Original Press Release:

IAI America’s New Rotating Joint Wrist Unit Adds More Capabilities to Single Axis & Cartesian Robots

IAI America made heads turn with the new 2-axis rotating joint WU Wrist Unit. The T-axis can rotate ±360 degrees and the B-axis has ±100 degrees of rotation.

Equipped with a battery-less absolute encoder as standard, IAI’s unique design made the units light and compact. The small S type weighs 1.6 kg and handles a maximum payload of 1.0 kg. The medium M type weighs 2.8 kg with maximum payload of 2.0 kg.

Diagonal approaches and tip swiveling, possible until now only with vertically articulated robots, can now be performed with the minimum required axis configuration by combining the wrist unit with single-axis and Cartesian robots. This is ideal for reducing the cost of equipment.

A Cartesian robot can move a wrist unit in long, straight lines making it capable of working in tight spaces. Many different combination patterns, number of axes and stroke can be selected to fit according to the application.
