Looking for feedback on my physical AI setup. Currently it’s: - OpenArm bi-manual body (Japan 🇯🇵) - Diver-X tactile haptic glove (Japan 🇯🇵) - AGIBot robot hand (China 🇨🇳) What is everyone else using?

I was really impressed by the UMI gripper (Cheng Chi et al.), but a key limitation is that **force-related data wasn’t captured**: humans feel haptic feedback through the mechanical springs, but the robot couldn’t leverage that info, limiting the data’s value for fine-grained manipulation tasks. Led by my amazing students Yolanda Zhu and Binghao Huang, we designed a **portable visuo-tactile gripper** by integrating our dense, flexible tactile arrays with the UMI gripper to enable large-scale in-the-wild data collection. 🔗 We demonstrate **cross-modal representation learning** and **downstream policy learning** on tasks requiring in-hand state estimation (e.g., test tube reorientation) and fine-grained force sensing (e.g., pipette fluid transfer). Key takeaways: - Our flexible tactile arrays store the rich haptic information humans perceive as dense tactile signals. - Portability and robustness are key for in-the-wild data collection; our portable gripper is compact, lightweight, and durable. - Touch provides precise, robust measurements of in-hand object pose, invariant to lighting and viewpoint. - Cross-modal pretraining on large-scale in-the-wild data significantly improves policy robustness and sample efficiency (as shown many times before — and verified again here!). Also check out our previous investigations of dense, flexible tactile grids for understanding human-robot-environment interactions: - Dense tactile glove (Nature ’19): - 3D-ViTac (CoRL ’24):

🇯🇵 Why Japan’s Decline Is Psychological, Not Just Economic Everyone talks about Japan’s economic stagnation — lost decades, shrinking influence, declining industries. But there’s a deeper layer almost nobody touches: Japan’s geopolitical identity crisis is inseparable from its hostility toward China. Not because China threatens Japan. But because China shattered the psychological structure Japan has lived inside for 80 years. 1. Japan once believed it understood how Asia should work. Modern Japan’s national mindset is built on one story: • The U.S. defeated us. • The U.S. rebuilt us. • The U.S. protects us. • The West accepts us as the “civilized Asian,” the honorary white nation. Japan internalized this hierarchy. And then it projected the same logic onto China. Japan slaughtered 35 million Chinese. Ran Unit 731. Used women as sexual slaves. But Tokyo always believed: “I am richer, I am more advanced, I have better reputation. So China should ‘move on’ the same way I moved on under U.S. rule.” Japan thought dominance creates obedience. Because that is how it behaved toward America. 2. When China was weak, Japan mistook silence for acceptance. For decades, China didn’t have the power to push back internationally. Japan interpreted this as: • “China accepted our narrative.” • “China doesn’t dare confront us.” • “The war is over — we won the moral argument.” This is absolutely not reconciliation; it is merely a power illusion. Japan became comfortable believing: “If China must bow to someone, it should bow to me, just like I bowed to America.” 3. Then China rose — and Japan’s entire worldview collapsed. China didn’t just grow. China overtook Japan in every pillar of national power: • GDP • Manufacturing • Technology • Diplomacy • Military • Global influence China now competes with the United States itself — the very empire Japan historically imitates. And this is where the psychological rupture begins: Japan cannot emotionally process a world where China stands on the same level as America. Because in Japan’s internal hierarchy: • America is the master. • Japan is the apprentice. • China is supposed to be below both. But suddenly… the “student of America” watches the “victim of Japan” surpass them both in power and prestige. For many Japanese nationalists, this feels like an existential insult: “How dare China rise to the level of my master? How dare China erase the hierarchy that defines me?” So the hatred intensifies. Not just political hatred — existential hatred. 4. And the irony? China never asked Japan to kneel. China only asked Japan to face history. But to Japan, acknowledging history means acknowledging loss of superiority. So instead, resentment grows. And Japan’s geopolitical relevance shrinks even faster. 5. Japan’s economic decline is inseparable from this psychological stagnation. - While China built entire industrial ecosystems, Japan clung to nostalgia and Western validation. - While China out-innovated, out-built, out-scaled, Japan obsessed over keeping China “in its place.” Japan’s decline is not just economic, it is a refusal to accept a world where it no longer defines Asia.

🔥 JUST IN: Open-source robotics dataset from 100% real-world scenarios! 🤯 Chinese robotics company AGIBOT just released AGIBOT WORLD 2026, an open-source dataset systematically covering key embodied AI research directions. Built entirely from real-world environments: commercial spaces, and homes. Collected using AGIBOT G2 robots in free-form collection mode, providing structured, accurately annotated, high-quality data. Digital twin technology creates 1:1 scale replicas in simulation matching the real environments. Both real-world and simulation data are open-sourced. The AGIBOT G2 platform collects multiple data types simultaneously: RGB(D) cameras, tactile sensors, force sensors, LiDAR, IMU, and full-body joint states. Whole-body control coordinates arms, waist, and hands for complex tasks. First-person teleoperation lets operators control the robot from its perspective. The tasks covered are fine-grained manipulation, ultra-long-horizon tasks, spatial navigation, dual-arm coordination, and multi-agent/human-robot collaboration. The dataset includes error-recovery trajectories with annotations. Most datasets only show successful demonstrations. AGIBOT includes failures and how the robot recovers, teaching models how to handle mistakes. After collection, data is tested through policy training and real-robot deployment to ensure quality. Then processed through industrial quality control with multiple screening and cleaning rounds. Making it open-source accelerates embodied AI research by giving researchers access to high-quality real-world robot data at scale. 🇨🇳 Learn more here: ~~ ♻️ Join the weekly robotics newsletter, and never miss any news →

🇯🇵 Here’s the part Western and Japanese media keep pretending not to understand: China’s response to Sanae Takaichi isn’t about one remark. It’s about a defeated Axis power testing the boundaries set for it in 1945, and Beijing reminding the world that those boundaries are still there. The video below is from Gao Zhikai, former interpreter for Deng Xiaoping and one of China’s most respected geopolitical commentators. His point is simple: Japan crossed a red line it had no right to touch. Takaichi’s “Taiwan = survival-threatening situation for Japan” rhetoric isn’t diplomacy. It repeats the same logic Japan used in 1931 (Manchuria) and 1941 (Pearl Harbor): manufacturing a “security threat” to justify military expansion. And Beijing’s message is blunt: Don’t play with fire. Don’t pretend Japan has the legal or moral standing to interfere in a conflict with China. Repeat your old mistakes, and you will repeat the consequences. China’s position rests on international law: • Unconditional surrender (1945) — Japan cannot reinvent its military role. • Post-war constitution — SDF ≠ permission to join foreign wars. • UN enemy state clauses — Trigger them, and China can act militarily without UNSC approval. • 1971 Joint Communiqué — Japan formally recognized that there is only one China. So what is China actually doing? Not “overreacting.” Not “misunderstanding Japanese language.” But forcing Japan to fill the hole Abe Shinzo dug, a decade of flirting with remilitarization and pretending WWII never ended. This moment is Beijing’s reminder to the entire world: Taiwan is not a toy. Not a bargaining chip. And absolutely not a stage for Japan’s historical amnesia. On the surface, China demands an apology. In reality, it’s a clear reconfirmation of Japan’s status: Japan is a defeated nation. It still is today. And one reckless statement won’t overturn that ever.
