The aim of this article is to present the process of building a programmable robotic manipulator. To do this, first the process of design, manufacture and assembly is presented. Second, the geometric configuration is explained, the active elements of execution, control elements and the mechanical model. Third, to show more about the operation of the corresponding manipulator, cinematics, mathematical models and the amount of work. Fourth, the tests performed to the manipulator are mentioned. Finally, there are three conclusions: a) the identification of optimal physical variables that made the construction of the manipulator; b) change in pneumatic actuators for linear servomechanisms c) the inaccuracies that the manipulator presents in the rotational degree of freedom is solved if the servomotor is changed to one with higher torque, because of inertia, it suffers a delay searching the desired position and oscillates, causing imprecision in the system.
