a second cover fixed to the movable arm of the robot, the second cover configured to block the cover opening portion without a gap to enclose the robot inside the first cover and the second cover.

2. The robot system according to claim 1, wherein

the robot is a vertical articulated robot.

3. The robot system according to claim 2, wherein
