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 lead screw attachment mechanism that is configured to be rotatably connected to an output shaft of a hobby servo motor assembly;
- 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:
- at least one hobby servo motor having an output shaft;
- an attachment mechanism rotatably connected to the output shaft;
- and
- a lead nut that moves linearly along the output shaft.
A linear actuator assembly comprising:
- a lead screw attachment mechanism having an outer surface, a first portion of the outer surface having a first type of threading, and a second portion of the outer surface having a second type of threading;
- and
- a feedback mechanism that is configured to functionally engage the lead screw attachment mechanism utilizing the first type of threading.
