Researchers at Meituan developed RoboTron-Mani, a multimodal large model that integrates 3D spatial perception and flexible outputs for robotic manipulation, along with RoboData, a unified and aligned dataset. The system achieves strong performance across diverse robotic manipulation tasks in both simulation and real-world environments, often matching or exceeding specialized expert models.
Key insights
- Integrating advanced 3D perception, specifically through a unified 3D view representation and occupancy supervision, significantly enhances a multimodal model's ability to perform robotic manipulation.
- Meticulous alignment of heterogeneous robotic datasets, including 3D spatial coordinates and action representations, is crucial for successful joint training and achieving strong generalization across diverse tasks and platforms.
- Employing multimodal outputs (actions, next-frame images, occupancy maps) with flexible supervision mechanisms (Modality-Isolation-Mask) improves overall action performance by providing richer contextual information during training.
