## Key facts

- **MARBLE amphibious sphere robot (project-stated, Sep 2026):** Project-stated ([project-stated](https://arxiv.org/abs/2609.27358); [project site](https://generalroboticslab.com/MARBLE)): Duke University General Robotics Lab paper introduces [MARBLE](/models/duke-marble.md), a fully enclosed omnidirectional amphibious rolling robot driven by internal mass redistribution (Weaver / Xia / Lo / Huang / Chen; arXiv 2609.27358). Academic research platform; software and hardware designs stated to be open-sourced. Cap: research demo, not a commercial product
- **Physical intelligence mission:** Duke's General Robotics Lab says it studies physical intelligence, the ability of systems to understand, interact with, adapt to, and transform the physical world, and builds machines that learn from real-world interaction ([General Robotics Lab](https://generalroboticslab.com/)).
- **Research pillars and featured robots:** The lab lists pillars for understanding physical systems, embodied intelligence, collective intelligence, and scientific intelligence, and features work on a modular aerial-ground platform, a 7-DoF Cartesian hand with all-linear fingers, and the Duke [Humanoid](/humanoids) for energy-efficient bipedal walking ([General Robotics Lab](https://generalroboticslab.com/)).
