The aim of this paper is to analyze the social representations of material culture associated with the harvest of cocoa, of afro-descendant women of the community Panaquire (Miranda State, Venezuela). It will deepen the local knowledge that they have of this productive activity, which involves a large part of their material culture, while making social choices and actions, as essential components of a particular technological system. We have used the theoretical perspective of social representation of technology (Lemonnier, 1992:4), since it facilitates understanding and systematizing the knowledge, skills and experience of the panaquireña women. With this we intend to demonstrate the importance of women in cocoa production, since they are the ones who give social cohesion to this production process. This research is based on fieldwork conducted in Panaquire, between 2010 and 2013, where we applied methodological tools such as participant observation and open and semi-structured interviews of older women of the community.

Past literature has reported many successful cases about crops in greenhouses. The main function of greenhouses is to recreate and keep adequate and controlled conditions of light, humidity, temperature, carbon dioxide, and pesticides, among others, in a confined space to grow plants for diverse purposes. However, those conditions can be potentially harmful to humans that work in greenhouses. An alternative to overcome this is the application of robotics in those agricultural sites, adequately applying artificial intelligence and mechanical subsystems that are part of a robot. This paper describes a literature review of research and development of robots used in activities such as spraying pesticides and for harvesting in greenhouses. [ABSTRACT FROM AUTHOR]
