Abstract
Actuators, systems, and methods for controlling tools are disclosed. One actuator includes a first motor, a second motor, and a controller. The first motor is operable to rotate a first threading extending in a first helical direction around an axis. The second motor is operable to rotate a second threading axially spaced apart from the first threading and extending in a second helical direction opposite the first helical direction around the axis. The controller is in communication with the first and second motors. The controller is configured to control speed and direction of the first and second motors to effect a desired pattern of axial and rotational movement of the tool. One method includes rotating the first threading in a first rotational direction, and simultaneously, rotating the second threading in a second rotational direction opposite the first direction.
