Unified Multimodal Robotic Data

Researchers are developing unified frameworks to handle diverse multimodal robotic data, addressing the challenge of integrating information from various sensors and task specifications. The MUTEX approach, for instance, utilizes a transformer-based architecture to process six different modalities, including video demonstrations, goal images, and speech instructions
