Servos

Servos are essentially small motors that can only rotate a set number of degrees via a 3-wire PWM connector.

Servos are used in FTC for high-precision applications that are low-load. Typically, servos have limited range of rotation (180°-270° is common). The output has splines, which are the rigid teeth that are on top of the servo.

Dual Mode

Dual Mode servos are servos that allow users to switch between two operational modes: Servo mode and continuous mode.

Servo Mode

Servos that can rotate to a given position based on a PWM (Pulse Width Modulation) input signal are called regular servos.

Continuous Mode

Continuous rotation servos are effectively just small motors in a servo form factor. They have no position control; instead, a PWM signal is used to control their rotation speed.
