the bionic idea of robolink

Martin Raak | 3. September 2014

Why did we start with wire driven joints in the beginning of the robolink development? I would like to illustrate the basic bionic idea with this picture:   0 0


Connection hall sensor SS443A

Martin Raak | 15. March 2012

The hall sensor Honeywell SS443A has an open collector output.Switching a load or PLC requires a relay or optocoupler according to the following wiring diagram. The protective diode is necessary in the relay circuit.Due to the low response times, we recommend the use of optocouplers (e.g. Weidmüller 8950760000).   0 0


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 […]


Why triflex® R and no protective hoses …

Armin Gellweiler | 2. January 2012

The triflex® R energy supply system was developed for sophisticated robotic applications and compared to the protective hose, offers the following technical advantages.   1. Defined minimum bending radius Each triflex® R chain link has a stable circumferential bending radii stop. This ensures that the minimum bending radius of cables/hoses doesn’t fall short and the […]


Asymmetric robolink-version

Martin Raak | 28. July 2011

Asymmetric pivot angle arrangement: Displacement of the pivot angle of +/-90° to +130°/-50° This gives you a completely new area of operations with our robolink multi-axis joints. All other properties do not change compared to the original version. Both versions can be freely combined as desired. Get an overview in the following video. 0 0
