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.

Abstract: A robot includes a work tool, an arm, a cable, and a third member. The work tool is configured to perform a predetermined work with respect to a workpiece. The work tool is attached to the wrist. The arm supports the wrist and is rotatable around a rotational axis. The arm includes first and second members which are provided substantially in parallel to each other in a longitudinal direction of the arm to form a space between the first and second members. The cable extends through the space and is connected to the work tool. The third member connects the first and second members.
