During the past decade discussions about the way in which the development of technologies can (or should) promote social inclusion processes have been revived in the academic debate, in some cases these have also been reflected in the design and implementation of public policies. However, among the groups of R & D engaged in activities of technological development and extension the deterministic approaches and adherence to the technology transfer models persist and, therefore, they often fail to generate processes of inclusion and sustainable empowerment in the time. The main objective of this paper is to make a first analysis of the learning generated when R & D groups face problems and meanings outside their knowledge production frameworks and the way that enables new forms of negotiation of knowledge and technology, also identifying possible limitations of these processes. To this end, we analyze two experiences of developing technologies for social inclusion in Argentina in the areas of social housing and renewable energy.
