The subject was analysed considering the years involving 2012, when some preliminary tests have been performed together with the software RGBDemo, and 2016, when the company defined a brand new protocol based on SLAM technologies. This acronym for simultaneous localization and mapping refers to numerous robotics methodologies utilised to map “an unknown environment when simultaneously keeping track of an agent’s location within it” . The whole analysis about real-time 3D technologies and archaeology has been based around the free/libre and open-source software program (FLOSS) embedded within the GNU/Linux distribution ArcheOS . In the development of some distinct archaeorobotic devices , open hardware was also made use of or created to be able to optimize the final result and align it to the acceptable standards from the archaeological tolerance . Each of the methodologies taken into consideration is described underlining the limitations and added benefits, thinking of the feedback obtained in the fieldwork. Indeed, each of the proposed technologies have been carefully tested within specialist projects related to archaeology and, additional precisely, to 3D recording of landscapes (survey), structures (excavation) and findings (documentation). 2.
