FAQ section renewed

We have renewed the FAQ section (currently in German, English/international will follow soon)! Link to the german FAQ site:


Next steps will be:

Update the download area, including step files for our “new” joints, update the different joint arms with the “new” joints, new catalogue (planned for April 2014 / HMI trade show). AT HMI we will also present a totally new joint concept besides the existing one. Be curious!


igus motion editor (open source software) new documentation

our open source software can be downloaded for free here:


The software can only be used with a certain hardware configuration (that consists of NANOTEC step motor drivers and an ATMEGA CRUMB 2560 Chip). The hardware is currently not part of our scope of delivery! The implementation steps to use the software is explained in this document:

 IME Config _EN_.pdf (628.79 kb)

German version:

 IME Config _DE_.pdf (631.67 kb)

Here is also a new video that shows the software functions:


angle sensors in the robolink joints

We have noticed, that for some people it is not clear how our angle encoders work and how to make use of it. Here are some facts about them:

1) we use incremental encoders from AMS (AS5304A), absolute encoders are not possible in the current design,

2) in order to define the ZERO position for each DOF, we use a hall sensor, beeing placed in the middle of each angular freedom,

3) that means: each robolink system has to be “initialized”, whenever the power is switched on,

4) the resolution of the encoders are:

29 (polepairs) x 160 (signals) = 4.640 signals per 360° = 0,078° for all rotationg motions of the size RL-50,

31 (polepairs) x 160 (signals) = 4.960 signals per 360° = 0,073° for all pivoting motions of the size RL-50,

62 (polepairs) x 160 (signals) = 9.920 signals per 360° = 0,036° for all motions (rot AND piv.) of the size RL-90 (Base joint),

you can find more information in our current catalogue on page 18 or in our documentation on pages 10-12 (=> pdf download in the support&service area of the robolink homepage).


 The FAQ list will be updated soon (it does currently not contain our new products).
