Patent attributes
The disclosed embodiments relate to systems and methods for a surgical tool or a surgical robotic system. One example system for detecting disengagement of a surgical tool, includes an end effector connected to and driven by cables of a tool driver, sensors configured to detect forces associated with the cables, and one or more processors. The one or more processors identify cable tensions derived from forces detected by the sensors, compare the tension to a threshold tension value, calculate a velocity norm value based on a vector including the velocity value for each of the cables, compare the velocity norm value to a statistic velocity threshold, and identify a disengagement of at least one of the plurality of cables based on the first comparison and the second comparison.
