<p>A robot of this invention includes: an end effector for holding a substrate in a substantially horizontal state; a vertical driving unit for driving the end effector to move in a vertical direction; a horizontal driving unit for driving the vertical driving unit to move in a horizontal direction; and a rotation driving unit for rotating the horizontal driving unit about a rotation axis extending in the vertical direction. In this case, one end of the end effector is connected with the vertical driving unit. One end of the vertical driving unit is connected with the horizontal driving unit.</p> |
