KALEM- a writing aid for patients with upper limb tremor

The present article deals with assistive technologies for influencing upper limb tremor. The introduction defines the basic concepts and theoretical knowledge needed to address the issue, which is the design of a writing aid for compensation of upper limb tremor. The method section describes the principle of operation through a block diagram of the device with a subsequent description of the basic components of which the device consists. The model itself was created in SOLIDWORKS CAD software and can be manufactured by 3D printing. A preliminary price calculation of individual elements and subsequently the price value of the complete equipment was also calculated. Emphasis was placed on the weight of the device and the final design.
