How to directly generate inverse kinematics solution?

Hi, I am trying to use solve forword and inverse kinematics for my robot arm. I have a 6 DOF arm and already have the urdf file ready.

My propose is only forward kinematics and inverse kinematics. This is what I want to achieve: 1. Given each joints' angle, output the end effector's position/rotation. 2. Given end effector's position/rotation, compute the angle for each joint.

Can some one give me some hints on a simple way to do it? I am now following the MoveIt! tutorial and try to implememnt FastIK, but I think most of its functions are not needed for me, I do not really need to visulization or do motion planning. Is arm_navigation a better package(I need to change my ROS version to use it)?

Hi, for the IK solver(the .so file), is it generated by fastIK? Thank you so much!

Yes. The IKFast plugin generation process generates a C++ source file and a header. You can compile those into a .so file, or directly compile them into your own binary.
