With the robolink® joint modular kit, igus® enables the individual assembly of custom-fit low-cost robots for the most varied applications. Always at the lowest possible cost, with the appropriate technology. The new rotary-drive unit enables precise manual adjustment of the components. It is pivoted and rotated using lubrication-free, lightweight plastic gears; the mounting is also carried out with lubrication-free igus® plain bearings. Two adjusting wheels can be used to adjust the assembled instruments or devices. The compact rotary-drive unit is used wherever devices have to be set up infrequently, but with precision, in order to ensure a consistent seating for the application. The manual adjustment is also advantageous when electrical operation is not possible. A typical application example is the adjustment of small satellite dishes.
