Abstract: An exemplary self-locking actuator mechanism includes a floating plate and a linear actuator. The floating plate defines a first slot that includes a first central portion, a first jog extending laterally from a first end of the first central portion, and a second jog extending laterally from a second end of the first central portion. The linear actuator includes a shaft pivotably connected to the floating plate, and is operable to drive the shaft between a first shaft position and a second shaft position to thereby move the self-locking actuator mechanism between a first locking state and a second locking state.
