Abstract: In view of the single mode of agricultural information acquisition technology and mode used in agricultural production at the present stage, and the problem that one mode of acquisition can not adapt to a variety of environments, a robot which can be used to collect agricultural information both on the ground and in the air is proposed. The new agricultural information acquisition robot is a new type of ground-air dual-purpose robot which combines the ground walking robot with the Four-rotor UAV. When collecting the ground information, it collects the information by walking. When encountering obstacles that cannot be avoided, it collects the information by flying. When the positioning device is unable to collect the information, it uses hovering mode to do so. Information collection. According to the requirement of this kind of use, an information acquisition system is designed to collect information and monitor the process by various sensors or cameras, which can realize the real-time transmission of the process acquisition information, and collect information from different angles in the process of use, so as to realize the multi-direction information acquisition in the process of agricultural production. The software and hardware system of the ground-air dual-purpose agricultural information acquisition robot has been developed.
