Abstract
Hobby servo motor linear actuator systems are provided. In certain circumstances, a linear actuator system includes a lead screw attachment mechanism and a lead nut. The lead screw attachment mechanism is configured to be rotatably connected to an output shaft of a hobby servo motor assembly. The lead nut is configured to move linearly along the lead screw attachment mechanism as it is rotated. The system is optionally either open-looped or closed-loop. The lead screw attachment mechanism has an outer surface that can include multiple different types of threads such as, but not limited to, gear teeth and screw threads. The hobby servo motor assembly may include one hobby servo motor or multiple hobby servo motors that work together.
Claims20
A linear actuator system comprising:
- a motor;
- a lead screw attachment mechanism with a threaded lower section and a threaded upper section and wherein the upper and lower section have different types of threads, and wherein the lead screw attachment mechanism rotates about an axis of rotation, wherein the axis of rotation is defined as the axis running lengthwise through the lead screw attachment mechanism;
- and
- a lead nut that is configured to move linearly along the lead screw attachment mechanism as it is rotated.
A linear actuator system comprising:
- a lead screw attachment mechanism with a threaded lower section and a threaded upper section and wherein the upper and lower section have different types of threads;
- a lead nut that is configured to move linearly along the lead screw attachment mechanism as it is rotated;
- and
- a feedback mechanism.
A lead screw attachment system, comprising:
- a rotatable shaft extending from a top surface to a bottom surface;
- a first portion of the rotatable shaft and a second portion of the rotatable shaft;
- wherein the first portion comprises a first threaded surface and the second portion comprises a second threaded surface;
- and
- wherein the first and the second threaded surface comprise different types of threading.
