Abstract: A robotic picking assembly (100) comprising an arm support arrangement (8) configured to move vertically and to rotate about a vertical axis. A horizontally extendable arm (1) is supported in the arm support arrangement. A gripping tool (20) arranged at a free end (1a) of the arm. The arm comprises arm modules (2) linked together in a chain. The arm modules (2) have a pivot means (4) linking adjacent arm modules together in a pivoting manner and a pivot restriction means (15, 16, 18, 19) limiting curving of the arm to only one direction. The arm support arrangement (8) has an arm guiding arrangement (25, 21, 21a, 21b, 33) guiding the arm between an extended position and a retracted position, and an arm drive arrangement (7) configured to move the arm between said extended and retracted positions.
