Wuji Tech teases Wuji Hand 2 with a torque-first bet on robot hands
The Shenzhen robotics hardware company claims 20% better transmission efficiency, but has not disclosed pricing or a shipping date.

Why it matters
Humanoid robotics is moving from demos to supply chains, and dexterous hands are one of the hardest bottlenecks. Wuji Tech's teaser shows a credible technical direction, but buyers still need proof beyond self-reported specs and CGI.
Wuji Tech has teased the Wuji Hand 2, a next-generation dexterous hand for humanoid robots, with company-claimed gains in transmission efficiency and low back-drive torque that point to a specific bet: more useful manipulation through mechanics and motor feedback, not just more tactile sensors.
An Aligned News post on X linked to Humanoids Daily's report and Wuji Tech's own Wuji Hand 2 video. The important caveat is that this is a teaser, not a full commercial launch. Humanoids Daily describes the visuals as computer-generated, and the publicly available material does not include a price, delivery timeline, full datasheet, or independent benchmark.

Wuji Tech, described by Humanoids Daily as a Shenzhen-based hardware developer, already sells the story of its work around hands rather than whole robots. Its website lists the Wuji Hand, Wuji Hand 2, and Wuji Glove. The original Wuji Hand is described on the site as having 20 active degrees of freedom, while the Wuji Glove is presented as a teleoperation and human-computer interaction device with 526 touch points and 120 FPS tactile and pose capture. That pairing matters: Wuji Tech is positioning itself around the interface between human intent, robot control, and the physical world.
What Wuji Tech is claiming
The Wuji Hand 2 teaser says the new hand has a 20% increase in transmission efficiency over its predecessor. The video attributes that to more precise gear meshing, reduced friction across the gear train, smoother torque transfer, and minimal backlash. Wuji Tech also claims back-drive torque has been reduced to 0.05 Nm, a figure meant to signal that the hand can move compliantly when external force is applied.
Those numbers are self-reported in the available material. They are still useful because they show where Wuji Tech wants the market to look. In robotics hands, lower internal friction and better torque transparency can make force control cleaner, especially when the hand is trying to pick up objects with different shapes, weights, and textures. But without a datasheet, test setup, or physical demo footage in the provided sources, the claims should be read as technical positioning rather than verified performance.
Wuji Tech's video says the Wuji Hand 2 "senses torque through current," meaning it appears to infer force through motor current rather than relying primarily on dense physical tactile sensor arrays. Humanoids Daily frames that as a continuation of Wuji Tech's direct-drive, current-based torque-sensing approach. The trade-off is clear: fewer tactile components could simplify the hand and improve robustness, but it also invites the question of how much contact detail the system can capture compared with hands built around high-resolution tactile skins.
The competitive pressure behind the teaser
The timing is not neutral. Humanoids Daily notes that Wuji Tech's teaser arrived in a market where humanoid end-effectors are becoming a visible battleground. In a separate report, the outlet said NVIDIA and Sharpa unveiled an Isaac GR00T reference humanoid platform using Sharpa Wave tactile hands, with more than 1,000 tactile pixels per fingertip, according to that report.
That contrast gives Wuji Tech's announcement its sharper edge. Sharpa is emphasizing tactile density. Wuji Tech is emphasizing mechanical transparency. Both are answers to the same problem: a humanoid robot is only commercially useful if its hands can handle messy, varied real-world objects without crushing, dropping, or misreading them.
Humanoids Daily has also reported that Wuji Tech's foundational technology previously served as a manufacturing baseline for Genesis AI's hardware work, though that claim was not independently corroborated in the provided material. Humanoids Daily's prior coverage is the source for that assertion. What is verifiable from Wuji Tech's own site is narrower but still meaningful: Wuji Tech is building a product stack around dexterous hands and teleoperation, not just publishing a concept video.
For now, the Wuji Hand 2 is best understood as a technical signal. Wuji Tech is telling researchers, robot makers, and potential buyers that it wants to compete on the physical layer of manipulation: gears, friction, torque, inertia, and compliance. The next proof point is not another CGI close-up. It is whether Wuji Tech can show the hand performing under repeatable conditions, publish the specs buyers need, and make the device available on terms robot companies can plan around.
