Output encoder vs. motor encoder plus INI

Martin Raak | 14. February 2018

Our customers can choose between motor encoders / Ini switches and igus output encoders (both incremental angle sensors). Motor encoder / INI (RL-D-RBT-xxxxx-BC): +) proven industrial standard, double ended signal transmission (A/A-, B/B-), high resolution (500 signals / motorturn * transmission of the joint) -) 3 cables per axis (motor, encoder, INI), reverse play of the […]


how to build a robolink arm (videos)

Martin Raak | 3. March 2017

we supply either components (joints, motors, cables,…) or complete electro-mechanical joint arms. compared to industrial robots, the composition of a robolink joint arm is quite easy and can be reproduced by “everybody”. We show the composition of a 5 DOF joint arm in 3 single video clips: assembly of joints, “motorkits” and “Inikits” (for 0-point reference), […]


igus open source soccer robot (with University of Bonn), first kicks…

Martin Raak | 9. November 2015

We have been involved in the development of a new open source teen size soccer robot for 2 years now (and the improvement still goes on!). The main development was done by the University of Bonn, institute AIS, Professor Sven Behnke, who also developped our open source robolink software IME (igus motion editor), igus contrubuted the […]


robolink joints and grippers

Martin Raak | 5. December 2012

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) […]


Feedthrough of draw wires

Martin Raak | 27. February 2012

For the series connection of joints, the 4 draw wires of the second (or upper) joint should be conducted through the first (or lower) joint. This feedthrough must be done in such a way that a movement of the lower joint does not alter the wire lengths of the feedthrough, which means Bowden cables are […]
