This research project is to start the development of new tools robotic serving the environment and agriculture. Its purpose is to increase efficiency of operations to perform in natural environments, while contributing to the preservation of environmental goods. To do this, several scientific barriers must be removed, requiring the emergence of a research team brings together multidisciplinary expertise: algorithm for decision support, man / machine interaction, robotics system control and perception. the project proposes to develop an interactive and reconfigurable demonstrator robotic, able to perform precise movements in natural environments with an adjustable degree of autonomy to the situation encountered, and able to interact with operators and bystanders.
