Abstract
A robot includes a generally cylindrical stationary table adapted to be fixed on a floor, and has an outer peripheral surface formed with a circumferential gear. A rotary table is supported rotatably about the outer peripheral surface of the stationary table. A motor for rotating the rotary table is provided on the rotary table, and is connected to a motor gear meshing with the circumferential gear on the stationary table. An upper arm is supported tiltably on the rotary table, and has an upper end on which a front arm is supported. The front arm carries at its free end a working member, such as a welding torch. Another motor is provided on the upper arm for tilting it. A tension spring is disposed in the stationary table and has one end connected to the lower end of the upper arm, and another end connected to the stationary table at a point thereof about which the rotary table is rotatable. The tension spring serves to reduce the load on the motor which tilts the upper arm.
