    • The invention relates to a robot arm and a robot wrist. The robot arm comprises a number N of actuator-driveable joint connections GV
      n which are serially connected via arm links GL
      i , where n = 1, 2,..., N, and i = 1, 2,..., N-1, and N 6, wherein the proximal arm link GL
      1 of the robot arm can be connected to a robot body via the joint connection GV
      1 , the distal arm link GL
      N-1 of the robot arm can be connected to an effector E via the joint connection GV
      N , the arm links GL
      N-1 and GL
      N-2 are connected via the joint connection GV
      N-1 and the arm links GL
      N-2 and GL
      N-3 are connected via the joint connection GV
      N-2 , and each of the joint connections GV
      N , GV
      N-1 , GV
      N-2 allows a movement about an associated axis of rotation R
      GV ,
      N , R
      GV ,
      N-1 , R
      GV ,
      N-2 . The robot arm is configured in such a way that the axes of rotation R
      GV ,
      N-2 and R
      GV ,
      N-1 intersect at an angle in the range from 50 to 130° or the axes of rotation R
      GV ,
      N-2 and R
      GV ,
      N-1 have a minimum distance A1 from one another in the range from 1 mm to 20 mm, the axis of rotation R
      GV ,
      N is arranged radially at a constant distance D1 from the axis of rotation R
      GV ,
      N-1 , and a sensor for detecting a force or a torque about axis of rotation R
      GV ,
      N-1 is present in the joint connection GV
      N-1 .
