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.
