An innovative building platform that prioritizes quality and safety, Studica Robotics offers a wide variety of robot parts, robotics kits, and cutting-edge electronics. This article will focus on creating an understanding of what an actuator does and how to choose from the variety of linear servo actuators available from Studica Robotics to best serve your robot. These actuators are unique because they allow for the adjustment of the extending shaft to a specific length.

Actuators are devices that cause an action to happen by converting electric signals into some form of motion. While the multi-mode smart servo creates a precise movement in an angular direction, linear actuators move a rod back and forth on a linear path. You could also use a regular motor or a servo motor with a rack and pinion linear slide set to achieve this, however, the linear servo RC actuators simplify the process. There are several options available, this article will help you determine the linear servo actuator that best fits your needs.

Comparing Linear Servo Actuators for Robots

There are several linear servo RC actuators available from Studica Robotics. We will share use cases for each.

1. 140-200:
   Offers a long stroke length and an extension/retraction speed of 6 mm/s allowing it to apply/withstand a max force of 190 Newtons. It is ideal for creating mechanisms that will handle a relatively substantial amount of weight, such as the base of a multi-stage lift.
2. 140-50:
   Also offers a long stroke length but has a faster extension/retraction speed of 13 mm/s allowing it to apply/withstand a max force of 95 Newtons. Ideal for creating mechanisms that look to operate and a quick rate of speed such as an extending arm or as a secondary or tertiary linear slide for a multistage elevator/lift.
3.  50-200:
   Offers a shorter stroke length of 50 mm and an extension/retraction speed of 6 mm/s allowing it to apply/withstand a max force of 190 Newtons. This is beneficial for handling a certain amount of weight making it ideal for creating mechanisms such as a cascading linear slide. This is a good tool for handling larger loads while utilizing minimal amounts of space.
4.  50-50:
   Also offers a shorter stroke length but a faster extension/retraction speed of 13 mm/s allowing it to apply/withstand a max force of 95 Newtons. This is useful for mechanisms that are smaller and require speed and precision than what is simply needed to carry a load. This makes it ideal for applications requiring minimal force such as the extension of a joint such as a small arm or gripper.
