Abstract
A robot arm () for end-effector motion. The robot arm comprises a first actuator () and a first kinematic chain from the first actuator to an end-effector platform, which gives a first degree of freedom for positioning the end-effector platform. The robot arm also comprises a second actuator () and a second kinematic chain from the second actuator to the end-effector platform, which gives a second degree of freedom for positioning the end-effector platform. The robot arm further comprises a third actuator () and a third kinematic chain from the third actuator () to the end-effector platform, which gives a third degree of freedom for positioning the end-effector platform. The robot arm also comprises a fourth actuator () and a fourth kinematic chain configured to transmit a movement of the fourth actuator to a corresponding orientation axis () for an end-effector (). The fourth kinematic chain comprises an orientation linkage () mounted to the inner arm-assemblage via at least one bearing (), and an orientation transmission (B,A,C,D,E;A;) mounted to the end-effector platform, wherein the orientation linkage comprises an end-effector rotation link () and joints () that provide at least two degrees of freedom for each end joint of the end-effector rotation link.
