In the video two different types of impedance control of the KUKA iiwa are shown: TCP and null space impedance. Furthermore, the bypassing of objects using impedance control has been implemented.

First, the two different types of impedance control are demonstrated. Different stiffnesses can be programmed around the individual TCP axes. Two different stiffnesses within a plane are shown in the video. On the other hand, there is null space impedance. In this case, the robot maintains the pose of the TCP and the elbow can be pushed away. As shown in the video, this can be used to bypass an object while maintaining the programmed TCP path.
