Drivers for servos

Servo controllers are important components of any servo control system. A typical servo design is based on just a few components, which include an electric motor, a feedback circuit and a controller. In the controller circuit, the feedback circuit broadcasts information about the angular position of the servo so that the controller can send the appropriate signal to move the servo motor to the desired position. Servo systems with controllers operate using closed-loop feedback, which has advantages over open-loop in that it enables better servo response performance, reduces susceptibility to interference from control errors, and increases the stability of the overall system.

The latest servo controller technology

In times of rapidly advancing electronics and software, manufacturers have designed systems with even greater servo control capabilities. The Maestro USB series controllers from Polou feature very high control signal resolution and high stability for precise, vibration-free servo control. Among the unique features of the Polou controllers, there is also the option of adjusting the speed of changing the angular position of controlled servos, the possibility of switching off servos and advanced command mapping for optimised control. The Polou controller module can be controlled in three ways: Via a USB connection directly from a computer, a TTL serial port for interfacing with embedded systems (e.g. Arduino), and programmatically, with a script stored in the controller's memory. The controller channels can be configured as digital outputs, analog inputs and servo control signal outputs and ESC signal outputs for motor control, which, combined with the small size, allows the controllers to be used in remotely operated vehicles. High accuracy, a transient vibration time of less than 200 ns and built-in speed and acceleration control, make servos run smoothly and precisely. As a result, Polou controllers will work well in professional applications.

Servo control with Arduino

Servos are very useful devices and can also be controlled directly from an Arduino, as well as with the help of dedicated overlays. Using one analog input and one PWM output on the Arduino, we can control the servo in a proportional manner. In order for the PWM signal to control the servo, it must have a period of 20 ms and represent a low state for most of the time of that one cycle. At the beginning of each cycle, for a time between 1 and 2 ms, a high state must be present, with a time of 1 ms corresponding to a constant angular position and a time of 2 ms corresponding to a 180° rotation. This is the most advantageous control method. Remember that uploading the servo library to Arduino deactivates the PWM signal at pinout 9 and 10 (on the Arduino UNO and other boards with the same pinout). Controlling servos with Arduino with the servo library loaded is easy, but then each servo requires a separate PWM output. For more extensive projects, the Arduino-compatible multi-channel servo controllers from Adafruit will work great. Among them, 16-channel PWM controller from Adafruit, which generates PWM signal with 12-bit resolution, allowing simultaneous control of sixteen servos, using only two Arduino leads. In our store you are sure to find servo controllers to fit your own project.
