Researchers have developed AttenA+, a new framework designed to improve robotic foundation models by addressing action inequality during training. The framework prioritizes kinematically critical segments of robot trajectories, which are often low-velocity and require precision, by reweighting the training objective based on the inverse velocity field. This physics-aware approach enhances the performance of existing Vision-Language-Action (VLA) and World-Action Models (WAM) on complex tasks and has shown significant improvements on benchmarks like Libero and RoboTwin 2.0.
