PathTime-VLA: Path-Time Decoupling for Factorized Post-Training of Vision-Language-Action Policies
Vision-Language-Action (VLA) policies typically predict actions at fixed time intervals, coupling the route a robot follows with its execution pace. This coupling complicates adaptation from teleoperation: useful geometric guidance comes with timing shaped by interface delays and operator behavior. Our key insight is t …
