Claims9
An articulated robot comprising an elongated arm having a shell-like structure with an open end defining an interior cavity and a module detachably secured in said cavity, said module being comprised of a cylindrical casing having a first axis and containing a motor, transmission means operatively connected to said motor and a driven wrist member operatively connected to said transmission means for rotation about said first axis, said driven wrist member having a projecting portion projecting outwardly of said casing of said module and said open end of said shell-like structure of said arm.
A method of manufacturing an articulated robot which includes at least one first body and one second body supported by the first body for rotation about an axis, the first body including a load-bearing structure, a motor unit carried by the load-bearing structure for rotating the second body, and a rigid outer casing, wherein it includes the steps of forming the rigid casing as a shell-like structure which defines a cavity and also has a load-bearing function, assembling a separate module including the motor unit, and inserting the assembled module in the cavity in the shell-like structure and fixing it thereto.
