+Franky currently supports four different impedance control modes: **joint position control**, **joint velocity control**, **cartesian position control**, and **cartesian velocity control**.
 Each of these control modes is invoked by passing the robot an appropriate _Motion_ object.
 
 In the following, we provide a brief example for each motion type implemented by Franky in Python.
