Short Review
Overview
The article introduces the D2E (Desktop to Embodied AI) framework, which innovatively utilizes desktop data for pretraining embodied AI. This approach addresses the challenges associated with the high costs of physical trajectory collection by leveraging rich sensorimotor interactions found in desktop environments, particularly gaming. The framework comprises three main components: the OWA Toolkit for standardized data capture, the Generalist-IDM for effective event prediction and pseudo-labeling, and VAPT for transferring learned representations to robotics. The findings demonstrate impressive success rates of 96.6% in LIBERO manipulation and 83.3% in CANVAS navigation tasks, validating the potential of desktop pretraining for robotics applications.
