Abstract:

A medical robotic system can include a secondary brake release to allow a user to more easily move the arms of the robotic system when the system is in a power-off or fault state. The robotic system can include a joint and a brake mechanism that can limit motion of the joint. The brake mechanism can include a braking material, a first electromagnetic assembly, and a user-commanded release mechanism. The first electromagnetic assembly can disengage the braking material from an engaged configuration to a disengaged configuration. Further, the user-commanded release mechanism can disengage the braking material from the engaged configuration to the disengaged configuration independent of the first electromagnetic assembly.
