                         this work it is investigated the modelling of a robotic system in 
                         a space environment, taking into account the disturbances caused 
                         to the satellite attitude resulting from torques generated by 
                         actuation of the robotic mechanisms during berthing between 
                         artificial satellites. The movement of the robot base, due to 
                         repositioning of the satellite through its actuators, dynamically 
                         changes the distance from the target. The robotic arm that serves 
                         as the object of study in this work consists of a revolute 
                         manipulator with three rotating joints and three degrees of 
                         freedom in configuration Torsional - Rotational - Rotational (TRR) 
                         moving in space. Such configuration confers diverse applicability 
                         and notable usefulness in performing on-orbit servicing. The 
                         mitigation of positioning errors caused by rotation and 
                         translation of the artificial satellite and those from movements 
                         of extension, flexion and rotation of the robotic apparatus 
                         coupled to the satellite, allows us a clearer insight about the 
                         necessary strategies for the future use of this technology. The 
                         analysis suggests that the development of models that consider the 
                         dynamic correction of positioning errors and simultaneous, as well 
                         as cooperative, operation of the artificial satellite's and 
                         robot's control systems provides advantages in such missions.",
