It generalizes to novel objects and scenes, including cases where prior SoTA models achieve 0% success.\n\n![uploaded image](/media/?type=post\u0026id=96524\u0026key=user_uploads/1366241/6cbcabb4-44fe-4d86-8b20-4b5220709f58)\n\n## The problem\n\nHumanoid robots can do backflips and kung fu, but still struggle with economically useful work. Dexterous manipulation is the main bottleneck to useful physical labor.\n\n## Our approach\n\nWe collect an efficient set of human demonstrations and train a reward model to improve the base model's grasps.\n\n![uploaded image](/media/?type=post\u0026id=96524\u0026key=user_uploads/1366241/86269800-22b9-4a15-bf3c-7d63285ea25d)\n\nThe result is strong generalization: up to 63% gains on difficult objects where the best baselines achieve 0%, while maintaining near-perfect performance on standard objects. Full details are available in our [technical post](https://www.generaltrajectory.com/technical-update).\n\nThe physical world is 80% of global GDP. We believe this research represents progress toward a future in which AI systems are not limited to computer work.\n\n## Open-source\n\nWe open-sourced our teleop stack!\n\n\u003chttps://github.com/GeneralTrajectory/dex-teleop\u003e\n\nIt uses vision + wrist trackers instead of data gloves → about **$500** in hardware vs. **\\~$5,000**.\n\n![uploaded image](/media/?type=post\u0026id=96524\u0026key=user_uploads/1366241/aeeb02d9-821a-44b5-bef0-f491af1fa15a)\n\n## Call to action\n\nIf you are interested in AI for the physical world (scientific R\u0026D, defense, etc.), please reach out!\n\n* Website: \u003chttps://generaltrajectory.com\u003e\n* X: \u003chttps://twitter.com/gentrajectory\u003e","slug":"P6q-general-trajectory-a-foundation-model-for-humanoid-robots","created_at":"2026-01-05T15:51:54.579Z","updated_at":"2026-05-24T21:03:05.999Z","total_vote_count":15,"url":"https://www.ycombinator.com/launches/P6q-general-trajectory-a-foundation-model-for-humanoid-robots","share_image_url":"//bookface-static.ycombinator.com/assets/ycdc/yc-og-image-c440a0ad1dacfb86eeeb343717479cc54d256614449b4ef719977a0a451f8bc8.png","company":{"id":30276,"name":"General Trajectory","slug":"general-trajectory","url":"https://www.generaltrajectory.com/","logo":"https://bookface-images.s3.amazonaws.com/small_logos/4c79fb57c52ab75fc14e93779100504407b5e064.png","batch":"Winter 2025","industry":"Industrials","tags":["Robotics","AI"],"search_path":"https://bookface.ycombinator.com/company/30276"}}
