January 2025 at approximately RMB 600 million ($83 million). That round pushed total raised above $140 million and established the unicorn valuation at around RMB 10 billion ($1.4 billion).

RoboTera's Tsinghua origins matter beyond pedigree. The university's robotics lab has worked on bipedal locomotion for decades, and Chen's team brought with them deep institutional knowledge of actuator design, gait planning, and whole-body control. The company developed its own quasi-direct-drive actuators rather than relying on off-the-shelf components. Quasi-direct-drive motors prioritize back-drivability and force transparency over peak torque, making them better suited for tasks that require compliant interaction with objects and environments.

Under the Hood: XBot-L Technical Architecture

XBot-L is one of the larger robots in its class at 185 cm and 80 kg. The 61 degrees of freedom break down as: 12 in the legs (6 per leg), 14 per arm (7 per arm), and approximately 21 across the two hands. The 7-DoF hands include tactile sensing in the fingertips for force feedback during manipulation. Payload is 10 kg per hand. Walking speed reaches 6 km/h. Battery runtime is 2 hours.

Onboard compute runs a Qualcomm Snapdragon processor paired with a custom AI accelerator, handling the vision-language-action (VLA) model that drives task execution. The VLA model was trained primarily on teleoperation demonstration data. RoboTera also built the smaller XBot-S in 2025 (approximately 140 cm) targeting service and home-oriented use cases at a lower price point.

XBot-L vs. Competing Humanoids

XBot-L's 185 cm frame is the tallest in this comparison, which matters for reaching high shelves and working alongside standing adults. The 10 kg per hand payload is solid, though it trails Figure 02's 20 kg. At an estimated $80,000, RoboTera sits between Unitree's $16,000 and the $100K+ Western competitors, targeting mid-market Chinese industrial deployment.

RoboTera: The Full Picture

RoboTera's funding timeline reflects the extraordinary pace of capital into Chinese humanoid robotics from 2023 through 2025. The company went from founding to unicorn status in under two years.

Sequoia China (HongShan) leading the Series C carries strategic weight. HongShan has been one of the most active investors in China's humanoid robotics sector, with a portfolio spanning multiple competing companies. Its participation signals confidence in RoboTera's technical differentiation even in a crowded field.

What This Means for China's Humanoid Race

China's humanoid robot sector is the most competitive market in the world right now. Unitree competes on price and iteration speed. Agibot (Zhiyuan Robotics) raised significant capital in 2024 with its A2 platform. UBTECH has the Walker series with Tencent backing. Galbot and a dozen others are all targeting the same factory floor deployment window.

RoboTera's differentiator is technical depth from the Tsinghua lineage combined with a full-stack proprietary architecture. Many Chinese humanoid startups use off-the-shelf actuators. RoboTera's in-house quasi-direct-drive actuators are more expensive to develop but give the company more control over force compliance for assembly tasks.

The 12-Month Outlook

RoboTera's near-term priority is converting factory trials into commercial contracts. The company has been running deployments in Chinese automotive and electronics manufacturing environments. A named contract with a major Chinese automaker (BYD and SAIC have been mentioned in industry reporting as potential partners) would significantly change commercial credibility.

The XBot-S launch expands the addressable market but also stretches the engineering team. Maintaining XBot-L iteration while building out a second platform is a resource management challenge that several Chinese humanoid startups have struggled with. The Series C runway gives RoboTera 18-24 months to execute. The window for establishing a durable position in Chinese industrial robotics is 2025-2026.

Frequently Asked Questions

Where RoboTera Stands

RoboTera has the technical foundation to compete: Tsinghua-derived research depth, proprietary actuators, a full-size bipedal platform with strong specs, and $140 million in funding at a $1.4 billion valuation. The XBot-L numbers are competitive in every category that matters for factory deployment. The company is in active trials with industrial customers.

The challenge is the same one facing every Chinese humanoid startup in 2025: converting promising demonstrations into named commercial contracts before the funding window closes. RoboTera has positioned itself well on the technical side. The commercial side will tell the real story in the next 12 months.
