Inverse Dynamics with Recursive Newton-Euler Algorithm

Developed by: Haolin Ma.

Supervisor: Xinyang Tian.

Platform: Matlab 2019b.

In this work, the dynamic model of a 7-DOF robot manipulator has been established. Here are some notes about this script:

  • Using recursive Newton-Euler algorithm to calculate the inverse dynamic model of serial robot manipulator (only rotational joints) with modified DH parameters.
  • The parameters of the modified DH coordinates, inertia tensor, centroid coordinates and mass of each link can be found in the iiwamodel file.
  • No external force/torque.

Implementation

The code is implemented in MATLAB R2019b. Also, other versions of Matlab are available. Before running this script, pleas enter the input parameters: q (1×7), qd (1×7), and qdd (1×7). Cubic or quintic polynomials are recommended for planning trajectory. As a consequence, the output parameters are seven torques corresponding to seven joints of the robot manipulator.
