Abstract: A robotic surgical system comprises a horizontal platform to support a patient, a rail positioned about the horizontal platform, a carriage operatively coupled to and configured to translate along the rail, and a robotic arm operatively coupled to the carriage and translated about the patient by the rail. The robotic arm is configured to operate on the patient in a variety of positions provided by the translating carriage. The rail provides a rounded path for the carriage, such as a U-shaped path. The U-shaped path may comprise a first leg and a second leg, the first leg longer than the second leg. Furthermore, the system may comprise a plurality of carriages operatively coupled to the rail and a plurality of robotic arms. Also, the system may further comprise a central base which the horizontal platform can articulate relative to, such as by translating horizontally or vertically, rotating, or titling.
