Direct drive robotic arms
16 June 2015
New from igus is the next generation robolink D; a direct drive joint kit that is available in three different sizes and can be combined to form customised and configurable 1- to 4-axis articulated robotic arms.

Robolink D is intended for robot manufacturers, mechanical engineers and automation specialists, working in a variety of industries ranging from automotive production to medical technology.
Each low-cost joint kit comprises a PRT polymer slewing ring bearing, which is self-lubricating and therefore maintenance free, and worm gear, which is housed in plastic for added protection while ensuring weight is kept to a minimum.
For direct drive of the joint, a NEMA motor with the appropriate cables can be integrated in the axis and equipped with an encoder to send angle signals back to the controller. A variety of different grippers is available optionally.
Both the individual components and the pre-assembled system with construction diagrams are readily available. A fully-assembled robolink D system is available on request.
