Robora Sim: A PyBullet-Powered Environment for Learning Robotic Physical... Intelligence We are currently building our Robora simulation environment setup for our sim based learning, leveraging PyBullet, an industry-standard physics engine widely used in AI-driven robotics research and development. The environment is optimized with GPU-accelerated learning algorithms, enabling high-speed imitation learning and reinforcement learning within a safe and controlled virtual setup before shipping out to real world. This simulation platform allows our models to learn, adapt, and generalize across different robot morphologies, terrain types and task objectives - all before deployment to the real world. At it's core, the system combines a VLA-powered high-level planner with low-level motion control algorithms, working cohesively to produce emergent, physically intelligent behaviors. This synergy between simulation, learning, and real-world transfer marks a major step forward in our pursuit of adaptive and intelligent robotic systems. Through advanced domain randomization and synthetic data generation, the Robora Simulation Environment ensures that policies trained in simulation transfer effectively to real-world robots, minimizing the sim-to-real gap. Moreover, users will be able to test and integrate their own hardware kits within selected simulation environments in the Robora Dapp, ensuring seamless compatibility and safer real-world implementation.show more

For years Yann LeCun has argued that generative video... models can't truly learn physics. DeepMind's Physics-IQ benchmark proved him right, reporting "a striking lack of physical understanding in current generative video models". The best one scored just 29.5%. This CVPR 2026 paper finds the fix in LeCun's own playbook. "Inference-time Physics Alignment" doesn't retrain the generator. It steers a video model's denoising at inference using a reward from VJEPA-2, LeCun's Joint Embedding Predictive Architecture. - Won first place in the ICCV 2025 PhysicsIQ Challenge with a 62.64% score, beating the previous state of the art by 7.42%. - Repurpose VJEPA-2's "surprise" score as a reward, then search and rank multiple candidate denoising trajectories at test time. - Why it matters: It's a neat vindication of LeCun's thesis. The pixel-prediction generator alone doesn't get physics, but the JEPA world model approach he champions supplies the physics the video model lacks.show more

One warrior. One impossible battle. Only one survives. Created... with Seadance 2.0 on Lart AI Here is the link to try: Prompt: A cinematic, hyper-realistic 12-second action sequence in a ruined modern city at sunset. A fearless female warrior in realistic tactical combat armor faces a towering 40-foot monster with rough stone-like skin and glowing eyes. The monster charges with immense weight, causing the ground to crack, dust to erupt, and nearby vehicles to shake realistically. The woman sprints, slides under a massive punch, and uses momentum to leap from a collapsed concrete slab, delivering a powerful strike with an energy-infused sword. The monster staggers backward with believable body mechanics, destroying a building facade as debris falls naturally under gravity. She performs one final spinning aerial attack, slicing through the monster's glowing core. The giant collapses with realistic physics, creating a massive dust cloud, flying rubble, shockwave, and ground vibration. The woman lands in a controlled three-point stance, breathing heavily as the dust settles and sunlight shines through the smoke. Ultra-photorealistic, Hollywood blockbuster quality, handheld cinematic camera, dynamic tracking shots, physically accurate motion, realistic muscle movement, cloth simulation, debris, lighting, shadows, HDR, volumetric smoke, motion blur, 4K, 60fps, dramatic sound design, seamless action, no cartoon style, no exaggerated superhero physics, every movement follows real-world momentum and gravity.show more

𝗣𝗼𝗽𝘂𝗹𝗮𝗿 𝗼𝗽𝗶𝗻𝗶𝗼𝗻: "𝗝𝘂𝘀𝘁 𝗴𝗲𝗻𝗲𝗿𝗮𝘁𝗲 𝗺𝗼𝗿𝗲 𝘀𝗶𝗺𝘂𝗹𝗮𝘁𝗶𝗼𝗻 𝗱𝗮𝘁𝗮." After working... with many 𝗿𝗼𝗯𝗼𝘁 𝗺𝗮𝗻𝗶𝗽𝘂𝗹𝗮𝘁𝗶𝗼𝗻 teams who've fallen into the simulation trap, here's what I've learned: Simulation teaches your robot to be really, really good at simulation. Unlike blind locomotion policies that can get away with sim-to-real transfer because they rely mainly on proprioception and contact forces, 𝘃𝗶𝘀𝗶𝗼𝗻-𝗴𝘂𝗶𝗱𝗲𝗱 𝗺𝗮𝗻𝗶𝗽𝘂𝗹𝗮𝘁𝗶𝗼𝗻 𝗶𝘀 𝗲𝘅𝘁𝗿𝗲𝗺𝗲𝗹𝘆 𝘀𝗲𝗻𝘀𝗶𝘁𝗶𝘃𝗲 𝘁𝗼 𝘃𝗶𝘀𝘂𝗮𝗹 𝗱𝗼𝗺𝗮𝗶𝗻 𝗴𝗮𝗽. The subtle differences accumulate: - Simulated friction vs real surface textures - Perfect lighting vs shadows, reflections, glare - Ideal object geometries vs manufacturing tolerances - Instantaneous sensor readings vs real-world noise and latency - Clean backgrounds vs cluttered, dynamic environments 𝗧𝗵𝗲 𝗰𝗹𝗮𝘀𝘀𝗶𝗰 𝗽𝗿𝗼𝗴𝗿𝗲𝘀𝘀𝗶𝗼𝗻: Week 1: "Our model works perfectly in sim!" Week 2: "Let's collect some real data to fine-tune." Week 3: "The real data completely contradicts what the sim taught..." Week 4: "Okay, let's collect way more real data." Month 2: "We basically need to retrain from scratch." 𝗧𝗵𝗲 𝗽𝗮𝗶𝗻𝗳𝘂𝗹 𝘁𝗿𝘂𝘁𝗵: There's no shortcut to real-world data collection for vision-based manipulation. Simulation is amazing for debugging, prototyping, safety testing, and of course to supplement your real data. But it's not a substitute for understanding how your robot actually behaves in the actual environment. 𝗪𝗵𝗮𝘁 𝘄𝗼𝗿𝗸𝘀: Use simulation strategically - for exploring edge cases, testing safety boundaries, and rapid iteration. But build your production models on real data from real environments. The teams that succeed treat simulation as a powerful tool, not a magic solution. This is why Neuracore focuses on making real-world data collection so much easier and faster. Because the physics of your actual environment can't be simulated away. 𝗪𝗼𝗿𝗹𝗱 𝗺𝗼𝗱𝗲𝗹𝘀, 𝘆𝗼𝘂 𝘀𝗮𝘆? 𝗪𝗲𝗹𝗹, 𝗽𝗲𝗿𝗵𝗮𝗽𝘀 𝗺𝗼𝗿𝗲 𝗼𝗻 𝘁𝗵𝗮𝘁 𝗶𝗻 𝗮𝗻𝗼𝘁𝗵𝗲𝗿 𝗽𝗼𝘀𝘁! 𝗪𝗵𝗮𝘁'𝘀 𝗯𝗲𝗲𝗻 𝘆𝗼𝘂𝗿 𝗲𝘅𝗽𝗲𝗿𝗶𝗲𝗻𝗰𝗲 𝘄𝗶𝘁𝗵 𝘀𝗶𝗺-𝘁𝗼-𝗿𝗲𝗮𝗹 𝘁𝗿𝗮𝗻𝘀𝗳𝗲𝗿?

In a masterclass at Sequoia Capital AI Ascent, Jim... Fan laid out the "Great Parallel": how robotics is speedrunning the LLM playbook. 🔹 VLA → WAM: Moving from language-heavy models to "World Action Models" that dream in physics. 🔹 Teleop → EgoScale: Replacing manual data with human egocentric video. 🔹 Simulation 2.0: Using neural simulators like DreamDojo to turn compute into environments. "Our generation was born too late to explore the earth and too early to explore the stars. But we are born just in time to solve robotics." He believes that robots will pass the Physical Turing Test in the coming 2–3 years.show more

If you are using an if statement inside a... for loop, did you know there's a better way of doing this is Swift? I'm talking about the where clause. Using the where clause in a for loop can provide several benefits over using an if statement inside a for loop: Readability: It explicitly states the condition that must be met for an element to be processed, making the purpose of the loop clearer to anyone reading the code. Efficiency: When using a where clause, the filtering of elements is done at the level of the sequence, which can be more efficient than filtering within the loop with an if statement. Brevity: Using a where clause often results in more concise code, as it eliminates the need for an if statement and associated braces. This can make the code more manageable and easier to maintain.show more

Multi-robot learning is getting a serious boost! 📚 Researchers... have extended Isaac Lab to train heterogeneous multi-agent robotic policies at scale. The new framework supports high-resolution physics, GPU-accelerated simulation, and both homogeneous and heterogeneous agents working together on coordination tasks. They benchmarked different approaches (MAPPO: Multi-Agent Proximal Policy Optimization and HAPPO: Heterogeneous Agent PPO) across six challenging scenarios and showed that large-scale multi-robot training is not only feasible, but efficient. It’s an important step for real-world robotic collaboration, where teams of robots need to coordinate, split tasks, adapt roles, and interact dynamically, not just operate as identical clones. The code is open-source, and it pushes Isaac Lab closer to what robotics actually needs: scalable, physics-driven environments where many different robots can learn to work together.

🚨 SCIENTISTS MAY HAVE DISCOVERED AN ENTIRELY NEW TYPE... OF MAGNET. It’s called an altermagnet. And it behaves in a way physicists thought shouldn’t be possible. Unlike normal magnets… the material has almost ZERO net magnetism yet it still behaves electronically like a ferromagnet. That means it may combine: • the stability of antiferromagnets • with the speed and functionality of ferromagnets Researchers just observed a giant magneto-optical Kerr effect inside hematite one of Earth’s most common iron minerals. Why this matters: This could open the door to: • ultra-fast memory • low-power computing • next-generation spintronics • advanced quantum materials • AI hardware beyond silicon The strangest part? The magnetism is hidden in the material’s symmetry itself. Not in obvious magnetic alignment. Physics may have just uncovered an entirely new way matter can store and process information. We are entering the era of programmable quantum materials. Follow for more future physics and technology breakthroughs.show more

New nature paper today : Sony's Ace robot beats... 3 of 5 elite table tennis players. Loses to professionals. Human players win points with faster-than-average shots (p<0.001 between won vs returned). Ace wins with ordinary shots. Same speed and spin profile whether it wins or loses the rally (p=0.88). It's playing a completely different sport than the humans are. Trained entirely in simulation. Zero sim-to-real tricks beyond good physics modeling and asymmetric actor-critic (critic sees ground truth, actor sees noisy sensors). Best part — after watching a point, 1992 Olympian Kinjiro Nakamura said: "I didn't think it was possible. But the fact that it was possible... means that there is a possibility that a human could do it too." Code: Paper:show more

🚨 SCIENTISTS JUST WATCHED ATOMS DO SOMETHING THAT LOOKS... IMPOSSIBLE Researchers have directly observed atoms inside a crystal transferring angular momentum and then reversing their direction of rotation. Like microscopic Ferris wheels suddenly spinning the opposite way. Using ultra-powerful terahertz laser pulses, physicists tracked atoms moving in precise circular paths inside a quantum material. But during the transfer process, something bizarre happened: The rotational direction flipped. Physicists describe the effect almost like: 1 + 1 = −1 The reversal comes from the hidden symmetry of the crystal itself a quantum effect never directly observed before. Why this matters: • It reveals new foundations of magnetism • It could help scientists control quantum materials • It may lead to ultrafast future memory devices • It exposes deeper rules governing matter itself The strangest part? The atoms weren’t breaking physics. They were obeying an even deeper layer of it. We are starting to see the hidden mechanics underneath reality.
