Samsung Electronics Co. Ltd. Files Patent for Advanced Joint Device for Robots

Strategic Insights

— 2 min read

Samsung Electronics Co. Ltd., a renowned technology company, has filed a patent for an innovative joint device designed for robots. This device, filed by inventors Hwang, Cheoggyu and Kim, Jinwoong, on January 12, 2023, and published online on July 8, 2025, offers a unique solution for robots requiring two-directional degrees of freedom of rotation.

The joint device features a first shaft, a second shaft disposed perpendicular to the first shaft, and three friction wheels. When the first friction wheel and the second friction wheel rotate in the same direction, the third friction wheel rotates in a pitch direction, and when they rotate in different directions, the third friction wheel rotates in a roll direction. The device also includes a driving system with two motors and a pulley system, allowing for precise control and movement.
