DrJimFan introduces GR00T 2, promising robot control without the tether

GR00T 2 keeps its control model onboard the robot, according to DrJimFan, who says it can chain tasks across 20-plus steps and five-plus minutes, including chemistry experiments and model-airplane assembly. The release calendar has a split: his announcement puts weights and X-Adapt recipes in December, while the agent framework, simulation engine, hardware design and 100,000 hours of training data are available now.
