Exoskeleton customised in seconds with lubrication-free igus plain bearings

drylin linear systems and iglidur plain bearings provide lubrication-free adjustment of an exoskeleton for stroke patients. Many stroke patients worldwide suffer from hemiplegia (half-side paralysis). Exoskeletons such as Harmony from Harmonic Bionics can help rebuild the nerve tracts in arms and shoulders. In order to quickly adapt the robot-supported system to different body sizes in physiotherapy, the developers rely on the lightweight, lubrication-free and maintenance-free plain bearing technology from igus.

 

Rail guides of the drylin series T and a.o. drylin R round shaft guide allows easy adjustment of the system to the patient's body size, arm length and shoulder width. Due to the absence of external lubricants, the bearings are

• completely maintenance-free
• Clean and hygienic
• Lightweight due to plastic and aluminium

and thus optimally suited for medical technology. The design is so compact that it can be integrated into the slim design of the robot.

"Thanks to the use of the igus polymer bearing technology, the exoskeleton can now be adapted to the patient within seconds," enthuses Rohit John Varghese, Head of Research & Development at Harmonic Bionics.

drylin® T is THE linear guide system from igus - clean, robust, durable and directly available.
