摘要：Actuators, systems, and methods for controlling tools are disclosed. Oneactuator includes a first motor, a second motor, and a controller. The first motor isoperable 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 thefirst threading and extending in a second helical direction opposite the first helicaldirection around the axis. The controller is in communication with the first and secondmotors. The controller is configured to control speed and direction of the first andsecond 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, andsimultaneously, rotating the second threading in a second rotational direction oppositethe first direction.
