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.

CASTOR.PL integrates robolink D in your application

Our polish customer CASTOR has shown their automation solution with our robolink D 5DOF joint arm at Automaticon show in Warszawa. Castor uses B&R control components and is able to solve YOUR application with their engineering. Communication via iPad is a possible option. For further information, please contact

New data sheets for RL-D joints

we run regular lifetime tests with our gears in our lab. Based on these tests, we did some inside changes in our gears, most important is the change of gear geometry and gear pulley material during the last months (from iglidur J to iglidur A 180). By this, we improved lifetime and friction (efficiency) in the joints. Please find attached NEW data sheets for our joints, now also including the current standard transmission ratios we can supply from stock (from 1:5 up to 1:70).

how to change worm wheels (video)

the main differences between our gears and standard metal gears are:

ours are lubrication free (no grease, no oil) and very lightweight due to plastic and aluminium parts instead of steel, brass or bronze (=standard design). The same is valid for the bearings we use on the output (igus PRT = polymer round tables).

This makes it very easy to open our joints, in case worm wheels need to be exchanged (reasons for exchange might be: broken gear teeth due to overload on the output or the need to change gear parts due to changing conditions like temperature,…). The video shows how to proceed:


how to build a robolink arm (videos)

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:

  1. assembly of joints, “motorkits” and “Inikits” (for 0-point reference),
  2. assembly of an arm
  3. cabling of the arm

these films shall help you to understand the idea of our joint kit and how easy it is to change, modify or configure our arms.
