1. A surgical end-effector, comprising:
- a) an assembly including an interface configured to be attached to a robotic arm, a tool-yaw motor, a tool-actuation motor;
b) a magnetic tool holder mounted to said assembly and being detachable therefrom, said magnetic tool holder being configured to automatically engage and release a surgical tool;
c) a tool-actuation mechanism mounted to said assembly and being detachable therefrom, said tool-actuation mechanism being configured to automatically engage and release a piston on the surgical tool, said tool-actuation mechanism being coupled to said tool-actuation motor; and
d) a tool-yaw drive mechanism mounted to said assembly and being detachable therefrom, said tool-yaw drive mechanism being coupled to said tool-yaw motor, wherein upon activation of said tool-yaw drive mechanism the surgical tool engaged by said magnetic tool holder rotates about said tool-yaw axis and wherein upon activation of said tool-actuation mechanism the piston of the engaged surgical tool is linearly retracted or linearly extended with respect to said end-effector thereby activating a tool portion of the surgical tool.
