Patent number: 11602403Abstract: A system for controlling a robotic tool includes a memory that stores instructions and a processor that executes the instructions. When executed by the processor, the instructions cause the system to perform a process that includes monitoring sequential motion of tissue in a three-dimensional space. The process also includes projecting locations and corresponding times when the tissue will be at projected locations in the three-dimensional space. An identified location of the tissue in the three-dimensional space is identified based on the projected locations.
