more data for download (Catalogue, STEP, drawings)

I want to supply more data for you to be downloaded, especially about our RL-DC “standard arms”. Our standard arms include all joints, motors, connections (=c-shaped metal sheets), cables and chains. Attached our NEW catalogue (now also available in ENG), STEP data for our 8 standard configurations and also the related drawings with part lists. We have “small arms” (up to 1 kg, based on our joints RL-D-30 and RL-D-20) as 4 or 5 DOF and “big arms” (up to 3 kg, based on our joints RL-D-50, -30 and -20).


Version With motorencoder and Ini switch or “output encoders” (-AE). I will explain the difference in a later entry.

NEW catalogue and RL news for Hannover trade show

for this year’s HMI trade show (24.-28.4.17 in Hannover) we focussed on these topics:

  • NEW catalogue with price reduction for single joints (prices are shown in the catalogue, page 8-11),
  • NEW standard configurations for joint arms (RL-DC and RL-DQ), shown on page 46-47 in the new catalogue,
  • NEW output encoders as an option for all RL-D joints, they may replace the motor encoder AND the Ini switch. => prices for RL-DC and RL-DQ joint arms with the new output encoder are lower than the normal motor encoders / Ini options.

robolink at MOTEK, 4 DOF, new documents

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 (

Also attached our new catalogue (this version in GER with more RL-D infos and german list prices). Eng. version will follow soon.
