US 2025/0289136 A1 · REDUNDANT ROBOT POWER AND COMMUNICATION ARCHITECTURE

Abstract

An electronic circuit for a surgical robotic system includes a central power node, a first voltage bus that electrically couples a first power source to the node, a second voltage bus that electrically couples a second power source to the node, and several robotic arms, each arm is electrically coupled to the node via an output circuit breaker and is arranged to draw power from the node. Each bus is arranged to provide power from a respective power source to the node and each bus has an input circuit breaker that is arranged to limit a first output current flow from the node and into the bus. Each breaker that is arranged to limit a second output current flow from the node and into a respective arm. A breaker is arranged to open in response to a fault occurring within the respective arm, while the other breakers remain closed.

Dependent claims

An electronic circuit for a surgical robotic system that includes a surgical table and a plurality of robotic arms, wherein the electronic circuit comprises:

a main control circuit that is arranged to communicate with a host over a connection by receiving commands from the host, each command is for instructing one of the plurality of robotic arms to perform a movement, each robotic arm has a respective user-actuated switch that when actuated by a user enables the robotic arm to be moved by the user,
wherein the main control circuit is configured to:
override the respective user-actuated switch thereby preventing the switch from enabling the robotic arm to move due to an applied external force by the user while the host communicates with the main control circuit over the connection, and
in response to determining that the host has ceased communicating with the main control circuit over the connection, allowing the respective user-actuated switch to enable the robotic arm to move due to the applied external force when actuated by the user.

establishing, via a connection, communication with a host by receiving robotic control commands that are translated by a control computer from commands the control computer receives from the host, each robotic control command is for instructing one of the robotic arms to perform a movement, wherein there is a respective user-actuated switch on each of the robotic arms that when actuated by a user enables the robotic arm to be moved by the user;
overriding the respective user-actuated switch thereby preventing the switch from enabling the robotic arm to move while the communication is established through the connection;
determining that the host has ceased communicating;
and
in response to determining that the host has ceased communicating, allowing the respective user-actuated switch to enable the robotic arm to move when actuated by the user.
