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.

Abstract: Compositions and methods of protecting plants from cold damage are provided. In particular, the invention provides compositions comprising plant-based nano- and/or micron-sized particles which, when applied to plants or plant parts such as buds, form a non-hydrophilic deposit or film with low thermal conductivity, thereby conferring protection against damage from ice nucleation and cold stress.
