Motivation
Introduce a new controller that enables flash-based movement with collision checking, ensuring that the agent does not teleport through walls or obstacles during execution.
Modification
Added and registered a new controller: VlnMoveByFlashCollisionController.
Introduced a new config flag: flash_collision to enable or disable collision-aware flash movement.
Updated the VLN default config loading logic to support the new controller and flag.
Use cases (Optional)
Set the
flash_collision=Trueflag inTaskCfgto activate this controller.When enabled, the robot performs flash-based movement but automatically cancels actions that would cause the agent to cross walls or collide with obstacles.
