 | IsStuck | Condition | Determines if the robot is not progressing towards the goal. If the robot is stuck and not progressing, the condition returns SUCCESS, otherwise it returns FAILURE. |
 | TransformAvailable | Condition | Checks if a TF transform is available. Returns failure if it cannot be found. Once found, it will always return success. Useful for initial condition checks. |
 | GoalUpdated | Condition | Checks if the global navigation goal has changed in the blackboard. Returns failure if the goal is the same, if it changes, it returns success. |
+| IsBatteryLow | Condition | Checks if battery is low by subscribing to a sensor_msgs/BatteryState topic and checking if battery voltage/percentage is below a specified minimum value. |
 | NavigateToPose | Action | Invokes the NavigateToPose ROS2 action server, which is implemented by the bt_navigator module. |
 | RateController | Decorator | A node that throttles the tick rate for its child. The tick rate can be supplied to the node as a parameter. The node returns RUNNING when it is not ticking its child. Currently, in the navigation stack, the `RateController` is used to adjust the rate at which the `ComputePathToPose` and `GoalReached` nodes are ticked. |
 | DistanceController | Decorator | A node that controls the tick rate for its child based on the distance traveled. The distance to be traveled before replanning can be supplied to the node as a parameter. The node returns RUNNING when it is not ticking its child. Currently, in the navigation stack, the `DistanceController` is used to adjust the rate at which the `ComputePathToPose` and `GoalReached` nodes are ticked. |
