Patent attributes
An example robotic arm includes a base linkage and a first end effector connected to a second end of the base linkage through a first rotational joint. The robotic arm additionally includes a control arm. The control arm includes a first linkage and a second linkage, each having a first end and a second end. The first end of the first linkage is connected to the second end of the base linkage through a second rotational joint. The first end of the second linkage is connected to the second end of the first linkage through a third rotational joint. The control arm also includes a second end effector connected to the second end of the second linkage through a fourth rotational joint. The first, second, third, and fourth rotational joints are configured to rotate in or parallel to a first plane.
