Abstract: A robotic system (100) for harvesting fruit (12) includes an end effector (102) with a conduit extending between an input port and an output port. A vacuum system (108) coupled to the end effector (102) provides suction to suck an object into the input port. A collection system (110) includes multiple channels that extend along a vertical axis and are positioned in series along a horizontal axis. A positioning system (104) moves the end effector (102) along the horizontal and/or vertical axes and extends the end effector (102) away from the collection system (110) to position the input port near an object (e.g., fruit). Responsive to the object being sucked into the conduit, the positioning system (104) moves the end effector (102) to position the output port at a selected channel of the multiple channels to allow the object to be dispensed into the selected channel The selected channel is closest to the end effector (102) along the horizontal axis.

Abstract: A compact lightweight robotic end-effector has a large range of possible applied force. The end-effector includes one or more underactuated appendages, where each appendage is driven by a single motor connected to a driving cable wound throughout the appendage. The driving cable may be a flat cable or a cable with another non-circular cross section. The driving cable may be wrapped through a series of pulleys and/or bearings within the appendage to reduce frictional losses. The design of the pulley path may allow a desired mechanical response by the appendage, and the mechanical response may be optimized for a grasping process.
