Methods and systems for operating a moving platform to determine data associated with a target person or object are disclosed. In an example method to determine at least one of an object or an activity associated with the target, a first moving platform, configured with a first type of sensor, is caused to move to an area associated with the target. The target is located at the area. An attempt is made to determine, via the first moving platform and the first type of sensor, the at least one of the object or activity. Based on the attempt, a second moving platform, configured with a second type of sensor, is caused to move to the area. The at least one of the object or activity associated with the target is determined via the second moving platform and the second type of sensor.
