The igus® robolink® system stands for low-cost robots based on the modular principle. The online configurator can be used to implement solutions for the most varied applications. The electromechanical robotic arm RL-DQ is integrated in the robolink® range as a new element. It has an axis of rotation with an igus® stepper motor and is available in two models. The axis distances and the articulated arm geometry can be modified by adapting the connecting parts. By means of the new concept, in which the motor and joint are decoupled by a standard profile, the operating temperature is lowered and the payload is optimized by counter balancing.
