    Abstract: In one embodiment of the invention, a robotic arm is provided including a linkage assembly and a strap drive train. The linkage assembly includes first, second, third, and fourth links pivotally coupled in series together at first, second, and third joints to define a parallelogram with an insertion axis. The strap drive train includes first and second sets of straps coupled to the linkage assembly. As the linkage assembly is moved about a pitch axis, the first set of straps ensures the third link maintains the same angle relative to the first link, and the first and second set of straps ensures the fourth link maintains the same angle relative to the second link.

    Abstract translation: 在本发明的一个实施例中,提供了包括连杆组件和带传动系的机器臂。 连杆组件包括在第一,第二和第三关节处串联地联接在一起的第一,第二,第三和第四连杆,以限定具有插入轴的平行四边形。 带传动系包括耦合到连杆组件的第一组和第二组皮带。 当联动组件围绕俯仰轴线移动时,第一组皮带确保第三连杆相对于第一连杆保持相同的角度,并且第一和第二组皮带确保第四连杆相对于第二连杆保持相同的角度 链接。
