  "abstract": "A door opening/closing robot includes: a base provided at a position different from a conveyance line on which a vehicle body is conveyed; a first arm attached to the base to rotate around a first axis and extending away from the first axis; a second arm attached to the first arm to rotate around a second axis and extending away from the second axis; a third arm attached to the second arm to rotate around a third axis and extending away from the third axis; and a fourth arm attached to the third arm to extend vertically and configured to vertically move a tool for holding a door of the vehicle body. At least a portion of a connection area including a distal end of the second arm and a proximal end of the third arm is positioned at a same height as at least a portion of the base.",
