This module contains properties required by the Modern Robotics library to perform
|
|
kinematic calculations such as the Joint Screw Axes and Home Configuration for each
|
|
X-Series robot.
|
|
|
|
Note that the end-effector is positioned at '<robot_name>/ee_gripper_link' and that the
|
|
Space frame is positioned at '<robot_name>/base_link'.
|

To calculate your own MR Description, check out the kinematics_from_description package:
