  • ROBOTIC SYSTEMS, METHODS, AND END-EFFECTORS FOR HARVESTING PRODUCE
    Publication number: 20170105346
    Abstract: Robotic systems and specialized end-effectors provide for automated harvesting of produce such as fresh market apples. An underactuated design using tendons and flexure joints with passive compliance increases robustness to position error, overcoming a significant limitation of previous fruit harvesting end-effectors. Some devices use open-loop control, provide a shape-adaptive grasp, and produce contact forces similar to those used during optimal hand picking patterns. Other benefits include relatively low weight, low cost, and simplicity.
    Type: Application
