Fecha de publicación: 14/12/2022 Fuente: Wipo "precision agriculture" An illustrative modular smart tool arm (300) operable by a precision agricultural implement (100) includes a mount (310) for coupling the tool arm to the implement, an articulating base (330) including a pair of linkages (342, 344), a lift actuator (346), and linear motion bearings (334) coupling the base to the mount. A unitary backbone member (350) is coupled to the linkages and defines a mount (370) for an agricultural tool (400) and defines a mount (362) for a machine vision module (500).
