Two years ago, Igus presented Robolink multi-axis joints for humanoid robots and lightweight automation. Now, a complete modular system is available ex-stock, including 19 new products.

These range from abrasion-proof and high-strength Bowden cables through to drive units and accessories for attaching flexible robot arms and routing of the Bowden cables in the arms. 

The Robolink joint module system for low-cost automation has been designed to combine design freedom with simplicity. The moving masses are kept as low as possible. For this, the drives and control module are decoupled from the movement mechanism and tools (e.g. grippers, hands, suction cups etc.). At the heart of the modular system are the lightweight, maintenance and corrosion-free joints with tribologically optimised plastic bearings, which are driven through cables and can rotate and swivel freely. The elasticity, light weight and possibility of a central drive are a real innovation in the field of low-cost robotics, according to the company.

Robolink won the iF product design award 2011.

Igus

Igus is the largest producer of reinforced plastic energy chains and injection-moulded polymer bearings. The range of polymer bearings includes Iglidur plain, Igubal spherical and Drylin linear bearings. They offer an excellent price-to-life relationship and are developed under the toughest conditions. They are oil, maintenance and lubrication free, low wear, resistant to dirt and dust, corrosion free and simple to fit. Igus also has the data to precisely predict the lifetime of these bearings within a specific application.

Energy chains are the umbilical cord of modern machines. They minimise downtime and protect, support and extend the service life of cables and hoses. The broad range incorporates more than 30,000 innovative, low-cost products. From the smallest ‘micro’ chain to the largest chain in the world, the E4.350, Igus energy chains are capable of long and short travel distances at high speeds in all axes.

Igus also has its own cable series, Chainflex, specially designed with energy chains in mind. They are highly flexible cables, offering a long service life and very small bending radii. A wide range is available, from small signal cables to large power cables, high-speed data cables and glass fibre-optic cables.

The company’s energy chains and Chainlflex cables can be delivered as a fully harnessed and pre-assembled Readychain system, cutting purchasing, warehousing and installation costs.
