Trade fair novelty Motek 2011: 5-axis robot arm with drive unit NEMA23

At the Motek’11 in Stuttgart, a rotary joint was presented, which extends the operating range of the existing double-jointed arm. The new rotary joint can turn +/-90° and is intended as first axis in an articulated arm.
The arm is equipped with a single-piece pneumatic gripper made of PA2200 as a prototype. The entire moving 6-axis arm weighs significantly less than 1 kilo, and can handle about 0.5 kg.
Recommended price of 5-axis arm (without grippers, sensors) = € 1,700
Price for a complete drive unit based on step motor (NEMA23) with 5-axis articulated arm: € 5,934

What goes around, comes around!

…and our pikchain® goes and comes around again, and again, and again: Endless!

What goes around, comes around!

We are going to place an add in 3 German technical journals. You see the pikchain® and a couple of words around the pikchain®. These words describe what the pikchain® is able to do, all automatically, all continuously, without empty strokes, without waste of energy, without waste of time and without waste of costs:

Stacking, picking and placing, cleaning, screening, recognizing, sorting, measuring, securing, laser, tagging, labelling, verifying, drilling, hoisting, lifting, filming, heating, cutting, weighing, branding, packing, etc. Probably, you have your own idea what the pikchain® can do for your application.

Of course, other machines can do the same. But, these machines don’t move. ‘The process of production is loosing time.
Time is money!
Why don’t you bring your tool on the pikchain®, for instance as moveable handling The smart combination of all components of the pikchain® allows to bring all energy, data and other medias to the tool, and it can run, and run, and run, in both directions, endless, stop and go, as you need it.Cool running, no idle running!

No slippery questions concerning slip rings


One of the important parts of the pikchain® is the slip ring and the rotary union or a combination of both. This part establishes the contact between the c-chain and the let’s say “outside world”

We got a lot of questions concerning this issue. We want publish some answers here:

Does igus® produce slip rings or rotary unions?  No!

Does the delivery package of the pikchain® also contains the slip ring or rotary union? As an option: Yes. igus® recommends buying the part yourself. We will tell you what and where you can buy the best part for you application.

Do rotary unions exist for Air, Water, and Hydraulics? Yes, nearly everything is possible. Most of time it’s only a question of space and price

Can I also transmit data with slip rings? Yes there are Slip Rings for all bus types on the market. We are pleased to consult you.

What about fibre optics? Are there existing also slip rings for this media? Yes, this is also available on the market.

What does a slip ring or a rotary union costs? This question is not possible to answer. Sorry. From a couple of hundred Euro up to several hundred thousands of Euros. It really depends on your application.

Are there combination of Slip Ring and Rotary Unions available? Yes, there are companies which harness your part according to your requirements.

Are there rotary unions on the market which are made for fiber optics? Yes, even for fiber optics.

How do I connect the slip ring to the c-chain? We will design and produce for you the connection.

You don’t find the answer to your questions? Don’t worry. Just call or E-Mail me. I am pleased to find the right answer for you. Christian Strauch +49 2203 96 49 7208.
