Robotic Surgical System and Method for Communicating Synchronous and Asynchronous Information to and From Nodes of a Robotic Arm

摘要

A robotic surgical system is disclosed having a ring network for communicating information between a controller and nodes of one or more robotic arms. A communications protocol is described by which synchronous and asynchronous information can be communicated to and from the nodes of the robotic arms. Also disclosed are various aspects of a physical layer that can be used with the network.
