| 英文摘要: |
| In order to accelerate the fruits and vegetables picking by intelligent robot instead of humans, and to improve the quality and efficiency of the
operation, a flexible and humanoid hand end effector for picking fruits and vegetables was proposed. The end effector is driven by the mode of two joint full drive, and through the 2
joints (proximal finger joint 1 and distal finger joint 2) cooperation with each other to hold the fruit like human hand. A static model of envelope grasping mechanism of two joint full drive
finger was established to obtain the relation between the input torque and the contact force in the linkage mechanism of the proximal finger joint and the control of the force applied to the
fruit and vegetable to reduce the damage of fruits and vegetables. Finally, the simulation experiments of the whole mechanism based on SolidWorks was carried out to verify the rationality of
the mechanism. The end effector of the fruit and vegetable picking machine has high versatility and can compensate the robot image recognition error. |
