Lite Jr Hand is a highly bionic robotic dexterous hand. Its core design features a highly bionic tendon-driven system. This design arranges all the driving motors in the proximal space of the forearm or palm, and transmits the motion remotely to the finger joints through high-performance synthetic fibers called "tendons". This architecture significantly reduces the mass and inertia at the fingertip end, enabling fingers to achieve rapid, dexterous and highly efficient movements, approaching the agility of a human hand. At the same time, the internal space of the released fingers allows for the integration of a higher density of joints and sensors, enabling complex dynamic intra-palmar operations such as turning pen holders and unscrewing bottle caps.
