The invention relates to a robot arm (1) comprising at least two arm joints (21, 22) which are pivotally connected together and which are driven directly. The aim of the invention is to reduce the energy required to move the parts when pivoting the arm joint and allow an uncomplicated adaptation of the robot arm to changed use conditions. This is achieved in that at least one of the two arm joints (21, 22) has a motor part (3) and a joint part (4), wherein the two parts (3, 4) are arranged in a mutually spaced manner via a spacer part (5), and the other arm joint (22) is arranged so as to engage with the spacer part (5) of the arm joint (21) such that the position can be changed relative to the arm joint (21).
