The present invention generally provides methods and devices for controlling movement of an end effector, and in particular for causing mimicked motion between an input tool and an end effector during a surgical procedure. In an exemplary embodiment, a surgical system is provided having a master assembly with an input tool and a slave assembly with an end effector. The master assembly and the slave assembly can be coupled together by a mechanical assembly that is configured to mechanically transfer mimicked, rather than mirrored, motion from the input tool to the end effector. A floating frame is also provided and can be utilized with the surgical system. The floating frame can have a counterbalance that allows the surgical system to "float" above a patient and provide a weightless feel to movement of the surgical system. The floating frame can provides additional degrees of freedom for movement of the surgical system.
