Contents
A simple Cartesian trajectory controller that uses the new Cartesian trajectory definition.
Rationale
This controller shall get you started with executing Cartesian trajectories on your robot. It implements a simple action server for FollowCartesianTrajectory. There are currently two ways of execution, depending on the interface provided by the robot.
The table below highlights possible applications.
Hardware interface |
Primary application |
PoseCommandInterface |
You want spline interpolation in ROS but the OEMs driver to take care of inverse kinematics (IK). This variant requires the new Cartesian interfaces. |
PositionJointInterface |
You want spline interpolation in ROS and implement your own IK solver. The provided example uses the established Weighted Levenberg-Marquardt solver form KDL. This variant is compatible with current ROS-control so that you need not change your RobotHW abstraction. |
