Robotic end effector assembly, system, and method of using the same

There is provided a robotic end effector assembly having a base configured to be connected to a robot. The base includes a robot adapter coupled to a base plate. The robotic end effector assembly further has a spindle support plate positioned substantially parallel with and coupled to the base plate, via two flexure members. The robotic end effector assembly further has a spindle disposed on the spindle support plate. The robotic end effector assembly further has an actuator coupled between the base plate and the spindle support plate. The actuator is configured to engage an actuator mount attached to the spindle support plate, to displace the spindle support plate. The flexure members inhibit an off-axis drilling motion, as the spindle support plate is displaced.
