Abstract
A system and method for rapid halt and recovery of motion deviations in a medical device includes a computer-assisted medical device having a first repositionable arm having one or more first repositionable elements, a second repositionable arm having one or more second repositionable elements, and a control unit communicably coupled to the first and second repositionable arms. The control unit is configured to control motion of the first repositionable arm and the first end effector based on a desired motion, monitor an actual motion of the first repositionable arm and the first end effector, determine whether the actual motion deviates from the desired motion by more than a predetermined threshold, and halt motion of the first repositionable arm and the first end effector, or of the second repositionable arm and the second end effector, when the actual motion deviates from the desired motion by more than the predetermined threshold.
