The Vision4Robotics Group at Vienna University of Technology (Team Dr. Walter Wohlkinger) is leading the project “Hobbit” in cooperation with our customer Hella Automation in Austria. Stefan Hofmann has equipped the robot with a robolink® joint arm (5DOF with angle sensors) and a FESTO adaptive gripper. They are using their own motors for the actuation. Here are the first test results on youtube:
First of all I want to thank all robolink® users and customers for interesting projects in 2012 and wish you all a happy and exciting new year 2013. The last year brought us projects from USA, China, India, Japan, Austria, France, Slovenia, Turkey, Macedonia, Italy, England, Switzerland, Poland, Brazil, Great Britain, and the Netherlands (besides Germany). The applications are very wide spread over medical and industrial applications as well as camera or sensor positioning, universities or research and development.
Today I would like to share 2 very nice links from Malte Ahlers (our beta tester since 2010) who explains very nicly the function of our angle sensors and how the signals from the angle encoder are working. This is written in German.
Thank you Malte!
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.
