4-axis robotic arm suits assembly systems

Robotics automation expert igus has introduced a new version of its 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, says igus, 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. Click on this link to watch a demonstration of robot arm during the recent Hannover Fair.
