Direct drive robotic arms

Igus has introduced its 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 one to four-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 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 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 also available.
