Applications of Servo Motors

Controlling a machine's position and movement is essential to many systems. As such, servo motors, which apply the concept of servomechanism, are used. Controlling an aircraft’s tail using your typical DC motor, as an example, would be almost impossible to control and position accurately. These types of actions and commands, which require precise movement, need the precision of servo motors to succeed. Today, we'll be exploring the different uses hat servo motors have in modern robotics.

Servo Motors in Robotics

Robotics is a field of technology that heavily relies on servomotors. To demonstrate this, imagine a simple robot that picks and places items. It's a simple pick-and-place concept that's used widely in applications such as manufacturing and medicine.

To perform this simple task, however, precise movement is required. And that's what makes servo motors so useful - their precision is a vital component in the actuation of joints. This allows all movements calculated by the software is performed exactly as planned.

The robot's controller can keep on sending commands with the help of PWM data. This data provides precise control over the robot's actions and movements; something that isn’t feasible when attempted using DC monitors. Simple electronics projects are a great way to experience the application of servo motors firsthand. A simple and fun way to experiment on servo motors would be either to use Arduino kits or simply get a servo motor yourself.

Servo Motors in Conveyors

Another particularly helpful use case of servo motors is their use in both assembly and manufacturing. In particular, servo motors serve as vital components of the conveyor belts that bring items to a destination from another location. We can use bottles as an example of this, as they are filled with their respective liquids before being sent over to a packaging station.

The conveyor belts are powered to pass these objects along with the help of servo motors. Working in tandem with the filling station, the conveyor belt lets the bottles stop at just the right location. This allows the precise filling of the bottle. The conveyor belt then moves until the next bottle is ready to be filled, and repeats this process as necessary.

Servo Motors and the Auto-Focus Function of Cameras

One application you may have not expected is how digital cameras make use of servo motors. These days, cameras come with plenty of features; such as automatically change its focus on an object that’s being captured.

The way this works the object in the camera's sight is first inspected if it has enough sharpness. If it lacks the desired sharpness, the camera’s lens is readjusted automatically and precisely to get the sharpest possible image. This is done, of course, using an incredibly minuscule and precise servo motor.

Servo Motors in Robotic Vehicles

Robotic vehicles are widely used in complex and sensitive applications, such as military and industrial applications. These robotic vehicles primarily used servo motors for the movement of their wheels. In this case, angular movement isn’t as important as continuous rotation servos are used. What makes servos useful in robotic vehicles is their capability to speed up swiftly and then immediately comes to a halt precisely when told to. This also means that the velocity of the vehicle itself can also be controlled.

Servo Motors and Solar Panel Assistance

Solar power is an important source of power and is one of the first steps toward clean and renewable energy. Originally, solar panels were static, meaning that they would be stuck in a single position all day long. And since the sun’s position changes throughout the day, traditional solar panels wouldn’t be able to maximize the sun’s power.

Servo motors, in this case, can easily provide a solution - with solar panels installed on servo motors, the panels are able to position themselves exactly where they face at any time. The solar panel's efficiency increases significantly by simply following the path of the sun.

Both angle control and positioning are essential in many modern technological applications. The methods discussed here are some of the most widely-practiced uses of servo motors in technology today.
