 In this repo I have implemented two custum controllers:
 - `my_cartesian_position_controller`: a task space controller using the inverse kinematics porposed in https://github.com/ffall007/franka_analytical_ik/tree/main.
 - `my_cartesian_impedance_controller`: an impedance controller with variable parameters that can be set from another node. Additionally, it allows the user to perform a perturbation in the robot null space.
-
+- `motion_generator_node`: a ROS node that subscribes to target position and target impedance stiffness to generate a continuous versions of the signals to be sent to the robot controller. It uses [`ruckig`](https://github.com/pantor/ruckig).
 # :clipboard: Installation
 - Install [conda](https://docs.conda.io/projects/conda/en/latest/user-guide/install/index.html).
