Other embodiments are described.
1. A system comprising:
a picking apparatus comprising at least two grippers, each of the at least two grippers being configured to pick a respective individual crop of crops of a plant,
wherein:
the system is configured to rotate the picking apparatus around a rotational axis of the picking apparatus to move the at least two grippers of the picking apparatus in a rotational path centered on the rotational axis of the picking apparatus; and
the system is configured to stop rotation of the picking apparatus when a first gripper of the at least two grippers is moved to a picking position along the rotational path.
2. The system of claim 1 , wherein:
the plant is a tomato plant; and
each of the crops of the plant is a tomato.
3. The system of claim 1 , wherein:
the rotational axis of the rotational path is within 10 percent of being parallel to a growing bed of the plant.
4. The system of claim 1 , wherein:
an opening width of the first gripper is configured to be automatically adjusted to separate the respective individual crop from at least one other proximate crop of the crops of the plant.
5. The system of claim 1 , wherein:
each of the at least two grippers are adjustable between an open position and a closed position; and
a gripper of the at least two grippers is configured in the closed position to securely hold the respective individual crop when the gripper is moved around the rotational path.
6. The system of claim 5 , wherein:
the gripper is configured to securely hold the respective individual crop in the closed position across different sizes of the respective individual crop.
7. The system of claim 5 , wherein:
the system is configured to stop the rotation of the picking apparatus when the gripper is moved to the picking position of the rotational path; and
the system is configured such that, when the gripper is moved to a release position along the rotational path, the gripper automatically opens to the open position and automatically releases the respective individual crop in a collection device.
8. The system of claim 1 , wherein:
each of the at least two grippers comprise a first claw piece and a second claw piece; and
each of the at least two grippers are configured to pick the respective individual crop by at least grasping the respective individual crop between the first claw piece and the second claw piece.
9. The system of claim 8 , wherein:
for each of the at least two grippers:
the first claw piece comprises a first wedged-shaped tip; and
the second claw piece comprises a second wedge-shaped tip; and
when the first gripper is in the picking position, the first wedged-shaped tip and the second wedge-shaped tip are adjustable to fit around the respective individual crop and to separate the respective individual crop from at least one proximate crop of the crops of the plant.
10. The system of claim 1 further comprising:
a carriage assembly comprising a first rotational mechanism;
at least one imaging sensor; and
a processing unit,
wherein:
the picking apparatus is configured to be coupled to the first rotational mechanism;
the first rotational mechanism is configured to rotate the picking apparatus in the rotational path; and
the processing unit is configured to receive information from the at least one imaging sensor to determine a location of the crops.
11. A method comprising:
providing a system comprising a picking apparatus, the picking apparatus comprising at least two grippers, each of the at least two grippers being configured to pick a respective individual crop of crops of a plant;
wherein:
the system is configured to rotate the picking apparatus around a rotational axis of the picking apparatus to move the at least two grippers of the picking apparatus in a rotational path centered on the rotational axis of the picking apparatus; and
the system is configured to stop rotation of the picking apparatus when a first gripper of the at least two grippers is moved to a picking position along the rotational path.
12. The method of claim 11 , wherein:
the plant is a tomato plant; and
each of the crops of the plant is a tomato.
13. The method of claim 11 , wherein:
the rotational axis of the rotational path is within 10 percent of being parallel to a growing bed of the plant.
14. The method of claim 11 , wherein:
an opening width of the first gripper is configured to be automatically adjusted to separate the respective individual crop from at least one other proximate crop of the crops of the plant.
15. The method of claim 11 , wherein:
each of the at least two grippers are adjustable between an open position and a closed position; and
a gripper of the at least two grippers is configured in the closed position to securely hold the respective individual crop when the gripper is moved around the rotational path.
16. The method of claim 15 , wherein:
the gripper is configured to securely hold the respective individual crop in the closed position across different sizes of the respective individual crop.
17. The method of claim 15 , wherein:
the system is configured to stop the rotation of the picking apparatus when the gripper is moved to the picking position of the rotational path; and
the system is configured such that, when the gripper is moved to a release position along the rotational path, the gripper automatically opens to the open position and automatically releases the respective individual crop in a collection device.
18. The method of claim 11 , wherein:
each of the at least two grippers comprise a first claw piece and a second claw piece; and
each of the at least two grippers are configured to pick the respective individual crop by at least grasping the respective individual crop between the first claw piece and the second claw piece.
19. The method of claim 18 , wherein:
for each of the at least two grippers:
the first claw piece comprises a first wedged-shaped tip; and
the second claw piece comprises a second wedge-shaped tip; and
when the first gripper is in the picking position, the first wedged-shaped tip and the second wedge-shaped tip are adjustable to fit around the respective individual crop and to separate the respective individual crop from at least one proximate crop of the crops of the plant.
20. The method of claim 11 , wherein:
providing the system further comprises:
providing a carriage assembly comprising a first rotational mechanism, the first rotational mechanism being coupled to the picking apparatus and configured to rotate the picking apparatus in the rotational path;
providing at least one imaging sensor; and
providing a processing unit configured to receive information from the at least one imaging sensor to determine a location of the crops.
