TEDAX agents performe explosives handling tasks that require good assistance in handling EOD robotic arms. The interface used for handling explosive devices is relevant for explosive deactivating agents due to the fact that it can ensure greater immersion and performance in their operations. Generally, robotic arms are manipulated by joysticks, keyboard or buttons that are not very intuitive. NUI interfaces are intuitive and provide assistance in robotic arm manipulation. In this study, it is proposed to verify the feasibility of a NUI interface to manipulate EOD robotic arms. The degree of assistance provided by the interfaces through the NASA-TLX method in TEDAX agents of the UDEX-AQP (Unidad de Desactivación de Explosivos de Arequipa) is compared. The compared interfaces are: a MK-2 commercial robot from Allen Vanguard and a NUI interface based on specular Imitation. The tests show that the NUI interface evaluated can be applied in explosives disposal interventions.
