Linear actuators are a type of motor used to keep whatever they are attached to moving in a straight line or to apply a force. This means they can be used to push, pull, or lift, among many other types of movements.
They are commonly found in the full-scale world where smoothness in operation is needed, such as in various types of machinery or printers. Micro versions are a great addition to rc projects because they offer the same benefit of helping the object to move as desired.
There are a number of ways hobbyists can use this component to add more realism and additional functions to their finished project.
A Functional Option
A micro linear actuator is a valuable option for hobbyists because they are lightweight, are durable enough to withstand the movement the average RC vehicle undergoes, and can be digitally controlled. This makes them the perfect method of creating movement that is accurate with how the miniature vehicle would function in its full size.
While they can be used to allow the vehicle to remain straight during operation, they are also useful for other functions including dropping landing gear on planes, extending propeller blades, or moving buckets or beds on construction equipment.
Common Project Uses
Skilled hobbyists will discover that these actuators are useful when working on any rc construction kit and in an endless number of other projects. They can be used in many ways not originally considered. Common projects where they are used include:
- RC helicopters and planes
- RC automobiles
- Smaller scale construction equipment
- Multicopter drones
Becoming comfortable with this simple product will help to increase the realism of each project and add to the number of accessories the project can include. With their help, a multicopter can have adjustable lights and be able to raise and move an attached camera.
Whether it is rc plane for a hobby or a robot being designed for a school project, the addition of a linear actuator can reduce the cost and complexity of the project without sacrificing any of the features or freedom of movement. The many sizes and styles available make it easy to attach them to any type of equipment.
