🦾 Why Data, Not Models, Is the Real Moat in Embodied AI
The timing of this question is hard to miss.
This week, the World Humanoid Robot Games released a 2,500+ hour dataset covering 12 scenario categories, 44 operations, and more than 10,000 tasks. Crucially, it also includes failures and edge cases.
But raw hours tell only part of the story.
Zhihu contributor 于超, an assistant professor at Tsinghua Shenzhen International Graduate School, shares his team’s view on why data has become embodied AI’s hardest-to-replicate advantage.
1️⃣ Robot scaling is fundamentally asymmetric
Like language models, robot policies appear to benefit from more data, larger models, and greater compute.
But these three inputs do not scale equally.
Model architectures can be studied and reproduced quickly. General-purpose compute can, in principle, be purchased.
High-quality robot data is different. It must be accumulated through physical interaction, and competitors cannot recreate it overnight.
That asymmetry is what turns data into a moat.
2️⃣ Robot data must be manufactured
LLMs inherited decades of internet data. Robots did not.
Every useful trajectory must be produced through physical interaction. Even a simple cup-grasping task changes with the object, lighting, environment, camera angle, and robot body.
So raw hours are not enough. What matters is the diversity of embodiments, tasks, objects, failures, and recoveries.
Open X-Embodiment needed more than 20 institutions and 22 robot platforms to collect over one million trajectories. DROID used 50 collectors for a year, producing only 350 hours of data.
New methods such as UMI and egocentric recording make collection easier. But every hour still requires real people, equipment, and time.
3️⃣ A successful trajectory can still be bad data
Robot data quality is more complicated than whether a task was completed.
On the hardware side, camera accuracy, encoder readings, force sensors, calibration, communication latency, and synchronization across modalities can all corrupt a trajectory.
The human operator adds another source of noise.
Teleoperating a robot is not the same as performing the action directly. Operators hesitate, pause, readjust, and develop habits for compensating for the control system.
A task may succeed even when parts of the demonstration should never be imitated.
Success is therefore only the coarsest possible label. One trajectory can contain both excellent behavior and inefficient or misleading actions.
Training on the entire trajectory without distinction effectively tells the robot to learn both.
4️⃣ The next challenge is information density
Collecting more trajectories is only half the problem. Teams must also identify which parts are worth learning from.
Yu Chao’s team developed STEAM to detect local progress within a trajectory without frame-by-frame annotation or manually designed rewards.
It separates useful progress from hesitation, failure, and recovery.
The key question is shifting from “How many trajectories do we have?” to “How much useful information does each trajectory contain?”
5️⃣ Embodied data is physically expensive
Text can be copied. Videos can be downloaded.
Robot data requires a physical production process.
Collecting one hour may involve a robot, sensors, teleoperation equipment, an operator, a suitable environment, task materials, and engineers who maintain and calibrate the system.
Real factories, stores, and homes add even more complexity.
And pressing the record button is only the beginning. Transmission, cleaning, governance, and storage can cost more than collection itself.
The author offers a rough calculation.
If a company wants one million hours of real-world data and reduces the combined collection and management cost to RMB 200 per hour, the total still reaches RMB 200 million.
🔑 The real moat compounds over time
Quantity, quality, and cost explain why embodied AI data cannot be replicated through a short burst of spending.
Large, diverse, high-quality datasets require physical infrastructure, operational discipline, and years of accumulation.
As robot policies continue to benefit from scaling, the durable advantage will belong to teams that can repeatedly:
🔹 Collect broader real-world experience
🔹 Identify the most informative behavior
🔹 Preserve failures and recovery signals
🔹 Turn noisy trajectories into useful learning data
In embodied AI, having data and knowing how to use it are becoming two very different capabilities.
And the second may ultimately matter even more than the first.

AI CONFERENCES AND INVESTOR DAYS, THURSDAY, OCTOBER 15, 2026
YESTERDAY: INVESTOR DAY TAKEAWAYS
ACCENTURE PLC INVESTOR DAY
Wed Oct 14, New York
Replay:
• New FY27 to FY29 framework from the 8-K financial presentation: mid-single digit revenue growth in local currency in FY27 and FY28, stepping up to mid-to-high single digits in FY29, with 10 to 30 bps of annual operating margin expansion; FY27 guidance reaffirmed at 3% to 6% local currency revenue growth, with acquisitions adding about 2% to 2.5%
• FY26 base: revenue $74.2B, adjusted EPS $13.97, adjusted operating margin 15.8%, free cash flow $11.6B, bookings $84.5B for a 1.1 book-to-bill, and a record $11.5B returned to shareholders; about $5.5B of buybacks expected in FY27 and at least $9.5B of shareholder returns guided for FY27
• AI answer to the bear case: a $3 trillion addressable market was framed, a joint forward deployed engineering program with Workday for agentic AI in HR and finance was launched, and the UK customer and data intelligence firm Sagacity was acquired for Accenture Song; the Anthropic partnership announced Sep 18, at least $1B from each side over 5 years, was the backdrop
• Stock reaction: shares rose about 4% premarket and about 2% intraday, then faded to close up 0.7% at $214.96; the stock is still down about 20% year to date after the roughly 16% rally on the Oct 1 results
• Analyst reaction: UBS reaffirmed Buy with a $275 target, citing doubled emerging alliance revenue and more than tripled Q4 bookings; the cautious read is that the targets are an ambition, not proof, and FY27 has to deliver the first leg
SAILPOINT INC INVESTOR DAY
Wed Oct 14, 12:00 PM ET, virtual
Replay:
• No guidance or financial update, by design: the Oct 14 analyst and investor webcast was a product recap of Navigate, Austin Oct 5 to 8, and management said at the outset it would not discuss the financial impact of the products; replay is on the IR site for 1 year
• The recap centered on autonomous identity security for the agentic era: three classes of Autonomous Agents that monitor runtime actions, enforce policy and right-size privileges, plus Autonomous Identity Security Posture Management for continuous exposure detection and real-time remediation in Atlas
• Expanded Agentic Fabric maps the full AI agent surface area, with shadow AI discovery, runtime authorization and an instant kill switch; Human Fabric advances human identity governance; Zero Standing Privilege via just-in-time provisioning now covers humans, service accounts and AI agents
• The demand framing: 79% of enterprises are already running AI agents in production, yet only 2% have deployed identity tools purpose-built to govern them, per the Horizons of Identity Security report
• Stock reaction: shares closed down 0.4% at $19.30 on the day; Piper Sandler maintained Buy with a $25 target on Oct 14, with consensus at Buy and an average target near $21.88
