一只软手13个传感器，康奈尔大学团队造出能看会摸的采摘机器人，登《Nature》子刊

Core Viewpoint - The article discusses advancements in agricultural automation, specifically focusing on a new robot developed by a research team at Cornell University that can effectively pick strawberries using integrated sensory technology, addressing the challenges of traditional harvesting methods [1][5]. Group 1: Challenges in Strawberry Harvesting - Strawberry harvesting is complex due to the short maturity window and the delicate nature of the fruit, which can easily bruise or spoil if not handled properly [5]. - Traditional harvesting robots struggle with visibility and grip, often relying solely on cameras or rigid claws, leading to potential damage to the fruit [5][6]. Group 2: The Innovative Robot Design - The robot features a soft, 3D-printed silicone hand with five fingers, designed to minimize the risk of damaging the fruit during harvesting [6][10]. - It incorporates 13 sensors, including touch sensors in the fingertips and joint sensors for bending perception, allowing it to assess fruit firmness and adjust grip strength accordingly [6][8]. Group 3: Sensory Capabilities - The robot's hand includes a micro-camera and distance sensors for visual assessment, achieving nearly 100% accuracy in shape recognition and less than 1.8% error in size measurement [8]. - Touch sensors utilize optical fibers to detect fruit hardness, providing real-time feedback on the fruit's condition [8][10]. - The system combines visual and tactile data, enabling the robot to make accurate harvesting decisions even in varying light conditions [16][19]. Group 4: Practical Demonstration - The robot successfully demonstrated its ability to pick strawberries by identifying ripe fruit and using a gentle twisting motion to detach them without causing damage [20][22]. - It can differentiate between freshly picked strawberries and those from a supermarket, indicating its capability for quality control during harvesting [22]. Group 5: Future Implications - While the technology is not yet perfect, it represents a significant step forward in agricultural automation, suggesting a future where robots can efficiently and delicately harvest fruits like experienced farmers [23].
