Several versions of the robot were discarded until the final design was obtained after modifying the wrist because the leg was not able to put its final end parallel with any surface. The solution was to add a new DoF to the wrist, which allowed it to rotate on its main axis, achieving the total positioning of the final part of the wrist.

The main objective is to capture the robot in the mentioned simulator, giving it its characteristics. Since this robot will have the complex task of inspecting ducts with difficult or no access it is necessary that the simulated model responds correctly to the different unforeseen events that may be in its way.
