  • End-effector with rotary actuator for harvesting crops
    Patent number: 11439065
    Abstract: An end effector for harvesting edible crowns of broccoli plants. The end effector may include a body, fingers pivotably coupled to the body, and a rotary actuator disposed in the body. The rotary actuator operably couples to the fingers via one or more linkages and is configured to transition the fingers between an open position and a closed position. In the closed position, an edible crown is retained within the end effector, while in the open position, the edible crown is released from the end effector. A cutting mechanism of the end effector severs the edible crown from a stalk of the broccoli plant. A robotic arm may position the end effector relative to the edible crown for harvesting.
