Other forms: rovings
Roving things or people are in motion, like a roving reporter who travels to cover stories instead of staying put at her desk.
Some roving animals are migrating, moving from one point on the globe to another. Roving travelers might be folks who live out of their camper as they wander across the country. And your job might be described as roving, too: "I work as a roving news photographer." Roving comes from the verb rove, "wander," which earlier meant "shoot arrows at a mark selected at random."
