On November 11, information from the Tianyancha App revealed that on November 7, Unitree Robotics Corp. was granted a patent for "A robot finger, robotic hand, and humanoid robot." This innovation falls within the realm of robotic technology. The robot finger design is ingeniously crafted with finger linkage units and transmission units working in tandem. The finger linkage unit is composed of proximal, middle, and distal shell segments, each equipped with a cavity and sequentially connected by rotating shafts on the gripping surface side. This configuration enables the finger linkage unit to grasp objects effectively through a sophisticated linkage mechanism. By positioning all rotating shafts near the gripping surface side, the design ensures a seamless, continuous gripping surface without interruptions. This feature significantly reduces the risk of the object becoming stuck due to excessive gaps during the gripping process, enhancing the robot's dexterity and reliability.
