Gemma-GR00T: Multimodal Robotic Manipulation with Language Models

Model Description

Gemma-GR00T is a state-of-the-art multimodal vision-language-action policy that combines Google's Gemma language model with NVIDIA's GR00T robotics framework. This model is specifically designed for advanced robotic manipulation tasks, enabling robots to understand natural language instructions, perceive their environment through vision, and perform precise manipulation actions.
