I have loaded denso robot into Gazebo with a camera attached to its end-effector. You can see my files here.

Now, I have the robot end-effector command in the Cartesian space (x, y, z, theta(orientation around z axis)). I want the Jacobian matrix to transform the command I mentioned to obtain joints velocity. After that by integration I will have joints position and I can input these positions to the desired robot configuration.

My question is how to use IKFast from here to get the Jacobian matrix. Is it possible?

I don't know whether it is correct or not. As I understood, I need something like this page.

The distro of my ROS is indigo running on Ubuntu 14.04.

Given that denso vs060 package already comes with ikfast plugins, you could try swapping kinematics setting accordingly, something like the following in vs060_moveit_config/config/kinematics.yaml:

- kinematics_solver: kdl_kinematics_plugin/KDLKinematicsPlugin
+ kinematics_solver: vs060A1_AV6_NNN_NNN_manipulator_kinematics/IKFastKinematicsPlugin

I haven't tested so let me know how this works.

UPDATE) I'm getting to understand your situation better now that I've taken a look at your code. Maybe you should describe all the commands you use to run all the processes (by editing your original post), since I couldn't figure out how you run your IKFast plugin nor how you pass setpoint to the controller.

@i30s Thank you for your answer. Before you answered me, I had included files within my other packages from denso/vs060A1_AV6_NNN_NNN_arm_navigation/src/.

However, I still have a problem. Because when I include these files and set the setting for the cmake files I receive some errors and it cannot find the libraries related to these cpp files.

Would you please help me how to do that? If it is necessary, you can reach my files from gazebo_ros_denso/

@130s Thank you for your suggestion. Now I have set the IKFastKinematicsPlugin. Do you know how I can use this plugin with Gazebo (I mean how to edit my launch file)?

I think you've asked a new question (which is a good usage of this website :)) about IKFast and Gazebo so this question might be worth closed?

Ok. I will close this question.
