Abstract
A surgical robotic system that includes a surgical table that is configured to hold a patient and a magnetic latch. The magnetic latch has a ferromagnetic plate, a permanent magnet that produces a first magnetic field and that attracts the ferromagnetic plate to thereby couple a robotic arm to the surgical table, and a cancelling coil, which when energized, produces a second magnetic field that opposes the first magnetic field to thereby uncouple the robotic arm from the surgical table.
