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.
Claims20
A machine for harvesting edible crowns of broccoli plants, the machine comprising:
- a robotic arm;
- an end effector operably coupled to the robotic arm, the end effector including:
- fingers,
- a rotary actuator configured to transition the fingers between an open position and a closed position, and
- a cutting mechanism disposed on at least one finger of the fingers;
- one or more processors;
- and
- one or more computer-readable media storing instructions that, when executed, cause the one or more processors to perform operations comprising:
- receiving an indication associated with an edible crown ready for harvesting;
- moving, via the robotic arm, the end effector to a position associated with harvesting the edible crown;
- actuating the rotary actuator to transition the fingers to the closed state to retain the edible crown in the end effector;
- actuating the cutting mechanism to separate the edible crown from a broccoli plant;
- and
- moving, via the robotic arm, the end effector to a collection location, wherein at collection location the rotary actuator is configured to actuate the fingers to the open position to release the edible crown.
A method comprising:
- determining an edible crown to harvest;
- moving an end effector to a first position associated with harvesting the edible crown, the end effector having fingers that are configured to transition between an open position and a closed position via a rotary actuator;
- actuating a cutting mechanism of the end effector to cut the edible crow from a stalk, wherein the cutting mechanism is disposed on at least one finger of the fingers;
- and
- moving the end effector to a second position associated with transferring the edible crown.
An end effector comprising:
- a body;
- fingers pivotably coupled to the body;
- a rotary actuator disposed in the body and operably coupled to the fingers via one or more linkages, wherein the rotatory actuator is configured to transition the fingers between an open position and a closed position;
- and
- a cutting mechanism disposed on a finger of the fingers, wherein the cutting mechanism is configured to sever an edible crown from a stalk.
