Robot arm with articulated joint mechanism and gear arrangement
The patent US12036667B2 describes a sophisticated robot arm designed for precise articulation, particularly in surgical applications. The arm consists of two main segments connected by two revolute joints, allowing for complex movements. The first arm segment features a first longitudinal axis, while the second arm segment has a second longitudinal axis. The joints are configured to enable articulation about two distinct rotation axes that are non-parallel and intersecting. The joint mechanism includes a series of gears, including driven and drive gears, which facilitate the rotation of the arm segments. Notably, the design incorporates an intermediary gear arrangement that enhances the control over the arm's movements, ensuring that the rotation of one segment can be effectively managed without unintended motion in the other.
Further claims detail the specific configurations of the gears and joints, including the use of hypoid gears and bevel gears, which contribute to the arm's functionality. The patent also outlines the potential for a control unit that can respond to command signals, allowing for precise control over the arm's articulation. This includes the ability to negate any parasitic movements that may occur during operation. Additionally, the design allows for the integration of a third arm segment, which can also be equipped with tools, enhancing the robot arm's versatility in surgical settings. Overall, the patent presents a comprehensive approach to robotic arm design, emphasizing precision, control, and adaptability for complex tasks.
