Abstract
Embodiments relate to robotic arm assemblies. Robotic arm assembly includes an arm segment and end-effector assembly. Arm segment includes an elongated body which forms an arm segment central axis. End-effector assembly is securable to the arm segment. End-effector assembly includes an instrument assembly and first gear assembly. Instrument assembly includes an instrument and instrument gear. Instrument forms an instrument central axis. Instrument is for performing an action. Proximal end of instrument is secured to the instrument gear. First gear assembly includes a first primary gear and protrusion portion. First primary gear includes a second central axis formed through the first primary gear. Second central axis intersects with first central axis, instrument central axis, and arm segment central axis. Protrusion portion is secured to the first primary gear, and includes an opening. A portion of the proximal end of the instrument is provided in the opening and rotatable within the opening.
