Segment of an articulated arm (11) made of composite material, with an elongated shape defining a longitudinal axis (Z), and having a box-like cross section. The segment comprises a first end portion (21), configured for the pivoting of a further segment (15), a second intermediate portion (22) configured for the pivoting of an actuation member (31), and a third end portion (23). The first end portion (21), the second intermediate portion (22) and the third end portion (23) are made in a single body with respect to each other. The second intermediate portion (22) comprises a protruding zone defined by a first side (33) and by a second side (34) converging with respect to each other to define a top (35). Pivoting elements (39) are provided in the protruding zone for the pivoting of the actuation member (31) between the protruding zone and the first end portion (21). The first (33) and the second side (34) defining the protruding zone are filleted to substantially rectilinear adjacent tracts (42, 43) of the first (21) and third (23) end portions. |
