The swiss light artist CAROLINE TAPERNOUX has used 3 robolink joint arms to create different light installations and test our products for possible projects. This was our first project with a worldwide successfull artist and it was a great pleasure for us. Please watch the sample video to get an impression of her work or visit her website: www.carolinetapernoux.fr
At the HMI trade show we released our strain wave gear (RL-S) as a product in addition to our worm gears (RL-D). The smallest version of the strain wave gear (RL-S-17-N11-00-28-020K0) is used for the fifth axis in the standard joint arms RL-D-RBT-5532S-XX and RL-D-RBT-3322S-XX. The RL-S-17 gear comes in two variations, both have a transmission rate of 28:1:
1. suitable for small motors (like NEMA11 stepper motors, holding torque = 0.1 Nm), output torque max. 1 Nm
2. suitable for slightly bigger motors (like NEMA17 stepper motors, holding torque = 0.5 Nm), output torque max. 3 Nm
The biggest available joint is the RL-S-20-N23-00-38-12000 with a transmission rate of 38:1. The maximum output torque is about 5 Nm, depending on speed and usage duration. Also here you are able to choose between two versions:
1. high-end: RL-S-20-N23-00-38-12030 (with PRT-01-20)
2. standard: RL-S-20-N23-00-38-12000 (with a standard PRT-02-20-AL)
attached are CAD data and the current data sheets: RL-S-STEP+Data
All gears can be purchased with igus stepper motors, initiator kits, encoder kits or customized to be combined with your motor!
our blog has been offline nearly 3 weeks due to internal revision.
It took us lonnger than expected and I am very sorry for the long absence. Please come back! Soon I will post new data sheets for our RL-D joints with some improvements and more technical data. In addition I will soon post new videos “how to mount a RL arm”.
Thank you for your patience!!
At this year’s MOTEK show in Stuttgart (GER) we will show the possibility to build 4 DOF robot arms with our motorized joints. 2 films at the end of this entry show 2 possible concepts:
1) “small” version with 4 joints size 30 – 30 -20 – 20, built with igus DC motors. No programming possible, just a joystick control.
2) “big” version with 4 joints size 50 – 50 – 30 – 20, built with igus stepper motors and a robolink gripper.
Please be aware that both arms are no sales products. They are examples of how a joint arm could look like. The connection parts are made of folded metal sheet parts. Please contact me for further questions in this issue (email@example.com).
Also attached our new catalogue (this version in GER with more RL-D infos and german list prices). Eng. version will follow soon.

And additionally 2 updated versions of tech. data sheets for symmetrical joints (version 101 with 2 PRT) and asymmetrical joints (version 102 with 1 PRT)

The team of Jan Kedzierski (Ph.D.) from Wroclaw University of technology now presents their NEW generation of the autonomous robot FLASH. It is (again) equipped with 2 pcs. 5 DOF robolink wire driven joint arms. They developpped their own drive technology for this robot based on DC/BLDC motors as an open source project. It will be published soon, I will link to their project then.
