Surgical arm system with internally drive gear assemblies

Example embodiments relate generally to surgical systems. The system may include a first arm assembly having a first arm assembly body. The system may also include a distal elbow joint assembly secured to a proximal end of the first arm assembly. The distal elbow joint assembly may be configurable to provide the first arm assembly with a first degree of freedom relative to a first axis. The system may also include a proximal elbow joint assembly secured to the distal elbow joint assembly. The proximal elbow joint assembly may be configurable to provide the first arm assembly with a second degree of freedom relative to a second axis. The second axis may be different from the first axis. The first degree of freedom may be different from the second degree of freedom.
