Abstract: A robot system includes a workpiece supplier, a work robot, and a support. The workpiece supplier is to turn a workpiece about a workpiece turning axis to position the workpiece at a work position. The work robot includes a base and a robot arm. The robot arm is connected to the base turnably about an arm turning axis to perform a work on the workpiece at the work position. The arm turning axis crosses the workpiece turning axis. The support connects the workpiece supplier and the base.

Abstract: A jet propelled watercraft includes a watercraft body, an engine in the watercraft body, a jet pump configured to generate a jet thrust by a driving force of the engine, an intake pipe configured to supply air to the engine, an air intake box, and a filter. The air intake box includes a connecting port connected to the intake pipe and an inlet configured to take in ambient air. The filter is disposed in a space in an internal space of the air intake box. The filter divides the space into a lower region and an upper region. The lower region is connected to the inlet and the upper region is located higher than the lower region and connected to the connecting port. The filter is configured to clean air taken into the internal space from the inlet and directed to the connecting port.
