Research on Continuous Trajectory Planning for Ultrasonic Manipulator

Article Preview

Abstract:

For the large number of sampling points and high requirement of stabilization in ultrasonic testing,the dynamic performance of 5-dof manipulator was taken into consider: Firstly, the D-H notation and Newton-Euler were applied to set up the kinematic and dynamic equation for trajectory planning. Then the 4-3-4 polynomial which is continuous in displacement, velocity and acceleration, was used for continuous trajectory planning in joints space. Finally the trajectory based on time optimization with the constraint of velocity and acceleration including torque of actuator was validated.
