A robot with multi-joint arms, wherein articulated first and second arms 9, 10 are movable in a horizontal plane as well as in a vertical direction, the second arm having a free end to which a supplementary unit A is removably connected, the supplementary unit A including a joint member 17 adjustably connected to the free end of the second arm 10 and a working member 18 removable connected to the joint member 17. The working member 18 has a predetermined length Lx which determines the effective length L2 of the second arm 10, and wherein the data representing the effective length L2 of the second arm is entered to renew the existing effective length of the second arm to produce new data representing the value of the newly entered effective length L2 of the second arm 10, the new data being employed to calculate out the value to control the operations of the first and second arms 9, 10.
