An autonomous movable apparatus for the treatment of plants with UV light, comprising:
- a mobile base structure configured for unmanned, self-propelled movement along selected paths between rows of plants;
- a panel structure comprising a first set and a second set of panels disposed on opposite sides of the mobile base structure, each of the first set and second set of panels comprising multiple panels articulated to each other, wherein the multiple panels are movable between a rest position in which the multiple panels are folded in a compact configuration and an operative position in which the multiple panels are extended upwardly from the mobile base structure and are oriented with panel surfaces facing in laterally opposite directions with respect to the mobile base structure for treating the plants facing the opposite sides of the mobile base structure;
- an actuator system configured to move the panels between the rest position and the operative position;
- a plurality of UV lamps mounted on the multiple panels, the UV lamps being oriented to face in laterally opposite directions with respect to the mobile base structure for emitting ultraviolet radiation in a germicidal band in laterally outward directions toward the plants when the panels are in the operative position;
- a control system operatively connected to the mobile base structure, the actuator system, and the UV lamps to control autonomous navigation, panel movement of the multiple panels, and UV lamp operation.
