Grasp detection is a persistent and intricate challenge with various industrial applications. Recently many methods and datasets have been proposed to tackle the grasp detection problem. However most of them do not consider using natural language as a condition to detect the grasp poses. In this paper we introduce Grasp-Anything++ a new language-driven grasp detection dataset featuring 1M samples over 3M objects and upwards of 10M grasping instructions. We utilize foundation models to create a large-scale scene corpus with corresponding images and grasp prompts. We approach the language-driven grasp detection task as a conditional generation problem. Drawing on the success of diffusion models in generative tasks and given that language plays a vital role in this task we propose a new language-driven grasp detection method based on diffusion models. Our key contribution is the contrastive training objective which explicitly contributes to the denoising process to detect the grasp pose given the language instructions. We illustrate that our approach is theoretically supportive. The intensive experiments show that our method outperforms state-of-the-art approaches and allows real-world robotic grasping. Finally we demonstrate our large-scale dataset enables zero-short grasp detection and is a challenging benchmark for future work.
