Working at height is extremely dangerous because there is not much safety for the worker, for that reason there are accidents of falls from scaffolding. According to the Ministerio de Trabajo y Promoción de Empleo (MTPE) 5.49% are accidents caused in work at heights. It is important to bear in mind that the higher the height there is more possibility of suffering a fall, therefore, there are many factors in the height, the main factor is the air since it does not allow the scaffold to remain still. That is why, this research work proposes the design of a robotic arm with 5 degrees of freedom with Arduino Mega 2560 and a link with Radio Frequency (RF), to replace the worker and reduce the risk of accident, also consider that the robotic arm will be manipulated wirelessly, being ideal to prevent a fall of personnel and controllable from a safe area. It was obtained as a result, that the robotic arm with 5 degrees of freedom is more than enough to perform a cleaning of three types of windows, and the programming for the robotic arm is quite easy and can be programmed very quickly, in addition the SolidWorks software helps to design and layout the robotic arm.
