Description

ARTUS 3 is Digity’s third-generation passive exoskeleton for fingers and thumbs. The system is designed to be worn on the fingers, potentially over protective gloves, to provide preventive support during tasks that may lead to hand or finger overuse, including repetitive pressing and finger overextension. Digity lists two main versions: a long-finger version and a thumb version; the product pages identify the finger model for index or middle finger support, while the thumb version includes a wrist strap, wrist connector, and magnetic wrist band.

The ARTUS is not a power-glove exoskeleton since it has no motors or actuators and is not powered. However, for what it achieves, it fits into the same category. This is a protective solution that safeguards from overextension of the fingers in repetitive work environments without sacrificing dexterity or mobility (as with any exoskeleton, the best way to understand it is to try it out for yourself).

The ARTUS stops the finger’s movement when the anatomical joint reaches its natural angle. It provides increased stability and control when pushing items in, typically in an assembly situation. The device is positioned for industrial use cases such as automotive manufacturing, logistics, and industrial assembly. Its value is in mechanical joint support and force redistribution without batteries or powered actuation, while retaining finger movement and tactile feedback through the DigiLock and DigiSkin elements. Digity states that ARTUS 3 is delivered fully assembled, is available in multiple sizes, and can be used as one exoskeleton per finger, with multiple exoskeletons worn at the same time depending on the work activity.

The designer prioritized user acceptance, and all efforts have been made to make the ARTUS feel like it is not even there when worn. It features a lightweight frame and a replaceable soft tip. A Digity Size Wizard acts as a user-friendly sizing tool.
