A fruits sorting apparatus includes: a conveyance device configured to convey a plurality of charged fruits from a detection area located on an upstream side to a sorting area disposed on a downstream side; an imaging device configured to photograph the fruits in the detection area of the conveyance device; a processor configured to detect a rotten fruit and a nonstandard fruit having an irregular shape or size based on images of the fruits and vegetables imaged by the imaging device; and a robot configured to pick up the rotten fruit and the nonstandard fruit detected by the processor in the sorting area.

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.

Disclosed are various embodiments of a three-dimensional perception and object manipulation robot gripper configured for connection to and operation in conjunction with a robot arm. In some embodiments, the gripper comprises a palm, a plurality of motors or actuators operably connected to the palm, a mechanical manipulation system operably connected to the palm, a plurality of fingers operably connected to the motors or actuators and configured to manipulate one or more objects located within a workspace or target volume that can be accessed by the fingers. A depth camera system is also operably connected to the palm. One or more computing devices are operably connected to the depth camera and are configured and programmed to process images provided by the depth camera system to determine the location and orientation of the one or more objects within a workspace, and in accordance therewith, provide as outputs therefrom control signals or instructions configured to be employed by the motors or actuators to control movement and operation of the plurality of fingers so as to permit the fingers to manipulate the one or more objects located within the workspace or target volume. The gripper can also be configured to vary controllably at least one of a force, a torque, a stiffness, and a compliance applied by one or more of the plurality of fingers to the one or more objects.

In general terms, the present invention provides a passively compliant robotic arm having one or more variable stiffness joints controllable by first and second bi-directional actuators that can be independently operated. Each bi-directional actuator may be operable in a first configuration to urge the joint in a first direction, and in a second configuration to urge the joint in a second direction opposite to the first direction. The bi-directional actuators may be operated in a cooperating mode (high torque mode) in which they work in tandem (i.e. both in the first configuration or second configuration) to double the available torque output. The bi-directional actuators may also (or alternatively) be operated in a high stiffness mode (antagonist mode) in which they counter-act each other by operating so that they oppose one another (i.e. one in the first configuration and the other in the second configuration). The high torque mode may be utilised for an initial portion of a movement trajectory, and the antagonist mode for a final portion of the movement trajectory. The relatively high stiffness in the high stiffness/antagonist mode results from the combined effects of the non-linear force-deflection relationship of the first and second resilient members. The resilient members may each comprise an elastic element, tendon or other resilient member that can be stretched (elongated) to increase tension therein and thereby urge the joint to move.

This disclosure includes a method for pruning a fruit plant. An exemplary method step includes obtaining an image of the fruit plant that has branches. Next, creating exclusion zones surrounding the branches. Then pruning the fruit plant based upon the exclusion zones.

An end effector includes an imaging device, first and second contact-move members for grabbing a target object, an actuator, and a control device. When, in an image captured by the imaging device, the target object is located within a target-object-grabbing area between a first-contact-move-member-passage area through which a distal end portion of the first contact-move member passes and a second-contact-move-member-passage area through which a distal end portion of the second contact-move member passes in a predetermined-shaped obstacle exclusion area including the target object, the control device adjusts positions of the first contact-move member and the second contact-move member such that the first and second contact-move members pass through the obstacle exclusion area when the end effector moves to a grabbing position.
