Recently, researchers from the Robotics & Cybernetics Research Group (RobCib) at the Centre for Automation and Robotics (CAR), a joint centre between Universidad Politécnica de Madrid (UPM) and Spanish National Research Council (CSIC), have used a terrestrial robot and an aerial robot to measure temperature, humidity, luminosity and carbon dioxide concentration in the ground and at different heights in a greenhouse. The information collected by both robots allows to know the crop conditions at any moment and to detect problems before it is too late.
The robots supervise the environmental conditions of the greenhouse for 24 hours a day, 365 days a year. Two robots not only can cover a greenhouse in less time than one, but each robot can take advantage of their specific qualities to perform the tasks they do best.
In this case, the terrestrial robot provides robustness, autonomy and fault tolerance, since it can go cross the corridors of the greenhouse carrying its partner for 5 hours. Meanwhile, the aerial robot provides agility and velocity, since it is able to operate at precise times, accessing difficult areas and taking measures at different heights. All this has been successfully tested in simulation and carried out at an experimental greenhouse from School of Agricultural, Food and Biosystems Engineering at UPM.
