NEWS for Hannover fair 2013: new base joint RL-90-BL1

The basic idea for this development is the wish to be able to build up a 6 DOF robot. For that purpose, a strong “base joint” was needed. It had to be stronger than the previous versions, and it should be able to lead the wires and cables of at least 4 more DOF inside, as well as additional pneumatic and/or electric cables.

The new joint is based on igus’ “PRT-01-50” slewing ring bearing. It has 2 DOF (degres of freedom): 1) rotation (+/-90°), 2) pivoting movement (+/-90°).

At this year’s hanover fair (08.04.13-12.04.13) we will present this base joint in a 6 DOF robot arm. Today you can watch 2 videos: 1) first kinematic test of the 2 DOF base joint RL-90-BL1 and 2) first test run of a 6 DOF installation, with 2 more robolink joints.

teach-in arm on ADAM torso and repeatability

once again I want to link to Malte Ahlers homepage and 2 of his Videos from his robot project ADAM A1. Now he is really running the 5DOF arm and he is using the 2nd one as teach-in arm. The movement speed and reaction time between left and right arm really impress me!

Serviceroboter “Hobbit” (TU Vienna) Project with robolink® arm

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:


robolink® angle Sensors (general description and technical details)

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!

robolink as camera crane

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.

“Dr. robolink” auf der COMPAMED 2012 in Düsseldorf

Mit Hilfe unseres Gelenkbaukastens haben wir innerhalb von 2 Wochen diesen Torso mit 2 Stk. 5-Achsarnmen für die Medizintechnikmesse gebaut. Die Steuerung der beiden Arme ist noch rudimentär. Zur SPS in Nürnberg sollen die Arme mittels unserer Software IME individuell und schnell programmierbar sein.

Hier sieht man, dass die Arme komplett von den Antrieben entkoppelt sein können durch die Bowdenzüge (im Film am Anfang oben an den “Schultern” zu sehen).

Tobias Abstreiter und sein Team haben diesen Demonstrator gebaut. Er kombiniert eine sehr kräftige Dreh- bzw. Schwenkachse mit einem einem robolink 2-Achs Gelenkarm. Die Basis ist eine Eigenentwicklung von Herrn Abstreiter. Sie ist mit einem igus Rundtischlager (PRT) ausgerüstet. Video auf youtube:
