Forward Kinematics Characteristics of Camellia Fruit Dynamically Grasping Delta Robot Based on Screw Theory
摘要
Abstract
In order to meet the requirements of dynamic grasping of camellia camellia fruit,a forward kinematics equation of 3-R(SS)Delta robot was proposed based on screw theory to solve the complicated kinematic process of manipulator with traditional D-H parameter method.The structure of 3-R(SS)Delta robot is analyzed.Based on screw theory and exponential product formula,the forward kinematics of the robot was analyzed,and the pose transformation matrix of the robot was obtained.Finally,the Delta robot end-effector can accurately grab the camellia fruit moving on the conveyor belt by running the standard gate trajectory of the built Delta robot test platform.The calculated values of forward kinematics e-quation and the measured values of Delta robot test platform are compared and analyzed.The position error of the end-ef-fector position value is±0.01mm,which verifies the correctness and feasibility of the proposed method for constructing the forward kinematics equation of 3-R(SS)Delta robot.It lays a foundation for the follow-up research of trajectory planning of dynamic positioning.关键词
