Robot Manipulator Control Example

Copyright 2017-2019 The MathWorks, Inc.


About the Example

This example uses the ROBOTIS OpenManipulator Chain robot to demonstrate the design of manipulator algorithms using MATLAB and Simulink.

This submission depends on files from the following Git repository: https://github.com/ROBOTIS-GIT/open_manipulator. The startupExample script will attempt to download them, but if there are any errors there is a pre-imported model of the robot manipulator so you can still run the examples.

Forward and inverse kinematics are demonstrated using functions available within MATLAB as well as supervisory logic implemented in Stateflow.

Robot geometries are imported to MATLAB using the "importrobot" function and to Simscape Multibody using the "smimport" function. For more information on these functions check the associated documentation pages.

Main Example Files

  1. openManipulatorIK.m

    This file shows how to import a robot from a URDF description and use the generated rigid body tree representation to implement forward and inverse kinematics algorithms

  2. openManipulatorWaypointTracking.slx

    This Simulink model uses Simscape Multibody as the environment and shows how to integrate the forward and inverse kinematics algorithms into Simulink to be used with Stateflow supervisory logic to pickup a ball, follow a trajectory, and finally drop the ball.

  3. openManipulatorBallTracking.slx

    This Simulink model builds on the waypoint tracking model and adds simple perception to track and catch a moving ball using a polynomial extrapolation of the ball trajectory.

  4. openManipulatorTorqueCtrlCfg.slx

    This Simulink model tests the closed-loop torque controller, in configuration space, using joint position commands (no inverse kinematics or supervisory logic).

  5. openManipulatorTorqueCtrlTask.slx

    This Simulink model tests the closed-loop torque controller, in task space, using end effector position commands (no supervisory logic).


Product Requirements

The required toolboxes to run all examples are:

  • MATLAB
  • Simulink
  • Robotics System Toolbox
  • Simscape
  • Simscape Multibody
