Our customer “Kuno Seebaß Medienproduktion” in Germany was one of our earlier beta testers. He built this nice camera crane with our joints. His aim is to optimize it now with more igus components. I like the video because it shows nicely our possibilities with robolink in these applications.

Some words about grippers in combination with our robolink joint arms:
Different grippers can be attached to our arm tubes. One common solution are pneumatic grippers. They are (often) lightweight and not so expansive. We can adapt several grippers from SCHUNK, FESTO, GIMATIC, FIPA and others easily. Please ask us. Also suction systems are (usually) no problem for us.
But often pneumatics are not possible to be used (for example in mobile robots). In that case, we have the choice between electrical grippers or our robolink wire driven gripper. The igus gripper can not be adapted to 4 or 5 DOF arms because of 2 reasons: 1) the leading of the wire through multiple joints causes friction, as the gripper is spring loaded, the spring may not be sufficient in strength to close the gripper properly. 2) the aditional bowden cable can not be leaded through the lower joint because of space restriction. The igus gripper may thus be combined only with 2 or 3 DOF arms. We are workink on a better solution in this case.
My favorite product in the moment for the combination with our system is the electrical gripper by GIMATIC called MPPM 1606 (2 jaws) or MPTM 1606 (3 jaws). It is lightweight and really easy to control. Datasheets in ENG/IT and DE/FR are attached. We can adapt the grippers and also lead the electrical cable through any of our arms. Please ask us in case of interest!
I have decided to write my blog in english from today on. Please poste a comment if you don’t like it that way! Thank you.
Attached 2 films as impressions from the german trade shows COMPAMED in Düsseldorf and SPS in Nürnberg in Nov. 2012:
In our new “Torso” you can see how the drive unit (motors) can be decoupled from the moving arm by bowden cables.
The initial endurance tests of the new joint at 180° pivot angle have been running for several days. All our tests run 24/7.
Once as 4DOF system:
and once as a pure 2DOF joint with 1.0 kg load:
At MOTEK and FAKUMA we have shown for the first time our new IME software. A common question from many prospective customers was: “How fast can I position with it?” Admittedly, the speeds of the arm shown there were not exactly breathtaking. Now that we have once again optimized the program a little, here is a film with the current maximum attainable speed of movement (with a further increase in speed, repeatability suffers to such an extent that the parts cannot be used properly). We reach a cycle time of approx 7 sec for a pick & place operation (55 sec for this process with 8x pick and place):
Another question was the possibility of using the arm in the clean room, or in areas with a lot of dust and dirt. The system is open, but there is always the possibility to “pack” the arm, here in the film is a very simple option with a protective shell of plastic (costs almost nothing, attached in seconds):
