METHODS AND DEVICES FOR TRANSMITTING EMERGENCY SIGNALS OVER DIFFERENTIAL SIGNAL LINES IN ROBOTIC SYSTEMS

Abstract

A robotic medical system can include a first node, a second node, and a first pair of electrical conductors for differential communication between the first node and the second node so that data signals are communicated between the first node and the second node as differential signals. The first node can include a first electrical circuit electrically coupled with the first pair of electrical conductors. The first electrical circuit can communicate emergency stop signals between the first node and the second node as non-differential signals over the first pair of electrical conductors.
