Televitis is a R+D+i group of the Institute of Grapevine and Wine Sciences and the University of La Rioja (http://televitis.unirioja.es/en/). Its research activity is focused on precision viticulture and the application of new technologies to vineyard monitoring and plant phenotyping.
Televitis is working on the development of new, non-invasive sensors to monitor key aspects in grapegrowing, such as the yield, grape composition and water status, among others, in fast and non-destructive way.
Among the different non-invasive sensors and technologies used for plant phenotyping and vineyard monitoring, studied and applied by Televitis, can be listed:
• Machine vision
• Multi and hyperspectral sensors
• Chlorophyll-fluorescence sensors
These non-destructive technologies are applied either manual or on-the-go, by installing them in terrestrial and/or aerial vehicles, for vineyard monitoring. In this context it is worth highlighting that Televitis coordinates an European project called VineRobot (www.vinerobot.eu), aimed at developing an autonomous robot with embebed non-invasive sensors, to monitor key parameters of the vineyard.
