TCP and null space impedance for bypassing objects with the KUKA iiwa
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.

IGMR Seminar: Mr. Ramsden – Fanuc Europe
Archivbild
Auch in diesem Jahr begrüßen wir Mr. Ramsden von Fanuc für ein IGMR Seminar. In diesem Jahr wird das Seminar leider virtuell stattfinden.
Zum dritten Mal in diesem Jahr dürfen wir Mr. Ramsden im IGMR Seminar begrüßen. Wie in jedem Jahr ist das Seminar auch als Gastvorlesung in das Modul Robotic Systems an der RWTH eingebunden. Mr. Ramsden wird in zwei Teilen wieder einen spannenden Einblick in Produkte von Fanuc bieten.
Die Veranstaltungen im Wintersemester 2020/2021 werden in Zusammenarbeit mit dem VDI-GPP-Arbeitskreis des Bezirksvereins Aachen durchgeführt.
Seminartermine:
Montag, 14. Dezember 2020 14:30 Uhr per Zoom
Donnerstag, 17. Dezember 2020 16:30 Uhr per Zoom

Haptic feedback system RePlaLink
At IGMR, the haptic feedback system RePlaLink (Reconfigurable Planar Linkage) is being developed. With this system, hand-actuated mechanisms can be haptically simulated and interactively synthesized. Furthermore, users can interactively synthesize these mechanisms. This should allow mechanisms with optimal haptic properties to be developed.
People frequently interact with hand-actuated mechanisms in everyday life, e.g., in car doors, furniture doors, reconfigurable furniture, or fitness equipment. Their haptic properties largely determine the perceived quality of these mechanisms. The RePlaLink (Reconfigurable Planar Linkage) aims to support the design and development of these mechanisms by applying haptic feedback systems based on virtual prototypes. The haptic simulation and synthesis method allows users to directly feel mechanisms’ kinematic and kinetostatic properties while operating the system. In addition, users can interactively modify these properties and receive direct haptic feedback. In the first video, the design of the RePlaLink, consisting of a planar five-link with an additional serial link for the handle, is shown.

The second video shows haptic simulation and synthesis using a kitchen cabinet door as an example.

Teaching the KUKA iiwa by manual guidance
The hand guidance of the collaborative robot KUKA iiwa is well suited for programming spatial points. This is possible both within a program and in the robot’s T1 mode.
https://youtu.be/v7D4yknlxJI
The video shows the manual guidance of the KUKA iiwa within a program. The robot can be guided by hand on the flange when the user presses the gray consent button. After releasing it, the program asks whether the current position is correct and should be saved. Any number of additional positions can then be added. At the end of the program, all stored room points are traversed in the taught sequence.
