Applications of the Tower Pro Micro Servo 9g SG90

The applications of the SG90 are vast, thanks to its lightweight build and impressive torque. It has become a staple in the world of RC vehicles, particularly for those involved in the development of RC aircraft, boats, and cars. The precision it offers allows for accurate control of control surfaces, such as ailerons, rudders, and elevators in aircraft, as well as steering and throttle systems in RC cars.

Beyond RC vehicles, the SG90 is widely used in robotics projects. From hobbyist robots to educational kits designed to teach young engineers about the fundamentals of robotics, the SG90 provides a reliable solution for small-scale motors that require precise control. For instance, in a robot arm application, the SG90 can be used to control joints, allowing for smooth and accurate movements when performing tasks like picking up objects or assembling components.

Another key application of the SG90 is in camera mounts and gimbals, where its precision is essential to keep the camera steady and aligned, regardless of the motion of the vehicle or platform. In drone photography, for example, where high-definition footage requires stable camera movement, the SG90 provides that stability without adding unnecessary weight.

In educational environments, the SG90 is a fantastic tool for teaching students about the basics of servo motors, how they operate, and how they can be incorporated into different types of machinery. Its ease of use and low cost make it an ideal choice for educators aiming to introduce young learners to the world of robotics and automation.

Why Choose the Tower Pro Micro Servo 9g SG90?

So, why should you choose the Tower Pro SG90 over other servos on the market? First and foremost, it’s the combination of affordability and performance. The SG90 offers excellent value for money, providing an entry point into the world of servos for hobbyists on a budget without compromising on performance. The torque, speed, and precision it offers for its size make it one of the most balanced and reliable micro servos available today.

Additionally, the SG90 is incredibly easy to control, thanks to its standard 3-pin connection. This makes it compatible with a wide range of microcontrollers, including Arduino, Raspberry Pi, and other common DIY electronics platforms. With built-in feedback mechanisms, users can achieve precise control over the servo’s position, making it a reliable component for both beginner and advanced projects alike.

The Science Behind the Tower Pro Micro Servo 9g SG90

To truly understand why the SG90 is such a popular choice among hobbyists and engineers, it's important to break down the mechanics behind the servo motor itself. At its core, the SG90 is a DC motor that is paired with a system of gears to convert rotational motion into precise angular movements. The motor’s shaft connects to an internal potentiometer, which provides feedback to the controller to adjust the position of the servo in response to signals.

This feedback system ensures that the servo doesn’t simply spin continuously but instead stops at specific angles—making it ideal for applications requiring precise positioning. The SG90 works by receiving a Pulse Width Modulation (PWM) signal, which instructs the servo to rotate to a particular angle. The length of the pulse dictates the position of the motor shaft, ensuring a smooth and controlled movement.

One of the reasons the SG90 stands out in its class is the precision it offers with each movement. The small gears inside the servo help reduce backlash, which is a common issue in cheaper servos. This reduction in backlash ensures that the servo delivers smooth, consistent movements every time, which is a key factor for applications where precision is critical.

Customizing the Tower Pro SG90 for Your Projects

The Tower Pro SG90 can be customized in several ways to suit the needs of your project. For example, you can adjust the end stops to limit the rotation of the servo to a specific range if you only need a smaller movement. This modification is especially useful in robotic arms and camera gimbals, where you want to limit the movement to ensure the motor doesn’t rotate beyond the desired point.

Additionally, the SG90 is highly modifiable in terms of power input. Although it operates at 4.8V to 6.0V, some advanced users may opt to tweak the power input for higher torque or faster response times. However, it's important to note that pushing the SG90 beyond its rated voltage can reduce its lifespan or cause overheating.

Another customization that can be made is the use of different horn attachments. The SG90 comes with various servo horns, allowing you to easily adapt it to different types of mechanical linkages, such as arms, wheels, or control surfaces. These horn options ensure compatibility with a wide range of projects, from RC airplanes to custom robots.
